11 health benefits of oysters
- Metabolism:
- Oysters are high in vitamin B12, which aids in energy production. About 8 medium-sized oysters provide 230% of the recommended daily value.
- Vitamin B12 boosts metabolism, aids in red blood cell production, and maintains the health of the central nervous system.
- Immune system:
- Raw oysters are high in immune-boosting micronutrients.
- Iron and vitamins C and E in oysters have anti-inflammatory and antioxidant qualities that can help keep germs at bay.
- Bone health:
- Oysters contain iron, copper, zinc, selenium, phosphorus, and calcium, which work together to build stronger bones.
- Heart health:
- Magnesium and potassium help maintain blood pressure by relaxing the blood vessels.
- Vitamin E allows for a stronger cellular barrier, and vitamin C helps combat heart disease and can prevent heart attacks and strokes.
- Mental health:
- Oysters have been shown to improve brain function due to the high amounts of omega-3s, B12, zinc, and iron.
- Studies have shown that the combination of the following nutrients reduce symptoms of depression: vitamins B12, B6, and A, as well as folate, iron, magnesium, potassium, selenium, thiamine, zinc, and omega-3 fatty acids.
- Skin and hair health:
- Zinc and collagen in oysters have been demonstrated to improve skin healing and regeneration.
- Collagen can also help strengthen weak nails and hair.
- Weight loss:
- Oysters are low in calories and saturated fat—6 medium-sized raw or steamed oysters provide fewer than 50 calories and 0.5 grams of saturated fat.
- Therefore, oysters do not interfere with your weight loss or maintenance efforts.
- Cholesterol:
- Oysters have hypolipidemic characteristics, which can help lower lipid levels in the liver and lower cholesterol levels.
- Source of protein:
- Oysters are high in protein, which helps regulate hormones and repair tissue.
- Cells weaken or degrade in the absence of protein, which can lead to autoimmune disorders.
- Protein also helps maintain bone mass and stimulates muscular growth and repair.
- Source of zinc:
- Zinc is the primary mineral involved in the production of testosterone, which increases sexual desire in both men and women. This mineral has been demonstrated to boost male sperm count and female ovarian health.
- Zinc is extremely beneficial to the eyes. Zinc causes increased pigmentation in the eyes, which has been associated with a decrease in the center field of vision.
- Zinc is a mood stabilizer that aids in the treatment of anxiety and other mood disorders.
- Consuming oysters may help prevent diabetes and reduce blood sugar levels. Zinc increases the action of insulin in the body, which can aid in the management of blood sugar levels.
- Source of omega-3 fatty acids:
- Oysters are abundant in omega-3 fatty acids, which help lower blood pressure, promote brain health, and protect against inflammation.
Are there risks of eating oysters?
Although oysters have many health benefits, they should be eaten in moderation. Consumption may also have some side effects:
- Relatively high in sodium, making them a poor choice for people with heart disease or hypertension.
- May contain bacteria called Vibrio that can cause illness when oysters are eaten raw, particularly in those with a weakened immune system. The best way to reduce this risk is to broil or grill before eating.
