Since the rise of SM and youtube, etc, there are never ending streams of 'experts' espousing some new rule or pseudo science about nutrition and weight loss.
Some examples I have seen both on here and elsewhere online:
"If you have IBS then never eat protein with carbs at any meal"
"I lost 4 stone just doing yoga" (with added picture of dramatically photoshopped waist).
"Going vegan cured my rosacea, acne, anxiety" (So most teens and adults with skin issues just need to quit animal products and voila!).
"Bread is death". (enough said).
"Most people cure IBS by going dairy free, gluten free, etc" (er no, not me, mine is stress related and down to food complexity, not type)
"A fully plant based diet cures gut issues" (but can actually cause some, especially leafy veg and salad greens)
It's all about populism isn't it? One young woman I found on youtube last night looking into IBS had achieved 300K followers in a year just sitting in front of the camera looking attractive and telling everyone what they ought to quit eating. Which was nearly everything that didn't come in a vegan franken-packet from Waitrose. I imagine a lot of young people idolising this are either overweight or suffering pain, and are convinced they will look like her and gain her lovely, terrifyingly clean apartment if they simply switch their diet up.
Surely it's all bollox? We know many people cure gut issues via eliminating certain foods, and that's natural. But there is so much contradictory, populist rubbish floating about that feels as if it is an ego boost to the creator rather than any practical use at all.
