Onions

It is imperative to note that all types of onions (white, red, and yellow varieties) have health benefits and can be included as part of a healthy diet. That said, a number of studies show that certain types of onions may have higher levels of beneficial compounds than others. For instance, yellow onions have high levels of sulfur compounds (allicin and quercetin) which have been linked to improved immune function and lower inflammation.
Consequently, red onions have been dubbed as incredibly healthy owing to their high levels of anthocyanins. Anthocyanins are antioxidant compounds that give the onion its red color. These antioxidant compounds are believed to drastically reduce the risk of certain types of cancer, lower inflammation levels, and improved heart health.
White onions on the other hand have similar compounds to yellow onions but in lower concentrations. But, they are still a very good source of Vitamin C, fiber, and other micronutrients. To sum it up, the healthiest type of onion is depended on a person’s tastes and preferences as well as specific health needs. You can use all types of onions as part of a healthy diet.

There is no scientific evidence as of now that suggests or supports the claim that onions clean stomachs. What is known is that onions do have compounds that may be beneficial or support digestive health. Onions are rich in fiber which is a very key nutrient in maintaining a healthy digestive system. Fiber supports the growth of healthy gut bacteria, promotes regular bowel movements, and prevents constipation.

In a nutshell, while onions might not clean the stomach in the traditional sense, they do contain compounds that support digestive health.
