Health Benefits of Banana

Bananas are an excellent source of potassium, which supports heart health and proper muscle function. They contain vitamin B6, which plays a key role in brain health and neurotransmitter synthesis. The resistant starch in unripe bananas acts as a prebiotic, feeding beneficial gut bacteria.

How to Track Banana Accurately

Accurately tracking banana requires knowing both the exact weight and preparation method. Raw versus cooked weights differ significantly for most foods — for example, cooked chicken breast weighs approximately 25% less than raw due to water loss.
