        In the case of Mr. Tanaka, there are some problems in his daily diet and lifestyle habit, but they can be solved by focusing his attention and effort. Also one problem exists in his family history of disease.

        In his diet, there are so many points he should change. First he seldom eats breakfast. Skipping meals can lead to out-of-control hunger, often resulting in overeating. When a man is very hungry, it's also tempting to forget about good nutrition. And he doesn't take recommended daily amounts (RDA) of vitamins and minerals also enough fibers, and likes LDL rich foods. For example, he likes red meat, and dislikes vegetables. He usually eats fast food such as hamburgers or udon. That is not only because he is busy with his business and doesn't has enough time for taking his meal, but also because he tastes them. These food are containing less vitamins and minerals or fibers. Though Mr.Tanaka knows he can't take enough vitamins from his daily diet so he takes vitamin supplements, considering other his diet and lifestyle habit, it might be not proper to the RDA for his age. For example he should take 2,000IU of vitamin A, 1.1mg of vitamin B1, 1.4mg of vitamin B2, 50mg of vitamin C, 100IU of vitamin D, 12mg of iron, 25 to 30 grams of fiber and so on. And he should limits the fats under 10% of whole calories he needs in a day. Because fats, especially saturated fats tend to raise the cholesterol level in the blood. And the high level of cholesterol in the blood is thought as a risk factor of some cardiovascular disease ( This point is mentioned further below.) . Carbohydrates and fats are main source of energy of human but carbohydrates don't have an explicit effect to raise the LDL level of the blood. So the most calories should be taken as carbohydrates. In addition, yet there are some places or systems in a human body which can't function properly without fats (for example, the cell's membrane, in the time of intaking or transporting fat-soluble vitamins, etc.), human can synthesize fats by carbohydrates in the liver. Also total calories should be limited because taking too many calories may cause diabetes. As he is a desk-worker, the RDA of calories for his age is 2,200 to 2,400.

        His lifestyle habit problems are that he doesn't exercise (he does only a half an hour on a week). So he can't easily work off the calories he's consumed, and this can cause such diseases as diabetes or high blood pressure and so on. Mr.Tanaka does exercise only because he thinks young should keep his weight down. That is he doesn't know the effectiveness of exercise for the health. Exercise has effects not only on energy consumption but also in activating the metabolism (such as replacing the old cell to the new cell, excretion, etc.).

        In his family history, there is a tendency to have diabetes or heart disease. This character is probably inherited by him too, so he should be more careful about his health from this point than other people.

        In conclusion, he has to do the following. First, he should take regular meals every day. Second, he should take RDA of vitamins and minerals (mentioned above) in a variety of foods, when it's impossible taking them from foods, although supplements will help. But either way, it is important to take his RDA of vitamins and minerals. Third, he should take much more fiber. Fiber helps bowel movement and removes t bad materials such as bad cholesterol. Fourth, he should eat less amounts of LDL-rich foods. He likes red meat or cheeseburgers, and those are LDL-rich foods. And now his LDL level is 172. This is too high for health (for his age, the level should be less than 130). Still his family history suggests he has possibillities to have diabetes or heart disease, and these are often brought on by a high LDL level. So he has to change his diet to reduce high-LDL containing foods. Concerning the last point, he should take regular exercise every day. Exercise can speed the metabolism, consume excess calories, increase HDL (which has a role in reducing LDL). Keeping these ideas outlined here, he will achieve a healthy weight and a low LDL level. But I should add one more piece of advice: he should check his LDL level in his blood and cardiovascular system in the hospital regularly.
