In our daily lives, we need to obtain more than fifty nutrients from food. These nutrients are roughly divided into six categories: protein, carbohydrates, lipids, vitamins, minerals, and water. Only through a reasonable diet Only in this way can we meet the needs of our body. If we eat unreasonably, it will not be good for our health, and we will often get sick.

So, how can we eat scientifically?

1. Our daily diet must comply with the requirements of the "pyramid diet model". Pyramid eating pattern: refers to the amount of various types of food eaten every day (or a diet cycle), vividly compared to the proportion of the total volume of the "pyramid". That is to say, the food at the bottom of the dietary pyramid: water, has the greatest demand; followed by: grains, rice, and pasta, with the next highest proportion; the food in the middle of the pyramid: vegetables and fruits, with the third highest proportion; and the food in the middle of the pyramid is higher. Foods such as milk, eggs, fish, and beans have smaller dietary requirements; the food at the top of the pyramid: fat, accounts for the smallest proportion. Therefore, this tells us that we should not be partial to a particular diet, but should eat reasonably according to the needs of the body and the proportions of various types of food in the "pyramid eating model".

2. The diet should be diverse. Metaphorically speaking, the types of vegetables and foods should be diversified, because each food contains different nutrients. In order to meet the body's needs for various nutrients, food diversification is the best way to eat.

Of course, in some areas, food or water is deficient in iodine. A good way in our country is to add iodine to table salt, which can prevent big neck disease caused by iodine deficiency.
