Cucumber

Cucumber

Overview​

Cucumber provides water, vitamin K, modest vitamin C, and very low energy density [1]. As a hydrating vegetable, it supports volume and phytochemical diversity within plant-forward patterns [2].

Within the BRAIN Diet framework, cucumber is a low-calorie hydration vegetable; peel-on varieties add fibre and polyphenols.

Key Nutritional Highlights​

  • Vitamin K in whole-cucumber preparations with peel [1].
  • Supports meal volume and hydration in plant-forward patterns [2].
  • Pair with fat-containing dressings when co-ingesting fat-soluble nutrients from salads.
