very interesting. I will search Jefferson on google.
And I really appreciate you giving me an excellent excuse to eat a bit
of ice cream every afternoon! ;-))
Hi Jolanna and with an emphasis on the word _bit_ ....,
it all depends where you are.If you still have the second phase insulin
response and how fast and how much .... For me I can "prime" it with 1
slice (35 g) of bread during a 30 min walk.After another 30 min I can have a
fairly carby breakfast if I want.
The incretin effect depends if you have enough l-cells , which depends on
the amount of fiber that was in your diet for the last months or so.The
l-cells produce lots og GLP-1 if you "prime" them with fat.Some fats work
better than others.For me I indeed took an ice cream and eat it while
walking to the restaurant where we had sushi ( rice !! but also fish) to
celebrate my friends birthday.Even the rice did not spike me.I hope it works
for you too.
Take the calories in account though :(
Nice word : "prime"
Here is an article (free) :
J Clin Endocrinol Metab. 2006 Jun;91(6):2062-7.
Effects of fat on gastric emptying of and the glycemic, insulin, and
incretin responses to a carbohydrate meal in type 2 diabetes.
CONTEXT: Gastric emptying (GE) is a major determinant of postprandial
glycemia. Because the presence of fat in the small intestine inhibits GE,
ingestion of fat may attenuate the glycemic response to carbohydrate.
OBJECTIVE: The objective of this study was to evaluate the effect of
patterns of fat consumption on GE and glucose, insulin, glucagon-like
peptide-1 (GLP-1), and glucose-dependent insulinotropic polypeptide (GIP)
concentrations after a carbohydrate meal in type 2 diabetes. DESIGN: This
was a randomized, cross-over study in which GE of a radioisotopically
labeled potato meal was measured on 3 d. SETTING: The study was performed at
the Royal Adelaide Hospital. PATIENTS: Six males with type 2 diabetes were
studied. INTERVENTION: Subjects ingested 1) 30 ml water 30 min before the
mashed potato (water), 2) 30 ml olive oil 30 min before the mashed potato
(oil), or 3) 30 ml water 30 min before the mashed potato meal that contained
30 ml olive oil (water and oil). MAIN OUTCOME MEASURES: GE, blood glucose,
plasma insulin, GLP-1, and GIP concentrations were the main outcome
measures. RESULTS: GE was much slower with oil compared with both water (P <
0.0001) and water and oil (P < 0.05) and was slower after water and oil
compared with water (P < 0.01). The postprandial rise in blood glucose was
markedly delayed (P = 0.03), and peak glucose occurred later (P = 0.04) with
oil compared with the two other meals. The rises in insulin and GIP were
attenuated (P < 0.0001), whereas the GLP-1 response was greater (P =
0.0001), after oil. CONCLUSIONS: Ingestion of fat before a carbohydrate meal
markedly slows GE and attenuates the postprandial rises in glucose, insulin,
and GIP, but stimulates GLP-1, in type 2 diabetes.
