Good morning! Starting day 2 with another of my favorite #nutrition topics: the food matrix. What does that mean for #health? Food is not simply the sum of its parts. 🤓
#Nutrition2022 #NutritionLiveOnline Image
First up, one of my colleagues in nutrition and the #gut #microbiome, @HolscherLab. Let's #science!
#Nutrition2022 #NutritionLiveOnline Image
The matrix of foods affects the bioaccessibility of nutrients.
#Nutrition2022 #NutritionLiveOnline Image
How foods are processed affects the food matrix and thus the bioaccessibility of nutrients in the food. #Nutrition2022 #NutritionLiveOnline Image
This means that the food label (simply what the food contains) is not enough to understand what the body will be able to utilize (bioaccessibility). #Nutrition2022 #NutritionLiveOnline Image
Nuts are a great example of how the food matrix greatly affects the bioaccessibility of nutrients. #Nutrition2022 #NutritionLiveOnline Image
The less processed the nuts, the less bioaccessibile the nutrients. #Nutrition2022 #NutritionLiveOnline Image
Making the nutrients more bioaccessibile for the host (us) makes them less accessible to the #gut #microbiota. This affects the composition of the #GutMicrobiome. #Nutrition2022 #NutritionLiveOnline Image
Another example is how calcium in a food alters the bioaccessibility of fat in foods. This may be why dairy seems to contribute fewer Calories to the diet than we would predict. #Nutrition2022 #NutritionLiveOnline Image
Fermentation of dairy can further alter the food matrix, leading to potential health benefits. This is why yogurt appears to be beneficial in numerous studies even when dairy does not. #Nutrition2022 #NutritionLiveOnline Image

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Starting the talks with some unpublished work from USDA and Baylor.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
