What food?

The food makes the body function, grow and repair. The type of food you eat can affect the efficiency of these processes. The function of the body and food that supports it is infinitely more complex. The food is indeed one of the most complex phrases imaginable chemicals.

Knowing the nutrients in foods can help you understand some of the complex relationship between your food and your body.

Chemicals in food

The food consists of many different chemicals-the macronutrients (main food ingredients present in relatively large amounts, such as proteins), trace elements (main food ingredients present in relatively small amounts, such as vitamins), water and fibers. Many other components can also be present in the diet (see Figure 1).

Food can contain colors (natural and synthetic), flavors, pharmacologically active substances (such as caffeine, steroids and salicylates that are chemically applied to the body), natural toxins (toxins of natural origin, such as cyanide); Impurities (substances resulting from a contaminated environment, such as pesticides). Also, the characteristic aromas such as orange and passion fruit may depend on the presence of a dozen or more chemicals.

The chemical nature of the feed is altered by the storage, preservation and in particular, by cooking. Chemicals that are present in foods can also interact with each other within the body. For example, the determination of the body of the iron from plant sources depends on the amount of vitamin C in foods that are eaten. How carbohydrates absorb from the intestine depends to a certain extent on the presence of dietary fibers, the fiber itself not being absorbed.

Fitness food

The food is also more than the chemicals it contains. Their physical properties are important. The size of the food particles can affect the extent to which the nutrients are digested and prepare themselves for the absorption by the body to learn more about this concept. For example, an intact apple has to eat another diet drink all the same chemicals in the apple sauce. Polished rice is digested faster than rice unbelted. The nutrients are easier to absorb peanut butter (pulp) ate whole peanuts.

Acid or alkaline

The acidity and alkalinity of foods are often the physical properties are important. In fact, they are only important to the extent that the rate of gastric emptying, digestion in the small intestine, and the acidity or alkalinity of the urine can change. Our bodies with a wide range of foods can deal with no big problems acidity Find more to this term and alkalinity. Acid foods are usually sour, while alkaline foods often have a slightly soapy taste. The use of sodium bicarbonate (baking soda) can be alkaline food. It can also cause loss of vitamin C and help our sodium intake.
