Falling Sick Constantly? 7 Natural Foods To Boost Your Immunity

Building a strong immune system is crucial to a healthy and strong body. If you are falling sick constantly, it’s time to pay attention to your body and strengthen your immune system with these 7 natural immunity booster.

Citrus Fruits

Do you turn to oranges or other sources of Vitamin C to fight common ailments such as after you’ve caught a cold? That’s because of the Vitamin C in these citrus fruits. Vitamin C is thought to be able to give your immune system a boost by helping to increase the level of white blood cells in the body which is essential to fighting off infections. As our body neither produce nor store Vitamin C, it is important to include them in your daily diet! Some fruits include: 

  • Orange
  • Lemon
  • Grapefruit
  • Limes


Cauliflower is one of the most nutritious vegetables you can put on your table. Resembling a mini tree, it is packed with antioxidant vitamins and minerals that give your immune system a boost. It is good to reach for cauliflower when you’re sick as it contains a powerful antioxidant called glutathione that helps to fight off infection. Besides that, it also contains choline, a nutrient that helps to keep your gut strong and healthy, ensuring that any bacteria consumed will not spread to the rest of the body. 


Did you know that garlic can increase the production of the natural killer cells in your body, boosting your immune system? These cells are the body’s natural response to any infected cells. With a healthy level of natural killer cells, they can contain the infected cells, keeping you healthy and strong. Other than fighting off infections, there are many other health benefits of consuming garlic, such as lowering your blood pressure, reducing your cholesterol and also regulating blood sugar levels.     


Have your mom made you ginger tea or porridge cooked with ginger slices whenever you’re sick? That’s due to their well-known anti-inflammatory properties and antioxidant effects. Eating ginger can help you combat inflammation when you’re sick, but try to incorporate ginger into your daily diet to keep your immune system healthy and strong.     


Loaded with prebiotics, they keep our gut healthy. Not only that, yoghurt are a great source of Vitamin D that can help to regulate your immune system, giving it a boost. However, for the most nutritional form of yoghurt, look for Greek yoghurt which is unflavoured. Try adding a spoon of honey or add some fresh fruits for taste. 


Green Tea

Green tea is well-known for its anti-oxidant properties. It contains a type of potent plant antioxidants called polyphenols which is believed to help kill influenze viruses. It is also rich in L-theanine, an amino acid that can aid you in the production of germ-fighting compounds in your body. Steep the tea bag for a minute or two and do not add milk as it will make the properties of green tea ineffective. 


Shellfish might come to be a surprise for many when we try to link them to boosting immune system. But shellfish are packed with zinc, which is essential for our immune cells to function properly. However, do note that you should not consume more than the daily recommended intake as it can actually inhibit your immune system from functioning. As a general guideline, men should take no more than 11mg of zinc daily and 8mg of zinc for women.
