Excited to see our metabolomics analysis of beef and a plant-based alternative is now published. https://t.co/IbkYgC1GIl Despite comparable Nutrition Facts panels, we found that important differences exist. A thread summarizing its main findings 👇 1/

Working on method optimization to measure biotin on our @SCIEXFood QTRAP 7500 @USUAggies. I can confirm that there is definitely biotin in @CelsiusOfficial's Energy Drinks🤪 Biotin standard in upper pane, @CelsiusOfficial in lower pane.

First paper from our @SAREProgram Pastured Beef Project with @SierraNYoung now published! The study found that rotationally grazed, perennial grasslands🌱 had healthier soil conditions compared with neighboring fields producing commodity corn for feedlot finishing.🌽

It was a pleasure to serve on the Sustainability and Food Systems Panel with Olivier Jolliet and Adam Drewnowski at the #IDFWDS2023 moderated by @StephanPetersNL. We may not agree on everything, but constructive discussions and disagreements are a vital part of moving science

Happy to share our latest publication in collaboration with @vanvlietphd ! We measured fatty acids and #phytochemicals in 🥩 finished on grass🌱, grain🌽, and/or supplemented with 🍇. Here is what we found: https://t.co/BsrdixfIIC

Grass-finished beef (GFB) can provide beneficial bioactive compounds to healthy diets, including omega-3 polyunsaturated fatty acids (n-3 PUFAs), conjugated linoleic acid (CLA), and secondary...

This was a real fun discussion with @realJohnKempf about agro-ecology/regenerative agriculture and its effect on the nutrient density of foods🥩 🌱!
Dr. van Vliet focuses on the effects of primary and secondary compounds on the body. In this episode, @realJohnKempf and @vanvlietphd discuss nutrient differences in grass-fed beef, soil health, and more! 🎧 https://t.co/H3hk9zKQcI

The analysis for fatty fish also included “processed” fish products that contained added sodium, sugar, preservatives etc. As always the matrix as well ad overall diet in which individual foods are consumed matter.

This paper nicely illustrates the nuances of epidemiological associations. High processed red meat associated with increased mortality and cancer. Red meat is not, but then fatty fish is associated with higher all cause mortality, which is unusual and perhaps confounding. As with

There is actually some caffeic acid in meat and milk too, especially when animals are out on pasture as this compound is ubiquitous in 🌱. As with many phytochemicals, it can have health benefits at moderate doses while being “toxic” at high doses (which are unlikely to be
AVOID CARROTS It contains Caffeic acid, a natural plant pesticide. Caffeic acid is clastogenic (DNA damage). It’s also full of phytoestrogens. This causes hormonal imbalances, low sperm count and infertility. Anything that can turn you orange, you just shouldn't eat. AVOID.

Remember the headlines that eating a hotdog 🌭 takes 36 minutes of your life and that a PBJ 🥪 add 32 min to your life. Our friendly critique of the study is now published👇 Assuming causal outcomes between single foods and health, we think…, is a bit much. What if we eat an

“Scientists Build a Healthy Dietary Pattern Using Ultra-Processed Foods” The scientists didn’t actually test health outcomes in a study. To me this work simply suggests that you can “game” the healthy eating index and create a diet with a high score based on simplified metrics.

Enjoyed visiting several of the Turner Bison Ranches and speaking at their Summer meeting. The biodiversity and birdlife🐦 at the 🦬 ranches is particularly impressive, birds are literally everywhere! Another impressive effort is the accommodation for other wildlife🦌by

Enjoyed the interview with DECENTRALIZED RADIO. In the clip below, we discuss metabolomics and fatty acid results comparing grass-fed and grain-fed bison 🦬 and beef 🐄 with a potentially favorable shift in saturated fatty acid profiles with grass-finishing👇 Paper found here:

Caffeine also associated with higher animal protein intake, but that is probably because “meat-eaters” drink more coffee☕️ What is nice about this work is the linking of dietary recalls with metabolite data. https://t.co/w5yMjb49d5

The results of 17 of the 41 metabolites (41%) were consistent with those of previous nutritional metabolomic studies and specific protein-rich food items. We discovered 24 metabolites that had not...

Nice metabolomics works from the ARIC cohort on compounds in the blood—>protein intake. Phenolic metabolites such catechol, vinylphenol, hippurate, and the omega-6 LA⬆️with plant protein🌱 Creatine, B6, and DHA⬆️with animal protein 🥩 My pet peeve is that both provide

We have also noticed that chicken thighs 🍗 are richer in b-vitamins, phenols, terpenes and other anti-oxidants as well, compared to breast meat. More blood flow to thighs as opposed to breast is more nutrient delivery to the thighs! Cheaper and tastier too! (IMO)
Nice to see metric results from my PhD work many years ago being confirmed by a world leading nutritional scientist! Really interesting that dark poultry meat is denser too, didn’t know that. Do the white vs. dark meat results include limited fatty acids, @TyRBeal?

Enjoyed my recent podcast with @bitcoinand_beef and @KetosisRyan in person in SLC! We talked about our recent metabolomics paper on grass-fed and grain-fed bison and linking animal health and human nutrition! Podcast and paper below 👇 https://t.co/aNnKeVilRd
