96% of the feed consumed by domesticated ruminants is NOT human-edible. The grains that are fed amounts to 7% of 2018 global cereal production. #Upcycling #FoodSecurity #EssentialNutrition #SustainableFood
1/4 83% of all livestock feed is consumed by ruminants, which can utilize resources humans cannot consume directly.

The theme for #WorldEnvironmentDay2022 is "Only One Earth." Let's consider the essential role that #ruminants play in global food production and the unique ecological advantages they offer. First, what's a ruminant?
1/3 Image The vast majority of our one Earth's surface is unsuited for the production of plant source foods. But it can produce plant fiber that ruminant animals are uniquely capable of using - converting a resource humans cannot utilize into food of highest nutritive quality.

Why it's important to know what *they* mean by the phrase "nutrient dense."
The 2020-2025 Dietary Guidelines for Americans' third suggestion to "make every bite count" - Image You might think you know what they mean by "nutrient dense," but let's check. So #dairy & #meat only qualify if they're low-fat because naturally-occurring animal fats are not nutrients, per DGA. Lettuce, a vegetable, does, per DGA. Does this fit your definition? Image

So, per #ipccreport2021, the effect of enteric CH4 emissions from stable herds has been overstated (and CH4 from fossil fuels similarly underestimated).

Thread on #lysine #upcycling #ruminants
Only 4% of the feed consumed by the global domestic ruminant herd is *potentially* human-utilizable. The upcycling of the other 96% into resources that are essential to modern (& future) societies is under-appreciated. 2/9
- The grain fed represents only 10% of the global cereal production.
- 1/4 of the grain fed is off-grade & not human edible.

Herdmates, it's time to dive into the rumen and its microbiome. Not literally, of course. That would be nasty.

1/n Food for thought:
An understanding of metabolic health and a species appropriate diet hasn't informed conversations about sustainable health care. The "downstream" effects of food choices are usually informed by the received wisdom of the official "healthy diet."
What if: 2/n
So what if, just speculating wildly here, what if there was a way for people with T2D to stop using those medications? I know, that sounds like crazy-talk, but hear me out.

Big numbers and unfamiliar units are sometimes hard to visualize, so here's one equivalent:

1. More thoughts on protein in human nutrition. Remember that cereals supply a greater proportion of crude protein in humanity's diet than all animal source foods (ASF), combined. Image 2. Wheat provides almost half of that portion, a greater amount than any single ASF! Image

1. More food for thought regarding protein in human nutrition: The composition of Plant Source Foods (PSF) is more variable than that of Animal Source Foods (ASF). For example: Here's Crude Protein content of almost 6k of soybean samples... Image 2. ...and the amino acid contents of those samples. Consider the implications for food tables and labels (which are typically based on the average values listed in tables)... Image
