It's happening now! #GreatDebates in #Nutrition on ultra-processed foods and the Dietary Guidelines. 🤓 #Nutrition2022 #NutritionLiveOnline Image
Ultra processed foods are an emerging interest in #nutrition #science. They have been linked to numerous negative #health outcomes. Image
This #GreatDebate will attempt to tackle the role of ultra processed foods in health/disease, confounding, etc.
#Nutrition2022 #NutritionLiveOnline Image
Now for the "yes, ultra processed foods are problematic" side of the debate. #GreatDebateNutrition Image
What are ultra processed foods? The Nova classification system is the general consensus, which is based solely on the processing of the foods. Image
There are markers you can use to identify ultra processed foods Image
The amount of ultra processed foods in the diet have increased over time. 😱
#Nutrition2022 #NutritionLiveOnline Image
What does the increasing prevalence of ultra processed foods do to the diet? Increased added sugar, decreased fiber. 👎👎 #Nutrition2022 #NutritionLiveOnline Image
30 cohort studies link ultra processed foods to numerous disease states even after adjusting for potential confounding. #Nutrition2022 #NutritionLiveOnline Image
Many meta analysis confirm this including for the very important all-cause mortality. #Nutrition2022 #NutritionLiveOnline Image
The imbalance of dietary nutrients with the introduction of more ultra processed foods is part of the effect--mediators, not confounders. #Nutrition2022 #NutritionLiveOnline Image
It's more than just nutrient imbalance in ultra processed foods. They are missing health promoting components (phytochemicals) and contain potentially harmful ones like additives. Image
Or should we recommend that discontinuation of ultra processed foods (like stopping smoking) before the exact mechanism is clear? #Nutrition2022 #NutritionLiveOnline Image
The rebuttal: Processing is really poorly defined, as are the ingredients. #Nutrition2022 #NutritionLiveOnline Image
There's no threshold for these ingredients. How can we define the problem? #Nutrition2022 #NutritionLiveOnline Image
Is ultra processing just a marker of a poor diet? Add that to the problematic classification and what are we really studying? #Nutrition2022 #NutritionLiveOnline Image
We might be able to explain the negative effects of ultra processed foods by traditional nutrition characteristics as well? #Nutrition2022 #NutritionLiveOnline Image
The debate is heating up now! #Nutrition2022 #NutritionLiveOnline
Another #GreatDebateNutrition in the books. I love seeing my colleagues debate hot topics in a rigorous and collegial manner. Looking forward to the publication! #Nutrition2022 #NutritionLiveOnline

My last live session (still tons of on demand to go)! We'll be looking at the role of #nutrition and #epigenetics in health and disease. #Nutrition2022 #NutritionLiveOnline
Starting the talks with some unpublished work from USDA and Baylor. #Nutrition2022 #NutritionLiveOnline
What is epigenetics? It's alterations of the genome that support or silence gene expression. #Nutrition2022 #NutritionLiveOnline

You've heard of #IntermittentFasting, but do you know the science? That's where @nutritionorg comes in! The next session features @DrKristaVarady, @LongoOnlus, @SatchinPanda, & @Kelsey_Lifts. #Nutrition2022 #NutritionLiveOnline
First alternate day fasting and time restricted eating (TER). #Nutrition2022 #NutritionLiveOnline
There are 3 types of intermittent fasting: alternate day (ADF), 5:2, and TRE. What do clinicians fear about ADF? Binging. #Nutrition2022 #NutritionLiveOnline

Not so patiently waiting for the next session. 🙃 Can't wait to dive into dietary protein and muscle metabolism in healthy aging! #Nutrition2022 #NutritionLiveOnline
This session is in honor of a recently lost colleague. What a beautiful legacy. #Nutrition2022 #NutritionLiveOnline
One of the key takeaways from Dr. Paddon-Jones's work is that the American style of eating--backloading protein--is problematic for muscle protein synthesis. The most catabolic period is after the overnight fast. #Nutrition2022 #NutritionLiveOnline

Kicking off day 3 with more on ultra processed foods (a theme?). This time in the context of #PlantBased diets (aka plant-centered) and how we can increase plant intake while avoiding ultra processing. #Nutrition2022 #NutritionLiveOnline
First talk, "What are 'utra-processed' foods?" Seems like a good place to start the conversation. #Nutrition2022 #NutritionLiveOnline
The classification system for ultra processed foods is NOVA. Is NOVA about nutrients? Well, this seems to be. #Nutrition2022 #NutritionLiveOnline

Now we'll talk #polyphenols and #PrecisionNutrition in this next science packed session at #Nutrition2022. #NutritionLiveOnline Image
Oh look the #microbiome is here too! 🥰👏🥳 Yes, polyphenols are key to the #GutMicrobiome. Let's learn more.
#Nutrition2022 #NutritionLiveOnline Image
But first the #metabolome and polyphenols. #Nutrition2022 #NutritionLiveOnline Image
