www.intensivedietarymanagement.com
Problems with Wheat
1. Modern wheat is of lower
nutritional value
2. Modern processing removes
most of vitamins, fibre and
fats
3. Modern milling (as opposed
to stone ground) increases
speed of digestion
4. High in amylopectin A
(highly digestible)
5. May be addictive
