Guava is an incredibly delicious and nutritious tropical fruit. Low in calories and loaded with fibre, it is an excellent addition to a healthy diet. The fruit can be taken in several ways- have it raw, turn it into a tangy chutney, make sweet jam or cook it, it will all taste delicious. Not only the fruit, but guava leaves are also extremely beneficial for health. Studies suggest that adding guava leaf extracts to the diet may boost your heart health, digestion, and immune system. But there are some compounds in this fruit, which is not considered good for all, especially those suffering from specific health conditions.
