Not only are they delicious, oysters hold impressive health benefits that come from its vast stockpiles of minerals, vitamins, and organic compounds. The other components include very high levels of protein, vitamin D, vitamin B12, iron, copper, manganese, and selenium. Oysters also contain high levels of niacin, riboflavin, thiamin, vitamin C, phosphorus, potassium, and sodium. Finally, oysters are a huge source of beneficial cholesterol, antioxidants, omega-3 fatty acids, and water. These elements of oysters make them an extremely healthy food that can seriously boost your body’s overall function and health. Good for the heart and soul!
High Protein, Low Calories
Oysters represent one of the most nutrient packed foods with the lowest calories versus the volume of serving size. This means that people trying to lose weight can keep their body packed with the nutrients it needs, without adding too much weight on their frame. Compared to an equal serving size of chicken, oysters have about the same amount of protein but nearly half the calories..
Oysters can positively impact heart health in a variety of ways, but primarily, the high levels of omega-3 fatty acids versus omega-6 fatty acids are what impact the cholesterol so greatly. Omega-3 fatty acids are known as “good” forms of cholesterol, and the high ratio of “good” to “bad” cholesterol (omega-6 fatty acids) makes oysters a major player in heart health. It can reduce the content of bad cholesterol in the blood stream and inhibit it from binding to blood vessel and artery walls. In this way, it reduces the chances of plaque accumulation and a variety of health complications, including cardiovascular disease. Furthermore, the high potassium and magnesium content of oysters can help to lower blood pressure and relax the blood vessels, thereby increasing circulation and oxygenation of the blood and reducing strain on the cardiovascular system as a whole. Finally, the vitamin E in oysters increases the strength and flexibility of cellular membranes, which is a third level of protection against dangerous heart diseases.
The high levels of calcium, phosphorus, zinc, iron, copper, and selenium all contribute in their own way to increasing bone mineral density and durability, thereby protecting your from developing conditions like osteoporosis, premature aging, and general body disrepair wherever they lodge themselves. Antioxidants and various vitamins can eliminate these free radicals from the body, thereby boosting the immune system.
Oysters are also a very impressive source of iron, with more than 90% of our daily requirements in each serving. Iron is a key component in the formation of red blood cells in the body, and are the primary defense against anemia, also known as iron deficiency, which can lead to fatigue, cognitive malfunction, stomach disorders, and general muscle weakness. Also, with a fresh supply of healthy blood cells in the circulatory system, organ systems have high levels of oxygenated blood to stimulate their activity, making them function efficiently and boosting the overall metabolic rate of the body.
Aphrodisiac - proven by science
The team of American and Italian researchers analysed bivalve molluscs - a group of shellfish that includes oysters - and found they were rich in rare amino acids that trigger increased levels of sex hormones. Oysters contain rare amino acids, which are not commonly found in nature. These two amino acids -- D-aspartic acid (D-Asp) and N-methyl-D-aspartate (NMDA) -- play a role in hormone synthesis. D-aspartic acid has been found to temporarily increase testosterone levels and improve sperm motility. NMDA is an agonist (a substance that initiates a physiological response) that can increase neural excitability.
