5 Modifiable Lifestyle Factors Crucial To Your Immune Function

Our understanding of how food affects the immune system is constantly expanding and evolving. These five lifestyle factors are crucial and within your control while we take care of ourselves during immune challenges.


You may not be aware that 80% of the body’s immune system resides in your gut, and what you feed this massive microbiome really matters. First, eat high fiber colorful foods every day. Second, consume fermented foods. Third, consume probiotic and prebiotic organisms. These are my favorite gut nourishing foods.

For the health of the immune system, this is crucial. First, see above about taking care of the gut! Second, include omega-3 fats by using EPA and DHA. Third, stop eating inflammatory foods right now. Fourth, increase your daily intake of antioxidants from omega-3 fats, herbs, vitamins, and nutrients.

Revive and Rehydrate Antioxidant Support: loaded with antioxidants that can neutralize the five most important free radical forms.

Omega-3 fish oil: supplies a concentrated quantity of the important omega-3 fatty acids to support a healthy inflammatory response.


High blood sugar levels cause inflammation and weaken many immune processes, including immune system defenses. Maintaining normal blood sugar levels throughout the day is key to supporting the immune system. First, limit the sugar and processed foods. Second, include high-fiber foods, fats and protein at every meal. Third, exercise.

Taking care of yourself has never been more important!

Stressing out is on of the body’s biggest immune zappers. Worrying about the stock market and focusing on the uncertainties of the future can raise cortisol levels, which can negatively impact immune function. Toss in feelings of isolation and loneliness and it’s a triple whammy against your immune system.

  • Stress depletes specific nutrients the body needs to adapt.

Adaptogens are also amazing plants that promote a healthy response to stress and healthy adrenal function. Stress-Adapt Day contains adaptogens to promote a healthy response to stress and healthy adrenal function. The Day version supports mood and energy production during stressful times.
