Onions have a pungent taste and can stimulate tears when cut, which makes them unwelcome to many people. In reality, however, onions are hailed as the "queen of vegetables" in Europe and America. Some of its special nutrients are particularly suitable for perimenopausal women to regulate their bodies. Let's take a look at the benefits of eating onions.
I. Benefits of Eating Onions
1. Heart Health
Research has found that the sulfides in onions have anti-thrombotic effects, which help prevent unnecessary platelet aggregation. Studies have also found that the sulfides in onions can lower cholesterol and triglyceride levels and improve red blood cell membrane function. Onions are also rich in antioxidant flavonoids, which, when consumed regularly, can help prevent heart attacks.
2. Increased Bone Density
Multiple studies have found that eating onions helps increase bone density, which is especially important for postmenopausal women with reduced bone density. Another study showed that postmenopausal women who eat onions daily can reduce their risk of hip fractures. The sulfides rich in onions also play a very important role in the formation of human connective tissue.
3. Anti-inflammatory
Onions have significant anti-inflammatory effects. Research has found that the unique sulfide molecules in onions can inhibit the activity of macrophages. The antioxidant substances in onions play an important role in the body's fight against inflammation. These antioxidants can prevent the oxidation of fatty acids in the body. The lower the level of oxidized fatty acids, the fewer inflammatory molecules are produced in the body, and the stronger the ability to control inflammation.
4. Cancer Prevention
Multiple studies have confirmed that moderate consumption of onions can reduce the risk of various cancers such as colorectal cancer, laryngeal cancer, and ovarian cancer.
5. Blood Sugar Lowering and Antibacterial
Multiple studies have found that regular consumption of onions can also improve blood sugar levels and prevent bacterial infections. In addition to sulfides, the flavonoid quercetin in onions also has antibacterial properties.

II. Tips for Selecting Onions
1. Choose onions that feel heavy in your hand, with a dry, tight skin, no bruises, and no smell (because onions release an odor when they are bruised or cut).
2. When selecting onions, the drier the skin and the tighter the layers, the better.
3. From the outside, it's best to see brownish veins within the translucent skin.
4. There are two types of onions: yellow-skinned and purple-skinned. It's best to choose the yellow-skinned ones, as they have thicker layers, more moisture, and a crisper texture. Purple-skinned onions have less moisture, thinner layers, and are more prone to becoming tough.
