Vitamin B12 is a rather unique vitamin.

Only certain bacteria and archaea can make it, not plants or animals.

Animals require B12 and can obtain and store it, which is why meat and fish are well-known sources for humans.

But what about non-animal foods? Can they provide any B12 at all?🧵⤵️

In this US study, people with a college degree were more likely to consider or choose plant-based burgers than those without a degree.

But when the prices of plant-based options were lowered, consumers without a college degree became more inclined to buy them.

Very cool new study & great datasets.
The authors compared the nutritional composition and density of plant-based meat alternatives vs. meat.

They write: plant-based meat is equally nutrient-dense as animal meat and legumes.

It only took me 500 years to finish this 📊, but here it is 🎉

Grocery shops in many wealthy countries are oversupplied with animal-based foods. They stock far more meat and dairy than we need for human and planetary health.

In South Africa, when people move to cities, their diets become similar to a “Western” one, with more energy-dense foods, animal protein, and fat.

This shift changes the diversity of gut microbes, increasing bacteria previously linked to higher colorectal cancer risk.

Important new study:

Animal products, especially beef, pose much higher extinction risks for wildlife than grains, legumes, or vegetables. This means shifting land use toward more plant-based diets can give greater opportunities to restore biodiversity and help save species from extinction.

Even with a genetic predisposition, not everyone will develop dementia. Various factors play a role.

This study suggests that people who are APOE4 homozygotes, the group at highest genetic risk, may benefit the most from following a Mediterranean diet.

🧪 Amazing study describing a workflow that will help us better understand the lipid biology of mammalian cells.

Check out this very informative 🧵⤵️
Out today in @nature.com: Together with the Honigmann, Shevchenko, Drobot and Hof labs, we present a general workflow for imaging the localization and transport of individual lipids in cells and mapping their metabolism.

🧪 In this cool study, researchers used advanced 4D imaging to visualize mechanical forces during human embryo implantation.

Lots of interesting movies.

Here, two embryos form a mechanical "bridge", they can feel and pull on each other!

Plant vs. animal protein for muscle health:

✔️ Slightly lower muscle mass with non-soy plant protein compared to milk protein, but not with soy
✔️ No difference in muscular strength or physical performance

No wonder there are elite athletes who are vegan.

Short-chain fatty acids are not the only metabolites produced by gut microbes fermenting dietary fiber. Other bioactive molecules such as amino acids and B vitamins can be produced too.

Understanding their effects may help explain why people respond differently to fiber.

Would making healthy foods a bit cheaper and placing them in better spots in supermarkets help people buy fewer ultra-processed foods?

This study showed that it didn’t.

Perhaps limiting the promotion of ultra-processed foods is a better strategy?

I’ve been learning React.js lately and made this 📊.

It shows the protein & fiber content of processed foods commonly found in grocery stores.

These nutrients are great for promoting satiety and may help reduce the risk of overeating (PMID: 35592279).

In 1975, a fellow Cornell grad student gave a presentation of Burkitt's work at a brown bag lunch seminar. The faculty poo pooped it while munching on their balcony on white bread. I stopped eating white flour and never went back.

💦Hydration might be a simple yet effective way to minimize the negative effects of sugar or salt. They can raise serum osmolality and trigger acute stress responses, e.g., a transient increase in blood pressure.

Co-ingestion with water blunts this.

Does eating ultra-processed foods CAUSES obesity?

The authors of this paper used a statistical tool called 'E value' to show that the link between eating lots of processed foods and gaining weight could be explained by other factors, such as food insecurity.
