How it fits into a day

A small cucumber of about 150 g has only about 25 kcal, because it's almost all water. In a salad the calories come from the oil and sour cream, not the cucumber. Carbs provide about 75% of the calories.

A usual serving (1 small cucumber) is about 1% of a 2,000 kcal day. How much do you need a day? Work it out in the calorie calculator.

Lighter options

  • Cucumber and a piece of white cheese make a light dinner.
  • Tarator and tzatziki have more calories because of the yogurt and oil, so count them separately.
