Science Says Guava Leaf Tea Helps With Weight Loss, Managing Diabetes; Here’s a Recipe

Guavas

For me, eating ripe, sliced guavas sprinkled with a pinch of salt and chilli powder brings with it an immense sense of nostalgia. There was a time when this was my daily snack at home, and we’d pluck the fruits off the lone guava tree in our backyard till there were none left. 

My grandmother encouraged us to eat the fruit with the seeds and rind, which she said were as nutritious as the flesh of the fruit. She’d do so with a stern warning to rinse the fruit well before consuming it. 

Guava, a tropical fruit that has its origins in Central America, was believed to have been brought to India by the Portuguese in the early 17th century. These fruits, which come in numerous varieties, are loaded with nutrients.

They are a rich source of Vitamin C, Vitamin A, potassium, manganese, and antioxidants. They are low in calories and rich in protein and fibre. Minerals like zinc, calcium, and iron are also present in smaller quantities, thereby making this the perfect healthy addition to one’s daily diet.

Several studies claim that guavas are good for boosting immunity, help manage diabetes, promote good heart health, aid weight loss, and have anti-aging properties.

And it’s not just the flesh of the fruit that has benefits to offer. Research shows that seeds, rind, and leaves all carry several merits. 

The extract of guava leaves has been a part of traditional medicine in different parts of the world. For example, Japan brews guava leaves to make herbal tea with medicinal properties.

“These leaves are a powerhouse of antioxidants like Vitamin C, and flavonoids such as quercetin,” Delhi-based nutritionist Anshul Jaibharat T told NDTV.

Here’s why you should, too, brew tea from guava leaves: 

1. Manages blood sugar levels

Scientific studies have found that guava leaf extract has properties that improve blood sugar levels and help long-term blood sugar control, as well as manage insulin resistance.

It was also found that drinking guava leaf tea after meals reduced blood sugar spikes by moderating the absorption of glucose (by inhibiting the absorption of two types of sugars, namely sucrose and maltose). The leaves also inhibit several enzymes that convert carbohydrates into glucose during digestion, which would be useful for people with type-2 diabetes mellitus.

2. Helps in treating diarrhoea

In different parts of the world, guava leaf tea has been used in traditional medicine to manage conditions like diarrhoea. According to several lab studies, it was observed that diarrhoea was cured quickly after administration of guava leaf tea, which inhibited the growth of Staphylococcus aureus bacteria, a common cause of diarrhoea. It also helps alleviate abdominal pain and reduce watery stools.

3. Aids weight loss

Guava leaf extract has the capacity to inhibit different enzymes that convert carbohydrates into  glucose, thereby promoting weight loss. Moreover, it is low in calories and therefore works as a good replacement for high sugar beverages.

4. Anti-microbial properties

Studies point out the anti-bacterial and anti-fungal properties of guava leaf extract. Several compounds in the leaf — including flavonoids, tannins, and acids — contribute to the antimicrobial properties and help treat gastrointestinal issues.

5. Lowers Cholesterol

According to a few lab studies, it was found that guava leaf tea has the capacity to help in lowering the LDL (low-density lipoprotein) cholesterol, also known as “bad cholesterol”, as well as triglycerides, while keeping the good cholesterol in balance.

According to a study published in ‘Nutrition & Metabolism’ in February 2010, people who drank guava leaf tea had lower total cholesterol, low-density lipoprotein levels, and triglycerides after eight weeks, whether or not they were receiving medical treatment to lower their cholesterol levels.

6. Boosts immunity

As a rich source of Vitamin C, guavas help boost immunity or maintain a healthy immune system. Their antimicrobial properties also help in preventing different types of infections caused by bacteria and viruses.

7. Relieves menstrual cramps

One study has found that drinking guava leaf tea during a woman’s period helped reduce painful cramps. The study also points out that guavas were effective or more potent than some painkillers.

Here’s a recipe to make the healthy tea:

  • Wash four big fresh guava leaves (serves one)
  • Heat one cup of water in a pan and add guava leaves to it.
  • Let it boil for five minutes.
  • Strain the leaves out and squeeze half a lemon into the water.
  • Add some honey as per taste.
  • Mix it well.
