Emotional stress, smoking (including secondhand smoke), environmental pollution, insufficient sleep, and lack of exercise are all immunity killers. They increase free radical production, accelerate nutrient depletion, weaken immune cell function, and inhibit nutrient absorption.
Therefore, balance is key—both in your diet and your mindset! Cultivating exercise habits and leisure interests while breaking unhealthy routines is crucial. Embracing a tolerant, easygoing, humorous, and cheerful disposition is an even more effective way to boost immunity.
Excessive Fat
Certain fats increase free radical production (e.g., excessive unsaturated fatty acids), others accelerate nutrient depletion (e.g., refined sugars, alcohol, caffeine, medications), some weaken immune cell function, and others inhibit nutrient absorption (e.g., alcohol and certain drugs). Fried foods, snacks, and carbonated beverages should be blacklisted.
Balanced Diet, No Food Restrictions
While it may sound obvious, obtaining ample nutrition from natural, fresh foods is the dietary secret to maintaining immune function. Prioritize whole grains, ample vegetables and fruits, soy products, and moderate amounts of dairy, eggs, fish, and meat to ensure comprehensive nutritional intake.
