About these values

The record is a raw banana, and the portion weights are for the fruit without its peel. The USDA record is "Bananas, raw" (SR Legacy, FDC ID 173944). It gives 1.09 g of protein and 89 kcal per 100 g.

Protein in a portion is its weight times the protein per 100 g, divided by 100. For 1 medium banana: 118 × 1.09 ÷ 100 = 1.3 g. Values on this page are rounded to 0.1 g.

A packaged food's own label can differ from the USDA average. When you have the label, its numbers are the ones for that product.
