Some diseases result primarily from nutritional diseases - the major deficiency diseases and obesity.
Deficiency diseases seldom present in pure form. More often than not they are secondary to some other illness. Even where food is short, not all the members of a community are equally affected. Individuals with with some physical or mental abnormality usually show clinical menifestation first. Young children and disabled adults are the most vulnerable.
When malnutrition occurs it is unlikely to involve only one nutrient. Even if the clinical features suggest a single deficiency, biochemical tests usually reveal depletion of other nutrients. Treatment should therefore not be confined to large intakes of the nutrient whose deficiency is indicated by the clinical signs. Furthermore, malnourished patients are liable to complications, especially certain infections which may be the presenting illness or may occur in modified form because malnutrition has supressed some of their characteristic signs. Thus complications of malnutrition must be looked for and treated. Much of the skill in diagnosing patients with malnutrition is being aware of and dientangling predisposing illness, other associated malnutrition and complicating diseases.

Oats are high in protein and oil compared to other grains. The distribution of fat in oat groats is different from other cereal grains in that the endosperm is relatively much higher in fat. Oats contain enzyme systems com
mon to other cereal grain such as amylases, lipases, esterases and proteinases. However, oats have been shown to exhibit relatively high lipase and proteinase activity, compared to other grains. Because oat endosperm carries apprecialble portions of fat, lipolytic activity of rolled oats as a food is of paramount importance. When groats are properly dried and steamed the flakes will remain low in free fatty acids for long period of time. This stability has been attributed to the inactivation of lipases during the drying and steaming process prior to rolling the flakes.
Rolled Oats in The Diet
Rolled oats is essentially a whole grained product and has a higher crude protein content than other cereal foods. Only the hull is removed and the germ fraction containing protein of superior nutritional quality is not lost. This fact helps explain the superior growth promoting value of protein in rolled oats compared to other cereal products. The results of growth tests using weanling rats indicate no significant difference in quality between proteins of groats and rolled oats made from them.

Doctors use several equations to calculate how many calories a person should eat each day to maintain a stable weight. The most precise ones include height, weight, age, sex, activity level, and stressors like an injury or disease. The simplest way to estimate your daily target for calories is to multiply your weights in pounds by :-
- 12 if you are sedentary (little or no exercise)
- 13.5 if you are somewhat active (light exercise one to three days a week)
- 15.5 if you are moderately active (moderate exercise like brisk walking - you break into sweat - three to five days a week)
- 17 if you are highly active (vigorous exercise or sports six to seven days a week)
- 19 if you are highly active (daily vigorous exercise or sports and a physical job)
For example, a somewhat active person who weighs 45 pounds (66 Kg) needs about 1950 calories a day (145 times 13.5) to keep a steady weight.
To lose weight, start by reducing your intake by 250 calories per day. That’s one can of cola and two butter cookies, or 50 gms of potato chips. If you keep that up for a year, you could shed 20 pounds. Add in more exercise, and you could make it 30 pounds.

If you indulge into high-fat foods occasionally you may be able to avoid weight gain by staying active. A recent study from the University of Wisconsin in Madison found that regular exercise helps the body fire up metabolism more quickly to adjust for an increase in fat intake.
The researchers assigned a group of 10 sedentary women to exercise at two different intensity levels as they switched from a low-fat diet (with 30 percent of calories from fat) to a high fat diet (50 percent of calories from fat). The team then compared the volunteers’ ability to burn calories when the women were sedentary when they burned up 150 calories during an hour on a stationary bicycle, or when they burned 300 calories on the exercise bike over a two-hour period. The more each woman exercised, the faster she was able to burn fat calories after switching to a four-day high fat diet. The team reported in the American Journal of Clinical Nutrition.
It’s not clear why exercise helped the women burn more fat calories. Dietary fat is often stored in fatty tissue, rather than sent to muscle tissue where it is used for energy. Working out may have helped shift dietary fat toward more metabolically active tissues, like muscle, and could have increased the activity of fat-burning enzymes in muscles, the researchers speculate. So another good reason to get a move on and control one’s own health destiny and at the same time enjoy the taste of favorite dishes which many avoid in order to look good.
