Spinacia oleracea in diet can help control obesity by its regulatory action on appetite
Vandana Sanjeev Panda
Mumbai University, India
Nutrients and gastrointestinal peptide hormones such as cholecystokinin (CCK), GLP-1 and peptide YY are involved in
the short term regulation of food intake, which interact with long term regulators such as insulin, leptin and ghrelin to
maintain energy homeostasis. Plant foods have been proven to be effective in modifying release of these short term satiety
signals which regulate the balance between food intake and energy expenditure to maintain body weight. Spinacia oleracea
(spinach) is a green leafy vegetable rich in antioxidant phyto-constituents such as flavonoids, polyphenols, carotenoids and
vitamins. The present study evaluates the appetite suppressing effect of a flavonoid rich extract of the spinach leaf (SOE) in
rats. Rats were administered SOE (200 mg/kg and 400 mg/kg, p.o) and fluoxetine (6 mg/kg i.p) as a pre-meal for 14 days. Food
intake and weight gain was observed daily during the treatment period. Serum levels of the short term satiety signals CCK and
glucose were measured on the 7th and 14th days at different time points after start of meal to study the satiety inducing effect
of SOE. SOE and fluoxetine treated rats showed a significant reduction in food intake and weight gain when compared with
the normal control rats. On the 7th day of treatment, peak CCK levels were reached in 30 min after start of meal in fluoxetine
treated rats and in 60 min in the remaining rats. On the 14th day, CCK peaking was observed in 30 min after starting meal in
the fluoxetine as well as SOE 400 mg/kg treated rats. Peak glucose levels in all treatment groups were obtained in 60 min after
start of feeding on both days of the study. It may be concluded that SOE exhibited a promising appetite suppressing effect by
inducing a quicker than normal release of CCK, thus eliciting an early onset of satiety in rats.

Biography
Vandana Sanjeev Panda has completed her PhD in Pharmacology from Mumbai University, India. Her research for the last few years has changed focus from
pure pharmacology to plant drugs and now functional foods where her lab is active in pharmacological evaluation of plant phyto-constituents, bio-molecules and
endogenous substances for a variety of biological activities, their mechanistic studies and development of models for these activities. Her major work has been in
the area of gastric and hepato-protection, anti-diabetic and cardio-protective activity, and studies on the metabolic syndrome. She has 40+ research papers with
850 citations in high impact factor journals, a number of research awards and scholarships, and industrial projects to her credit. She sits on the Editorial Board of
a few journals and is a Reviewer for many reputed journals.
