«Sugar and gluten are poison that must be eliminated no matter what»
Nuanced
What the evidence says
Gluten is only a problem in coeliac disease or genuine sensitivity. Sugar is not 'poison': the problem is excess calories and crowding out nutritious foods. In a diet with enough protein and fibre, at maintenance or in a deficit, some sugar fits without drama.
How settled this is
Dose and calorie context matter more than demonising a nutrient.
