Nutrition is important for a healthy immune system

Our immune system is one of the most effective forms of defense against viruses. Although we know the benefits of a healthy immune system, how to strengthen the body’s immunity is not simple.

There’s still a lot about the immune system that researchers are still working to better understand, but we do know there’s a strong link between nutrition and immune system health. Join Dr. David Heber, President, Herbalife Nutrition Research Institute to learn more about this exciting topic.

How does nutrition affect the body’s immune system?

To understand how nutrition and diet affect the immune system, we need to delve deeper into the biological mechanisms that turn our genes on and off.

While we are all 99.9% genetically similar, the combination of different genes that are turned on and off makes us different and unique. This is why some of us have red hair and others have black hair, or why some people have darker or lighter skin.

What we eat, where we live, how much we sleep, exercise, and even who we live with, all trigger chemical reactions that can alter the state of our health. In addition, the microbiome in the human body, which is the microorganisms that help us fight the invasion of bacteria and viruses, break down food to convert it into nutrients and energy. intake, synthesize important vitamins and boost our immune health.

The largest part of immune system health – about 70% – lies in the digestive system, which controls how much food you eat and how your body uses nutrients. Therefore, it is important that we have a balanced diet of the right vitamins, minerals and nutrients while maintaining a healthy lifestyle. This does not mean simply altering intake for one or two nutrients but involves balancing the entire diet to ensure that optimal nutrient intake is available at the cellular level.

4 groups of essential nutrients to help strengthen the immune system

1. Protein

Also known as the body’s basic building blocks, proteins enable the body to produce the antibodies it needs to fight viral and bacterial invasion. To ensure that we get enough protein in our diet, we can eat healthier protein-rich foods like fish, poultry, lean meats, soy foods, and dairy products. low fat.

2. Vitamins and Phytonutrients

Vitamins A and C, as well as phytonutrients, are important for supporting immune system health. Vitamin C is one of the most powerful immune-boosting active ingredients, Vitamin C stimulates our body to produce antibodies to fight diseases. Because the body cannot synthesize or store it on its own, we need to get enough Vitamin C in our daily diet. Vitamin A supports healthy skin and tissues in the digestive and respiratory systems.

Phytonutrients – phytonutrients, found in vegetables and fruits, can help reduce oxidative stress in our bodies, which underlies our ability to fight disease. Certain phytonutrients have been shown to reduce the risk of cancer and cardiovascular diseases, fight inflammation, lower blood pressure, and boost immune system health.

3. Probiotics and prebiotics

The digestive system plays a very important role in supporting immune function. The intestinal tract is the main route of contact with the external environment; and is also the place where the intestinal microflora (bacterial population) functions to support digestion and absorption of nutrients.

Gut bacteria will aid in weight control, improve digestive function, help healthy skin full of vitality and most importantly, support the body’s resistance, although the Research results in these areas have not been conclusive or universally applicable.

Studies have shown that probiotics, also known as probiotics, help maintain a healthy digestive system, and prebiotics are fibers that can’t be digested, but are a food source for gut bacteria.

4. Omega-3 Fatty Acids

Omega-3 fatty acids, such as DHA and EPA, are good and essential fats that can be found in foods like chia seeds and supplements like fish oil. Omega-3 fatty acids can enhance the function of cells in the immune system, so they play an important role in both mechanisms, including the innate immunity mechanism that helps prevent diseases from entering the body. and adaptive immune mechanisms against infection.
