Eat These 6 Superfoods for a Powerful, Healthy Immune System to Boost Your Defenses.

Effective immune system

Make sure to include these immune-boosting ingredients on your checklist.

Every year, immunity is crucial, but in recent years, it seems to have gained even more attention than before as a health issue. And when cold and flu season arrives (which lasts through the winter and occasionally even into early spring), it's always of particular interest. Fortunately, you may guard against colds and sick days by taking care of your immune system naturally through regular behaviours. Through diet and wise eating habits, you can strengthen your immunity for the rest of your life. It's not just helpful to eat foods and liquids that support the immune system; it's also simpler and more enjoyable than you may imagine.

Why Diet is Important for Immunity

Your food is a wonderful place to start if you're trying to improve immune function. 

The immune system and, ultimately, how well the body is able to defend itself against hazardous microorganisms are greatly influenced by nutrition. According to Gary E. Deng, MD, PhD, an integrative medicine specialist at Memorial Sloan Kettering Cancer Center, immune cells need specific nutrients to function effectively. According to a 2019 article in the journal Nutrients, these nutrients may function by initiating crucial physiological events, giving energy to immune cells, or fending off dangerous chemicals, to mention a few strategies.

Consume more protein, probiotics, and vegetables.

But exactly what does nutrition for immunity look like? Fortunately, according to the Institute of Nutrition and Dietetics, the optimal dietary strategy for a strong immune system should focus mainly on abundance of whole plants, most notably fruits and vegetables. It also correlates incredibly well with well-known nutrition advice. These plant-based meals provide fibre, vitamins, minerals, and antioxidants—all of which are crucial for supplying your immune system with energy. Foods with probiotics (those "good" bacteria for a healthy gut microbiota) and lean protein, which may be obtained from both animal and plant sources, are also necessary for an immunity-boosting diet.

Consume fewer packaged, processed, and highly refined meals.

Eat less of some meals in order to support your immune system. These less favourable diets typically consist of highly processed and refined foods, which are frequently devoid of nutrients that enhance immunity (e.g. natural fiber, phytochemicals, vitamins, and minerals). In addition to not providing what is required, when consumed in excess, they can actively weaken the immune system. According to registered dietitian Rhyan Geiger, RDN, they can induce oxidative stress and contribute to inflammation, causing your body to expend its antioxidant reserves to combat those processes rather than being prepared and able to combat the microscopic invaders that lead to illness.You can still indulge in ice cream and fries, so don't worry! But if you prioritise other foods in your diet more frequently than these delights, your body will appreciate it.

And, of course, improving immunity involves more than just what you eat and drink. Managing stress, getting adequate sleep (the average adult needs seven to eight hours per night), and maintaining an active lifestyle are all crucial behaviours.

Here are the top immune-boosting foods to choose from when cooking and shopping for groceries.

 

Types of food to Improve Healthy Immune System

• Grassy Leaves

Leafy greens like kale, spinach, Swiss chard, and arugula are some of the finest meals to eat frequently since they boost both heart health and cognitive function. In particular, vitamin C and vitamin K, which [are needed for] fostering a strong immune system, are abundant in leafy greens, according to Geiger. Beta-carotene and folate, or vitamin B9, are other minerals in leafy greens that support the immune system. Aim for at least two cups of leafy greens every day to get your fill, she advises. And keep in mind that you are by no means restricted to salads: Make a hydrating green smoothie or incorporate some greens into your favourite soups, stews, omelettes, pasta dishes, and grain bowls.

• Probiotic Food

Probiotic foods like tempeh, yoghurt, kefir, kimchi, and sauerkraut are the stars when it comes to gut health. Additionally, these probiotic-rich options are multifunctional superfoods because gut health is linked to immunity. According to Dr. Deng, the "good" bacteria in probiotic meals support the gut lining's immune cells and help food's germs break down nutrients that would otherwise not be available to the body.This guarantees that your immune system receives the nutrition it requires to perform at its peak. Dr. Deng advises incorporating probiotic items into your diet two to three times a week for the most immune-supporting effects. Start your day with Greek yoghurt topped with chopped nuts and berries, have a pickle as a snack, or add sauerkraut to your fish tacos.

• Great orange fruits

Vitamin C is abundant in citrus fruits like oranges and grapefruit. According to Geiger, this vitamin is crucial for excellent immunological performance since it encourages the creation of white blood cells that fight sickness (i.e., immune cells). Citrus fruits can be enjoyed by adding them to water, dressing salads with them, or blending them into fruit smoothies, she advises.

• Berries

Berries including strawberries, blueberries, and raspberries are among the best foods for boosting the immune system. Berries are rich in antioxidants, which Dr. Deng claims helps shield healthy cells from potentially harmful chemicals. Additionally, berries provide fibre, which supports the "good" bacteria in the digestive tract, as well as vitamin C, a necessary immunity factor (particularly in strawberries). Aim for two half-cup servings of berries per week, which is simple to do with delectable foods like smoothie bowls and berry baked oatmeal. Or you can simply eat them straight from the carton in the refrigerator by the handful.

• Healthy Protein

Although our plant-based diets are a good source of vitamins and antioxidants, protein is just as important for immunological health. Protein "helps" the body generate antibodies, heal muscles and tissues, and boost the synthesis of amino acids necessary for immunological function, according to Geiger. Choose lean proteins, which are low in saturated fat, for the healthiest alternative. (When ingested in large quantities, this type of fat might increase your LDL or "bad" cholesterol.) Tofu, beans, lentils, skinless chicken or turkey, and white-fleshed fish like tilapia are a few examples of low protein  

• Flavored (Green ) teas

You can also drink your way to a stronger immune system. Green tea is a necessity in your tea cabinet because it is so delightfully reviving and earthy. Geiger notes that epigallocatechin gallate is a plant molecule found in green tea, which is one of many antioxidants. This substance "may aid in lowering bodily inflammation and enhancing function." Green tea can be consumed hot, chilled, or blended into a smoothie for a delightful twist.
