Basic Information: Guava is a common tropical fruit cultivated in many tropical and subtropical regions. Widely cultivated in tropical and subtropical regions around the world, guava fruits can range in size from as small as an apricot to as large as a grapefruit. Various cultivars have white, pink, or red flesh, and a few also feature red (instead of green or yellow) skin. Guava fruits, usually 4 to 12 centimetres (1.6 to 4.7 in) long, are round or oval depending on the species. They have a pronounced and typical fragrance, similar to lemon rind but less sharp. The outer skin may be rough, often with a bitter taste, or soft and sweet.

Health Benefits:

  1. Antioxidant Properties – The naturally high content of vitamin C in guavas, four times higher than that found in oranges, helps boost the immune system.
  2. Controls Diabetes – The intake of guava can also help patients suffering from diabetes. It contains a high level of dietary fiber, which has a beneficial effect on lowering blood glucose levels in the body.
  3. Regulates Blood Pressure – Research published in the American Journal of Cardiology found that guava helped reduce LDL cholesterol levels and blood pressure in study participants.
  4. Improves Thyroid Health – Guava is a good source of copper, a mineral important for regulating metabolism by helping to control hormone production and absorption.
  5. Eliminates Diarrhea & Dysentery – Whether you chew on its leaves or eat the raw fruit, the astringent qualities add substance to loose bowels and reduce the symptoms of diarrhea.
  6. Relieves Constipation – Guava is one of the richest sources of dietary fiber amongst fruits, and its seeds serve as excellent laxatives.
  7. Improves Brain Health – Another tremendous benefit of guava is the presence of B vitamins, B3 and B6. Vitamin B3 (also known as niacin) can increase blood flow and stimulates cognitive function, whereas vitamin B6 is a nutrient correlated with brain and nerve function.
  8. Weight Loss – Guava is very helpful for people wanting to lose weight without compromising their intake of vital proteins, vitamins, minerals, and fiber. It is high in roughage (fiber), has no cholesterol and contains a low number of digestible carbohydrates.
  9. Skin care – Guavas can improve the health of your skin and help you avoid skin problems. This is chiefly due to the abundance of astringents available in the fruit.

Fun facts:

  • Unlike many types of fruit, cultivating guavas does not require much use of pesticides. They are among the least chemically-treated fruits in the world today.
  • Guava trees are not only prized for the fruits that they bear but also for their wood. Guava wood has an aroma that can be described as semi-sweet, which makes it ideal for smoking meat, poultry and fish.
  • At one point in Philippine mythology the guava was forbidden. This changed when a child prayed to the gods to make the inedible fruit delicious so he could feed a beggar.
