Q

how is fat digested

A

what can you substitute instead of gluten
instead of- wheat, rye and oats you can use- rice, coy and potatos
36

37
what can you substitute instead of lactose
instead of- dairy products use-soy dairy products and rice milk
38
what is FODMAP
a group of short chain carbs including fructose, lactose that are poorly absorbed by the small intestine, FODMAPS foods draw water when going through the large intestine, then bacteria uses these short chain carbs as food =s which releases gasses
39
examples of FODMAPS foods and what to substitute
examples- asparagus, onions and garlic subs- eggplant, boc choy, orange
40
what are the 3 principles of research
recognition of credible sources: food experts from around the world, food industry experts, everything carefully referenced evidence based information: 55,000 pieces of published scientific research, systematic literature review, controlled testing accurate analysis of data: analysed the 55,000 bits of research and gotten advice from a wide range of experts
41
what is food citizenship
