I saw this a few days ago.
"She was a “gluten-free, sugar-free, oil-free, grain-free, legume-free, plant-based raw vegan”."
"But the “clean” diet that Younger was selling as the route to health was making its creator sick. Far from being super-healthy, she was suffering from a serious eating disorder: orthorexia, an obsession with consuming only foods that are pure and perfect. Younger’s raw vegan diet had caused her periods to stop and given her skin an orange tinge from all the sweet potato and carrots she consumed (the only carbohydrates she permitted herself)."
She wasn't just suffering from orthorexia; she was suffering from malnutrition. No oil or butter or other fat means the body cannot absorb vitamins A, D, E or K. The body also needs carbohydrates to survive. Her periods stopped because her eating habits could not sustain her own body, much less that of a possible child.
This is why I have always hated the term "clean eating." It implies that any other way of eating is dirty and wrong and can lead to this kind of extremism, or guilt that you're not living like this.
