In the UK, the number of people following a vegetarian or plant-based diet is growing rapidly. People choose a vegetarian diet for cultural or health reasons, and studies show that it has many health benefits. One is that it boosts immunity. A large amount of foods in a vegetarian diet, including fruits, vegetables and beans, are considered to be beneficial to health. Vegetarian foods include fruits, vegetables and whole grains, but also include dairy products and eggs. Vegetarians follow a variety of dietary patterns, from vegan to dairy and egg. Research suggests that a balanced vegetarian diet may be good for our immune system and the body's associated responses.
Our bodies face daily challenges, such as fighting off viruses. The immune system is "on" in response to these attacks. A healthy immune system prevents us from getting sick. A healthy immune system can be maintained by many lifestyle factors, including adequate sleep, a healthy weight and regular physical activity. It's also influenced by what you eat. Vegetarians generally have low levels of white blood cells, our natural defense cells. Low white blood cell levels affect the body's ability to fight infection. However, having the right amount of white blood cells in a healthy range may reduce your risk of developing the disease.
In addition to boosting immunity, vegetarianism may also help our bodies engage in a related process called inflammation. Vegetarian diets have been shown to prevent inflammation caused by antioxidants in foods. Inflammation occurs when the body releases cells to attack pathogens or respond to damage. It can cause redness in one part of the body or the release of certain chemicals in the body. Inflammation is a protective measure the body USES to stay healthy.

Long-term vegetarians have a lower risk of type 2 diabetes, heart disease and even some cancers than non-vegetarians. These chronic diseases are associated with increased inflammation in the body. This is indicated by elevated levels of creative protein in the blood, which is a signal of systemic inflammation. In the long term, nutrients found in vegetarian diets have been shown to improve inflammation levels. Of course, being vegetarian may not be for everyone. An improperly balanced diet increases the risk of iron, zinc, and vitamin B12 deficiency. This is detrimental to overall health, and some people may need to take greater risks because of their own increased nutritional needs. Therefore, vegetarian diet should be used under the guidance of a dietitian to minimize the risk. But whether you're a vegetarian or not, it's worth eating more plant-based foods.
