Vegetables are rich in vitamins, minerals, and dietary fiber. Eating an appropriate amount of vegetables can promote intestinal peristalsis, promote bowel movements, provide the micronutrients the body needs, exert antioxidant effects, and ensure the normal function of various organs in the body. However, excessive intake of vegetables can also have various harms.
Certain vegetables contain more oxalic acid, which is easy to form stones. Vegetables such as spinach, celery, and tomatoes contain more oxalic acid, which can easily combine with calcium in other foods to form calcium oxalate stones. This is one of the reasons why many women who like to eat vegetarian are prone to stone diseases.
It can easily aggravate the condition of stones.
Most vegetables are alkaline foods. For patients who already have calcium phosphate stones, eating a large amount of alkaline foods daily can increase the number of stones and make them difficult to excrete from the body.
Not easy to digest.
Vegetables with high crude fiber content, such as celery and spring bamboo shoots, are difficult to digest after being eaten in large quantities, and are not suitable for patients with gastrointestinal diseases to eat in large quantities. Crude fiber can also easily cause gastric bleeding or esophageal variceal bleeding in patients with cirrhosis, aggravating the condition.
Affects the absorption of calcium and zinc.
Pregnant women and children and adolescents in the growth and development period, a large intake of vegetables will hinder the body's absorption of calcium and zinc, affecting children's intellectual development and bone growth.
If a large amount of vegetables are eaten for "dieting" or "satiety", reducing or abstaining from meat and fish will not only affect the body's intake and absorption of essential fatty acids and high-quality protein, causing protein malnutrition, but also hinder the absorption of rich nutrients such as calcium, iron, and zinc from non-vegetarian foods. Women should pay special attention to avoiding iron-deficiency anemia and calcium deficiency caused by excessive vegetarianism.
