Green leafy vegetables are rich in calcium, magnesium and potassium, especially amaranth, spinach, celery, lettuce, water spinach and oil wheat. So it is recommended to eat green leafy vegetables every day. How much should I eat?

The Dietary Guide for China Residents suggests that you should eat 300-500g of vegetables every day, among which dark vegetables such as green, orange, red and purple account for at least 1/2, and green leafy vegetables are the main force in dark vegetables, so you should eat more than 100g anyway.
