Proper nutrition has become essential in modern life, at all ages, even for children. Obviously, in order to be correct, the diet must take into account all the nutritional principles and be based on a great variety of foods: vegetables, cereals, vegetables, eggs, meat, pasta, sweets, fruit etc …; but, at the same time, it must provide an adequate number of calories, neither higher nor lower than the energy requirement, which naturally differs from subject to subject, according to age, sex, body weight and the type of activity that takes place .
When nutrition is lacking, diseases or in any case imbalances in the body can occur, because each food has its own function: carbohydrates have an energy function, proteins act as plastic substances, fats are used for the production of calories and energy , vitamins instead serve to regulate and protect our body. The lack of a single vitamin is enough to cause damage to our body, and when this happens, unfortunately, it becomes rather complex to restore the optimal condition.
On the other hand, when there is a caloric excess, the so-called pancetta is formed, and if you overdo it you can even become obese; but apart from the purely aesthetic problem, health is in grave danger.
A large number of heart attacks is in fact caused by a too high percentage of fat in the blood; not to mention the physical form, which naturally goes below zero. When there is a shortage of calories, there is a lack of energy and the body has to cope with it by drawing from the reserves of fat, without which organic wasting can occur with enormous damage. However, the food problem varies according to the areas of the world. While in industrialized countries there is a problem of abundance, therefore of overweight, in Third World countries there is too little food and of too poor quality to allow proper nutrition. The latter situation is evidently the most serious, given that thousands of people die from malnutrition, especially children, as often shown on television while we eat our hearty meals. Currently, hunger kills at the staggering rate of 20,000 people a day in underdeveloped countries; but what is most frightening is that this problem is practically unsolvable. Western countries should give these people more lasting and concrete help, trying not to take advantage of their economic condition to make money. Here, the problem is reversed; there is too much abundance, we gain too much weight and then we have trouble getting the kilos off us. In America, for example, astronomical amounts are spent every year on diets, which are necessary for a correct line.
The worst way to lose weight is to use tablets that reduce hunger, which, in addition to hurting the body, are not very suitable for achieving the goal. The most rational thing is to face a diet that is not too violent, but protracted over time. A system that seems to work well is this: two weeks of a not particularly rigid diet, interspersed with another three of controlled diet, without excess. Of course, this is not enough if one does not engage in sports with a certain frequency, which in turn, alone, would not be able to cancel substantial caloric excesses. Dedicating yourself to sport with a certain passion is an excellent method to stay in constant shape, not only for the effectiveness in itself of physical activity, which burns calories, but because it forces you not to get too heavy at the table, especially if you have shrewdness to plan the course of their training sessions immediately after meals. For the less athletic, if you want to keep fit, you need to calculate the calories in and out. So, if in addition to the normal meal you eat a dessert, when you just can’t do without it, you need to do additional physical activity that balances the budget.
In order to significantly improve the food culture in our country, it would be desirable to include one hour of weekly education in school programs. However, it should not be a further subject of study, which would probably end up increasing students’ hatred of school, but a pleasant and constructive contribution.
