Currently, one of my family members frequently sees a lot of conflicting nutrition and medical info on the internet with various influencers, so it can be hard for them to decipher what’s true or not. Are there any channels with easy to understand shorts, that also meet the general scientific consensus?


You can’t have one without the other. Nutritional research is severely lacking in the literature. any of the cited studies that make the vast bulk of the scientific flotilla are just observational epidemiology… Which is very noisy.
I’ve done a bunch of reading, a massive amount really, and the only thing everyone agrees about is processed foods are bad… Except not all processed foods (the ones that further some other agenda)
Pick your flavor of opinion and people can suggest good creators in that vertical.
Personally - After all my reading I’ve settled on keto/carnivore, but to say there isn’t consensus is a understatement. There are many people who make their diet their identify and feel personally attacked if you eat differently than them. The best thing I can say for keto is their evidence is consistent, lines up across domains, and individuals following it see immediate improvements in their health metrics
I can recommend the low carb down under YouTube channel for medical lectures on the keto, very clear about the quality and limitations of their evidence.
