Probably the best value fruit in South Asia — more vitamin C than orange, more fibre than most.
Guava is underrated everywhere it is not already a staple. It contains several times the
vitamin C of an orange, roughly three times the fibre of an apple, and it is usually among the
cheapest fruits in the market.
Pink guava also contains lycopene, the carotenoid more
famously associated with tomatoes.
The seeds are edible and are a meaningful part of
the fibre. People who scoop them out are removing much of the reason to eat it.
Per 100g. Vitamin C content is roughly four times that of an orange.
Based on the nutrients and fibre this food supplies. These are supporting foods, not treatments.
Eat the seeds. They are most of the fibre. Chew or swallow — either
works.
Slightly firm is better than fully soft. Overripe guava turns
mealy and loses the acidity that makes it interesting.
Salt and chilli
is not just a street food habit — it genuinely lifts an underripe
guava.
Eat it with iron-rich food. Guava alongside dal or spinach
substantially increases how much of that iron you absorb.
Guava's vitamin C content is high enough that a single fruit covers several times the
daily requirement. The practical value of that is not immune boosting — it is iron
absorption. Vitamin C converts plant iron into a form the gut absorbs far more readily, and
that effect is dose-dependent within normal food amounts.
In a region where iron
deficiency anaemia is common and diets are largely plant-based, eating a cheap high-vitamin-C
fruit alongside meals is one of the more useful habits available.
Diabetes: whole fruit over juice, portion aware, and better eaten
with protein or fat than alone.
IBS: several fruits are high-FODMAP
and commonly trigger symptoms — tolerance is personal.
Kidney
disease: potassium may need limiting. Ask your doctor for your numbers.
