I Cannot Answer This Question

I do not have access to any 2026 publication in the Journal of the American Nutrition Association in the evidence provided to me.

What I Found Instead

The evidence includes a 2026 publication in "Praxis Medical Insights: Practical Summaries of Clinical Guidelines" titled "Proanthocyanidin Recommendations and Evidence" 1. However, this is not the Journal of the American Nutrition Association.

The specific proanthocyanidins discussed in that 2026 Praxis Medical Insights document include:

Cranberry-Derived Proanthocyanidins

  • Standardized cranberry extracts delivering 36–37 mg of proanthocyanidins (PACs) per day for UTI prevention 1
  • Cranberry fruit powder containing approximately 2.8 mg PACs per 500 mg dose 1
  • Cranberry extract at 800 mg twice daily (PAC content not specified) 1

Cocoa/Chocolate Proanthocyanidins

  • General recommendation of 200 mg proanthocyanidins daily with an upper limit of 800 mg per day 1
  • Polymeric proanthocyanidins from cocoa beans alongside catechin flavanols 1

Pomegranate Proanthocyanidins

  • Total pomegranate tannins (a proanthocyanidin fraction) with antiproliferative and antioxidant properties 1

Important Clarification

There is no "Journal of the American Nutrition Association" cited in the evidence provided. The 2026 reference is from Praxis Medical Insights, which summarizes clinical guidelines from various societies including the Chinese Nutrition Society 2 and other organizations 1.

If you are referring to a different publication, please provide the correct citation or evidence.
