If you’re struggling with colds and flu this season, a plant-based diet may be able to help strengthen your immune system and prevent illness. Here’s how it works and some immunity-boosting plant-based foods to add to your diet!

Fruits and vegetables are immunity superheroes, with lots of vitamin C and antioxidants. Nuts and seeds are also good sources of vitamins B-6, magnesium, phosphorous and selenium, which help regulate immune function and prevent infection.

How Does a Plant-Based Diet Impact the Immune System?

Your immune system is designed to protect your body against germs, bacteria, viruses and other environmental toxins. But it can be stymied by many things, like smoking, chronic stress, alcohol abuse, a diet high in sugars and unhealthy fats, lack of sleep and exercise, vitamin D deficiency and more.

A healthy immune system is important to reducing your risk of cancer and other diseases. It’s also critical for preventing inflammation, which can damage your cells and tissues and lead to disease.

Plant-based foods provide essential nutrients that support a strong immune system. Some of these nutrients include iron, zinc, B vitamins and calcium. Vegetables, legumes, nuts and seeds are all excellent sources of these immune-boosting nutrients.

The plant-based diet also influences the gut microbiome, boosting bacterial diversity and potentially reducing inflammation. In particular, the fiber in plant foods provides prebiotics for the bacteria living there.

There are some studies that have found that elderly vegetarians who have eaten a plant-based diet most of their lives may experience enhanced immune function, compared to those who eat meat or fish. However, further research is needed to assess this hypothesis in more individuals and longer-term periods.

What Are Some Immune-Boosting Plant-Based Foods?

Choosing a healthy, plant-based diet is one of the best ways to improve your immune system. A plant-based diet is high in fruits, vegetables, whole grains, and legumes, which are packed with nutrients that help strengthen your immune system, fight infections, and prevent illness.

Fruits and vegetables are also good sources of vitamin C, which plays an important role in the body's natural defenses against infection. They're also full of antioxidants and phytonutrients, which can help protect your body against disease.

Other foods that are known to boost your immune system include garlic and turmeric, both of which are loaded with compounds called allicin and curcumin, respectively. Both have been found to activate the immune system and reduce inflammation.

Eating a variety of colorful fruits and vegetables is also a great way to strengthen your immune system. Eat at least two servings of fruits and 8-10 servings of veggies daily.

Aside from these essential nutrients, a plant-based diet is rich in probiotics, which help boost your immune system and fight off illnesses. Foods that contain probiotics include dairy products, kombucha, sauerkraut, and fermented pickles.

How Can a Plant-Based Diet Help Me Strengthen My Immune System and Prevent Illness?

A plant-based diet is rich in immune-boosting nutrients and phytochemicals. Antioxidants, such as lycopene, and other vitamins and minerals, help to reduce chronic inflammation, which is one of the leading causes of many chronic diseases.

A diet that is high in fruits, vegetables, whole grains, beans, seeds and nuts also helps you to get all the protein you need for a strong and healthy immune system. In fact, a 14-year Harvard study found that people who ate the most fruits and vegetables had a 30 percent lower risk of heart disease.

Vegetables, whole grains and beans are all good sources of a wide range of phytochemicals that can help keep your immune system healthy and functioning properly. Those phytochemicals include vitamin C and E, selenium, lycopene and beta-carotene.

To boost your immunity, make sure you are getting enough of the vitamins and minerals that your body needs, especially vitamin D, B12, iron and omega-3 fatty acids. These can be difficult to find in whole foods, so consider supplements and look for fortified food options such as plant milks, spreads and cereals.

Start with a few small changes, such as adding more fruits and veggies to your meals or trying a new meat-free recipe every week. These small tweaks can have a big impact on your health, and can help you feel better than ever before!

Vegetarian hamburgers made with black beans or quinoa are also comparable to beef burgers. Additionally, coconut bacon strips or eggplant bacon bits; tofu mayo; veggie hot dogs made with seasoned textured soy protein; and faux chicken strips from wheat gluten offer tasty alternatives that do not require animal products. It is possible to modify recipes to use vegetables, grains, beans and seeds as a source of nutrients and flavor. Steaming, roasting or grilling are all great ways to enjoy plantbased meals without compromising savoriness.

Is it possible to sustain a plant-based diet?

For their environmental and health benefits, plant-based diets have been growing in popularity. Plant-based food is generally more sustainable than food derived from animal resources. This is because it produces less greenhouse gases and causes less pollution. A plant-based diet also takes up fewer resources as plants are typically grown with fewer inputs than animal products. Furthermore, animals raised in commercial farms often consume large amounts of water and land as well as fossil fuels. As some environmental effects of livestock production have been linked to global warming, reducing consumption of these foods through introducing more plant-based meals into one's weekly rotation could help reduce an individual's carbon footprint and support healthier, more eco-friendly practices.

What other protein sources can I use instead of meat?

Protein is an essential component to a healthy diet. It's available in animal- or plant-based sources. The most common plant-based sources of protein include legumes and nuts, seeds, grains, tofu and tempeh, beans and lentils, seitan, wheat gluten, and hemp seeds. A high level of antioxidants can be found in many vegetables and fruits which can offer anti-inflammatory benefits. Almond or oat milk are great alternatives to cow's milk. They also contain proteins so they can be used as dairy substitutes. Alternatives like pumpkin seeds, nutritional yeast, and other plant-based milks can provide cheesy flavors to dishes while also offering more micronutrients. For extra nutrition, there are many vegan protein powders available that can be added to smoothies and shakes.

Is a plant-based diet harmful?

A lot of people have found health benefits in adopting a plantbased diet. However it is possible to become sick if you don't manage your diet properly or consult a doctor. People transitioning to a plant-based lifestyle should carefully consider proper vitamin and mineral intake, such as B12, iron, zinc, and Omega 3 fatty acids. A diet lacking in these essential nutrients can lead to health issues and deficiencies. A vegan/plant-based lifestyle can also mean avoiding dairy and eggs which could lead to muscle loss. Plant-based diets should be adjusted to meet individual needs. If necessary, a nutritionist or doctor can be consulted.

Are you able to get enough protein with a plant-based lifestyle?

Yes, you can get enough proteins from a plant-based diet. For muscle building and health, you can use amino acids in legumes, seeds, legumes, and nuts. Tofu, as well as other soy products, has all 9 essential amino compounds that the body cannot create and must get from food. Vegetables like spinach, broccoli, or kale are also high in protein and can provide the amount of protein required for adequate nutrition when combined with legumes and grains. Plant-based proteins tend to have lower levels in saturated fats than animal protein and can be used to support long-term satiety. Additional nutrients such as omega-3 fatty acids can be added to plant-based diets through the addition of flaxseeds (chia seeds), walnuts, and hemp seeds.
