- Garlic: Garlic is a good source of allicin, a compound that has antiviral and antibacterial properties. Allicin can help to boost the immune system and protect against infection.
- Ginger: Ginger is a good source of antioxidants and has anti-inflammatory properties. Ginger can help to boost the immune system and reduce inflammation.
- Yogurt: Yogurt is a good source of probiotics, which are live bacteria that are beneficial for gut health. Gut health is important for a healthy immune system.
- Nuts and seeds: Nuts and seeds, such as almonds, walnuts, and sunflower seeds, are a good source of vitamin E, zinc, and other minerals. Vitamin E is an antioxidant that helps to protect the body’s cells from damage. Zinc is an essential mineral that plays a role in many bodily functions, including immune function.
In addition to eating a healthy diet, there are other things you can do to boost your immune system, such as getting enough sleep, exercising regularly, and managing stress.
It is important to note that there is no single food or nutrient that can guarantee a healthy immune system. However, eating a balanced diet that includes a variety of nutrient-rich foods can help to support your immune system and protect you from infection.
Foods that can help the immune system function better
1. Eggs
Eggs are a good source of several nutrients that are important for immune function, including:
- Protein: Protein is essential for building and repairing tissues, including immune cells.
- Zinc: Zinc is a mineral that plays a role in many aspects of immune function, including the production of white blood cells and antibodies.
