Our take

CleanPlate review

Unsweetened oat drink with 10% oats

Only Earth Unsweetened Plant Based Oat Beverage lists water, oats (10%), sunflower oil, minerals (calcium carbonate), acidity regulator (dipotassium phosphate), salt and vitamins (D, riboflavin, B12). The pack is 1 L and the panel is printed per 100 ml, with a 200 ml serve.

CleanPlate scores it [F]CA1. The C for nutrition is middling: modest protein, fibre and micronutrients per 100 ml. The [F] marks that added calcium, vitamin D, vitamin B1 and vitamin B2 lift the grade; without them it would be E. The A for ingredients reflects whole or lightly processed ingredients (led by oats and sunflower oil), and almost no additives. The 1 for risk is low: sodium, free sugar and saturated fat are all modest (sodium 45 mg, free sugar 0 g, saturated fat 0.2 g per 100 ml).

Claims vs reality

What the pack says, checked against the ingredient list and nutrition panel.

  • On the pack

    “No added sugar & preservatives”

    Holds

    Added sugar is 0 g and no sugar or preservative is listed.

  • On the pack

    “Source of Calcium”
