There are innumerable benfits of having guavas during pregnancy. It is one of the richest sources of Vitamin C, a nutrient that acts as an immunity booster in pregnant women, who tend to be susceptible to infections. It is also a good source of dietary fibre. Just 1 guava fulfills about 12% of your daily recommended intake of fibre, which makes it extremely beneficial for your digestive system. Guava seeds, if ingested whole or chewed, serve as excellent laxatives too, helping in bowel movements.
