In the process of food production and consumption (including processing and transportation), foods with low energy consumption and low emission of greenhouse gases such as carbon dioxide are called low-carbon foods, and vice versa.
Low-carbon food mainly refers to two aspects. One is the simplification of food packaging: in the past, the packaging of many leisure snacks was "three layers inside and three layers outside". For example, some "leisure gift packages", several packs of snacks are packaged in large packages, and two are packaged in small packages. In this way, a package of food with a total content of less than one catty is wrapped in three layers of plastic paper inside and outside and can be disassembled. For the food sold in the Expo Park, you can hardly see such complicated packaging.
Second, it refers to the environmental protection of raw materials and technology: this technology is mainly to let consumers eat safe food.
Eat beef, pork, etc. It is equivalent to letting cars run more miles and emit more carbon dioxide, so it is a high-carbon life; Eating wheat flour, rice and other grains is a low-carbon life. Their promotion and influence on human health are different.
Generally speaking, meat food is high in protein and fat, which will lead to many diseases, such as cardiovascular disease, diabetes, kidney disease, cancer and so on. For example, meat and fat contain more saturated fatty acids and low-density lipoprotein, which can lead to cardiovascular and cerebrovascular diseases and cancer; However, cereals are rich in unsaturated fatty acids, vitamins, cellulose and some trace elements, which can reduce and prevent cardiovascular diseases, diabetes, nephropathy, cancer and so on.
