What is food?

Food is a substance that produces energy in the body of organisms and causes growth and ultimately life. Choosing the right food, whether solid or liquid, promotes the health of body parts, hair, nails, skin, cells, and tissues, and the choice we make creates deadly diseases and problems for us.

For a long time when science was not yet advanced, eating and nutrition were considered only as a task and filling the stomach, but over time and the beginning of modern life, the model of nutrition changed and took a scientific form.

Food as a whole consists of different parts

  • Proteins
  • Carbohydrates or starches
  • Fats and dairy products
  • Vitamins
  • Minerals
  • Sugars
  • Proteins

 Includes red meat, chicken, fish, legumes, and eggs. Protein intake should be done daily and regularly because proteins are not stored in the body and must be provided constantly.

A protein-rich diet lowers the hormone cortisol and reduces stress and prevents overeating. Protein also helps build bones, limbs, and muscles, and regulates hormones. At the same time, excessive consumption of protein can cause cancer.

Carbohydrates

There are two types: starchy and non-starchy

Starch’s are like rice, bread, and pasta that make us feel full immediately after eating and raise blood sugar. This type of carbohydrate, which is usually recommended to athletes after exercise or in the morning, builds muscle and strengthens the body. And provide energy to the body. Non-starches such as whole grains, which are whole grains, and fruits, which are high in fiber and gradually raise blood sugar, provide longer-term satiety.

Some foods that are high in carbohydrates include apples, oranges, grapefruits, blueberries, beets, sweet potatoes, oats, and bananas.

Fats

There are two categories of fats: saturated (unhealthy) and unsaturated (healthy).

Solid saturated fats such as butter and cheese and concentrated high-fat milk and foods made from these ingredients such as cakes and biscuits and sweets, chips and puffs as well as red meat fats and chicken skin. Consumption of saturated fats is very harmful to the heart Are. When shopping, be sure to read the labels on the goods to make a more informed purchase.

Unsaturated are usually liquid and are mostly sourced from plant sources and are less dangerous to the body, such as olive oil, sunflower, sesame, and soy. Unsaturated fats in olives significantly reduce heart disease and cancer.

For health, it is better to avoid high-fat and fried foods and replace grilled and steamed foods and low-fat dairy products, but at the same time avoid complete fat removal, which is necessary for the body in small amounts.

Vitamins

Vitamins are an essential part of your daily diet. Vitamins are very diverse and have special functions for different parts of the body and their health. Vitamins are very diverse and their types can be named A, B, C, K, D, and E.

To speed up cell repair, vitamins are usually strongly recommended to the patient after major surgeries such as open-heart surgery, liposuction, delivery, etc. to accelerate his recovery process. Keep in mind that taking large amounts of vitamins is not only useless but also harmful and leaves irreversible side effects. Therefore, it is better to consult a specialist to consume the right amount.

Calcium is one of the most important and is abundant in milk and yogurt and dairy products in general and should be for the health and strength of bones and teeth and proper functioning. Nerves and muscles should be used, especially in childhood and up to the age of 35. If we are deprived of enough calcium at this age, we will face severe osteoporosis at an older age, which is one of the most terrible diseases of the present century and destroys and destroys human beings.

It is even recommended that people who are allergic to calcium and cannot digest it use substitutes such as soy milk or spinach and cabbage, almonds, and dates.

Today, some people think that high-fat milk and yogurt have more calcium, but it should be said that there is no difference between the amount of calcium in low-fat and high-fat dairy products, and it is better to use low-fat dairy products only for fat.

Iodine deficiency causes thyroid problems. Phosphorus is essential for cellular function. Chromium controls blood sugar levels. Potassium helps regulate blood pressure and magnesium helps with heart rhythm and muscle and nerve function.

Lack of other materials Minerals can cause physical problems, fatigue, lethargy, and bone weakness. And these are just a few examples to show the importance of minerals.
