About Immune System
Your body's immune system is an amazing network of cells and proteins that protect you against germs, bacteria, and other harmful invaders. This system works throughout the body, connecting with blood vessels and other organs to provide rapid responses to infection.
The immune system consists of two subsystems: innate (non-specific) and adaptive (specific). Innate immune responses rely on cells that don't need the training to do their job, so they occur quickly and reliably.
Adaptive immunity, on the other hand, requires the training and maturation of cells that produce antibodies. These are found in the bone marrow where lymphocytes mature into B cells which then turn into immunoglobulins (antibodies) which attack and destroy pathogens.

Eating a nutritious diet that includes plenty of fruits, vegetables, protein, and healthy fats is one of the best ways to support your immune system. Additionally, it helps reduce oxidative stress and inflammation. Here are the 10 healthy foods to boost your immune system.
Berries are packed with Vitamin C, an essential immune booster. Furthermore, they provide a great source of antioxidants that shield your body from free radicals and unstable molecules that can damage cells and raise the risk of chronic illnesses like cancer. Berries contain antioxidants like lutein, beta-carotene, and lycopene that help improve your skin's health by fighting free radicals that cause sun damage to it. Furthermore, these compounds in berries may prevent wrinkle formation by stimulating collagen production and decreasing inflammation.
One of the best ways to strengthen your immune system is through nutrition.

Citrus fruits are an excellent source of Vitamin C, an immune stimulant that enhances your body's capacity to combat infections. Furthermore, these fruits contain flavonoids with antioxidant properties that protect against damaging free radicals and inflammation. Citrus fruits are not only a great source of Vitamin C, but they also contain other vital vitamins and minerals to support your immune system.
Poultry is an excellent source of zinc, which can strengthen your immune system's capacity to fight infection. Zinc also aids in the production of white blood cells and T-cells, the body's key immune cells, by strengthening their bonds with zinc. Poultry also supplies several immune-stimulating nutrients, such as vitamin C, beta-carotene, and iron. These foods can help keep you healthy all year round but are especially essential during flu season.

This boost in numbers helps your system fight off various infections like cancer.
Olive oil is an ideal choice to boost your immune system as it contains anti-inflammatory, antioxidant, and antimicrobial properties. Furthermore, it contains Vitamin E, which plays a significant role in immune function as well as cellular communication. Furthermore, it provides essential phenols and other compounds which may enhance immunity.
Garlic is an antibacterial, antiviral, and immune-boosting food that can help combat colds. Furthermore, it contains sulfur compounds which combat cancer cells and free radicals in the body. This aromatic veggie can be added to a variety of dishes or consumed as a tea. It has particular health benefits for heart health as it helps lower cholesterol and blood pressure levels.
