Our take

CleanPlate review

Whole wheat and rice bran oil in a sweet biscuit

Open Secret's digestive is made from whole wheat flour, rice bran oil and coarse wheat bran. It is sweetened with pulverised sugar, liquid glucose and malt extract and finished with skimmed milk powder and a milk, vanilla and ghee flavouring.

CleanPlate scores it CB3. The C for nutrition is middling: 6.5 g fibre per 100 g; its 7 g of protein earns no credit because it is under 2.75 g per 100 kcal. The B for ingredients reflects a mix of whole and refined ingredients (led by whole wheat flour, rice bran oil and coarse wheat bran), with additives that cost points: sodium metabisulphite. The 3 for risk comes mainly from saturated fat (6 g per 100 g) and free sugar (11 g per 100 g).

A closer look

Does the label add up?

Whole wheat flour, rice bran oil, coarse wheat bran, pulverised sugar, liquid glucose, malt extract, soy lecithin, "Solbake", skimmed milk powder, salt, raising agent (ammonium and sodium bicarbonate), the antioxidant sodium metabisulphate and natural and nature-identical flavourings. No percentages are declared.

Per 100 g: 484 kcal, 19.5 g fat of which 6 g saturated, 13 g sugar of which 11 g added, 6.5 g fibre, 7 g protein, 110 mg sodium. The antioxidant is printed "sodium metabisulphate"; we read it as the sulphite sodium metabisulphite (INS 223). "Solbake" is listed without explanation.

Ingredients to watch

  • Sulphite antioxidantWorth watching

    Sodium metabisulphite can trigger asthma and allergy symptoms in sensitive people.

  • Three forms of sugarWorth watching

    Pulverised sugar, liquid glucose and malt extract give 11 g of added sugar per 100 g.

  • Saturated fatWorth watching

    6 g per 100 g; rice bran oil brings less than palm-oil biscuits usually do.

  • Whole wheat and bran leadFine

    The first and third ingredients are whole wheat flour and coarse wheat bran.

Common misconceptions

Myth: "Digestive biscuits help digestion"

The name is historical. Fibre helps, and 20 g (one serve) gives about 1.3 g of it.

Myth: "No palm oil means low in saturated fat"

Rice bran oil still contributes 6 g of saturated fat per 100 g; the pack has 19.5 g of fat per 100 g.

How often, and how

  • Healthy adultsA few times a week
  • ChildrenOccasionally
  • Diabetes or prediabetesOccasionally, watch the sugar

Smarter ways to eat it

Pair with protein

A biscuit or two with milk, curd or nuts makes the snack more filling.

Check the sweet

If you want less sugar, choose a pack with under 5 g of added sugar per 100 g.
