Every living thing on earth needs food that can sustain life and give strength. Man is no exception, he is also completely dependent on food. It would seem that everything is simple here: you just need to throw more fuel into the “oven” so that the body feels he althy and full. But, as it turned out, the selection of proper nutrition is a whole science with its own rules and laws.

Food for pleasure

Food is needed in order to live, not vice versa. However, today people often consume many times more food than they need. Fast food and confectionery shops invite more and more hordes of "hamsters" obediently gnawing junk food of dubious origin. A modern person eats everywhere - while driving, at the TV, on the way home, during leisure and during working hours. Nutrition has become the worst weapon of degradation, leaving behind such masters of this business as drugs and television.

The result of the thoughtless consumption of harmful food has become numerous diseases,which today are considered "normal" for city dwellers. These are pathologies of the gastrointestinal tract, cardiovascular system, as well as oncology. It is stupid and irrational nutrition that is their cause. To get rid of this harmful trend, scientists and nutritionists are constantly developing and offering more and more new schemes and types of nutrition. Which? Read more about this

Rational nutrition

Bright minds have long come up with a system that allows you to use food as efficiently as possible. It is called rational nutrition and involves compiling a diet taking into account age, gender, lifestyle, he alth status and climate. The basic principles of this system are simple and logical, but few dare to change their way of life. Naturally, the same diet cannot suit everyone, so the easiest way is to familiarize yourself with the basic principles in order to then independently create a suitable menu.

What will the transition to a balanced diet give? He alth and longevity, cheerfulness, clarity of thought and good mood. Like many other types of nutrition, rational is designed to normalize the functioning of the digestive system. As a result, useful substances from food are absorbed as efficiently as possible, excess weight is lost, and resistance to diseases is increased.

Principles of good nutrition

The balance between energy expended and received is a very important component of a he althy diet. Our body spends energy on the work of muscles and internal organs, thought processes, maintaining body temperature andother pleasant little things, without which our life would be impossible. If there is not enough energy supplied, it begins to be withdrawn from fatty tissues and muscles, gradually depleting the body and rendering it unusable. Since food is the main source of energy, there should be enough of it to cover all our costs. Excessive food intake is no less harmful than its lack, because in this case the body stores the excess in the form of fat. Obesity, in turn, contributes to the emergence of many diseases, and generally brings a lot of inconvenience to its victim.

It is important to maintain a balance between nutrients in order to get the most beneficial effect from food. It is believed that the optimal ratio of proteins, fats and carbohydrates for an adult is 1:1:4. If he goes in for sports or hard physical labor, then the ratio changes to 1:1:5. In addition, you need to follow the regime. Different types of catering offer their options, but much depends on the he alth of the person. Rational nutrition involves four meals a day, which helps to saturate the body and eliminates the feeling of hunger. It is advisable to start a meal at the same time, have dinner at least 2-3 hours before bedtime.

He alth food

When a person is sick, ordinary food can aggravate his condition. Therefore, doctors have developed a therapeutic diet that contributes to the speedy recovery of the patient. Its impact cannot be point-wise - an integrated approach is needed. So, those are selectedtypes of food that will have a medicinal effect on the entire human body. At the same time, at different stages of the disease, the diet can be very different. In some cases, low-calorie foods are recommended in minimal amounts, but this may not last long.

Healing nutrition largely depends on the disease and condition of the patient. It is necessary to exclude heavy and harmful foods so that the patient spends energy on fighting the disease, and not on food. In some kidney diseases, it is necessary to reduce the amount of protein consumed, but its level cannot be lower than the minimum required. Often the right food is the cure in itself, if the disease has not had time to develop.

Separate meals

Listing the main types of nutrition, it is worth mentioning an interesting system developed by Herbert Shelton. It is called separate nutrition and is based on the fact that different foods require different enzymes. Shelton argues that the simplest food is the key to good he alth, and some food combinations are generally dangerous for humans. A mixture of proteins and carbohydrates is especially harmful, since completely different enzymes are needed to break them down.

Protein requires an acidic environment for digestion, while carbohydrates require an alkaline environment. Many modern types of nutrition do not take into account this fact, and after all, when acid and alkali interact, neutralization occurs. As a result, food floats in the stomach for long hours instead of being digested in it. separatenutrition recommends eating fruit only as a separate dish and always on an empty stomach. Dairy products should also be consumed separately, as they interfere with the absorption of other foods. Separate nutrition brings tangible benefits, as the energy that used to go into the fight against incompatible products is now completely at your disposal.

Smarter approach

Schemes involving different types of food often use the same principles. It is not at all necessary to study the works of scientists and physicians in order to understand what you need. It is better to listen to your body than other people's thoughts. After eating, you should be charged with energy, and not lie like a corpse on the couch, feeling powerless and drowsy. Eating is a procedure that keeps us alive, not a hobby to which we can devote all our free time.

Food establishments of all kinds, such as restaurants, cafes and eateries, create beautiful and tasty dishes, but their he alth benefits are very questionable. The best food is homemade, made from fresh and quality ingredients. Instead of mindlessly devouring sweets, try to make a competent and balanced diet. The results of this bold move will exceed all your expectations!
