Immune-Boosting Foods For A Healthy Body
‘The right raw materials can double or triple the protective power of the immune system,’ says Dr. Joel Fuhrman, the famous American doctor. This protective power can only come from a super healthy immune system.
The human body has a unique immune system. We cannot see it. But, it plays the most significant role. Its prime function is to protect the body’s overall health by keeping infections and diseases at bay. However, the immune system is not self-sustaining. It requires a delicate, harmonious balance of nutrition and lifestyle measures to function like clockwork.
Nutrition And Immunity: The Vital Link
Good nutrition is fundamental to safeguarding your immunity. Your dietary patterns and individual food habits are deeply associated with the immune response generated when there is an immune challenge.
Studies suggest that malnutrition can impair the production and activity of the immune cells and antibodies. Also, there’s bad news for people who love processed junk foods! Experts state that a diet consisting primarily of ultra-processed foods with low nutritional value can negatively impact the immune system. By nature, your digestive system is tuned to absorbing nutrients from dietary sources rather than supplements. However, when you feed your body with unhealthy supplementary diets, it may induce inflammation, weaken your immune system and promote disease development.
A good diet improves the immune system.
We need no stronger evidence to indicate that a healthy diet is a key to a responsive and strong immune system. A balanced diet comprises healthy foods like fruits, vegetables, legumes, lentils, lean protein, healthy fats, and whole grains.Oily processed foods and foods loaded with salt and sugar are certainly not a part of this list and hence are the ones you should steer clear off.
This is exactly why, for years, doctors have been advocating the goodness of fresh fruits and vegetables. Foods rich in Vitamin C are well-known for protecting the body and assisting in quick healing. Furthermore, foods like ginger, turmeric, lemongrass, and garlic are well-known for their ability to boost immunity and digestion since time immemorial.
To understand the connection between food and the immune system, we need to explore the topic in more detail.
Foods That Power Your Immune System
To eat is a necessity. To eat intelligently is an art. To build a robust immune system, you must choose foods that brim with vital nutrients. Nature has endowed us with many fruits, vegetables, and other food varieties that are undoubtedly the best natural immunity boosters.

Amla is also rich in antioxidants which help to manage oxidative stress and release the free radicals generated due to infections.
