Vitamin B12 found in oysters is an important nutrient for maintaining a healthy nervous system. It helps metabolism and blood cell formation easier, especially useful for the elderly.

In addition, oysters also contain selenium, which acts as a strong antioxidant, contributing to the prevention of cell damage caused by free radicals.

Boost Immune System Health

Oyster meat also contains several other minerals that are beneficial to the body’s immune system, such as:

  • Zinc: plays an important role in the immune system as well as metabolism and cell growth.
  • Vitamin D: also has the same effect as zinc and also helps in the growth and flexibility of the skeletal system.
  • Iron: is an essential mineral in the creation of hemoglobin and myoglobin so that the proteins carry oxygen around the body so that the body is healthy.

Support Weight Loss

Oysters are considered a rich source of protein (protein) and contain up to 9 essential amino acids for the body. Scientists have proven that a high-protein diet is more effective at creating satiety and promoting weight loss than a high-carb or low-fat diet.

In other words, foods rich in protein will stabilize hunger by increasing levels of hormones, to induce a feeling of fullness due to the presence of peptide YY and cholecystokinin (CCK).

Helps Control Blood Sugar

Consuming more protein in the body also helps control blood sugar levels, especially beneficial for people with diabetes.

For example, in a review of nine studies, a high-protein diet significantly reduced hemoglobin A1c levels in people with type 2 diabetes. Hemoglobin A1c is a marker of sugar status. in blood.

Moreover, in an analysis of 18 other studies, it was found that high protein consumption also significantly reduced mean cholesterol levels, which is considered a risk factor for heart disease in people with diabetes. type 2.

Supports Liver Health

Oysters are not only packed with vitamins but also contain an outstandingly powerful antioxidant compound called DHMBA (full name is 3.5-Dihydroxy-4-methoxybenzyl alcohol), which is beneficial for the liver and heart health.

DHMBA belongs to phenolic compounds, acts as a powerful antioxidant, 15 times more than Trolox (which is a synthetic form of vitamin E and is used to prevent oxidative stress).

Specifically, according to in vitro studies, it has been shown that: DHMBA can protect human liver cells from damage and destruction of liver cells due to the activity of oxidative stress. In addition, scientists also expect that adding DHMBA compounds will have more effects in the treatment and prevention of liver-related diseases shortly.

Support for Healthy Bones

Despite being low in calories, oysters contain many other minerals such as calcium, selenium, zinc, phosphorus, copper, and iron that all contribute to increased bone density and strength.

Good for the Brain

Thanks to the significant amount of vitamin B12 and omega-3, oysters become a portion of good food for brain development in children as well as improving brain function in adults.

Promotes Heart Health

Thanks to the anti-inflammatory properties of omega-3, oysters help reduce the risk of cardiovascular disease.

For example, in a study of 18,244 healthy men in China, it was found that the group of people who ate 200g of shellfish (including oysters) per week reduced the risk of dying from heart disease by about 59% compared to the group of people who ate less (only ate 50g) per week.

In addition, the results of other epidemiological studies have further demonstrated: DHMBA also reduces the oxidation of LDL (bad) cholesterol – a factor associated with atherosclerosis and also a cause of heart disease.

Without enough vitamin B12, the body tends to have increased levels of homocysteine ​​in the blood – a protein that increases the risk of cardiovascular disease.

Men’s Health Support

Oysters are famous for supporting men’s health, because of their significant zinc content.
