A single 55-gram guava contained 37.4 calories, 1.4 grams of protein, 0.52 grams of fat, 7.88 grams of carbohydrates, 2.97 grams of fibre, and 44.44 grams of water. The fruit also included vitamin C, vitamin A, vitamin E and essential minerals such as calcium, potassium, magnesium, sodium, and zinc.

Nutrition experts stated that guava had been recognised for its antioxidant richness, which protected the body from damage caused by free radicals, a key contributor to health deterioration.

According to medical sources, guava helped diabetics in several ways. It assisted in the control of blood sugar levels and increased cell sensitivity to insulin in cases of insulin resistance. It also addressed constipation, a frequent condition among diabetics, due to its high fibre content. The fruit’s low sugar concentration and antioxidant presence contributed to blood sugar reduction, while guava leaf tea improved blood sugar levels and insulin resistance over time.

Specialists indicated that guava leaves contained an abundance of antioxidants that played a vital role in the prevention of cancerous growths. These compounds, including vitamin C and lycopene, helped prevent the spread and development of cancer cells. Among the cancers guava assisted in preventing were breast cancer, prostate cancer, and colorectal cancer.

In the context of cardiovascular health, guava improved blood pressure through its potassium content and contributed to heart health maintenance. It reduced harmful LDL cholesterol levels while raising beneficial HDL cholesterol, thus aiding in the prevention of cardiovascular disease. The antioxidants and vitamin C within guava protected heart cells from oxidative damage and enhanced heart function.

Guava played an effective role in weight loss as well. The fruit remained low in calories, low in fat, and rich in water, which helped in body hydration. The fibre content promoted digestion and prolonged satiety, which proved beneficial during weight management. Furthermore, the fruit’s composition of essential vitamins and minerals supported the body’s nutritional requirements throughout the weight loss process.

In relation to immunity, guava emerged as a major source of vitamin C, providing twice the recommended daily intake in one fruit. The vitamin improved immune system performance, reduced inflammation, and protected body cells from free radical damage. Guava’s antioxidant compounds, including lycopene, further enhanced immune responses and defended the body against microbial threats. It eliminated bacteria and viruses, safeguarding the body from diseases and infections.

Guava contributed to digestive health by improving digestion through its dietary fibre. It treated constipation effectively and stimulated bowel movements due to its seeds acting as a natural laxative. It also addressed diarrhoea and protected the stomach from infections, as both the leaves and fruit held anti-inflammatory and antibacterial properties.

Dermatologists said that guava played a key role in maintaining youthful skin. It regenerated skin cells and improved elasticity through its high vitamin C content. The juice offered hydration benefits, while guava leaf extract served as a topical remedy for pimples and acne due to its antibacterial nature.
