A snail is a small mollusk with a spiral-shaped shell. Snails are famous for moving very slowly and leaving a trail of slime behind them. They all have shells that they can retreat into.
Health benefits of consuming snailsRisks and side effects of consuming snails
You may think of snails only as animals that wreak havoc in your garden or crawl on the sidewalk after it rains. But in many parts of the world snails are actually a delicacy.
In this article, Tribune Online discusses the health benefits of eating snails and the possible risk of eating them if they are not properly prepared:
Health benefits of consuming snails
1. Rich source of protein and micronutrients
Snail meat offers a lean protein source and, compared to some meats, has a lower fat content. It also contains minerals such as iron, calcium, and vitamins such as A. These nutrients support functions such as immunity, bone strength, vision, and healthy red blood cell production. Some studies also suggest that snail slime may influence blood sugar regulation.
2. Moisturizes and protects the skin
The slimy mucus (or whey) of snails includes oligosaccharides and other wetting agents that help retain water. When used topically in creams or serums, they can soothe irritation, brighten skin, and protect against environmental damage. Research on the effects of snail mucin on the skin sample improved hydration, elasticity and wrinkle reduction in human and animal skin models.
3. Supports skin and helps bone repair
Snail secretions are rich in compounds such as allantoin, collagen, and elastin, which are ingredients commonly found in skin care products. These substances are beneficial in promoting skin healing and may aid in bone repair. Additionally, snail mucus often contains copper peptides, which are used in many creams to reduce scars and heal wounds.
Risks and side effects of consuming snails
1. Cardiac and arterial risk from fatty preparations
Snail meat itself is not typically high in unhealthy fats, but when cooked in rich, heavy oils, the added fats can build up on artery walls over time. This increases the risk of clogged arteries, increasing the chance of heart attacks or strokes.
2. Parasitic infections: rat worm lung disease
If snails are eaten raw or undercooked, they can carry parasites such as Angiostrongylus cantonensis (rat lungworm). When these parasites are ingested, they can cause neurological symptoms such as headaches, fever, neck stiffness, vomiting, and in rare cases, severe brain damage.
3. Contamination and bioaccumulation
Snails collected from contaminated environments may accumulate heavy metals (e.g., lead, cadmium) or toxins. Regular consumption of contaminated snail tissue could pose risks to the kidneys, liver or other organs over time.
