Kombucha contains substantial amounts of glucuronic
acid (GA). GA is well known as a deoxidant. In the body, it
combines with toxins like pharmaceuticals and environmental pollutants.
It then converts them into compounds that are soluble and the body can
excrete. Drinking kombucha may also help prevent tissues from
absorbing industrial toxins in the environment.
Kombucha contains abundant antioxidants including
vitamins E, C, beta-carotene, and other carotenoids. Like black tea,
kombucha also contains polyphenols and other compounds with antioxidant
powers. But because it is fermented, kombucha is much more powerful than
plain tea. Its antioxidant activity has been found to be 100 times higher
than vitamin C and 25 times higher than vitamin E. For that reason,
drinking traditional kombucha may help cure chronic illnesses caused by
Kombucha sets iron free from black tea. That helps increase levels of blood haemoglobin,
and improves oxygen flow to tissues. It also improves the body's
absorption of other non-heme (plant-derived) iron.
Oxidative stress suppresses the immune system but
kombucha's high levels of vitamin C supports immunity. Its
antioxidant power also protects against cell damage, inflammatory diseases,
suppressed immunity, and tumours.
5. Gastric Illnesses
Nonsteroidal anti-inflammatory drugs (NSAIDs) are
toxic to the gut. They can lead to gastric ulcers. Indomethacin, a popular NSAID, can disrupt blood
circulation to the stomach's mucous membrane. Kombucha has been shown to
effectively heal gastric ulceration. The researchers believe the
fermented tea protects the mucin content of the stomach. Its antioxidant
activity also protects the lining of the gut. Kombucha also reduces
gastric acid secretion that can damage the mucous membrane. In fact,
kombucha has been found as effective in healing ulcers as prescription omeprazole
(brand name Prilosec).
Kombucha helps balance the metabolism. Animal
studies show the tea may cause weight loss by encouraging calorie restriction.
Research dating back to 1929 found kombucha can
decrease blood sugar levels. More recent animal studies report that kombucha significantly reduces blood sugar levels in diabetic rats.
Another study suggested kombucha may be considered a candidate for the
treatment and prevention of diabetes.
8. Kidney Toxicity
Kombucha may help eliminate kidney damage caused by
environmental pollutants and may be beneficial to patients suffering from renal
impairment. Kombucha has also
been used to prevent calcification in the kidney and may prevent the formation
of kidney stones.
9. Endothelial Function
Oxidative stress can damage the lining of blood
vessels. That damage is a precursor to atherosclerosis, and a
threat to heart health. Antioxidants in kombucha help promote
regeneration of cellular walls in blood vessels.
In clinical trials involving 52 atherosclerotic
patients with high cholesterol,
kombucha helped lower levels to normal. In studies involving ducks, kombucha
significantly reduced levels of LDL cholesterol and simultaneously raised HDL
levels after just 10 days. Other animal studies show kombucha may
decrease total cholesterol as much as 45–52%. It may also significantly
decrease triglyceride and LDL levels while increasing HDL.
Kombucha has been used to prevent headaches and
dizziness caused by hypertension.
It's been recommended for treating high blood pressure.
Organic acids found in kombucha convert trivalent
iron compounds from plant sources to divalent iron ions. This makes iron
from plant sources more available to the body. And vitamin C in kombucha
enhances iron absorption. Researchers suggest kombucha is
particularly recommended for elderly people and vegetarians because it enhances
the absorption of iron and helps prevent iron deficiency.
13. Liver Function
Kombucha protects against liver toxicity in animals
from overdoses of acetaminophen (Tylenol). Researchers suggest it might provide a useful
therapy for humans as well.
14. Nervous System
Kombucha contains several amino acids, methyl
xanthine alkaloids (caffeine, theophylline, and theobromine), ascorbic acid
(vitamin C), and B vitamins (including folic acid-B9), necessary for normal
metabolism in the nervous system. It can help with headaches,
nervousness, and epilepsy prevention. It may also prevent depression in
Daily kombucha may help asthma patients. It
contains significant amounts of theophylline, a bronchodilator. The
treatment dose of theophylline is 0.18–1.0 g daily. Just one cup of
kombucha contains about 1.44 mg.
16. Joint Problems
Glucuronic acid in kombucha can be converted by the
body into glucosamine, chondroitin-sulphate, and other polysaccharides and glycoproteins
associated with cartilage, collagen, and the fluid that lubricates joints. It may also help relieve arthritis,
rheumatism, and gout.
