You may have heard about superfoods, but what exactly are they? The truth is, there are no scientific markers that define what a superfood is. However, the term is loosely used to describe nutrient-dense foods with important health benefits.1 They are typically packed with vitamins, minerals, antioxidants and other beneficial compounds.

Examples of superfoods include berries (like blueberries and açai berries), leafy greens (such as kale and spinach), fatty fish (like salmon and sardines), nuts and seeds (such as almonds and chia seeds) and certain grains (like quinoa).

Incorporating superfoods into your diet can help you target specific health goals, like weight loss, improved digestion, enhanced immunity and increased energy. You can choose from a wide range of foods to add to your daily meal planning or try convenient superfood supplements.

Are adaptogens superfoods?

Yes. Adaptogens are a class of natural substances, including certain herbs and mushrooms, that may help the body adapt to stress and maintain balanced state.12 They have been used in traditional medicine systems, such as Ayurveda and Traditional Chinese Medicine, for centuries. Adaptogens are known for their ability to help the body respond to stressors, whether they are physical, emotional or environmental. They work by regulating the body’s stress response system, which includes the hypothalamus-pituitary-adrenal (HPA) axis.13 Examples of adaptogens include ashwagandha, rhodiola rosea, ginseng, holy basil (tulsi) and cordyceps mushrooms.

Are antioxidants superfoods?

Yes. Antioxidants are essential molecules that play a critical role in safeguarding the body against oxidative stress.14 Oxidative stress occurs when there is an imbalance between free radicals, highly reactive molecules with unpaired electrons and antioxidants in the body. These free radicals can cause cellular damage, impacting proteins, DNA and other vital components, leading to various health issues and contributing to the aging process. Antioxidants act as defenders by neutralizing free radicals. They do this by donating electrons to stabilize the radicals, preventing them from causing harm to cells and mitigating potential damage. Examples of antioxidant-rich foods include berries, citrus fruits, leafy greens and dark chocolate.

Are phytonutrients superfoods?

Yes. Phytonutrients or phytochemicals are naturally occurring compounds found in plants that contribute to their vibrant colors, flavors and protective mechanisms. They exhibit antioxidant properties,15 meaning they can neutralize harmful free radicals in the body, reducing oxidative stress and inflammation. Plus, they with a range of health advantages, including supporting cardiovascular health, supporting the immune system, reducing the risk of chronic diseases and enhancing overall well-being.16

Which superfoods can support gut health?

Superfoods can contribute to better gut health by supporting a healthy balance of gut bacteria and promoting better digestion. Ginger has anti-inflammatory properties that may alleviate digestive discomfort and promote gut health.17 Another gut-friendly superfood is curcumin, the active compound in turmeric. It may support certain health-related concerns and has antioxidant properties.18 19 Other superfoods that may help with digestion include miso, kimchi, kefir, tempeh and bananas.

Which superfoods are best for supporting the immune system?

Many superfoods may help support your immune system by providing essential nutrients and immune-boosting compounds. Citrus fruits, such as oranges, grapefruits, lemons and limes, are rich in vitamin C, a key nutrient that stimulates the production of white blood cells, crucial for immune function.20 Garlic contains allicin, a compound renowned for its antimicrobial properties, potentially aiding the immune system in combatting infections.21 Other superfoods you may want to try include almonds, bone broth, kombucha and salmon.

Why should I take superfood supplements?

Although you can get many superfoods from diet alone, taking supplements can help you consistently get your daily dose (especially for those days when you’re short on time). One significant benefit of taking superfood supplements is the convenience they offer. Supplements provide an easily accessible and time-efficient solution, helping you to access essential nutrients without the need for extensive meal planning or preparation. Also, supplements assure you year-round availability. Certain superfoods are seasonal, which means they may not be readily accessible at all times. Supplements bridge this gap, ensuring that you can reap the benefits of these superfoods consistently, regardless of the season.

How do I choose which superfoods to eat?

Start by considering your individual health goals, dietary preferences and nutritional needs. Whether you’re aiming to boost your immune system, improve digestion, enhance cognitive function or manage your weight, understanding your goals will guide your superfood selection. Take stock of what you typically eat to identify any nutritional gaps. If you’re lacking in certain vitamins, minerals or antioxidants, look for superfoods that can fill those gaps. For example, if you rarely consume fish, you might consider omega-3-rich superfoods like chia seeds or flaxseeds or taking fish-oil supplements. If you’re unsure which superfoods are best for you, consult a healthcare provider. They can assess your specific needs and recommend a personalized superfood plan.
