Onion is the most planted vegetable in the world, and its nutritional value is very high, known as the "Queen of Vegetables".
Onions not only contain nutrients that the body needs, but onions also have many medicinal properties, including antioxidant, anticancer, anti-inflammatory, antibacterial, anti-virus and so on.
It should be mentioned that onions contain some fructans, which most vegetables do not.
Fructan is a carbohydrate with health-care functions, which can reduce the production of tumor-related substances and has a good effect on preventing cancer and other chronic diseases.
Fructan is also a nutrient for good bacteria in the gut, which can increase the number of good bacteria.
However, There May Be Some Side Effects after eating too much onion.
There are no enzymes in the gut that can decompose fructans, so fructans cannot be digested and absorbed by body.
Large amounts of fructans accumulate in the gut and may cause gut problems such as bloating, abdominal pain, gas, and cramping.
Therefore, you can't eat too many onions, and it is advisable to eat 50 grams to 80 grams a day.
