Types of human nutrition, nutrition

All living things on earth need food that can support life and give strength. Man is no exception, he is also completely dependent on food. It would seem that everything is simple: you just need to throw more fuel into the "stove," so that the body feels healthy and well-fed. But, as it turned out, choosing the right food is a whole science with its own rules and laws.

Meals for fun

Food is needed in order to live, not vice versa. However, today people often consume a lot more food than they need. Fastfoods and confectionery shops are beckoning more and more hordes of "hamsters" obediently gnawing harmful food of dubious origin. The modern person eats everywhere - at the wheel, at the TV, on the way home, during the rest and during business hours. Nutrition has become a terrible weapon of degradation, leaving behind such masters of this case as drugs and television.

The result of thoughtless absorption of harmful food has become numerous diseases, which today are considered "normal" for urban residents. This pathology of the gastrointestinal tract, cardiovascular system, as well as oncology. It is a stupid and irrational food is their cause. To get rid of this harmful tendency, scientists and nutritionists constantly develop and offer all new and new schemes and types of nutrition. What kind? Read more about this

Balanced diet

Light 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 drawing up a diet that takes into account age, sex, lifestyle, health 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 can not be suitable for everyone, so it's easiest to get acquainted with the basic principles, then to independently create a suitable menu.

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

Principles of rational nutrition

The balance between spent and received energy is a very important component of a healthy diet. Our body spends energy on the work of muscles and internal organs, thought processes, maintaining body temperature and other pleasant trifles, without which our life would be impossible. If the energy is not enough, it starts to be withdrawn from the fat tissues and muscles, gradually depleting the body and disabling it. Since food is the main source of energy, they should be enough to cover all our costs. Excessive consumption of food is not less harmful than its lack, because in this case the body stores 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 balance the nutrients to get the most beneficial effect from eating. It is believed that the optimal ratio of proteins, fats and carbohydrates for an adult is 1: 1: 4. If he is engaged in sports or heavy physical labor, the ratio varies by 1: 1: 5. In addition, you need to comply with the regime. Different types of catering offer their options, but much depends on human health. Rational nutrition involves four meals a day, which contributes to the saturation of the body and relieves the feeling of hunger. It is advisable to start the meal at the same time, to have supper no less than 2-3 hours before bedtime.

Health food

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

Therapeutic diet depends largely on the illness and condition of the patient. It is necessary to exclude heavy and harmful products so that the patient spends energy on fighting the disease, not with food. With some kidney diseases, it is necessary to reduce the amount of protein consumed, but its level can not be lower than the minimum required. Often, the right food is itself a medicine if the disease does not have time to develop.

Separate food

Listing the main types of food, it is worth mentioning the interesting system developed by Herbert Shelton. It is called a separate diet and is based on the fact that different foods require different enzymes. Shelton argues that the simplest food is a guarantee of good health, and some combinations of products are generally dangerous to humans. Especially harmful is a mixture of proteins and carbohydrates, since for their cleavage, absolutely different enzymes are needed.

To assimilate protein food requires an acidic environment, and for carbohydrates - alkaline. Many modern types of nutrition do not take this fact into account, and after all, the interaction of acid and alkali is neutralized. As a result, food for long hours floats in the stomach instead of digesting in it. Separate food 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 assimilation of other foods. Separate food brings tangible benefits, since the energy that used to go to fight incompatible products is now completely at your disposal.

Reasonable approach

Diagrams in which different types of nutrition are involved often use the same principles. It is not necessary to study the works of scientists and doctors to understand what you need. It is better to listen to your body than other people's thoughts. After a meal, you must be charged with energy, and not lie on the couch on the couch, feeling impotent and sleepy. Eating is a procedure that supports life in us, and not a hobby that can be given all the free time.

All kinds of food companies, such as restaurants, cafes and eateries, create beautiful and tasty dishes, but their health benefits are very doubtful. The best food is homemade, prepared from fresh and quality products. Instead of thoughtless eating of delicious food, try to create a literate and balanced diet. The results of this courageous step will surpass all your expectations!
