        It is good that Mr. Tanaka is thinking about his health. And it is good that he is reading many different magazines and Internet sites to study the health condition. I think he is far from good health, however. He has some problems for his health. It seems that he doesn't understand all this information correctly and can't make use of the information. So I want to suggest the following to help him.

        First, I must answer his question about RDA of vitamins and minerals. Although we must get much nutrition, he is short of nutrition. Because he is very confused about what would be the recommended daily amounts (RDA) of vitamins and minerals for a man his age, I must say about them. Vitamins and minerals need for human. We don't live without them. Vitamins help the body turn food into energy and tissues. There are 13 vitamins in all: vitamin A (750ug); the vitamin B complex, which includes thiamin (1.2mg), riboflavin (1.8mg), niacin (20mg), vitamin B6, folic acid (200ug), vitamin B12 pantothenic acid (2ug), and biotin; and vitamins C (30mg), D (2.5ug), E (10ug), and K (140ug). (The man who is 65kg needs par days.) Minerals are needed for growth and maintenance of body structures. Plants and animals do not make minerals. Animals get minerals by eating plants or plant-eating animals. The minerals the body needs in large amounts include calcium (800mg), chlorine, magnesium (350mg), phosphorus (800mg), potassium, sodium, and sulfur. Other minerals, called trace elements, are needed in much smaller amounts. Trace elements include iron (10mg), copper, fluorine, iodine (150ug), selenium, zinc (15mg), chromium, cobalt, manganese, and molybdenum. (The man who is 65kg needs par days.) Next I must say about the real difference between carbohydrates and fat. Carbohydrates and fats are the primary energy sources for body. Carbohydrates include all starches and sugars. They are the body's main source of energy. Each gram of carbohydrate provides 4 calories. And most foods contain carbohydrates. For example foods such as beans, breads, cereals, pasta, and potatoes contain carbohydrates. But fats pack a lot of energy. Each gram of fat provides 9 calories. Especially saturated fat is often called "bad" fat. Saturated fats include animal and dairy fats, which remain solid at room temperature. Protein is important for man. Proteins provide energy at 4 calories per gram, but they are more important as the body's building materials. Meat, poultry, fish, dairy products, eggs, cereals, legumes, and nuts are all good sources of protein. However high revel protein food cause several diseases. So it isn't good enough that he pay attention to eating red meat which has lots of high protein.

        Second, I must talk about his eating style. It is unfortunate that he says he is busy six and sometimes seven days a week, and he does not have time to eat breakfast most mornings. And he takes fast food like hamburgers, cheeseburgers, or udon at lunch and dinner. Also he relies on vitamin supplements which he takes with four or five cups of coffee in the morning and colas in the afternoon. And he really hates most vegetables; on the other hand, he takes a lot of meat, beef and pork mostly. Though first he should eat three times par day. Breakfast is most important a day. Because breakfast supply lots of energy we need for work. Second he shouldn't eat such food, but he should eat vegetables in spite of his liking. Because fast food is not balanced food, he can not take enough nutrition like vitamins, minerals and fibers. That kind of foods has much fat, cholesterol and salt. Fat, cholesterol and salt can cause many diseases. About these disease I say after. Third he relies on vitamin supplements, so he had better take vitamins from vegetables. Meet, beef and pork include some nutrition like protein, magnesium, iron, phosphorus, selenium and zinc. But if he takes too many meets, his cholesterol level will become high. Forth fiber is also important for the body. Fiber helps reduce the rates of cancer. And fiber appears to have the ability to lower cholesterol levels in the blood. A number of foods are good sources of fiber, including fruits, vegetables, legumes, nuts, and whole grains. Certainly he says that he gets fibers from eating udon and rice. But thinking on the point of whole balance, he should take it from more variety foods. We get little fiber from udon and rice. There are two kinds of fiber, soluble and insoluble. Fifth he often drink coffee. It is serious problem. Coffee has too much caffeine. Caffeine is a drug, which stimulates the central nervous system. Caffeine supply water to the body initially, contain diuretics that cause the body to lose the water. Water just may be the most important nutrient because our body is more than half water. And coffee destroy Ca. Ca is a kind of the mineral. It is important for us to make bone and tooth. Colas reduce Ca, too.

        Third, I must say something about his exercise and his stress. Certainly it is good for him to run to keep his weight down, but that is not all. Even if he is busy, it is too short a time when he exercises for only about a half an hour once a week. In spite of our age, we need to exercise more and more; and if we do, we are more and more healthy. So he should exercise more. Stress also affects his cholesterol level. He has been feeling lots of pressure at work lately, and most recently he finds it hard to relax even after work. It is OK even if the time when he can relax is short. Doing relaxation exercises is important.

        Lastly, I must discuss his high LDL level. Low-density lipoprotein (LDL) cholesterol is bad. High levels of LDL in the bloodstream are associated with an increased risk of heart disease. His LDL level is measured at 172. It' high -- a normal LDL cholesterol level of less than 130 is best. A LDL level of 160 or higher means you have an increased risk for heart disease. Cholesterol is necessary to the cells and helps the body make hormones, but too much cholesterol in the blood can make its way to the arteries, where it stays in the form of a thick, fatty substance called plaque. The buildup of plaque narrows the arteries and makes it increasingly difficult for blood to make its way through them. This creates a condition called atherosclerosis. There may be no signs or symptoms of atherosclerosis until a heart attack or stroke occurs. The lower his LDL cholesterol levels, the better off he is. So he control the amount of his cholesterol in his bloodstream. And he has heredity of diabetes. What is the worse, he doesn't have correct knowledge about cholesterol. Increase of cholesterol doesn't only depend on eating sweats foods. The amount of cholesterol in bloodstream depends on heredity, diet, and lifestyle. What should he do? He should adjust his diet. So he must acquire correct knowledge about it, and control it. And he reduces the saturated fat. Saturated fat affects his cholesterol level; in fact, it's a worse offender. Keep his saturated fat intake under 10 percent of his calories each day, and he is on his way to lower cholesterol levels. These foods which contain saturated fat indicate before.

        Mr. Tanaka should think about his health more deeply. And he should change his lifestyle. First he should take a rest as much as possible. Second he should eat good healthy food and well-balanced food which has many vitamins and minerals. Third he should exercise more. Last he should pay attention to his health. So he will be healthy.
