The Top 6 Immune-Boosting Superfoods Under 100 Calories
1. Blueberries (83 calories per cup)
Blueberries are tiny but mighty. A single cup contains just 83 calories but delivers a hefty dose of vitamin C and anthocyanins—antioxidants known to enhance immune cell function. Studies show regular blueberry consumption may reduce oxidative stress and inflammation.
“Blueberries rank among the highest antioxidant-rich foods, making them a top choice for immune support.” — Journal of Nutritional Biochemistry
2. Spinach (7 calories per cup, raw)
Popeye was onto something! Spinach is loaded with folate, iron, and vitamins A and C—all crucial for immune function. Its high beta-carotene content helps your body produce infection-fighting white blood cells.
| Nutrient | Amount per Cup (Raw) |
|---|---|
| Vitamin A | 56% DV |
| Vitamin C | 14% DV |
| Folate | 15% DV |
3. Greek Yogurt (100 calories per ¾ cup)
Probiotic-rich Greek yogurt supports gut health, where 70% of your immune system resides. Choose plain varieties to avoid added sugars, and look for live active cultures like L. acidophilus.
4. Almonds (98 calories per 14 nuts)
These crunchy nuts provide vitamin E, a fat-soluble antioxidant that protects cell membranes from damage. Just a small handful delivers nearly half your daily vitamin E needs.
5. Bell Peppers (37 calories per medium pepper)
Red bell peppers contain 3 times more vitamin C than oranges! Vitamin C stimulates white blood cell production and acts as a powerful antioxidant.
6. Green Tea (2 calories per cup)
Packed with epigallocatechin gallate (EGCG), green tea enhances immune function while providing minimal calories. Its L-theanine content may also help reduce stress—a known immune suppressor.
