Below are 5 groups of people who should drink guava leaf water regularly based on reputable scientific evidence.
People with diabetes
Guava leaves have been shown to control blood sugar levels. According to research by the National Institute of Food and Nutrition in Japan, drinking guava leaf water helps reduce glucose absorption after meals and stabilizes blood sugar.
Compounds like quercetin and flavonoids in guava leaves help inhibit the enzyme alpha-glucosidase, slowing down the digestion of carbohydrates.
This is very helpful for people with diabetes or prediabetes.
People with poor digestion or intestinal disease
Guava leaf juice has long been used to treat digestive problems such as diarrhea, bloating, and stomachache.
The World Health Organization (WHO) acknowledges that the tannin compounds in guava leaves have antibacterial and anti-inflammatory properties, which help inhibit intestinal pathogenic bacteria such as E. coli or Salmonella.
At the same time, guava leaves also stimulate the production of digestive enzymes, helping to improve overall digestive function.
Overweight, obese people
People who want to lose weight or maintain their weight should add guava leaf water to their diet. According to a study published in the journal Nutrition & Metabolism, guava leaf water helps reduce fat accumulation by inhibiting the conversion of starch into sugar in the body.
The antioxidants in guava leaves also help burn calories and improve metabolism.
People with cardiovascular disease
Guava leaf water improves heart health thanks to its ability to reduce bad cholesterol (LDL) and increase good cholesterol (HDL).
According to the American Heart Association (AHA), polyphenols and flavonoids in guava leaves help prevent atherosclerosis, reduce blood pressure, and protect the heart.
For people at high risk of cardiovascular disease, drinking guava leaf water regularly is a natural and effective solution.
People with weakened immune systems
Guava leaves are rich in vitamin C and powerful antioxidants, which help boost the immune system. A study by the National University of Singapore found that guava leaf extract has the ability to activate immune cells, helping the body fight pathogens from bacteria, viruses and free radicals.
Especially during cold or epidemic season, guava leaf water is a good choice to protect health.
