We all acknowledge the importance of a healthy lifestyle. It not only depends on your workout routine but also on the kind of food you eat. Eating the right food not only helps you stay lean but boosts your immune system which is your body’s defence against infections. Your immune system consists of organs, cells, tissues, and proteins. Together, these carry out functions that fight off pathogens, which are the viruses, bacteria, and foreign bodies that cause infection or disease. The stronger your immune system, the healthier you will be. This is why eating the right food to increase immunity is essential for your health.
While there are plenty of immune boosting foods, you should also be aware of foods that weaken the immune system.
Below are a few foods that should avoid to have a good immune system:
Soda is made of artificial colouring, artificial sweeteners, and artificial flavours that make you fat. Keeping the weight issue aside, soda has damaging effects like decreased brain function, moodiness, allergies, and suppresses your immune system. It is advised to skip soda as it has zero nutritional value. Soda is associated with weight gain, risk of type 2 diabetes, and increased risk of cardiovascular disease.
When you are tired, it seems convenient to go and grab a packet of chips from your kitchen shelf. But, have you ever stopped for a minute and wondered about its effect on your immune system? A large number of calories in processed food may lead to numerous health problems like auto-inflammatory disease, increased inflammation, and reduced control of infection. Did you know that your poor diet choices get encoded into your DNA scaffolding and the gut microbiome? This means that your food habits can permanently change the balance of bacteria in your body, therefore, can weaken the immune system.
You must have heard of good carbohydrates and bad carbohydrates. Basically, refined carbohydrates (also known as processed carbs) are bad for one’s health. Refined carbs are basically present in two kinds of food - sugars and refined grains. The main dietary sources of refined carbohydrates are white flour, white bread, white rice, sodas, maida, sweets, breakfast cereals, and added sugars, of course.
These foods disrupt the integrity of your gut microbiome and the good bacteria it contains, leading to a weakened immune system that further makes you prone to various diseases. Refined carbs and sugar-filled diets are also linked to chronic diseases such as cancer, diabetes, kidney disease, heart disease, digestive disorders, etc.
Alcohol can affect us in many ways, but did you know it can weaken your immune system too? Let’s understand how alcohol affects your immune system. Alcohol can disrupt the gut barrier, further allowing more bacteria to pass into the blood. These rogue bacteria can cause inflammation in the liver which can further lead to liver damage. When you drink a lot of alcohol, it can also disrupt your digestive system. Hence, it is advisable to avoid drinking alcohol.
Now that you know about the foods that weaken the immune system, let’s have a look at immune boosting foods and drinks. Feeding your body with immune boosting foods can help you prevent winter cold and other various infections. So, it’s important to eat nutrient rich foods to improve immunity so you stay stronger.
Immune System booster foods
We all had been forced by your parents to eat a lot of spinach when we were a kid, right? This is because spinach is one of the best immune boosting foods. Spinach is rich in Vitamin C that helps fight infections. Spinach is also rich in various antioxidants, which are known to increase the infection-fighting ability of your immune system.
Tip: Cook your spinach as little as possible because light cooking enhances its Vitamin A and allows other nutrients to be released from oxalic acid.
This green vegetable is super rich in vitamins (Vitamin A, Vitamin C, Vitamin E, and Vitamin K ) and minerals. It is rich in numerous antioxidants that make it one of the best immune boosting foods. Eating broccoli is good for your digestive system because of the fibres present in it.
Tip: Boiling can leach most of the valuable nutrients from your green veggies like spinach and broccoli. Therefore, just like spinach, cook your Broccoli as little as possible so that it retains its nutrients - or better, eat it raw!
Garlic has been used from centuries as the early civilization realized its infection-fighting properties. Today, garlic is found in almost every home and used in many cuisines. It also adds a good flavour to the food. Garlic’s immune-boosting properties come from a heavy concentration of a sulfur-containing compound called allicin. When garlic is eaten, alliin compound turns into allicin that gives garlic its distinctive smell and taste. Allicin is an unstable compound, so it quickly turns to sulphur containing compounds that give garlic its medicinal properties.
Tip: Adding garlic daily in your food helps prevent the common cold and flu. And eating garlic when you’re sick can help you recover faster.
Ginger has been used as a medicine for common cold and flu for centuries. Ginger is packed with gingerols, paradols, sesquiterpenes, shogaols, and zingerone. These consist of powerful anti-inflammatory and antioxidant properties that make it one of the best foods to increase immunity. Ginger also soothes nausea and digestive ailments, like bloating and indigestion. Ginger also helps in weight loss, diabetes, and exhibits anti-cancer properties.
Yogurt is one of the healthiest foods to turn to when you’re looking to eat something yummy. Probiotics (friendly bacteria that are also present in your digestive system) present in yogurt makes it an immune system booster food. These probiotics boost the healthy bacteria in your body thus helps to boost your immune system.
Tip: There are many ways to add yogurt to your daily diet - add yogurt to your oats, or use it as a base for salad dressings, or eat it with fruits. Nothing can go with yogurt!

It helps you fight cold and recover faster and protect you from falling sick in the first place. The protein in chicken and turkey also provides you with amino acids, which are used by your body to build antibodies to fight infection.
Tip: Boiling poultry—to make soup—releases gelatin, chondroitin, and other nutrients that help your gut and immune system as well.
Almonds are rich in iron, protein, and Vitamin E that acts as antioxidants and are essential for your immune system. Eat a handful of almonds daily to boost your immune system and sharpen your memory.
Tip: Add almonds to your oats, yogurt, or eat them directly as snacks. You can also soak almonds overnight and then eat them.
