Useful facts when choosing a product

  • The intervention was a drink made from 50 g freeze-dried whole-strawberry powder, not fresh strawberries.
  • Modern cultivated strawberry, Fragaria × ananassa, is an eighteenth-century European hybrid and is a different genus from Rubus fruits called 「覆盆子」 in East Asia.
  • Verdict 1981 is C with 40 points for whole raw apples and LDL; the endpoint is the same but the food and form differ.

What the research actually shows

Huang and colleagues reported a randomized double-blind crossover trial completed by all 34 participants. The California Strawberry Commission funded the study and supplied both strawberry and control powders. The comparator was matched for energy and volume.

Why this is classified as D (28)

The registered LDL surrogate was null in one industry-supported trial. The trial was small and short, and no between-condition confidence interval for the null result was available, yielding D with 28 points.

Counterpoint. The matched control and prospective registration strengthen confidence in the null finding.

Chamgap is an information source. It reports what research has and has not confirmed; it does not tell readers what to take or buy.
