The efficacy of drinking hibiscus tea
In the trend of pursuing health and wellness, hibiscus tea has attracted attention due to its vibrant color and unique benefits. The red calyces from the malvaceae plants release abundant active substances when soaked in hot water. However, controversy over whether it can aid in losing weight has always existed. Today, we will unveil its true effects through a scientific perspective.
Analysis of the core benefits of hibiscus tea
1. Heat-clearing and fire-reducing mechanism
According to the "Chinese Pharmacopoeia," hibiscus has a sour and cool taste, and the contained malic acid can regulate the body temperature center. Drinking hibiscus tea at 40-50℃ in summer can increase the expansion rate of capillaries by 20%, accelerating the evaporation of sweat to carry away body heat.
2. Antioxidant beauty benefits
Every 100 grams of hibiscus contains 34mg of vitamin C, combined with flavonoid compounds to form a double antioxidant barrier. Experiments show that continuous consumption for 30 days can reduce the content of malondialdehyde (an oxidation marker) in the skin by 17%, effectively delaying the loss of collagen.
3. Cardiovascular regulatory effects
The unique anthocyanin-3-glucoside in hibiscus can inhibit the activity of angiotensin-converting enzyme. Clinical trials show that drinking 300ml of hibiscus tea daily for 4 weeks can result in an average decrease of 7.5mmHg in systolic blood pressure and a 3.5mmHg reduction in diastolic blood pressure.
4. Metabolism promotion characteristics
The combination of citric acid and malic acid forms a natural enzyme promoter, which can increase the activity of lipase by 2-3 times. The (T-W) Nutrition Society found that those who drink hibiscus tea after meals experience an increase in diet-induced thermogenesis by about 12%.
Verification of the weight-loss effects of hibiscus tea
Its weight-loss mechanism is mainly reflected in three aspects: anthocyanins inhibit pancreatic lipase activity, reducing fat absorption by 30%; dietary fiber increases satiety; and organic acids accelerate the decomposition of (G-Y) triglycerides. However, it is important to note that the daily intake should be controlled at 5-8 flowers, as excessive consumption may stimulate the胃 mucosa.
It needs to be clear that relying solely on hibiscus tea for weight loss is limited. It is recommended to combine it with 30 minutes of aerobic exercise daily, and under the premise of controlling total calorie intake, the monthly weight loss efficiency can be increased by 40%. Special groups such as pregnant women and those with low blood pressure should consult a physician.
