As we move forward, you’ll learn about the best foods to boost your immune system. We’ll cover everything from fruits, vegetables, and other natural ways to strengthen your immunity. So, keep reading to fight off infections and stay healthy.
What is the Immune System?
Your immune system is your body’s defense against outside threats like viruses. It’s made up of cells, tissues, and organs that recognize when something harmful, like the flu virus, enters your body. It then starts a response to help you get better, mainly using white blood cells.
If your immune system is strong, you’re better at fighting off illnesses. But if it’s weak, you’re more likely to get sick.
The immune system is also important in battling diseases like cancer. For example, immunotherapy is a treatment that activates your immune system to attack cancer cells. Because the immune system is so important to your health, it’s essential to keep it strong.
Can Certain Foods Really Strengthen Your Immune System?
Eating specific foods won’t magically cure you when you’re sick, but having a diet rich in vitamins and minerals that support your immune system can help prevent illnesses and speed up your recovery when you do fall ill.
A healthy diet is key to boosting your immunity. The food you eat plays a big role in improving your overall health and well-being. In fact, it includes how well your immune system functions.
Since your immune system is what protects you from things like the flu, it’s important to nourish it properly.
The good news is that the best foods for your immune system are easily found at your local grocery store, and you don’t need to follow any extreme diets to benefit from them.
Best Foods to Boost Your Immune System
Let’s now look into some natural foods to boost your immune system.
1. Yogurt
Probiotics are beneficial bacteria in your gut that help with digestion. Instead of taking probiotic supplements, eating yogurt rich in probiotics can be helpful.
It does this by activating natural killer cells, which help stop diseases from spreading.
However, you must pick yogurt without a lot of added sugar. Plain yogurt is the best choice; you can make it tastier with cinnamon and fresh fruit. Plus, look for yogurts with less than 8 grams of sugar for a healthy option.
2. Citrus Fruits
Many people reach for vitamin C when they catch a cold because it strengthens the immune system.
Besides, many believe Vitamin C to be one of the best foods to boost your immune system when sick when sick. And that’s because it can boost the production of white blood cells, which are crucial in fighting infections.
Citrus fruits are a great source of vitamin C, and there are many types to choose from, making it easy to include this vitamin in your meals. Some popular citrus fruits are grapefruit, oranges, clementines, tangerines, lemons, and limes.
Your body doesn’t make vitamin C on its own, so it’s important to get enough of it every day. Most adults should aim for —
- 75 mg per day for women
- 90 mg per day for men
If you’re taking vitamin C supplements, try not to exceed 2,000 mg a day. It’s also worth noting that while vitamin C can help you get over a cold faster, there’s no proof yet that it works against COVID-19.
3. Chicken soup
A study by the University of Nebraska tested 13 types of chicken soup. They found that nearly all of them helped reduce inflammation, which is important because cold symptoms often come from inflammation in your airways.
Chicken releases an amino acid called cysteine when cooked, which is similar to a drug used for bronchitis. It might be why chicken soup is effective. Plus, the salty broth in the soup also helps thin mucus, like cough medicine does.
Adding spices like garlic and onions can make the soup even more beneficial for your immune system.
4. Ginger
Many people use ginger when they’re sick. It can help reduce inflammation, which might ease a sore throat and other inflammatory conditions. Ginger is also good for nausea.
Ginger is often found in sweet treats, but it also has a spicy kick due to gingerol, which is similar to capsaicin. It might also help with chronic pain and could lower cholesterol levels.
If you’re suffering from soreness, you might prefer applying essential oils for pain.
5. Fatty Fish
Among the top foods to boost your immune system, omega-3 fats can keep your immune system healthy. Fatty fish are a great source of these anti-inflammatory fats. Some options include —
- Albacore tuna
- Herring
- Mackerel
- Salmon
- Sardines
- Trout
However, some fish can contain mercury and other substances that might be harmful to unborn babies or young children. If you’re pregnant, breastfeeding, or have small children, it’s a good idea to talk to a doctor before adding these fish to your diet.
Other Natural Ways to Strengthen Your Immune System

Vaccines are crucial for protecting against illnesses like the flu, pneumonia, and COVID-19. Make sure you’re up to date with your vaccinations.
