Excuse me: What harm does eating raw "lettuce" have to human body, and is it harmful to the heart?

Without high temperature, of course, it is easy to bring bacterial pesticides on lettuce into the human body, and there may be eggs! Therefore, cold dishes should not be eaten, but should be washed as clean as possible! Whether it is "lettuce" or "raw vegetables", as long as there is no deterioration and no pesticide residue, it is generally not too harmful.

Raw "lettuce" is crispy and delicious, refreshing and pleasant. Raw lettuce is more nutritious than cooked lettuce, and it will definitely destroy the nutrients in vegetables after cooking. Lettuce is extremely rich in nutrients, including antioxidants, beta carotene, vitamins B 1, B2, B6, vitamin C and vitamin E, and also rich in trace elements and dietary fiber, including calcium, phosphorus, potassium, sodium, magnesium and a small amount of copper, iron and zinc. Eating lettuce regularly can improve gastrointestinal blood circulation and promote the digestion and absorption of fat and protein. Lettuce can also protect the liver, promote bile formation, prevent cholestasis and effectively prevent gallstones and cholecystitis. In addition, lettuce can remove the garbage in the blood, which has the functions of blood disinfection and diuresis, and can also remove intestinal endotoxin and prevent constipation. Most vegetables contain an immune substance-interferon inducer, which acts on the interferon gene of human cells and has the functions of inhibiting cancer and antiviral infection of human cells. But this "interferon inducer" can't withstand high temperature, and only raw vegetables can play a role.

The latest research by scientists found that spherical lettuce contains a protocatechuic acid substance, which has obvious inhibitory effect on pancreatic cancer. In the past, protocatechuic acid was known to have certain inhibitory effects on tongue cancer, gastric cancer, liver cancer, colorectal cancer and bladder cancer. Now it is considered that it also has obvious inhibitory effect on pancreatic cancer.

Lactucin is an ingredient in the stems and leaves of lettuce, so we may feel a little bitter when eating lettuce, but it is a rare good thing for the human body. It has the functions of relieving pain and hypnosis, lowering cholesterol, assisting in the treatment of neurasthenia, promoting diuresis and relieving atrial pressure, which is very beneficial to patients with hypertension and heart disease.

Life is full of knowledge. Even the lettuce we usually eat has so many functions. It seems that the best medicine is food. A thorough study of food is really good for our health.
