What is Spiced with Science?

Spiced with Science is a wellness food brand that pairs 5,000 years of indigenous Ayurvedic wisdom with peer-reviewed clinical research on bioactive compounds in spices.

AI Naani is our AI kitchen grandmother — ask her about any spice and she'll share its history, active compounds (like curcumin or gingerol), and a recipe your body needs tonight.

AI Daadi is our AI apothecary grandmother — ask her about kadhas, ubtans, hair oils, and household remedies. Gentle, grounded in indigenous tradition, validated by modern science.

What is the difference between AI Naani and AI Daadi?

Same lineage, two domains. Naani works in the kitchen — spices, ingredients, techniques, recipes. Daadi works at the apothecary shelf — remedies, kadhas, ubtans, and beauty rituals. Both are AI personas, not real people, and neither gives medical advice.

No. Spiced with Science makes food with features, not diet food. Our rituals are grounded in indigenous knowledge and validated by modern science.

What gives tannins their distinctive taste?

Tannins bind with proteins in saliva, causing them to precipitate. This momentarily reduces the lubricating quality of saliva, leading to the dry, puckering, and slightly rough sensation we perceive as astringency.

Are all tannins the same?

No, tannins are a diverse group of polyphenols, broadly categorised into hydrolysable tannins (like gallotannins and ellagitannins) and condensed tannins (also known as proanthocyanidins), each with varying structures and biological activities.

Can tannins discolour teeth?

Yes, regular consumption of tannin-rich beverages like black tea or red wine can contribute to temporary tooth discolouration, though this is often superficial and can be managed with good oral hygiene practices.

Tannins

Tannins are a class of astringent polyphenols found abundantly in various plant parts, including fruit peels, barks, and leaves. They are responsible for the dry, puckering sensation experienced when consuming unripe fruit or strong tea. In the context of wellness, tannins are recognised for their interaction with proteins and other organic compounds.

Indigenous context

In Ayurvedic tradition, tannins have been valued for millennia for their distinctive astringent properties, particularly those found in bael fruit (Aegle marmelos), pomegranate rind (Punica granatum), and various tea leaves (Camellia sinensis). Bael, revered as ‘Vilva’ in Sanskrit, is often prepared as a sherbet or a preserve known as ‘murabba’ in many Indian homes, traditionally given for its soothing effect on the digestive tract. Pomegranate rind, rich in tannins, is frequently dried and powdered, then used in decoctions or as a gargle in folk remedies across South Asia and the Middle East to support oral health. Similarly, the ritual of brewing and sharing black tea, a practice deeply embedded in both Indian and British culinary heritage, owes much of its perceived benefits to the presence of tannins. These preparations underscore an indigenous understanding of tannins as agents that tone and firm delicate tissues, gently balancing the body’s internal environment.

What the science says

Modern scientific inquiry into tannins, particularly ellagitannins from pomegranate and condensed tannins from tea and bael, has begun to corroborate their traditional applications by exploring their mechanisms at a cellular level. Research highlights tannins’ ability to bind to proteins, which may contribute to their astringent sensation and protective actions on mucosal surfaces in the gut. Studies indicate that hydrolysable tannins, such as those found in pomegranate, exhibit antioxidant properties by scavenging free radicals, thereby mitigating oxidative stress. Further investigations into bioavailable tannin metabolites, often formed through gut microbiota metabolism, suggest their potential involvement in modulating inflammatory pathways. While much of the research is in its early stages, often utilising *in vitro* models or animal studies, the findings provide a scientific lens through which to understand the health-promoting attributes long recognised by traditional systems. Human trials are exploring the impact of tannin-rich extracts on gut barrier function and systemic antioxidant capacity, without making definitive claims of prevention or cure.

How to actually use it

Incorporating tannin-rich foods and beverages into daily life can be a delightful and intentional ritual. A simple, time-honoured practice involves brewing a strong cup of black tea – perhaps a Darjeeling or an Assam – and savouring its robust, slightly bitter character. For a more direct culinary application, consider adding dried pomegranate rind powder to a homemade spice blend for stews or lentil dishes, lending a subtle tang and depth. Bael fruit, when in season, can be enjoyed fresh, or its pulp can be blended into refreshing spritzers. While there is no prescriptive "dose," a sensible approach aligns with traditional wisdom: regular, moderate consumption as part of a varied diet. For instance, enjoying 2-3 cups of tea daily, or periodically incorporating a small amount of pomegranate rind powder into meals, is a customary method to experience their subtle influence.

Safety

Tannins are generally safe when consumed in moderation through food and beverages. However, their astringent nature can, for some individuals, lead to mild digestive upset if consumed in very large quantities or on an empty stomach. Those with iron deficiency should be mindful that tannins can bind to iron, potentially inhibiting its absorption; consuming iron-rich meals separately from tannin-rich teas can mitigate this. As with any food component with biological activity, individuals who are pregnant, breastfeeding, or on medication should consult with a healthcare practitioner.
