Daily consumption of onions: 8 amazing benefits for the body

Humble vegetable with superpower: scientists reveal 8 amazing health properties of onions

According to TUT.AZ with reference to verywell health, this common ingredient not only gives dishes a unique taste but is also a real treasure trove of beneficial substances that can significantly improve health.

Natural antibiotic in your kitchen

Onion effectively fights three dangerous types of bacteria:

Escherichia coli (E. coli)

Staphylococcus aureus (S. aureus)

Bacillus cereus

Scientific data confirms that quercetin — one of the key flavonoids in onions — successfully suppresses the growth of numerous bacterial strains.

Powerful anti-inflammatory effect

The flavonoid-rich composition of onions provides reliable protection for the body against free radicals. Numerous studies involving people have proven a direct link between quercetin levels and its immunomodulatory effect. Scientific work from 2016 convincingly showed the positive impact of increasing consumption of this substance.

Antioxidant shield for the body

Similar to other members of the Allium family — garlic, leeks, and shallots — common onions contain a whole complex of protective substances:

flavonoids

glutathione

selenium compounds

vitamins E and C

These components collectively multiply its antioxidant potential many times over.

Natural blood sugar regulator

Animal experiments have demonstrated impressive results: extract of Allium cepa bulb significantly lowers elevated blood sugar levels. When the extract was used in combination with metformin, fasting glucose levels decreased by 35-50% depending on the dosage. This makes onion an accessible and promising means of maintaining healthy sugar levels.

Defender of the bone system

Scientists have discovered that the GPCS peptide contained in onions actively prevents bone tissue destruction, slows bone mass loss, and significantly reduces the likelihood of fractures.

Ally of healthy digestion

Onion is among the best natural prebiotics that effectively protect the intestinal mucosa. It contains inulin — a substance that stimulates the growth of beneficial intestinal microflora.

A real vitamin and mineral bomb

With minimal calorie content, onion provides the body with a whole complex of nutrients. Half a cup of raw onion contains only 30 calories, 0 g fat, 7 g carbohydrates, 1 g protein, as well as iron, potassium, calcium, vitamins C and B6, folic acid, zinc, and selenium.

Helper in weight control

Excess weight is inextricably linked to metabolic disorders and inflammatory processes caused by excessive consumption of saturated fats. Regular inclusion of onion in the diet helps reduce total body mass, decrease fat deposits, and normalize triglyceride levels.

How to get maximum benefits

Onion retains its beneficial properties in both raw and cooked form. However, heat treatment reduces the content of thiosulfinates — substances that provide its antimicrobial, antifungal, and antibacterial properties.

Specialists recommend chopping onions before cooking — this simple technique helps maximize
