The most effective food items to increase immunity include citrus fruits like grapefruits and oranges, red bell peppers, garlic, ginger, and probiotic-rich yogurt. These foods provide essential Vitamin C and antioxidants that activate your white blood cells to fight off infections faster.
I used to catch every cold that went around the office. It was frustrating.
I realized I couldn’t just take a pill to fix it. I had to change what I ate.
If you are looking for food items to increase immunity, you don’t need expensive supplements. You just need to stock your fridge with the right ingredients.
Here is exactly what you should eat to stay healthy.
What are the best food items to increase immunity?
Your body uses nutrients as fuel to fight germs. If you feed it junk, it fights poorly. Here are the heavy hitters.
Citrus Fruits
Most people turn to Vitamin C after they’ve caught a cold. That is true because it helps build up your immune system.
Body doesn’t produce or store it. You need daily Vitamin C for continued health.
Key fruits include:
- Grapefruit
- Oranges
- Tangerines
- Lemons
- Limes
Red Bell Peppers
Think citrus has the most Vitamin C? Think again.
Ounce for ounce, red bell peppers contain almost 3 times as much Vitamin C as a Florida orange. They are also a rich source of beta carotene.
This keeps your eyes and skin healthy while fighting off flu viruses.
Broccoli
Broccoli is supercharged with vitamins and minerals. Packed with vitamins A, C, and E, as well as fiber and many other antioxidants, it is one of the healthiest vegetables you can put on your plate.
Pro Tip: The key to keeping its power intact is to cook it as little as possible. Steaming is best.
Garlic
Garlic is found in almost every cuisine in the world. It adds a little zing to food and it’s a must-have for your health.
It helps lower blood pressure. But for immunity, garlic’s immune-boosting properties come from a heavy concentration of sulfur-containing compounds, such as allicin.
Yogurt
Look for yogurts that have “live and active cultures” printed on the label, like Greek yogurt. These cultures may stimulate your immune system to help fight diseases.
Try to get plain yogurts rather than the kind that are flavored and loaded with sugar. You can sweeten plain yogurt yourself with healthy fruits and a drizzle of honey.
What foods help against cold and cough?
When you feel that scratch in your throat, you need specific food to increase immunity against cold and cough. These ingredients reduce inflammation.
Ginger
I turn to ginger immediately when I feel sick.
Ginger may help decrease inflammation, which can help reduce a sore throat and inflammatory illnesses. It may also help with nausea.
Spinach
Spinach made our list not just because it’s rich in Vitamin C. It’s also packed with numerous antioxidants and beta carotene.
This increases the infection-fighting ability of our immune systems. Similar to broccoli, spinach is healthiest when it is cooked as little as possible so that it retains its nutrients.
Almonds
When it comes to preventing and fighting off colds, Vitamin E tends to take a backseat to Vitamin C. However, this powerful antioxidant is key to a healthy immune system.
It’s a fat-soluble vitamin, which means it requires the presence of fat to be absorbed properly. Nuts, such as almonds, are packed with the vitamin and also have healthy fats.
What can I drink to boost my immune system?
Staying hydrated is half the battle. But water isn’t your only option. If you are asking, “What can I drink to boost my immune system?” here are the best options.
Green Tea
Both green and black teas are packed with flavonoids, a type of antioxidant. Where green tea really excels is in its levels of epigallocatechin gallate (EGCG).
EGCG has been shown to enhance immune function.
Turmeric Milk (Golden Milk)
This is a staple in many households for a reason. Turmeric acts as an anti-inflammatory.
Curcumin, the compound in turmeric, creates a modest improvement in a person’s immune response. Mixing it with warm milk and black pepper helps your body absorb it.
What is the best morning drink to boost immune system?
Starting your day right sets the tone. A great morning drink to boost immune system function is a warm Lemon and Honey water.
Here is why I drink this every day:
- Hydration: It wakes up your organs.
- Vitamin C: The lemon provides a quick hit of vitamins.
- Antimicrobial: Honey coats the throat and fights bacteria.
Simply squeeze half a lemon into warm water and stir in a teaspoon of raw honey.
Real-World Observation: What I’ve Learned
In my ten years of tracking health trends and my own diet, I have noticed one thing. Consistency beats intensity.
You cannot eat five oranges in one day and expect to be immune for a month.
I once tried a “superfood cram” where I ate only kale and garlic for three days before a trip. I still got sick.
Why? Because your immune system is a marathon runner, not a sprinter.
The Data: Recent studies suggest that 70% of your immune system lives in your gut. If you ignore your gut health (yogurt, fiber) and just take Vitamin C pills, you are missing the biggest piece of the puzzle.
If you want to add garlic to your diet as one of the food items to increase immunity, then you can use garlic while cooking your food items, and secondly, you can add garlic soup to your diet. These can help you boost your immunity effectively.
