Do you want to have a stronger and more beautiful body? Then the best thing to do is get on your feet and start doing the resistance training.

What Is Resistance Training?

Resistance training involves activities that use weights, machines and even body weight to work out the muscles properly. It is also known as strength training or weight training. This can be very helpful in achieving a healthier body.

This kind of training is usually associated with athletes who have to build up their bodies. Most people would think that when resistance training is done, the body will grow bigger. Actually it will not. Resistance training is simply about increasing the strength of the body, not its size.

Actually, this can be practiced by anyone. It basically builds and tones the muscle to give the body a better look. This training program is even very much advisable to the elders. The usual training programs undergone by the elders are standing free-weights resistance or the moderate-intensity seated machine training.

How Does Resistance Training Work?

A resistance training program will include the use of various exercise equipment and machines like the bench press, dumbbell or barbell. When the equipment is used, the muscles of the body will be pitted against the weight. The cells of the body will then adapt to the extra weight. This will then result to hypertrophy or the enlarging and increasing of the nerve cells to help in the muscle contraction.

Before doing any resistance training, it will be best to consult first with the doctor. This goes especially for people who have medical conditions or are overweight. This kind of training is not something that you can explore on your own. You have to know the proper equipment for the needs of your body. The body must also be conditioned first before taking in the weights.

Resistance training can also be done without resorting to the equipment. Doing push-ups is one good example. You can do it just about anywhere where there is enough space for you to move. This time it is your own body weight that will be pitted against the muscles. So those who are a bit constrained in the budget can still do resistance trainings.

What Are the Benefits of Resistance Training?

1. Increase Bone Mineral Density
Bones are constantly remodeling, meaning the tissues break down at the same time they build up. The peak of remodeling takes place during puberty. However, as a person ages, there may be problems with the bone mineral density as the remodeling may not be as active anymore. This is especially a problem to post-menopausal women.

Bone mineral density is usually supported by the hormones. To address the problem of not having the hormones to maintain the bone mineral density, physical activity is the next best option. Resistance training is one physical activity that can address this.

2. Increase Strength
Strong bones and strong muscles will be developed as you undergo the resistance training program.

3. Increase the Range of Activities
When your body is strong enough to carry some considerable weight, then definitely you will also be capable of doing more strenuous activities. You are less likely to be lazy and you can live a more active lifestyle.

4. Reduce the Body Fat
Pitting the weights on your muscle will definitely give it the body the exercise it needs and get rid of the undesirable fats. Thus expect the tone of the body to improve. Even more, expect the body to look better, to be leaner.

5. Improve State of the Elders
For the elderly, undergoing a resistance training program will help improve their health and decrease the risks brought about by the age. They can be more independent, without needing to rely on other people for doing simple things. Being able to do so will also decrease the risk of injuries in the elders

6. Improve Heart Condition
Regularly doing resistance training can result to a lowered heart rate and lowered blood pressure, especially after exercise. The risk of heart diseases is reduced to a considerable extent.

This kind of training however must be properly done. It requires commitment and consistency. It will have to be done in a regular basis, following a schedule that the doctor or the physical trainer would recommend. If done incorrectly, the benefits of the program may not be enjoyed and it can even result the injury.

The key here is to simply take your time. Do things one step at a time correctly. As your body condition improves, then move on to more challenging tasks. The strength of the body and its overall look are at stake in the resistance training. So you better be sure to do it properly.

Vitamins and minerals can be absorbed by the body in a number of ways. They first enter our body through the food we eat. Secondly, we can take vitamin supplements to increase the amount of pertinent vitamins and minerals. There are different methods of taking medication and one of the most common methods is absorbing it in its liquid form. Do the advantages of liquid vitamins far outweigh its disadvantages – if there are any? Read on and find out.

Better or Easier Absorption for Kids
Although liquid vitamins may taste worse than vitamins in flavored, chewable tablet forms, they are however easier to absorb. There are numerous cases in which children have problems with choking, breathing and swallowing simply because of their inability to absorb medication or vitamins in this form.

This is the same problem as well for adults who have lost their ability to control their jaws or are unable to digest anything that is not in liquid form.

Liquid Vitamins are More Effective
Because of its form, liquid vitamins can be assimilated immediately into the blood stream for a more systemic administration of the vitamin and its average absorption rate is approximately 90 to 98%. It is also three to five times more concentrated than vitamin pills and this lead to higher bio-activity and greater therapeutic benefits.

The Link between Antioxidants and Liquid Vitamins
Have you ever wondered whether or not liquid vitamins contained oxidants as well? Vitamins E, C and A are examples of antioxidants and they are commonly found in vitamin supplements but what about liquid vitamins?

And the answer is an absolute YES. Liquid vitamins must in fact contain such antioxidants or they’ll prove to be ineffective compared to other vitamins. Remember that the most important of all antioxidants – Vitamins A, C and E – are not internally produced by the body so they must be a regular fixture in our diet. Antioxidants are our main defense against effects of damaging oxidation reactions. Antioxidants are our best weapons against suffering from any form of cancer. Without it, we are basically weaker and less healthy.

Liquid Vitamins versus Digestive Acids
One reason why people refuse to acknowledge the benefits of liquid vitamins is because of the supposed destruction by digestive acids of any vitamin or mineral that it does not recognize as part of the process of digestion. The opposite is, in fact true. Our digestive system actually prefers or is able to better absorb liquid vitamins and minerals rather than those made in pill or capsule form.

A vitamin pill or tablet has to be digested completely before it can benefit the human body. It must be broken down into absorbable nutrients or only up to thirty percent of it will be absorbed by the human body. Liquid vitamins however provide a better and easier solution for the digestive system. Because it does not depend in any way on mechanical digestion, an estimated 90% of it can be absorbed directly by the body.

It’s vital to remember that digestion does not mainly function to destroy vitamins and minerals but rather to transform them into substances it can use to improve the general constitution of the body.

Liquid Vitamins: Toxic or Not?
Another problem posed is the amount of colloidal minerals found in liquid vitamins. Are they harmful or not?

In truth, even plants and fruits contain a trace of such minerals in them. Apples, for instance, contain 3-5 mg of aluminum as it’s one of the most abundant elements that can be found in the surface of the Earth. But do you hear anyone telling you that apples are dangerous to your health? On the contrary, what we are more likely to hear is that an apple a day keeps the doctor away.

And so it must be with liquid vitamins as well. Containing a slight amount of colloidal mineral doesn’t mean it’s bad for our health right away. Colloidal minerals, are above all else, naturally occurring elements and can not therefore be avoided.

You Have a Choice
At the end of the day, however, it’s still up to you whether or not you wish to take vitamin supplements in liquid or solid form. What really matters is what you prefer and which will ultimately work better for you.

When the words oils and fats are mentioned, health-conscious individuals tend to run for cover. What they fail to realize is that there are good fats and bad fats. Complete avoidance of intake of oils and fats would actually be detrimental – rather than beneficial – to their health.

The Truth about Fish Oil
Essential fatty acids must always be part of our daily diet – without them, we take one step closer to our deaths. Essential fatty acids are divided into two families: omega-6 EFAs and omega-3 EFAS.

Although there are only very slight differences to distinguish the two groups of essential fatty acids from each other, studies have revealed that too much intake of omega-6 EFAs can lead to inflammation, blood clotting and tumor growth. The good news, however, is that the opposite is true for omega-3 EFAs. Omega-6 EFAs can be found in vegetable oils while omega-3 EFAs can be found in fish oils among other foods.

Omega-6 vs. Omega-3
Physicians and scientists are of the same opinion that the cause behind increasing cases of heart disease, hypertension or high blood pressure, obesity, diabetes, premature aging and certain kinds of cancer is none other than an imbalanced intake of omega-3 and omega-6 EFAs.

As mentioned earlier on, omega-6 EFAs can be found in vegetable oils. This includes but is not limited to corn oil and soy oil, both of which contains high amounts of linoleic acid. Omega-3 EFAs on the other hand can be found also in marine plankton and walnut and flaxseed oils. It should be significant to take note that fatty fish and fish oils contain eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), fatty acids that have been observed to provide many benefits to the human body. In the early 1970’s, a study on Greenland Eskimos have revealed that one of the major reasons why they rarely suffer from heart diseases is because of their high-fat diet (mainly composed of fish).

The two essential fatty acids, EPA and DHA, are also helpful in preventing atherosclerosis, heart attacks, depression and various forms of cancer. Fish oil supplemented food have also proven to be useful in treating illnesses like rheumatoid arthritis, diabetes, Raynaud’s disease and ulcerative colitis.

Other Benefits of Fish Oil
There are a lot more illnesses and situations in which intake of fish oil has proven to be significantly beneficial.

Making the Heart Healthier
The heart is inarguably one of the most important parts of our body and having an unhealthy heart means having to suffer a rather limited lifespan. Naturally, it’s in our best interests to keep our hearts happy and healthy and one way of doing that is eating food that contains fish oil.

In Athens, Greece, for instance, a study was made to show if there was a direct relationship between high fish diet and inflammation of blood vessels. The results revealed that those who ate more fish than the others had a lower level of C-reactive protein and interleukin-6, factors that are commonly used to measure likelihood of blood vessel inflammation. These benefits remained even when the various risks associated with high fish diet were taken into account.

Fish to Become Thin
In Perth, Australia, a study had revealed that fish consumption can be used against hypertension and obesity. Researchers of the UWA (University of Western Australia) have discovered that a weight-loss diet which includes a regular amount of fish consumption can be quite effective in reducing blood pressure and improving glucose tolerance.

Fish Oil to Combat Asthma
People suffering from respiratory problems like asthma tend to be perceived as unfit and unhealthy. They should now be pleased to learn that certain studies have revealed the benefits of fish oil for asthma-burdened-individuals. Statistics show that approximately 20 to 25% of children today suffer one form of asthma or another at a certain point in their lives. And certain evidence reveals a regular diet of food with high linoleic acid content as the reason behind it.

Researchers of UW (University of Wyoming) conducted a study by subjecting a number of children to a high-fish diet while others continued with their regular diet. Results revealed that the participants who ate more fish were less prone to asthma attacks and were able to breathe more easily as well.

Consult Your Nutritionist Now
Nothing is good when consumed or used excessively but complete avoidance of a particular food type is equally harmful as well. Ask your nutritionist for the right amount of fish intake for your age and health status.

It seems to be a little disgusting when you are detoxing or cleansing. Your body shows some signs that you have built up toxins. These toxins can affect your whole body fitness and health.

There are times that you feel sluggish and feel the stressful. Your body may experience continuous aching, diarrhea, constipation, and feeling of clumsiness. Rapid weight gain and the incapacity to lose the excess weight can also be signs of having toxins in the body.

Moreover, the toxins found in the body are found and stored on your fat cells. For Americans who are taking the usual American diet, a person may consume 70 trillion garbage cans for each cell. In detoxing your body and cleaning that unwanted garbage in your cells, you should pay attention on your elimination organs.

There are particular organs in your body that deal on cell waste management. These organs play a major role in the detoxing process for a fit and healthy body.

1. Your liver is the organ that recycles the unwanted chemicals in the body. It sorts out the toxins and places them to the organ for elimination during the process of circulation. The principal elimination organs will back up the liver on where these toxins will be stored and then eliminated.

2. The lymph glands also play an important role in eliminating the toxins. A network of tubing brings out the excess waste of the cells from the body and to the final eliminating organs. The appendix, thymus, tonsil, and spleens are major lymphatic glands that help the major organs of the body in cleansing and detoxing.

3. The kidneys help in the water management of the body. They are the ones that keep the good chemistry of the blood alkaline by eliminating the dissolved acid waste. You can help your kidney to function very well by drinking plenty of water. It is much better if you drink fresh alkaline juices and purified water. You may take ½ ounce of alkaline everyday to see positive results on your body weight.

4. The lungs are the organs that keep the blood air purified. They allow the oxygen to go directly to the bloodstream. It is also responsible in removing waste gases that are found in every cell of the body. Deep breathing and fresh air is very helpful in keeping the lungs healthy and free from toxins. If you are in the urban area, it is recommended that you find an oxygen rich area where you can perform deep breathing.

5. The colon is a solid waste management organ in your body. Medical practitioners have found many peolpe that may have an 80-pound mucus and rubber like solid waste that are found on the walls of the colon. Detoxing and cleaning the colon can be a real tough thing to do. However, having a free waste colon can certainly provide you good benefits of having a clean and healthy body.

If you are experiencing some signs of detoxification, you may try doing a regular walking exercise. Exercise is a good key in having a fit and healthy body. Many diet doctors also suggest that you drink plenty of lemon water. This is an effective way of maintaining a very good circulation and can increase the rate of detoxification inside the body.

Around 8,000 to 10,000 years ago, an unknowing soul accidentally let the juice of a sweet fruit - perhaps dates, figs, or even grapes ferment. The outcome: The sugar in the juice fermented to alcohol and wine was born. Since then, wine has been a staple beverage of many cultures. In Mediterranean countries, for instance, people sip wine daily with their meals, and it's believed to be one of the reasons heart-disease rates are low in this European region.

The notion that wine may be good for you is not new. Hippocrates, the father of medicine, referred to wine's attributes in his writings. And today, we know from many research studies that people who drink one or two glasses of wine daily with meals have lower death rates from heart disease and stroke.

Wine's health benefits appear to be twofold. The alcohol in wine, whether red or white, helps protect the heart; and the phytochemicals from the skins of grapes that end up in wine, especially red varieties, also provide protection from heart disease. These two "attributes" raise wine above other alcoholic beverages as a good- for-you drink. But as with anything, especially alcoholic beverages, moderation is the key. In this case, more is definitely not better.

Wine provides heart-healthy benefits. Grape skins contain a class of phytochemical called flavonoids. When red wine is made, the juice ferments with the skins allowing the flavonoids to leach into the wine. This process imparts both flavor and color to the wine. As a result, red wine contains flavonoids. (Grape skins are removed during the making of white wines, hence a very low flavonoid content.) These flavonoids help take care of your heart by protecting your LDLs and preventing dangerous blood clots. (Red or purple grape juice also contains flavonoids but only about one-quarter to one-third the concentration found in red wine.)

Research from the University of Wisconsin shows that red wine flavonoids also help keep the blood platelets from becoming sticky. This means blood clots are less likely to form, lessening the chance of a heart attack. The heart-healthy benefit of wine, primarily red wine, should be put in perspective. Studies that confirm red wine is good for the heart also reveal that those people also typically consume their wine with meals.

Therefore, the timing and amount may be crucial in how both alcohol and flavonoids impact heart health. In fact, in regions of Italy and France where heart disease is relatively low, moderate wine drinking is learned from an early age around the dinner table. Displays of drunkenness are virtually nonexistent, and finding pleasure in sipping wine slowly at meals is typical.

However, drinking an entire bottle one night and then dividing this by seven for a "moderate" average over the week is missing the point. The key here is moderation at all times. Before you rush out and buy a bottle of Merlot, proceed with caution. Alcohol consumption, and this includes red wine, is not without risks.

Regular drinking may impair mental function and memory. Moreover, heavy drinkers (4 to 5 drinks or more per day) have a greater risk of developing hypertension. This increases the chance of stroke and kidney failure. Heavy drinking also increases the likelihood of liver damage and liver disease. In addition, keep in mind that alcohol consumption increases the risk of injuries and accidents at work and on the roadway.

For women, the increased risk of cancer (particularly breast cancer) with drinking must be weighed with the potential benefit of lowering the risk of heart disease. Talk over your cancer risk with your physician before you decide on moderate alcohol consumption (one drink per day).

Tai Chi: The most popular form of exercise in China. It developed as a "soft" martial art in the early 1200s. It is now a component of traditional Chinese medicine and is practiced primarily for its health benefits. Tai chi consists of a precise sequence of slow, graceful movements, accompanied by deep breathing and mental attention to achieve balance between body and mind and to focus the qi (pronounced chee), or vital energy. A practitioner's weight is shifted while the body is kept stable and upright.

Because it can be practiced anywhere and by people of any age and physical ability, tai chi is an attractive exercise program for disabled or elderly people. Tai chi involves an energy expenditure equivalent to that of other low to moderate aerobic activities. Exercises can be completed in fifteen to twenty minutes and are ideally practiced twice a day.

Practitioners of tai chi report mood enhancement and physiological changes similar to those produced by other moderate forms of exercise. However, tai chi is uniquely beneficial for improving posture and balance. Because of this effect, tai chi may help prevent injuries from falling. Significant studies on this technique include the following:

One of the earliest studies done in 1982 by Dr. Lansheng Gong of the Shanghai Medical College, studied the electrocardiograms of one hundred tai chi practitioners and found benefits. However, he also noted that these beneficial effects did not seem attributable to the amount of physical exercise, and other mechanisms needed to be discovered.

A 1992 study by Dr. Shuk-kuen Tse and Dr. Diana M. Bailey concluded that tai chi helped improve balance among people who were largely sedentary. From a 1995 study by Dr. Jinshin Lai and associates, elderly tai chi practitioners showed significantly improved cardiorespiratory function, compared to sedentary subjects. However, another study found that tai chi conferred no significant changes in blood pressure or heart rate.

An ongoing study by Dr. Kate Long at Stanford University School of Medicine will determine the potential applicability of tai chi for patients suffering from arthritis and fibromyalgia. A second study by Dr. William L. Haskell will evaluate the role of tai chi as compared to traditional Western exercise in improving the physical and psychological health of older men and women.

Well-designed research seems to conclude that tai chi, as a form of exercise for elderly people, may prove a valuable part of health maintenance programs, both for preventing falls and for maintaining fitness.

Qi Gong: Qi Gong (pronounced chee gong) is another ancient Chinese exercise involving physical movements and breathing exercises. An element of traditional Chinese medicine, it is used to circulate internal qi, which, according to Chinese medicine, is the vital energy that flows through the body in a system of subtle channels known as meridians. Qi Gong is intended to direct the internal qi, and promote health.

There are two basic kinds of Qi Gong, internal and external. Internal Qi Gong is used for self-healing and health maintenance. It can be performed in any position, including standing, sitting, walking, or even lying down. External Qi Gong is practiced by Qi Gong masters or Qi Gong doctors, and involves projecting the qi energy out of one's body to heal another.

In China, Qi Gong is used for disease prevention as well as therapy. Although the movements resemble those of tai chi, they do not flow smoothly from one to another, but consist of short sequences of movements that are repeated many times. Qi Gong has been studied in China for its impact on arthritis and cancer, and for general health maintenance.

Among conditions that reportedly benefit from Qi Gong are many health problems of elderly people, including high blood pressure, heart disease, ulcers, arthritis, and gastrointestinal ailments. The exercise also appears to help immune function. Studies on Qi Gong have suggested that many age-related changes can be affected through regular practice.

Included in the studies are: A twenty-year study in China by Wang, completed in 1993, reported benefits of lowered blood pressure. Patients using Qi Gong experienced a 50% decrease in death and illness from strokes.

Research in China by Sheng-han in 1994 indicated that Qi Gong was able to alter such physiological reactions as EEGs, EMGs, respiratory movement, heart rate, skin potential, skin temperature, sympathetic nerve function, stomach and intestinal function, and metabolic rate.

During a 1997 study by Dr. Wen-hsien Wu of the New Jersey Medical School, Qi Gong was helpful for patients with reflex sympathetic dystrophy, a debilitating disease of the autonomic nervous system that often resists medical intervention. For these patients, Qi Gong significantly reduced pain and anxiety.

In a hospital in Beijing, ninety-three patients with advanced cancer were treated with a combination of drugs and Qi Gong exercises, while a control group was treated with drugs alone. 81% of the Qi Gong group showed a dramatic improvement in strength, 63% in appetite, and 33% were free from diarrhea, compared to improvements of 10%, 10%, and 6%, respectively, in the other group.

Our bodies are naturally designed for work. At one time our survival depended both on an ability to escape from danger and a capacity for hard work. Physical conditioning was the natural result of such a life. But modern conveniences have dramatically changed the way we use our bodies. Instead of working in the fields or chasing down dinner, many of us spend all day at a desk and our evenings in front of a television set.

Elevators and escalators have replaced staircases and vacuum cleaners have replaced rug beating. The automobile has become so much a part of our lives that in some areas anyone seen walking on the sidewalk is viewed with suspicion. So if our daily routine does not provide the necessary movement to keep us fit, we owe it to ourselves to find another alternative.

Using our bodies as they were meant to be used is an essential part of living a healthy and balanced life. Along with a proper diet, regular exercise helps prevent many diseases, lengthens life span, and improves the overall quality of life.

Our risk of developing one of the "illnesses of modern civilization" can be decreased by regular exercise. For some time now it has been known that exercising can reduce blood pressure, lower cholesterol levels, improve the ratio of lean muscle to fat, and strengthen and increase the heart's efficiency. All of these effects decrease the chance of death due to cardiovascular disease. More recently, scientists have noted a possible connection between certain types of cancer and inactivity. And finally, regular exercise combined with a sensible diet is still the most effective way in combating obesity.

Women benefit from regular exercise in another important way - exercise reduces the risk of osteoporosis by increasing bone formation and delaying bone loss. For women who already have the condition, exercise can help stop the progression of the disease. And because regular exercise reduces glucose-stimulated insulin secretion, it is helpful in controlling diabetes as well as in reducing the risk of adult-onset diabetes. Exercise also stimulates the secretion of other kinds of hormones that have been linked to decreases in clinical symptoms of anxiety and depression.

In addition, by improving circulation and nourishing tissues, exercise increases the range of movement of body joints, reduces the effects of stress and tension, and decreases or even cures insomnia. Of course there is some risk of injury with any kind of exercise. But the improved strength, balance, and coordination that comes from regular exercise greatly reduces the risk of all kinds of injuries.

Many activities can improve physical fitness, but some may be more suitable for you than others. A well-rounded fitness program should incorporate three basic components: cardiovascular endurance, muscular strength, and flexibility. Following this guideline, any program you select should include exercises that increase heart and lung capacity, stretch tight muscle groups and strengthen weak ones.

Cardiorespiratory fitness refers to how well the lungs deliver oxygen to the blood and how well the heart and circulatory system send blood and its nutrients throughout the body.
Programs that develop heart and lung capacity are often referred to as being aerobic, and they accomplish their goal by elevating the heart rate for a sustained period.
Aerobic exercise typically serves as the foundation for any fitness program since a healthy heart and lungs are essential to the safe and skillful performance of almost all activities and sports.

Depending on your level of fitness and what you hope to achieve, most experts recommend a minimum of 20 minutes of aerobic exercise three to five days a week. You may choose any activity that uses large muscle groups that can be maintained continuously and that is cardiorespiratory in nature. Examples include brisk walking, swimming, sprinting, bicycling, cross-country skiing, skating, stair-climbing, hiking, dancing, basketball, and soccer.

Intensity, or the speed of the workout, is crucial and is measured by how fast the heart is made to beat. Usually the goal is to reach 65% to 90% of the exerciser's highest possible heart rate and sustain this rate for some length of time.

Muscular strength and endurance exercises use progressive resistance to increase the size and strength of muscle fibers, resulting in a greater physical ability to perform work. Free weights are typical examples of the types of resistance equipment used in building strength. Push-ups, chin-ups, and curls produce similar results, but require no special equipment since they utilize the body's own weight as the source of resistance.

Despite popular conceptions, strength and endurance training is not just for weight lifters, boxers, and body-builders, but is an effective way of improving general fitness, converting fat to muscle, and increasing metabolic rate.

Stretching is an aspect of fitness that is often neglected. Many people choose activities that focus on strength and cardiorespiratory fitness but little in support of flexibility. However, most physical fitness professionals consider it an important element in achieving top physical performance. Some people are naturally less limber than others; to avoid strain or injury, the safest flexibility exercise is a slow, sustained stretch.

Flexibility training is all about increasing the range of motion around a joint. Many things determine a joint's flexibility, including the structure of the joint and the resilience of the attached muscles and connective tissue. As muscles become stronger through exercise, they also become tighter. That is, unless flexibility training is done. On this basis, gentle stretching may reduce the tightening effect of strength training and other endurance activities, as well as reduce the risk of injury.

Vitamin C: Vitamin C is the best known and most widely used nutritional supplement. Vitamin C supports the healing process in various types of conditions. However, it is important not to neglect fruit and vegetables when taking vitamin C. There is probably no upper limit to a safe dosage of vitamin C except for people who have hemochromatosis. But most people will experience diarrhea or nausea when taking more than 5,000 milligrams a day. With relatively few exceptions, 2,000 milligrams a day is enough vitamin C to influence the healing process.

Take vitamin C with caution if you take certain prescription drugs. Vitamin C taken in the form of vitamin C with bioflavonoids can interfere with the liver's ability to process statin drugs for controlling cholesterol. Rose hip vitamin C should not be taken by people with any allergy or sensitivity to rose hips.

Vitamin C is most effective in an alkaline environment. Diets high in carbohydrates and refined sugars produce acidity, so if you are going to take vitamin C, you will get the best results if you also restrict sugars and refined carbohydrates in your diet.

Vitamin D: Vitamin D is a group of chemicals synthesized in the skin from cholesterol with the help of sunlight, and also found in food. Deficiencies of vitamin D can result from failure to get enough sun. Mild vitamin D deficiencies are common in active elderly persons who avoid the sun because of concerns about wrinkles or skin cancer.

Severe vitamin D deficiencies are common among persons confined to nursing homes. Mild vitamin D deficiency can also result from being overweight. Subcutaneous fat absorbs the vitamin D made by the skin and keeps it from entering circulation. Vitamin D increases calcium absorption and strengthens bone. Vitamin D supplements are important for people who have diseases of absorption, such as cystic fibrosis, and pancreatitis.

Activated vitamin D is often helpful when prostate cancer has spread to the bones, as it reduces bone pain and prevents fractures. However, it can interfere with prescription medications for the condition and should only be used under the supervision of a physician.

Whether the bacterium that causes Lyme disease is trapped or escapes, causing an infection, after the skin is broken by a tick bite depends in part on whether the skin has an adequate supply of vitamin D. Skin cells that have an adequate supply of vitamin D are better able to secrete an immune hormone known as interleukin-8 (IL-8), which signals to white blood cells that a bacterium has invaded the skin. Vitamin D continues to be important in fighting Lyme disease as the infection spreads beyond the skin, enabling cells in other tissues to send out an alarm to the immune system.

For most conditions, vitamin D is dosed at 400-1,000 ID per day, although treatment of fractures sometimes requires 2,000 ID per day or even more for a short time.

Vitamin E: Vitamin E refers to a group of antioxidants known as tocopherols. Low levels of vitamin E are associated with an increased risk of cardiovascular disease, and supplemental vitamin E is used to stop inflammatory processes contributing to dozens of diseases and conditions. Effective daily doses of vitamin E range from 100 to1,000 IU per day.

Vitamin E should not be taken at the same time as iron supplements, since iron can oxidize and deactivate the vitamin. Any fatty food or supplemental essential fatty acid taken at the same time as vitamin E increases absorption of the vitamin, and most medications used to lower cholesterol taken at the same time as vitamin E decreases absorption of the vitamin.

In combination with prescription blood thinners or aspirin, vitamin E increases the risk of bleeding. Always tell your doctor that you are taking vitamin E if you are prescribed any blood-thinning medication. Since vitamin E reduces clotting factors in the blood, be sure to inform your doctor that you take vitamin E before any surgical procedure.

Vitamin K: Vitamin K is essential to the body's production of clotting factors and also to the formation of bone. Since vitamin K is dissolved in fats in food, supplemental vitamin K is essential in any condition impairing the body's ability to absorb fats, such as celiac disease, cystic fibrosis, or pancreatitis.

Supplemental vitamin K is also helpful in treating heavy periods and osteoporosis. Vitamin K is synthesized by bacteria in the intestine, so vitamin K levels go down during antibiotic treatment. However, taking vitamin K supplements as infrequently as every other week is usually sufficient.

A typical dosage of vitamin K is 5-10 milligrams, no more than twice a week except under medical advice. The Japanese soybean product natto is an excellent source of vitamin K for periods when vitamin tablets are not used. You should consider taking vitamin K supplements if you take more than 1,000 ID of vitamin E a day or if you take any medication for lowering cholesterol.

1. Do modern concrete structures present a hazard to our health? Some people notice traces of rheumatism and neuralgia after only a few weeks, or an increase in stiffness of the limbs or in the neck. Even depression may set in, although unknown before. If shortly after moving into a concrete structure, you notice these or other disturbances, you should experiment by spending a holiday with friends or relatives who live in a wooden or brick building. If your symptoms disappear while you are staying there, it would be reasonable in the interests of health to exchange the concrete structure, despite its modern conveniences, for a healthier dwelling place.

A humid home with little exposure to the sun can damage our health just as much as a concrete building. Pain and psychological suffering can be avoided if, in questions of where to live, we consider not only the cost but also the effect on our health. Living in a healthy home is of greater value than having modern conveniences.

2. Are We Watching Too Much Television? Television has intruded into our everyday life to such an extent that most people cannot imagine life without it. But what about its effects on our health? Cathode rays from the screen are really not harmless. They can damage our health in accord with our own susceptibility. However, rays particularly affect glands and the nervous system. You should therefore consider well whether a program is really worth seeing before you expose yourself to such damaging rays.

One should watch from a distance of about 12 to 18 feet. People subject to lymphatic trouble and those with poor nerves should expose themselves to the rays as little as possible. Watching television is particularly widespread among children, so little wonder that these show signs of striking ill-health. A very unfavorable effect on the nerves and mind has been noted. But instead of paying close attention to the symptoms and removing the cause, many doctors unfortunately disregard them, prescribing medicines to suppress the symptoms. Relief is expected from psychiatric drugs, but sadly in vain, because the harm done is too great to be completely removed.

Even youths are not always strong enough to get over such consequences, and nervous breakdowns have been reported. Parents should be more sensible and see to it that their children do not become addicted to television and exercise necessary control in supervising their viewing carefully.

Modern conveniences can make things easier but, on the other hand, they can put a greater strain on our nerves and minds. Let us select only worthwhile programs and use the rest of our time getting much required rest and relaxation.

Do not leave your television set running without thinking, for it is not good either mentally or health wise to soak in all these harmful things. Particularly in these times of stress, we should take care to get necessary rest, relaxation and quietness to help us recover and rally the forces needed to maintain a healthy mind and body. Though radio and television provide food for the mind, we should not thoughtlessly indulge.

The rays a television screen emits, especially from a color television set, are in no way harmless. Some of them are equal to X-rays. They can cause sensitive persons radiation damage to the skin similar to what is found in nurses working with X-rays. This could be mainly a chronic skin inflammation that does not easily heal. Remember that this can happen when we expose ourselves too long to rays coming from a television screen.
