Scientific Evidence and Case Studies
Green onions have been shown to have a number of health benefits, including reducing the risk of heart disease, stroke, and cancer. These benefits are due to the presence of sulfur compounds and flavonoids in green onions.
One study, published in the journal Nutrition and Cancer, found that eating green onions was associated with a reduced risk of stomach cancer. The study followed over 1,000 people for a period of 10 years. Those who ate green onions at least once a week had a 30% lower risk of developing stomach cancer than those who did not eat green onions.
Another study, published in the journal Circulation, found that eating green onions was associated with a reduced risk of heart disease. The study followed over 2,000 people for a period of 5 years. Those who ate green onions at least twice a week had a 20% lower risk of developing heart disease than those who did not eat green onions.
These studies provide evidence that green onions have a number of health benefits. However, it is important to note that these studies are observational studies, which means that they cannot prove that eating green onions causes a reduced risk of disease. More research is needed to confirm the health benefits of green onions.
Despite the need for more research, the evidence suggests that green onions are a healthy food that can be included in a healthy diet.
