Taro, burdock, and cassava are flexing lately like contestants at the Miss Universe pageant, commanding the spotlight on your plate. Spirulina, seaweed, and black garlic bring antioxidant-fueled superpowers to meals, transforming them into healthy goodness. These ancient foods are rewriting the rules, proving roots, algae, and tubers can serve nutrition and Instagram-worthy flair simultaneously.
From spirulina to konjac, food labels today reveal ingredients that might sound exotic or even mysterious, but have been around for centuries. They were just off-radar, like a sneaky sniper on a rooftop. There are the likes of ancient roots, tubers, and algae, which are being rediscovered for their functional benefits, from boosting gut health to providing antioxidants. Today, health-conscious consumers are embracing these once-obscure foods for their nutritional power, sustainability, and versatility. While these foods might be unconventional and not exactly as tasty as potatoes, carrots and more, they have a lot of potential.
An algae, spirulina, is available in powders and tablets, and is said to have strong antioxidant and anti-inflammatory properties from its phycocyanin compound. It’s a blue-green microalgae celebrated as a superfood due to its dense nutrition profile – up to 60-70% protein, plus vitamins, and iron. Clinical studies suggest it may improve lipid profiles (reducing LDL and triglycerides), and some trials show modest blood-pressure benefits. However, quality matters: spirulina can be contaminated with heavy metals if poorly sourced, so third-party tested products are safer.
Native to Peru’s high Andes, maca root is an adaptogenic tuber long used in traditional medicine. Some human and animal studies suggest it may boost energy, improve mood, and reduce fatigue. It's also linked to hormonal balance, with preliminary research hinting at benefits for libido and fertility, although evidence is still limited. Maca contains fibre, vitamins, and plant compounds, and is commonly available in powdered or capsule form. While generally considered safe, high doses may affect thyroid function (due to goitrogens), so usage should be moderated.
There is nothing extraordinary about this one; it’s just ordinary garlic, which is aged under high heat and humidity. The ageing transforms the garlic (allicin) into more stable antioxidant-rich compounds like S‑allylcysteine and gives it a sweet flavour, almost similar to balsamic vinegar. Compared to raw garlic, black garlic has higher antioxidants. It might help regulate blood sugar, reduce LDL cholesterol, support brain health and support cardiovascular health. It is used for marination, sauces and dips. Because of its controlled ageing process, it is considered a gourmet ingredient.
It might seem like cassava recently went viral, but it has been around for longer in India. It’s locally known as ‘kappa’ or ‘tapioca’. This starchy root is naturally gluten-free and high in carbohydrates. Cooked cassava contains resistant starch, which can support gut health by acting as a prebiotic. It’s also a good source of vitamin C, copper, and B vitamins. But raw cassava contains cyanogenic glycosides, making proper preparation (soaking and cooking) essential to avoid it being toxic. Most fermented cassava-based foods show promising antioxidant and gut-boosting properties, too.
Konjac, also known as elephant yam, is prized for its root’s soluble fibre called glucomannan. This fibre can absorb water and form a thick gel, which slows sugar absorption, enhances satiety, and helps manage blood lipids. Studies in animals show konjac glucomannan can reduce LDL cholesterol and improve insulin regulation. It also acts as a prebiotic, promoting beneficial gut bacteria and contributing to weight control. Elephant yam is already used in India in stir fries, chips and pakoras; the term ‘konjac’ is used widely now, and because of this, it has experienced a resurgence.
Just like konjac and cassava, taro is an ancient starchy tuber rich in fibre, resistant starch, potassium, magnesium, and vitamins like B6, C, and E. Its resistant starch and dietary fibre help regulate blood sugar and may aid weight management by boosting satiety. Taro also contains polyphenols (quercetin) with antioxidant and potential anti-cancer properties. Moreover, preliminary studies indicate anti-inflammatory effects through flavonoids and saponins. Note: Raw taro contains oxalates that can irritate, so cooking it is important.
Burdock root (Arctium lappa) is a traditional medicinal plant widely used for its anti‑inflammatory, antioxidant, and diuretic properties. It contains inulin and other prebiotic fibres, feeding beneficial gut bacteria. Studies suggest it may help lower blood pressure and cholesterol and support detoxification. It’s also used topically (or internally) for skin health, including acne, due to its antibacterial compounds. However, human research is still limited, and it could interact with certain medications.
Seaweed (marine algae) is a nutrient-rich, ancient ingredient packed with fibre, iodine, and antioxidants like vitamins A, C, and E. Its fibre helps promote digestive regularity, while compounds like fucoxanthin (in brown seaweed) may support weight management and metabolic health. Iodine from seaweed also aids thyroid function, but overconsumption can risk excessive iodine or heavy metal exposure, depending on the source.
From the centuries-old tubers to nutrient-dense marine algae, these ancient ingredients deserve their spot in the limelight. They’re front and centre on today’s menus and labels, and their resurgence reflects a growing trend of functionality, sustainability, and flavour.
