What are the benefits and effects of lettuce?

Generally, lettuce has various health benefits and effects, including strengthening physical constitution, promoting intestinal health and relieving constipation, protecting the eyes, lowering blood pressure, and reducing blood sugar levels. The details are as follows:

1. Strengthening Physical Constitution

Lettuce is rich in nutrients such as protein, dietary fiber, vitamins, and minerals. Consuming it in moderation provides essential nutrients to the body, helping strengthen overall physical health and enhance disease resistance.

2. Promoting Intestinal Health and Relieving Constipation

Lettuce contains abundant dietary fiber, which can promote gastrointestinal motility and accelerate the elimination of waste from the body. Therefore, moderate consumption of lettuce helps moisten the intestines and relieve constipation.

3. Protecting the Eyes

Lettuce is rich in lutein and zeaxanthin, which can help delay eye aging. Additionally, lettuce contains small amounts of carotene, a substance that can be converted into vitamin A in the body, helping alleviate dry eyes and protect vision.

4. Lowering Blood Pressure

Lettuce contains a high amount of potassium ions. Potassium helps dilate arteries and reduce peripheral vascular resistance. Thus, consuming lettuce in moderation helps regulate sodium balance in the body, accelerates metabolism, and contributes to lowering blood pressure.

5. Reducing Blood Sugar Levels

Sodium glutamate in lettuce helps regulate blood glucose levels. Meanwhile, the dietary fiber in lettuce can slow down the absorption of sugar and lipids in the small intestine, helping lower blood sugar and aiding in the prevention and management of diabetes.

In daily life, lettuce offers many health benefits, but it should be consumed in moderation. Individuals allergic to this food should avoid it. If any physical discomfort occurs after eating lettuce, medical attention should be sought promptly.
