Superfoods supposedly have beneficial health benefits, including antioxidants, anti-inflammatory properties, and antifungal properties. However, some superfoods are expensive, so this article explores whether they’re worth the hype.

Dark, leafy, green vegetables like spinach, kale, collard greens, and Swiss chard are high in fiber and contain vitamin C, zinc, folate, calcium, and magnesium.

Nutritionists suggest these greens can help reduce the risk of type 2 diabetes and heart disease because they contain high levels of carotenoids (anti-inflammatory compounds).

2. Berries

The EGCG gives this superfood its reputation for protecting against chronic diseases, improving cognitive function, and helping maintain healthy blood sugar levels.

Matcha green tea is a similar tea that comes in powder form.

Whole eggs are high in protein and nutrient-rich in B vitamins, selenium, vitamin A, iron, choline, and phosphorus. Eggs contain two unique antioxidants: lutein and zeaxanthin.

The National Library of Medicine suggests that eating eggs can improve HDL (good) cholesterol and heart health.

Popular nuts and seeds include sunflower, almonds, pumpkin seeds, chia seeds, flaxseeds, brazil nuts, cashews, pistachios, hemp and macadamia nuts.

Although a superfood, nuts, and seeds are calorie-rich, so limit consumption to a small handful daily.

Kefir is a fermented drink typically made from cow’s milk. It contains protein, B vitamins, calcium, probiotics, and potassium. Because of the fermentation process, it is generally suitable for those with lactose intolerance.

Olive oil is a superfood that contains high concentrations of monounsaturated fatty acids (MUFAs) and polyphenolic compounds.

Olive oil can reduce the risk of diabetes and heart disease, as opposed to saturated fats like butter.

Turmeric is a bright yellow/orange spice used for cooking. The active compound, curcumin, is a potent antioxidant and anti-inflammatory. The body does not easily absorb curcumin, but adding another spice, like black pepper, helps absorption.
