False. Prebiotic fructans do not determine insulin-induced laminitis risk in metabolic equines. Simple sugars (glucose, sucrose, fructose) and starch are the carbohydrates in grass and hay that stimulate glucose and insulin production. Fructans serve as prebiotic fiber and are fermented by bacteria, primarily in the gut, and do not produce a significant glucose/insulin response (Kalck, Frank et al. 2009, Geor, DeSilva et al. 2010) Pasture analysis by Kagan, Lawrence et al (2017) found that the majority of carbohydrate was simple sugar, leading the authors to conclude, “…more consideration should be given to mono- and disaccharides, particularly sucrose, than to fructan when managing grazing horses at risk for (insulin-induced) laminitis.”
%NSC = The sum of percent fructans, simple sugars, and starch
%WSC = The sum of percent fructans and simple sugars
%ESC = Simple sugars (glucose, sucrose, fructose)
%Starch = starch
%ESC + starch = The sum of insulin-stimulating carbohydrates (insulin is the direct cause of insulin-induced laminitis) Insulin-induced laminitis is the #1 cause of most laminitis cases.
Keeping the sum of percent ESC and starch below 10% will significantly reduce laminitis risk in equines with abnormally elevated insulin. To learn more facts about managing metabolic horses, ponies, donkeys, and mules, visit https://bit.ly/3fZPbKm
