Health Benefits of Oysters

For centuries, oysters have been eaten raw. However, some people opt for oyster sauce or take oyster supplements.

Oyster sauce is used in Vietnamese, Thai, and Chinese cuisines as a tempering while cooking noodles, vegetables and stir fries or as a marinade. It is made by slowly simmering oysters in water until the juices caramelize into a thick, brown and intensely flavourful sauce. A vegetarian version of oyster sauce is made using oyster mushrooms.

Oyster Extract is useful for the body and liver cleansing as it promotes secretion of bile and enhances liver functions. Oyster shell calcium supplements are used to treat osteoporosis, indigestion and heartburn. These supplements are also useful for post-menopausal osteoporosis prevention. Oyster capsules arenít only high in zinc; they include numerous compounds, which benefit general health. They help in boosting glutathione levels, which aid in transportation of proteins and nutrients into the cell, energy production and in slowing down the aging process.

Aphrodisiac: The legendary lover, Casanova was said to have consumed 50 oysters for breakfast each morning, for its spectacular sexual benefits. Zinc has been closely linked to sexual dysfunction in men, while impotence and erectile dysfunction are closely associated with zinc deficiency. As an abundant source of zinc, oysters can help boost sexual performance and libido in men. Oysters increase dopamine levels, which boosts the level of sex hormones.

Oysters Boost Sexual Performance

Brain food: Oysters are good sources of Vitamin B 12, Omega 3 fats, iron and zinc, which boost memory and brain functioning. Low iron reserves reduce the ability to concentrate, whereas lower levels of zinc affect memory. Omega 3 fatty acids are a key component in brain functioning.

Weight Loss: Oysters represent one of the most nutrient-packed foods with the lowest calories versus its serving size. Compared to an equal serving size of chicken, oysters provide nearly half the calories making them a dieterís dream.

Heart Health: Oysters can positively impact heart health in a variety of ways. The high levels of Omega-3 fatty acids reduce the chances of plaque accumulation thereby reducing the risk of arteriosclerosis. The potassium and magnesium content of oysters help in lowering blood pressure by relaxing the blood vessels.

Wound Healing and Immunity: The unprecedented levels of zinc in oysters result in a number of health benefits, including quicker wound healing rates, and a strong immune system to combat various infections.

Blood Circulation: Oysters are a fair source of iron, which is a key component of hemoglobin that carries oxygen to the cells. A steady supply of oxygen makes the various organ systems function efficiently and boosts the overall metabolic rate of the body. Being an animal source, the bioavailability of iron in the oysters is considerably high.

Oysters Helps in Blood Circulation

Bone Health: The blend of bone-friendly minerals such as calcium, phosphorus, zinc and copper contribute in their own way to increasing bone mineral density, thereby protecting from osteoporosis.

Potential Health Risks

In addition to the risk of shellfish allergies or accidental zinc overdose, oysters pose a potential health risk because of their moderately high cholesterol content. As oysters absorb nutrients from the areas where they grow, it is possible that some oysters contain pollutants and certain toxins, which can be detrimental to health. Furthermore, the high sodium content can be dangerous for people who are already at a risk from heart diseases or high blood pressure.

Eat oysters as a treat once in a while, and you can enjoy the vast wealth of health benefits they have to offer.
