Nutrition researcher and coauthor of a 2026 study on genetic modifiers of diet score and LDL cholesterol.
In young adults, higher PDS and intake of its components showed favourable associations with LDL-C. Our findings suggest that ABCA1 rs1883025 and ABCG8 rs6544713 genotypes modify the association of the PDS, plant protein and phytosterols with LDL-C.

Disputed The quote text is real and appears verbatim in the article’s Conclusions on the publisher page, and a secondary index linked to PMID 42323221 shows the same wording and the full multi-author byline. However, this is a multi-author journal article, so attributing the passage to John L. Sievenpiper alone is a misattribution under this platform’s single-author rule; additionally, the submitter-provided PubMed passage does not itself contain the quote, and the PubMed URL was not directly fetchable here because of a browser check.
