A healthy and balanced vegetarian diet can help increase your body's immunity. Immunity plays a vital role in protecting your body from foreign particles and fighting off pathogens, which are the viruses, bacteria, and other foreign bodies that cause infection or disease. While vegetarian diets may not include all essential nutrients, they can still provide the body with the nutrients the immune system needs to function correctly. A vegetarian diet can help boost immunity by providing the body with vitamins, minerals, and antioxidants, which help fight infections and diseases.

Include vitamin C-rich foods like citrus fruits, broccoli, and strawberries
A vegetarian diet can be a great way to boost your body's immunity. It is important to eat a balanced diet with a variety of fruits and vegetables to ensure your body gets all the nutrients it needs to function properly. One key nutrient to focus on is vitamin C, a powerful antioxidant that helps build your immune system by increasing the production of white blood cells, which are essential for fighting off infections.
Citrus fruits, such as oranges, grapefruits, tangerines, and lemons, are an excellent source of vitamin C. Starting your day with a glass of freshly squeezed orange juice or adding a squeeze of lemon to your meals can provide a quick boost of vitamin C. These fruits are not only packed with vitamin C but also offer other essential nutrients like vitamin A and flavonoids, which have anti-inflammatory properties and help your body fight off viruses and toxins.
Broccoli is another excellent source of vitamin C for vegetarians. It is a superfood that contains not only high levels of vitamin C but also antioxidants like sulforaphane, which help reduce inflammation and protect the body against acute and chronic disorders. Broccoli is a versatile vegetable that can be enjoyed steamed, roasted, or even raw, making it easy to incorporate into your diet.
Strawberries are a delicious and nutritious addition to your diet, packed with vitamin C and other essential nutrients. They are an excellent choice for a sweet treat or a refreshing snack, boosting your vitamin C intake and providing your body with powerful antioxidants.
In addition to these vitamin C-rich foods, it is important to maintain a balanced diet with a variety of other fruits, vegetables, whole grains, and nuts to ensure your body receives all the necessary nutrients for a strong immune system. Remember, while diet plays a crucial role in boosting immunity, other factors such as exercise, stress management, and maintaining a healthy weight are also important to consider for optimal immune health.

Consume vitamin D through cheese, egg yolk, or supplements
Vitamin D is an essential nutrient for optimal health, but it can be challenging for vegetarians to obtain sufficient amounts through dietary means alone. This is because vitamin D is predominantly found in animal products, including fish, eggs, and beef liver. As such, vegetarians may need to be mindful about including vitamin D in their diet to ensure their immune system remains robust.
Cheese is a natural source of vitamin D, although the amount present varies depending on the type and manufacturing process. Soft cheeses, for example, contain almost no vitamin D. Some cheeses are fortified with vitamin D, so checking the label or ingredient list can help identify these options.
Egg yolks are another good source of vitamin D for vegetarians. The vitamin D content in eggs can be increased by adding it to the feed of hens, exposing the hens to UVB light, or exposing the egg yolk directly to UVB light. Choosing eggs from chickens raised outside or marketed as high in vitamin D can help meet your daily vitamin D requirements.
For vegetarians who may not get enough vitamin D from dietary sources, supplements can be a convenient option. Various vegan vitamin D3 supplements are available, derived from lichen and providing up to 1000 IU of vitamin D per tablet. These supplements are free of common allergens and animal products, making them suitable for vegetarians and vegans.

Get vitamin B12 through animal products or supplements
Vitamin B12 is a key nutrient that the body needs for many essential functions. It is naturally found in animal products, including meat, poultry, (shell)fish, eggs, milk, and other dairy products. Organ meats, such as liver and kidneys, are very high in vitamin B12. Clams also contain large amounts of vitamin B12. Vitamin B12 is generally not present in plant foods, but vegetarians can get their vitamin B12 from eggs and dairy products. Additionally, some fortified foods, such as breakfast cereals and nutritional yeast, are good sources of vitamin B12 for those on a vegetarian or vegan diet.
Vitamin B12 is essential for keeping your nerves healthy and supporting the production of DNA and red blood cells, as well as maintaining typical brain function. The Reference Daily Intake (RDI) is about 2.4 micrograms (mc) but is slightly higher for those who are pregnant or nursing. If you are a vegan, you are at risk of vitamin B12 deficiency, as per the Academy of Nutrition and Dietetics. This deficiency can lead to blindness, muscle weakness, anaemia, numbness, and tingling.
If you are unable to get enough vitamin B12 through your diet, you can take dietary supplements. Vitamin B12 supplements are available in liquid form, and injections may be used to treat vitamin B12 deficiency in people with pernicious anaemia.

Eat iron-rich foods like lentils, beans, and spinach to prevent iron deficiency
Vegetarian diets are often lacking in iron, which is essential for maintaining a healthy immune system. Iron is of two types: heme iron, derived from hemoglobin, and non-heme iron, derived from plant sources. Heme iron is found in meat, fish, and poultry, whereas non-heme iron is found in plant-based sources like lentils, beans, and spinach.
Lentils, beans, and spinach are excellent sources of non-heme iron, which is less easily absorbed by the body than heme iron. However, this can be mitigated by consuming vitamin C-rich foods at the same time, which aids in the absorption of non-heme iron. For example, a squeeze of lemon juice can enhance the benefits of spinach, a well-known iron-rich food thanks to Popeye. Tomatoes, red, yellow, and orange peppers, and strawberries are other vitamin C-rich foods that can help increase iron absorption.
In addition to lentils, beans, and spinach, other plant-based sources of iron include peas, chickpeas, nuts, seeds, and quinoa. Fortified whole-grain, wheat, oat, and bran cereals are also good sources of iron. To maximize iron absorption from plant-based sources, it is recommended to consume cooked vegetables and combine grains, seeds, and pulses with vitamin C-rich foods.
Iron deficiency can lead to a weaker immune system, making individuals more susceptible to colds and infections. Therefore, it is important to ensure adequate iron intake, especially for vegetarians who rely solely on plant-based sources of iron. By including these iron-rich foods in a vegetarian diet, individuals can help prevent iron deficiency and maintain a strong immune system.

Drink green tea, kefir, or water to stay hydrated and support immunity
Staying hydrated is essential for supporting your immunity, and there are several drinks that can help you do this while also providing a boost to your immune system.
Green tea is a powerful drink with a long history; it has been used as a defense against disease for thousands of years. It is made from the leaves of the Camellia sinensis plant and contains many immune-boosting compounds, including epigallocatechin gallate (EGCG), which has been studied for its ability to enhance immunity and alleviate inflammation. EGCG can also alter the activity of specific proteins, which may help to block viruses such as the flu from replicating. Catechins, another compound in green tea, are believed to have antiviral properties and could offer protection against illness and infection.
Kefir is another drink that may support immunity. It is a versatile fermented beverage that has been linked to slowing Alzheimer's disease. While more studies are needed, kefir has been associated with higher levels of antioxidant activity and reduced oxidative damage.
Water is, of course, essential for hydration, and herbal teas can be a great way to add variety if you find plain water boring. You can also try adding fruit or herbs to your water for flavor.
It is worth noting that a well-rounded vegetarian diet can provide all the necessary nutrients to maintain a healthy immune system. However, it is important to ensure you are consuming a balanced diet with all the required vitamins and minerals, as a vegetarian diet may lack certain nutrients such as Vitamin D and B12, and sufficient iron intake.
