Lettuce is a nutritious vegetable rich in vitamins, minerals, and dietary fiber, but why eat less lettuce?
First of all, lettuce contains more oxalic acid, which will combine with calcium in food to form calcium oxalate that is not easily absorbed by the human body, and long-term consumption will affect the body's absorption of calcium. In addition, oxalic acid may also affect zinc absorption, leading to zinc deficiency in the body.
Secondly, lettuce has a high content of dietary fiber, and if you consume too much, it will increase the burden on the gastrointestinal tract, especially for people with weak gastrointestinal function, which is easy to cause diarrhea, abdominal pain and other uncomfortable symptoms.
In addition, lettuce contains a substance called lettuce, which has a bitter taste, and if eaten raw or in excess, it will cause a bitter feeling in the mouth and affect the taste.
In addition, lettuce is rich in vitamins and minerals, but its content is not particularly high, and if lettuce is eaten as a main vegetable for a long time, it may cause malnutrition.
To sum up, although lettuce has a certain nutritional value, we should eat it in moderation and avoid excessive intake. Especially for people with a weak gastrointestinal tract, lettuce should be consumed with caution. At the same time, we should also pay attention to the diversity of our diet and reasonably mix a variety of vegetables and fruits to obtain comprehensive nutrition.
