The survey on nutritional health awareness among the adult population of hunan found that the population was better informed about “the right practice not to waste food”, “the identification of foods with more oil and salt”, “comparison of protein content in nutritional composition tables”, “methods for maintaining healthy weight”. At the same time, provincial cdc specialists have organized some of the nutritional health knowledge and misperceptions that exist among adult residents?
Knowledge panel 1: what are the common types of food to eat more? What do you want to eat? What's the recommended intake for salt sugar
According to the recommendations of the guide to food for the chinese population (2022), healthy adults should be able to eat more of their vegetables, vegetables, milk, whole valleys, soybeans, fish, poultry, eggs, and skinny meat at an appropriate level. On average, they should eat more than 12 foods per day and more than 25 foods per week。
Also, with regard to the recommended intake of saline sugar, we need to know that healthy adults should not eat more than 5 grams of salt per day, 25-30 grams of oil and, preferably, 25 grams of sugar. Does everyone remember? Only by getting the right scientific intake advice will we be better guided in our three meals
Knowledge panel 2: how does bmi calculate? How can bmi determine whether it is overweight or obese
Bmi is a commonly used indicator of health weight, calculated as bmi = weight (kg)÷
Height (m) x height (m)
The guide to food for chinese residents (2022) mentions that the bmi of our healthy adult population should remain between 18. 5 and 23. 9 kg/m2. Come to calculate their bmi according to the formula above and to see if their weight is in the normal range against the criteria below, as a better incentive to “eat balance” for themselves and their families。
Mistake 1: bones soup is the best source of calcium? Wrong
The calcium content in bone soup is low and is not easily absorbed, so it is not easy to drink bone soup for calcium. According to the guide to food for chinese residents (2022), the recommended source of calcium supplementation should be milk and its products, such as pure milk, yogurt and cheese, which are rich in calcium and easily absorbed by the body, and also contain high-quality proteins, which are nutritionally healthy choices, and it will be recalled that in the future no mistake will be made
Perception 2: spinach is iron-rich and easily absorbed? Wrong
Iron is one of the necessary trace elements of the human body and the most vulnerable to its scarcity. The spinach, which we often eat, contains more abundant iron, but which is non-hemoglobin iron, and which is not recommended for iron supplementation because its herbal acid affects its absorption. Animal foods such as animal liver, animal blood, animal meat and fish shrimp are a good source of iron。
