Oysters

Oysters are a rich source of minerals, especially zinc - a great micronutrient for boosting the immune system. Zinc contains several antiviral components, which are essential for fighting invading diseases.

In fact, oysters are low in calories but packed with nutrients, including healthy fats, vitamins, protein and minerals. It is estimated that a 100-gram serving of oysters will provide more than 100% of the RDI for zinc, copper and vitamin B12, and more than 75% of the RDI for selenium and vitamin D. This seafood is also an excellent source of protein and omega-3 fatty acids. According to experts, eating a lot of oysters also helps strengthen the immune system and reduce the risk of diabetes. The anti-inflammatory and antioxidant properties of oysters also protect against free radicals that do harm the body.
