Immune Function: Facts You Need To Know For Lifelong Health

Immune Function

Immune function is dependent upon a balance between the free radical and antioxidant status of the individual. In healthy adults, exposure to high levels of oxidants is associated with a reduction in clinically relevant immune responses; exposure to low levels of dietary antioxidants also reduces immune responses.

As everyone in the world comes to grips with the realities of the COVID-19 pandemic I thought it would be a good time for us to remind ourselves of how important our immune system is and the immune function it provides, how much we take it for granted and how much it is dependent upon our ability to provide it with the nutrition it needs to deliver its highest level of protection. This is a message the SAB has been delivering for decades, but it has never been more appropriate than right now.COVID19

Science has proven that our immune function is nutrition dependent. That the absence or presence of important nutritional components has a profound impact on our immune capacity, its ability to protect us and thus our survival. When nutrition is poor, our immune systems are compromised, but when nutrition is good our immune systems are good. When our nutrition is great our immune systems can reach their highest potential to protect us from the widest array of challenges.nutrition

It’s never too late to work on maximising your immune system’s ability to protect you! Focusing on immune-boosting and immune balancing nutrition is something everyone can do. It’s not a question of if it is possible, it’s only a question of how strongly we all embrace it.

Without going too deeply into this highly complex and critical topic there are a few key points about nutrition and immune function that I want to reaffirm. First a few fundamental definitions…

Nutrition – is the nourishment or energy received from the foods and nutrients delivered by the diet to support and promote health and growth.

Malnutrition – is overconsumption or under consumption of nourishment or energy needed to support health and growth and resulting in a negative health impact.

For the purpose of this message I will focus on the impact of undernutrition, and the dietary deficiencies and inadequacies it represents, on immune function. Undernutrition is a form of malnutrition where intake fails to meet needs. Undernutrition results in immune dysfunction or compromise.

 

Why getting essential vitamin and minerals are so important

vitamin and mineralsThe relationship between nutrition and immune function has been well and clearly established by decades of scientific investigation. Undernutrition, or deficiency of key essential vitamins and minerals, is known to result in immune dysfunction or compromise. Immune-compromising vitamin and mineral deficiencies include vitamins A, D, C, E, B6, and B12, folic acid, zinc, iron, copper, and selenium. This is not a new idea, but I felt that an article published in the January 2020 issue of the journal Nutrients, titled “A Review of Micronutrients and the Immune System-Working in Harmony to Reduce the Risk of Infection” was timely, and strongly reaffirms this well-known reality. They state, “Adequate amounts are essential to ensure proper function of physical barriers and immune cells; however, daily micronutrient intakes necessary to support immune function may be higher than current recommended dietary allowances.”

The presence or absence of these immune-centric vitamins and minerals “modulates” our immune capability and strength. Simply stated, that means when they are low in the diet, immune power is compromised or suppressed. Conversely, when they are abundant in the diet immune power is elevated. Sadly, most people are deficient in one or more of these key essential nutrients.

 

The vital roles of whole-food nutrients

In addition to these Immune-centric vitamins and minerals, there is a great and growing body of evidence that other whole-food nutrients play critical roles in immune function. Like the vitamins and minerals above, their presence or absence modulates our immune capacity.whole-food nutrients

Carotenoids are a great example. These lipid-soluble, colourful components that make carrots orange or peppers red are well documented in scientific literature to be immune modulators. Remember, modulation means when carotenoids are low in the diet immune capacity is suppressed. Conversely, when they are abundant in the diet immune capacity is elevated. This immune-modulating effect has been shown in powerful clinical studies, including those done on NeoLife Carotenoid Complex and published in the American Journal of Clinical Nutrition.Carotenoid Complex - 90 Capsules

Polyphenols, which include Flavonoids, are another example of immune-modulating whole-food nutrients. Amongst a growing body of evidence of immunological benefit, a 2018 review article in the Journal of Immunology Research titled “Regulation of Immune Function by Polyphenols” points out in their opening comments that “Polyphenols promote immunity to foreign pathogens via various pathways. Different immune cells express multiple types of polyphenol receptors that recognise and allow cellular uptake of polyphenols, which subsequently activate signalling pathways to initiate an immune response.”

The role of omega-3 fatty acids in immune function has not gotten the same level of attention as other nutrient groups. They are known more for their heart-healthy, anti-inflammatory benefits. NeoLife research first touched on omega-3’s and immune function in our 2007 clinical trial that showed inflammatory balancing benefits. That was followed by evidence showing the promotion of biomarkers of inflammation resolution and healing. More recently, evidence has emerged regarding their critical roles as signalling molecules, helping to coordinate and regulate the activity of immune cells.Omega-3 Salmon Oil Plus

There is a great deal more to the importance of nutrition for optimal health and immunity. Thousands of articles and books have been written on the topic, but for the purpose of this message, I will leave it here for now.

If the above information sounds like what we’ve been saying about core nutritional products like Pro Vitality it shouldn’t be surprising. The importance of the wide array of nutrients it can contribute to lifelong health and vitality is an irrefutable reality of human biochemistry. As always, we strongly advise making these whole-foods the dominant components of your diet, for all the many benefits they provide, including immune strength. It remains however that most people are unable to get that done.

Pro Vitality is a perfect choice to help bridge those immune compromising nutritional gaps.
