How It Works

How to Estimate Juice Nutrition

Formulas

Juice Volume = Produce Weight x Yield %

Calories = Juice Volume x Calories per 100 mL / 100

Juice Yields

  • Citrus: ~70% juice yield
  • Apples, carrots: ~60%
  • Leafy greens: ~50%
  • Watermelon: ~80%

    • Juicing removes most fiber, so juice is higher in sugar per serving than whole fruit.

    Worked Example

    Juice 300 g of apples.

    produce_weight_g = 300juice_yield_pct = 60cal_per_100ml = 46
    1. 01Juice yield: 300 x 60% = 180 mL.
    2. 02Calories: 180 x 46/100 = 82.8 kcal.
    3. 03Approx. sugar: 180 x 0.1 = 18 g.

    Frequently Asked Questions

    Is juicing healthier than eating whole fruit?

    Whole fruit is generally healthier because it retains fiber, which slows sugar absorption and aids digestion. Juice concentrates sugar without the fiber.

    How much juice does 1 lb of produce make?

    About 200-350 mL depending on the produce type. Water-rich fruits yield more juice.

    How long does fresh juice last?

    Fresh juice is best consumed within 24 hours. It can last 48-72 hours in an airtight container in the fridge. Cold-pressed juice lasts slightly longer.
