Feeding For Healthy Hormones Flashcards
What sites of the body are hormones for digestion produced
Fat cells
Gastrointestinal tract
Pancreas
Define Glycaemic response
The effect food has on the body’s blood glucose levels
What are some sources of easily digestible carbohydrate
Cereals
Molasses (syrups)
How does the body respond to a higher glucose meal
Increases insulin production
What is the effect of an increased meal size
Increases glycaemic response, glucose levels in the blood are higher and remain in the blood for longer.
Body produces increased insulin
What is the difference in glucaemic responses between cooked (micronised) vs uncooked starch
Raw food causes a lower glycaemic response, however there is therefore less absorption of starch, so more is present in the hindgut and is fermented, changing the ph of the large intestines.
Cooked starch has higher than normal blood glucose levels, (more glucose is absorbed into blood in the small intestine) so not much starch is present in the hindgut. Conserves then environment
What effects glycaemic response
Meal size
Food processing
What is the recommended starch volume
1g/ kg of BW/ meal
What is the function of Parathyroid hormone
increased Ca mobilisation from bone
Increase intestinal absorption of Ca
Increased renal tubular re absorption of Ca
What hormones is the antagonist to Ca
Calcitonin
What can be altered in the diet to increase calcium mobilisation
Acidify diet
Reduce potassium intake
Increase magnesium intake
How does magnesium effect calcium homeostasis
Mg needed for parathyroid hormones secretion and the synthesis of active Vit D
(Low Mg reduces PTH ability to stimulate cells to products cAMP)
How does potassium affect the parathyroid
Induces a change in PTH receptor, so PTH cannot bind
Should you increase of decrease dietary Ca 3 weeks before lactation
DECREASE
To increase Ca mobilisation and increase the efficiency of Ca absorption when you do increase Ca after birth (to maximise Ca absorption)
How can you increase Calcium absorption
Decrease Ca before lactation
Acidify diet
Find balance between Na and Cl
Balance minerals
