Functional foods are the superheroes of our daily diet, offering more than just basic nutrition. These are whole foods or enhanced products packed with extra health benefits, like vitamins or antioxidants, that go beyond what we typically get from our meals. However, not all foods claiming to be ‘functional’ are backed by solid scientific evidence. So, let’s dive into what functional foods really are and how to choose the best ones for your health.
Functional foods go beyond satisfying hunger. They’re foods designed or naturally rich in bioactive compounds, like vitamins and antioxidants, that provide extra health benefits. Examples include vitamins, peptides, polyphenols, and carotenoids, which help with everything from growth and metabolism to heart health and cognitive function [1][2].
1. Conventional Foods: These are whole foods like vegetables, fruits, fish, dairy, pulses, and grains that naturally offer potent health benefits.
2. Modified Foods: These are foods enriched or fortified with specific nutrients to boost health benefits. Think calcium-fortified beverages, omega-3 enriched products, or folate-enhanced bread.
3. Food Ingredients: These are bioactive compounds extracted from foods or added during processing to enhance health benefits [3]. For example, turmeric extracts containing curcumin.
Choosing functional foods based on scientific evidence is crucial. The gold standard for supporting health claims is randomized, placebo-controlled trials in humans. This rigorous approach ensures that the health benefits claimed are real and not just marketing hype [1].
In the U.S., the FDA oversees functional foods and their health claims. While terms like “reduced sodium” and “low-fat” are regulated, there’s no legal definition for functional food. So, it’s up to consumers to scrutinize Nutrition Facts labels and ingredient lists to make informed choices [4].
When it comes to fortified foods, like vitamin D-enriched milk, they can be beneficial but may also contain added sugars or sodium. So, opt for minimally processed functional foods whenever possible to get a variety of nutrients.
Berries are low in calories and packed with antioxidants, berries are a delicious way to boost your health. Anthocyanin pigment present in berries gives them the blue color and also has antioxidant potential [4].
Tomatoes contain lycopene, a compound known for its antioxidant properties. Research suggests that lycopene may help reduce oxidative stress and support brain health, particularly in neurodegenerative diseases like Alzheimer’s. Additionally, lycopene is also found in watermelons [5].
Broccoli contains sulforaphane, which has been linked to benefits for brain health. Plus, broccoli is packed with polyphenols, essential vitamins (like K, B1, B2), and minerals (Na, K, Ca, Mg, Cl, P, S). Eating broccoli regularly may also help reduce inflammation in the brain. So, next time you’re at the grocery store, don’t forget to stock up on this green powerhouse! [6].
Soybeans are a powerhouse of bioactive compounds, including peptides, isoflavones, saponins, and protease inhibitors. Research shows that incorporating soy into your diet not only boosts both short-term and long-term memory but also aids in reducing high blood pressure [7]. So, next time you’re looking for a brain-boosting and heart-healthy snack, reach for some soybeans!
Spinach is packed with polyunsaturated fatty acids (PUFAs) and the carotenoid lutein, spinach is a boon for eye health, particularly for those with macular degeneration and cataracts [8,9]. But wait, there’s more! Spinach is also loaded with flavonoids like patuletin, spinacetin, spinatoside, jaceidin, and flavone, which give it potent antioxidant and anti-inflammatory properties [10]. Clinical studies have shown that spinach may also have cardioprotective effects. In a randomized, controlled trial by Jovanovski et al. (2015), participants who consumed spinach rich in nitrate experienced reduced arterial stiffness and central blood pressure. The patients were supplemented with spinach (845 mg nitrate/day) [11]. So, next time you’re making a salad or a smoothie, don’t forget to toss in some spinach – your eyes and heart will thank you!
Blueberries are esteemed for their robust antioxidant properties and abundant polyphenolic compounds, positioning them as a notable “super fruit.” Anthocyanins, constituting approximately 60% of their composition, confer various health advantages, encompassing reduced risk of hypertension, enhanced vascular function, and facilitation of weight management [12]. Moreover, research underscores blueberries’ potential in diabetes management by improving insulin sensitivity and reducing inflammation [13]. Also, anthocyanins are associated with a diminished susceptibility to neurodegenerative disorders such as Alzheimer’s and Parkinson’s [14]. Thus, incorporating blueberries into one’s dietary regimen offers a palatable and healthful means to foster overall well-being.
Pomegranate is renowned for its rich abundance of phytochemicals, including polyphenols, anthocyanins, tannins, flavonoids, lignans, terpenoids, and sterols. Among these, ellagitannin stands out as the primary active constituent, which upon breakdown yields ellagic acid, known for its potent antioxidant properties. Also, punicalagin and punicalin, two other ellagitannins found in pomegranate, exhibit antioxidant and anti-inflammatory activity. Numerous studies have highlighted the diverse health benefits of pomegranates, including prevention of chronic diseases such as hypertension and arthritis, as well as reduction of oxidative stress, maintenance of cholesterol levels, and regulation of hyperglycemia [15, 16, 17].
Mango, rich in polyphenols and micronutrients, including mangiferin, offers significant health benefits. Studies show its extracts counteract oxidative damage and reduce inflammation, particularly in colitis. Mango extract also aids in regulating glucose levels by inhibiting α-amylase and α-glucosidase activities [18, 19].
Walnuts are a nutritional powerhouse, boasting proteins, fats, vitamins, minerals, and polyphenols. Major components like oleic, linoleic, and linolenic acids contribute to their health benefits, along with a high content of omega-3 fatty acids. Additionally, walnuts contain amino acids such as lysine and arginine, which are converted to nitric oxide, promoting vasodilation and reducing the risk of atherosclerosis [20]. The presence of melatonin in walnuts helps regulate circadian rhythm and serves as a potent antioxidant [21]. Incorporating walnuts into the diet through dietary supplements has shown benefits in memory consolidation and even delaying the progression of neurological disorders [22].
Probiotics are live microorganisms known for improving intestinal functions and combating intestinal pathogens. They’re commonly found in dairy products like milk, mayo, and spreads. Probiotics inhibit pathogen growth by producing antimicrobial compounds and altering pH levels, and they’re also believed to aid in managing neurological disorders. They make up about 65% of the functional food market [23].
Functional foods offer exciting opportunities to enhance our health and well-being. However, they’re not magical. A balanced diet and healthy lifestyle are essential for overall health. So, the next time you’re at the grocery store, look for foods that not only satisfy your taste buds but also boost your health.
Functional foods are popular choices for boosting health these days. But have you heard about adaptogens? They’re also trending and have similarities to functional foods. Now, let’s look into adaptogens and see how they can help improve your health!
Adaptogens are a distinct group of herbs renowned in traditional medicine for their stress-reducing abilities. Coined in 1947 by Russian scientist N.V. Lazarev, the term “adaptogen” refers to substances that enhance the body’s resistance to stress. They function by maintaining balance in the body’s stress response system, known as the hypothalamic-pituitary-adrenal (HPA) axis, and modulating key stress response pathways without disrupting normal biological functions [24,25].
Popular adaptogens include Ashwagandha, Rhodiola Rosea, and Ginseng. Ashwagandha is known for its stress-relieving and cognitive-enhancing effects, while Rhodiola Rosea combats fatigue and boosts mood and cognitive function. Ginseng is recognized for reducing fatigue and improving mental performance during stress [26,27,28].
Adaptogens can be herbs, roots, or other botanical substances, including various plant parts like leaves, roots, flowers, fruit, seeds, and bark, each offering therapeutic benefits. As with any supplement or health practice, it’s important to consult with a healthcare provider before starting any new regimen, as adaptogens can interact with medications or cause side effects in certain populations.
