You have probably heard that 30 herbal tea is very effective for weight loss, even being called by some people "natural sibutramine".
But if you have not tasted it yet, you may be wondering: Why is this fame? Is he really effective?
Below, Fernanda Granja, clinical nutritionist specializing in functional nutrition, pediatrics and exercise physiology, answers this and other questions about 30 herbal tea.
Herbs in teas
Fernanda Granja explains that the 30 herbal teas, and even the 7 herbal teas, do not have a standard of the herbs used. "There is no formula or even pre-established herbs that can change according to the brand," he says.
However, according to the nutritionist, the most used herbs in these teas are: cascara sagrada, carqueja, horsetail, centella asiatica, senna, green tea and buggy herb.
Below, Fernanda Granja talks about the specific properties of these seven herbs:
Sacred Cascara: It is a potent laxative and normalizes bowel functions.
Carqueja: acts on liver and intestines; is hypoglycemic and diuretic; fights digestive problems and anemia.
Horsetail: is anti-inflammatory; aids in genital problems and excessive menses; clears lung and blood secretions; acts by replacing silicon lost in weight loss.
Asian Centella: it is invigorating; rejuvenates the brain by possessing alkaloid; normalizes collagen production; It is used for weight loss and skin treatments.
Senna: It is laxative and purgative.
Green tea: accelerates metabolism and has antioxidant action.
Bugre's Herb: is a diuretic; lowers cholesterol; decreases swelling of the legs; stimulates circulation and the heart; It is useful in skin conditions.
In the case of 30 herbal tea, other herbs that may be present in the composition are, for example:
- Avocado
- Artichoke
- Rosemary
- star anise
- Banchá
- Purge Potato
- Chilean Bilberry
- Chamomile
- Swamp cane
- Lemongrass
- Black tea
- Fennel
- Holy thorn
- Fucus vesiculosus
- Ginkgo biloba
- Soursop
- Guaçatonga
- Mallow
- Passion fruit
- Melissa
- Lieutenant Stick
- Stone breaker
- Cat nail
And in this sense, 30 herbal teas generally promise benefits such as speeding up metabolism, reducing appetite, assisting in localized fat reduction, being digestive, diuretic and laxative and much more.
But, as nutritionist Fernanda has already pointed out, these are just some examples of herbs, as the composition may change according to the brand of tea.
The 30 herbal teas can be found in stores that sell natural products, some pharmacies and can be found in capsule form.
The harm of this kind of tea
Seeing the possibility of a tea offering all these benefits, a lot of people surrender to them. Often taking too much of the drink a day. But is 30 herbal tea really beneficial?
Fernanda Granja points out that the use of teas containing more than three herbs are not indicated. This is because herbs interact with each other and can potentiate or inhibit the action of their compounds. Research says that mixing more than three herbs in one infusion is unnecessary since, from this, the active ingredient of plants can interact negatively with each other ?, explains.
In addition, according to the nutritionist, the indiscriminate use of herbal medicines can bring several harms to the body, such as:
- low absorption of vitamins and minerals due to diuretic effect;
- drop in blood pressure;
- may impair thyroid function;
- provide excess cramps and bowel movements;
- cause insomnia;
- trigger chronic diseases by their continued use.
Contraindications
Fernanda Granja emphasizes that the use of no tea should be continuous.
? Teas should still be avoided by hypertensive, pregnant women, nursing mothers and patients with chronic diseases. Ideally, the person consult with a doctor before consuming them ?, emphasizes the nutritionist.
Really beneficial teas
Fernanda Granja points out that the teas that are well defined in studies, which have the power to aid in weight loss, are green tea and white tea. "Both are potent antioxidants, speed up metabolism and are sources of vitamins C, K, B1 and B2," he says.
Consumption of green tea or white tea, according to the nutritionist, may help reduce the inflammatory process, prevent the development of chronic diseases, and stimulate weight loss due to the thermogenic effect.
Green tea inhibits the activity of intestinal lipase, the effect of which results in less absorption of triglycerides and cholesterol and may lead to less weight gain. However, due to the presence of tannins, substances that can inhibit nutrient absorption, it is recommended that this tea be consumed away from the main meals, so as not to affect this nutrient absorption, especially iron. Ideally, it should be taken an hour and a half after meals. Also, due to the presence of caffeine, it is important that these teas are avoided at night or from 4 pm ?, explains the nutritionist.
Still according to Fernanda, the ideal consumption of camellia sinenses (plant from which green and white teas are made) to guarantee the benefits of catechins is 4 to 5 cups a day, or 1 liter a day. • It is recommended to take camellia sinenses tea throughout the day, being 1 cup of 200ml every 2 hours. The benefit of ingesting green tea, as well as several other functional foods in fractional amounts, is that this way we ensure a greater absorption efficiency of the active ingredients that guarantee the benefits of its consumption ?, highlights.
The teas can be prepared in an amount sufficient to drink throughout the day, explains Fernanda Granja. However, it is important to remember that it should never be reheated. If the preference is for its hot consumption, it is interesting that it is consumed, soon after its preparation. It is not indicated even if it is sweetened, because it can change the properties of tea ?, concludes the nutritionist.
With all the tips, the question remains: despite all the benefits promised, but also taking into account the harms that this type of tea can offer, is it really worth sticking to 30 herbal teas?
If you decide to try this type of tea, remember that it can have side effects, so talk to your doctor and / or nutritionist before then.
