What Is Healthy Diet?

Is there such thing as healthy diet? Depends on a definition. If the word 'diet' is used to define any way of eating, there of course can be such thing as healthy diet. However, we usually mean that dieting is eliminating some foods or food groups from our menus or limiting calories in order to lose weight. As it comes to calorie restriction, there's scientific evidence that such a measure can prolong life and hinder the process of aging. This effect is more prominent when the diet is started earlier in life but recent research showed that even after the age of 65, restricting calorie intake by 25% reduced the risk of Altzheimer's disease. Biological markers (some specific proteins in body's tissues) that dieters seemed to appear longer their calendar age. Eliminating some food groups can be beneficial or not depending on foods. Nobody benefits from refined carbohydrates and cutting down on them showed improvement in important health characteristics including insulin sensitivity, "good" cholesterol levels, and blood pressure. Eliminating fats is altogether another thing. Even saturated animal fats are not nearly as bad for you as dietitians used to warn us, leave alone unsaturated plant and fish fats. The bottom line is, the current diet trend is to make it sure that we have enough of good foods on the plate. It's important to remember that when we reduce calories, we automatically reduce essential nutrients.
