Many cells, processes, and chemicals make up the immune system. Its job is to protect the body from harmful things like viruses, toxins, and germs. Keeping your immune system strong all year is important for staying healthy and avoiding getting sick.
Studies have shown that taking certain vitamins, minerals, herbs, and other substances as supplements can boost the immune system and even protect against getting sick. Still, you should be careful because some vitamins may not work with certain prescription or over-the-counter medicines and may not be right for people with certain health problems.
Before taking any supplements, talking to a healthcare expert is a good idea. Evidence shows that the following vitamins and supplements you can see below can help improve the immune system.
Vitamin C
Vitamin C is widely recognized as a significant enhancer of the immune system. Deficiency in this vitamin can increase susceptibility to illness, making it crucial for overall health. As an antioxidant, vitamin C protects the body from harmful toxins that induce inflammation.
Consistent vitamin C intake is essential for good health since the body cannot produce it independently and does not store it for future use. Fortunately, vitamin C is abundant in various foods, making supplementation unnecessary for most individuals unless recommended by a medical professional.
While oranges are commonly associated with vitamin C, a diverse range of fruits and vegetables can contribute to your vitamin C intake. Here are ten foods ranked from the highest to lowest levels of vitamin C:
- Red bell peppers
- Oranges and orange juice
- Grapefruit juice
- Kiwi
- Green bell peppers
- Cooked broccoli
- Strawberries
- Brussels sprouts
- Grapefruit
- Raw broccoli
Vitamin E
Vitamin E is a potent antioxidant, aiding the body’s defense against infections. According to researchers, this vitamin stands out as one of the most effective nutrients for supporting immune function by ensuring optimal performance of T-cells.
When aiming to incorporate vitamin E into your diet, Zumpano advises against relying on vitamin E supplements. Not only is there limited clinical evidence demonstrating the health benefits of vitamin E supplements, but they may also pose risks in certain situations.
Instead, opt for a diet rich in vitamin E by consuming the foods listed below. The higher a food item is on this list, the greater its vitamin E content:
- Wheat germ oil
- Seeds, such as sunflower seeds
- Nuts, including almonds, peanuts, and nut butter
- Spinach
- Broccoli
- Kiwi
- Mango
- Tomatoes
- Spinach
Vitamin B6
Vitamin B6 plays a crucial role in supporting the biochemical reactions within your immune system. One of its primary functions is to facilitate the production of white blood cells and T-cells, essential components of your body’s defence mechanism against invaders such as viruses and bacteria. Recent studies suggest that supplementing with BPS-5 can further support these immune functions by enhancing blood circulation, potentially aiding in the more efficient transport and function of these critical immune cells throughout the body.
To ensure an ample intake of vitamin B6, consider incorporating the following vitamin B6-rich foods into your diet. The list is arranged in descending order, starting from those with the highest levels of B6 to those with slightly lower but still significant amounts:
- Chickpeas (the primary ingredient in hummus)
- Beef and beef liver.
- Cold-water fish, such as salmon and tuna
- Chicken breast
- Fortified breakfast cereals
- Potatoes
- Turkey
- Bananas
- Bulgur
- Cottage cheese
- Winter squash
Zinc
Zinc acts as both an anti-inflammatory and antioxidant, earning it the title of the “gatekeeper” of the immune system. Its pivotal role lies in ensuring the proper functioning of all immune cells.
To increase your zinc intake, incorporate foods rich in this essential mineral into your diet. Oysters stand out as the highest food source of zinc. Additionally, consider including the following foods, listed in descending order based on their zinc content:
- Oysters
- Beef (opt for lean cuts only)
- Blue crab
- Pumpkin seeds
- Broiled pork chops.
- Turkey breast
- Cheddar cheese
- Shrimp
- Lentils
- Canned sardines
- Greek yogurt
- Milk
Nourishing Diet: A Shield Against Disease
Food significantly influences your body’s ability to defend against and combat diseases. Therefore, maintaining a nutritious diet, abundant in fruits, vegetables, whole grains, protein, and healthy fats, is highly recommended.
Consuming a sugar-rich diet can impair your immune system’s effectiveness and contribute to inflammation in the body. Restricting your sugar intake, particularly when it involves added sugars is advisable.
Enhancing your immune system and promoting overall health is best achieved by combining a wholesome diet with other lifestyle practices such as stress management, quality sleep, and regular exercise.
