Although, in reality, the most important biological macronutrients, such as proteins, carbohydrates, and fats, can be found in many foods, the human diet must contain the healthiest and richest polymer-rich ingredients. For instance, there is no doubt that a burger or a hot dog can contain large amounts of carbohydrates and fats, but regular consumption of such meals negatively affects the cardiovascular and endocrine systems. The purpose of this post — to find the best food sources — is due to the necessity to consume enough proteins, fats, and carbohydrates.
Carbohydrates are present in almost all products in the form of sugars: glucose, fructose, and starch. These are vital molecules that determine the energy exchange within the body. Traditionally, the best carbohydrates sources, rich in slow and digestible carbohydrates, are fruits and vegetables: pumpkins, beet, apples, quinoa, and berries. The best cereals are oats, buckwheat, peas, and lentils. Meanwhile, it is incorrect to believe that fats are poor and bad components of the diet: useful fats are best found in nuts, avocados, vegetable oils, chicken eggs, and fatty fish like salmon and tuna. Such sources contain a large number of monounsaturated and polyunsaturated fatty acids, which are essential for the body. The most useful products rich in proteins are eggs, chicken meat, cottage cheese, wholemeal bread, and fish.
Although specific data on the average consumption of macronutrients vary, on average, an adult should receive about 45-65% of calories from carbohydrates, 10-30% from proteins, and 20-35% from fats. Complying with this norm, a person guarantees themselves a complete diet. Thus, it seems that this is quite the real percentage for a person who is responsible for nutrition. Such figures mean that a person should eat all the above products in sufficient quantities every day: it is not exotic food, but available at the supermarket. However, it should be recognized that most people do not care much about the quality of the food they eat and replace healthy ingredients with fast food, semi-finished and fatty foods. In this case, an elementary preponderance of carbohydrates or fats is created, and the body does not get enough of all nutrients.
