What are the side effects of tannins in tea?
When consumed in high amounts, tannic acid can irritate the lining of the stomach and intestines, leading to symptoms such as nausea, vomiting, and abdominal pain. This is particularly relevant for individuals who consume large quantities of tea or red wine, both of which contain significant amounts of tannins. Tannins have also been reported to exert other physiological effects, such as to accelerate blood clotting, reduce blood pressure, decrease the serum lipid level, produce liver necrosis, and modulate immunoresponses. The dosage and kind of tannins are critical to these effects.Tannins are considered nutritionally undesirable because they precipitate proteins, inhibit digestive enzymes and affect the utilization of vitamins and minerals. Tannin components have also been implicated in the high levels of cheek and oesophageal cancers in certain regions of the world.As tannins are a product of the skin of a grape, if intolerance is present and they are ingested the body will treat it as a foreign invader and trigger an immune response. This then causes signs of an allergen such as swollen lips, digestive and bowel issues.Known for their antioxidant, anti-inflammatory, and cardioprotective properties, tannins are associated with a reduced risk of chronic diseases such as cardiovascular disease, cancer, and diabetes.
Which teas are tannin free?
Rather, herbal teas draw on the full variety of herbs, flowers, roots, spices or fruits that the botanical kingdom has to offer, from classics like peppermint and camomile, to the more exotic cardamom and turmeric.

Herbal tea – normally no tannins or caffeine Varieties include ginger, ginkgo biloba, ginseng, hibiscus, jasmine, rosehip, peppermint, rooibos (red tea), chamomile, and echinacea.Black tea typically has the highest tannin concentration, followed by oolong and green teas.Black tea typically has the highest tannin concentration, followed by oolong and green teas.
Which tea is very high in tannins?
Black tea typically has the highest tannin concentration, followed by oolong and green teas. All brewed tea and tea leaves had detectable lead levels with Chinese oolong teas having the highest levels, followed by green tea and regular black tea having lower levels. Organic white teas had the lowest lead level.Tannin Levels in Different Types of Tea Some sources suggest that black tea has the highest tannin content among the types, whereas green tea is often considered to have the lowest levels.
What is the healthiest tea to drink?
Green tea wins as the most healthy tea,” says Ashley Simper, the manager of dietetic services with OSF HealthCare “Drinking green tea, at least three or more cups a day, leads to health benefits when it comes to cardiovascular disease, cancer and the overall risk of mortality. Massive black tea consumption has been linked to kidney failure due to its high oxalate content (acute oxalate nephropathy).Teas like turmeric, green, fennel and ginger, and slippery elm contain properties that may reduce inflammation and digestive distress. With your doctor’s approval, try adding these teas to your daily routine to see if they may benefit your symptoms.Another great drink is ginger tea. It reduces inflammation throughout your body, including your kidneys. This anti-inflammatory effect may help reduce your risk of chronic kidney disease. Ginger protects your liver and improves digestive health as well.But if you are prone to kidney stones, limit your tea consumption to 1-2 cups per day to avoid increasing your risk of kidney stones. Choose a Lower-Oxalate Tea: Green, white, and herbal teas have much lower oxalate levels than black tea. These can be a much better option for people at risk of developing kidney stones.
Are tannins healthy or unhealthy?
Tannins are considered nutritionally undesirable because they precipitate proteins, inhibit digestive enzymes and affect the utilization of vitamins and minerals. Tannin components have also been implicated in the high levels of cheek and oesophageal cancers in certain regions of the world. In this context, tannins can modulate gut microbial composition and function, selectively inhibiting pathogens and promoting the growth of beneficial bacteria (Ozdal et al. Tannins are known also for their capacity to interact with proteins and carbohydrates, among other compounds.
What neutralizes tannins in tea?
Some tea enthusiasts swear by adding a squeeze of lemon juice to neutralise tannins and bring out the flavour. Although moderate tea consumption is typically healthy for most people, drinking too much may lead to side effects, such as anxiety, low quality sleep, and headaches. Most side effects are related to tea’s caffeine and tannin contents.The liquid that remains trapped inside the tea bag has even higher instances of tannic acid than what is able to steep out of the bag on its own,” they add. By squeezing the tea bag, you inadvertently release these tannic acids into your tea and in turn create a far more bitter, sour, and acidic cup of tea.This can lead to acidity, reflux, bloating, and gut irritation. Over time, this habit of having tea on an empty stomach can cause chronic inflammation, poor digestion, or even gut lining damage (what we call leaky gut). Tannins in tea can interfere with nutrient absorption, especially iron and calcium.
