What are the common misunderstandings of traditional knowledge in life?

Sweeteners help to lose weight. Some sweeteners, such as xylitol, also contain calories, and excessive intake can also lead to obesity.

Salad is very beneficial to human health. Salad sauce is high in calories, fat and low in nutritional value. Experts suggest that you can mix vegetables and fruits with yogurt, which is delicious and nutritious, and can also supplement calcium.

Drinking beer will make you fat. In fact, the calories of beer are not high. The calorie of 0.5 liter beer is 160 calories. "Drinking in a big bowl and eating meat in a big mouth" can lead to obesity, and too many appetizers are the main culprit.

Eating vegetables raw is more healthy. Eating raw or cooked depends on nutritional needs. If tomatoes are eaten raw, the loss of vitamin C is the least, and heating will lose vitamin C, and the lycopene contained in them needs heating to be better absorbed. Similar vegetables include carrots and so on.
