Why is white bread forbidden but bran toast permitted?
White bread vs bran toast
What the system says
The system frames white flour as the leading cause of digestive disease, claiming it "turns into a sticky paste" in the stomach that damages the mucosal lining. Bran toast is exempt because it contains a higher proportion of bran and isn't subjected to the same kneading process.
What science says
The "sticky paste" claim isn't scientifically accurate — digestive enzymes break down starch effectively. The real difference: whole-grain bread has more fibre, B vitamins, and iron, raising blood sugar more slowly. Either, in moderation, can be part of a healthy diet.
Picking bran toast over white is a reasonable healthy choice — but not because white is "dangerous." To diversify your starches, rice, potato, and oats (despite the system's ban) are all good options.
