A study in 42 people with type 2 diabetes demonstrated that eating 3.5 ounces (100 grams) of fresh red onion reduced fasting blood sugar levels by about 40 mg/dl after four hours.
Additionally, multiple animal studies have shown that onion consumption may benefit blood sugar control.
Specific compounds found in onions, such as quercetin and sulfur compounds, possess antidiabetic effects.

Onions may kill a wide range of bacteria. In one experiment, onion and garlic extracts inhibited the growth of several microbes. Garlic extract also reduced bacteria in the mouths of human volunteers.
⦁ Reduce Cancer risks:
Eating onions and garlic may reduce your risk of cancer. Researchers found that men who ate the most vegetables of the allium family were the least likely to have prostate cancer. Researchers believe that antioxidants are responsible for the cancer-fighting properties of onions.

A study in 24 middle-aged and postmenopausal women showed that those who consumed 3.4 ounces (100 ml) of onion juice daily for eight weeks had improved bone mineral density and antioxidant activity compared to a control group.
studies demonstrated that older women who most frequently ate onions decreased their risk of hip fracture by more than 20% compared to those who never ate them.
Onions help reduce oxidative stress, boost antioxidant levels and decrease bone loss, which may prevent osteoporosis and boost bone density.
⦁ Contain many of Antioxidants:
Antioxidants are compounds that inhibit oxidation, a process that leads to cellular damage and contributes to diseases like cancer, diabetes and heart disease.
Onions are an excellent source of antioxidants. In fact, they contain over 25 different varieties of flavonoid antioxidants.
Red onions, in particular, contain anthocyanins — special plant pigments in the flavonoid family that give red onions their deep color. Multiple population studies have found that people who consume more foods rich in anthocyanins have a reduced risk of heart disease.
