Matched for available carbohydrate content of baked potato

Healthy

Toasted, with canola oil added to match for fat content of French fries (13.9 grams), as well as being matched for energy (280 kilocalories) and available carbohydrate content (33 grams) of potato treatments.

White bread

Baked russet potato with canola oil added once baked to match for fat content of French fries, and also matched for the salt content of white bread (280 milligrams).

Baked potato with skin

Mashed potatoes prepared from frozen, with canola oil added to match for fat content of French fries, as well as being matched for energy and available carbohydrate content of the baked potato.

Effect of White Potatoes on Glycemic Response and Satiety in Older Adults

Food intake will be determined by weighing the meal before and after serving. The net weight of the test meal will be converted to calories

Blood glucose (mmol/L). Blood glucose will be measured in whole blood using YSI 2300 STAT PLUS (YSI Incorporated, Yellow Springs, OH)

Blood insulin (pmol/L). Insulin concentration in serum will be determined in duplicate via enzyme-linked immunosorbent assay kits (ELISA; Millipore, Billerica, Massachusetts).

Measured using visual analogue scale (mm). Each VAS is a 100 mm line where they will place a pencil mark to describe their feelings.

Blood CCK (pmol/L). CCK concentration in serum will be determined in duplicate via enzyme-linked immunosorbent assay kits (ELISA; Millipore, Billerica, Massachusetts)

Blood DPP4 (ng/mL). DPP4 concentration in serum will be determined in duplicate via enzyme-linked immunosorbent assay kits (ELISA; Millipore, Billerica, Massachusetts)

Blood GIP (pmol/L). GIP concentration in serum will be determined in duplicate via enzyme-linked immunosorbent assay kits (ELISA; Millipore, Billerica, Massachusetts)

Blood GLP-1 (pmol/L). GLP-1 concentration in serum will be determined in duplicate via enzyme-linked immunosorbent assay kits (ELISA; Millipore, Billerica, Massachusetts)
