Top 7 Foods to Support Your Immune Health
A strong immune system is essential for overall wellness, helping your body stay resilient against everyday challenges. While a balanced lifestyle—including regular exercise, adequate sleep, and stress management—plays a key role, the foods you eat are a critical factor in supporting immune function. Nutrient-dense foods rich in vitamins, minerals, and antioxidants can provide the building blocks your body needs to maintain a healthy immune response.
In this article, we’ll explore seven foods that can help support your immune system, based on their nutrient profiles and well-established roles in promoting wellness. These foods are packed with essentials like vitamins C, E, and A, zinc, and other compounds that contribute to immune health. Let’s dive in!

1. Citrus Fruits
Citrus fruits are celebrated for their high vitamin C content, a key nutrient that supports immune health. Vitamin C acts as an antioxidant, helping to protect cells from oxidative stress, and supports the production of white blood cells, which are vital for immune function.*
Best Sources: Oranges, grapefruits, lemons, limes, tangerines, and clementines.
A medium orange provides about 70 mg of vitamin C, nearly meeting the daily recommended intake for adults. Add citrus to your diet by snacking on an orange, squeezing lemon juice over salads, or enjoying fresh grapefruit juice in the morning. Beyond immune support, vitamin C promotes healthy skin and wound healing.
Substantiation Note: Ensure claims about vitamin C’s role in immune function are backed by RCTs or authoritative sources like NIH dietary guidelines. Avoid implying disease prevention (e.g., “fends off illness”) without evidence.
2. Garlic
Garlic has long been valued in traditional practices for its potential to support health. It contains sulfur compounds, like allicin, which may help support the body’s natural immune response.* Garlic also offers anti-inflammatory properties that contribute to overall wellness.*
How to Use: ForCertaination Note*: Claims about garlic’s immune benefits (e.g., reducing cold duration) must be supported by RCTs. Avoid suggesting garlic “fights infections” unless substantiated with specific studies relevant to your audience.
3. Ginger
Ginger is a versatile root known for its anti-inflammatory and antioxidant properties, which may support immune health by reducing oxidative stress.* Its active compound, gingerol, supports overall wellness and may help soothe occasional discomfort, such as sore throats.*
How to Use: Add fresh ginger to teas, smoothies, or stir-fries. A soothing tea with ginger, lemon, and honey is a great way to enjoy its benefits.
Substantiation Note: Claims about ginger’s immune or anti-inflammatory effects require RCTs. Avoid implying it treats specific conditions (e.g., colds) unless supported by evidence.
4. Leafy Greens
Leafy greens like spinach, kale, and Swiss chard are nutrient powerhouses, rich in vitamins A, C, and E, which support immune function.* Vitamin A helps maintain healthy skin and mucous membranes, the body’s first line of defense, while vitamins C and E act as antioxidants.*
Best Picks:
-
Spinach: High in vitamins C, A, and folate for immune and digestive health.
-
Kale: Packed with vitamins A, C, and K to support overall wellness.
-
Swiss Chard: Offers vitamins A and C for immune support.
How to Use: Blend greens into smoothies, toss them in salads, or sauté them as a side dish.
Substantiation Note: Claims about vitamins supporting immune function are generally accepted but must align with dietary reference intakes or RCTs. Avoid implying disease prevention.
5. Yogurt
Yogurt is a rich source of probiotics, beneficial bacteria that support gut health, which is closely linked to immune function.* A balanced gut microbiome helps regulate immune responses and promotes overall wellness.*
How to Use: Choose plain, unsweetened yogurt with live and active cultures. Enjoy it with fruit, nuts, or as a base for smoothies. Fermented foods like kefir or sauerkraut also offer similar benefits.
Disclaimer: Zuma Nutrition’s Multi-Strain Probiotic Complex, which we received for review, may support gut and immune health.* Results may vary. These statements have not been evaluated by the FDA.
Substantiation Note: Probiotic claims must be backed by RCTs specific to the strains and dosages in your product. Disclose any material connections (e.g., free products) clearly.
6. Almonds
Almonds are a nutrient-dense snack packed with vitamin E, a fat-soluble antioxidant that supports immune function by protecting cells from oxidative stress.* A small handful (about 23 almonds) provides nearly half your daily vitamin E needs.
How to Use: Snack on almonds, sprinkle them on salads, or spread almond butter on fruit or toast. Walnuts and hazelnuts also offer similar benefits.
Substantiation Note: Vitamin E’s role in immune health is well-documented, but avoid exaggerated claims without specific studies.
7. Turmeric
Turmeric, known as the “golden spice,” contains curcumin, an antioxidant with anti-inflammatory properties that may support immune health.* When paired with black pepper, curcumin’s bioavailability increases, enhancing its effects.*
How to Use: Add turmeric to curries, smoothies, or golden milk. Zuma Nutrition’s Liposomal Curcumin Tonic, which we received for review, offers a bioavailable form of curcumin to support wellness.* Results may vary.
Substantiation Note: Curcumin’s immune benefits require RCTs specific to your product’s dosage and formulation. Clearly disclose any material connections.
