In fact, many of our current nutrition concepts come from enterprises. It is said that people need a variety of vegetables and nutrients a day, and their bodies lack protein and trace elements. In fact, most of these publicity comes from businesses. Merchants' propaganda is full of our eyes, and advertising language keeps entering our brains, indirectly forming a seemingly scientific theory. In fact, businesses do these advertisers mainly to sell products. When people say that everyone is short, they will worry about the adverse reactions caused by the so-called insufficient intake, so they will naturally buy the products.

In fact, we humans are now in an era of extremely rich nutrition. If it is still undernourished, it is estimated that human beings will not live long in history. Supermarkets can be seen everywhere on street corners, and most farms harvest automatically. We can eat meat and all kinds of food every day, which was unimaginable in the past. In the past, where people grew up, they could only eat local ingredients.
