Journal ArticleDOI
Impact of dietary polyphenols on carbohydrate metabolism.
Kati Hanhineva,Riitta Törrönen,Isabel Bondia-Pons,Jenna Pekkinen,Marjukka Kolehmainen,Hannu Mykkänen,Kaisa Poutanen +6 more
TL;DR: To confirm the implications of polyphenol consumption for prevention of insulin resistance, metabolic syndrome and eventually type 2 diabetes, human trials with well-defined diets, controlled study designs and clinically relevant end-points together with holistic approaches e.g., systems biology profiling technologies are needed.
Journal ArticleDOI
Disintegration of wheat aleurone structure has an impact on the bioavailability of phenolic compounds and other phytochemicals as evidenced by altered urinary metabolite profile of diet-induced obese mice
Jenna Pekkinen,Natalia Nicole Rosa,Natalia Nicole Rosa,Natalia Nicole Rosa,Otto-Ilari Savolainen,Pekka Keski-Rahkonen,Hannu Mykkänen,Kaisa Poutanen,Kaisa Poutanen,Valérie Micard,Valérie Micard,Kati Hanhineva +11 more
TL;DR: The structural modifications on wheat aleur one fraction resulted in altered metabolism of aleurone derived phenolic acids and other phytochemicals excreted in urine of diet-induced obese mice.
Journal ArticleDOI
Metabolic signature of extracellular vesicles depends on the cell culture conditions.
Mari Palviainen,Heikki Saari,Olli Kärkkäinen,Jenna Pekkinen,Seppo Auriola,Marjo Yliperttula,Maija Puhka,Kati Hanhineva,Pia Siljander +8 more
TL;DR: It is concluded that the cell culture conditions of EV production should be standardized and carefully detailed in publications and care should be taken when EVs from different production platforms are compared with each other for systemic effects.
Journal ArticleDOI
Betaine supplementation causes increase in carnitine metabolites in the muscle and liver of mice fed a high-fat diet as studied by nontargeted LC-MS metabolomics approach.
Jenna Pekkinen,Kaisa Olli,Anne Huotari,Kirsti Tiihonen,Pekka Keski-Rahkonen,Marko Lehtonen,Seppo Auriola,Marjukka Kolehmainen,Hannu Mykkänen,Kaisa Poutanen,Kaisa Poutanen,Kati Hanhineva +11 more
TL;DR: It is suggested that increased availability of BET in different tissues, especially in muscle, after BET supplementation has an impact on carnitine metabolism, and this could further explain the link between BET and lipid metabolism.
Journal ArticleDOI
The Postprandial Plasma Rye Fingerprint Includes Benzoxazinoid-Derived Phenylacetamide Sulfates
Kati Hanhineva,Pekka Keski-Rahkonen,Jenni Lappi,Kati Katina,Jenna Pekkinen,Otto Savolainen,Oskari Timonen,Jussi Paananen,Hannu Mykkänen,Kaisa Poutanen +9 more
TL;DR: The bioavailability of whole-grain rye-derived phytochemicals has not yet been comprehensively characterized, and different baking and manufacturing processes can modulate the phytochemical composition of breads and other rye products.
