| Abstract | Today, consumers meet abundant supply of functional foods with plant stanol increments for serum cholesterol lowering purposes. However, efficacy and safety of plant stanols intake beyond 4 g/day have remained unexplored.We evaluated the effects of very high daily intake of plant stanols (8.8 g/day) as esters on cholesterol metabolism, and serum levels of plant sterols and stanols.In a randomized, double-blind, parallel study of 49 hypercholesterolemic subjects (mean age 62 years, range 41–73) consumed a test diet without (control, n = 24), and with added plant stanol esters (staest, n = 25) over 10 weeks followed by 4 weeks on home diet. Serum lipids, lipoprotein lipids, and non-cholesterol sterols were determined at baseline, during intervention, and 4 weeks afterwards. Cholesterol precursor sterol lathosterol reflected cholesterol synthesis, and serum plant sterols and cholestanol mirrored cholesterol absorption.When compared with controls, 8.8 g/day of plant stanols reduced serum and LDL cholesterol by 12 and 17% (P < 0.01 for both). Synthesis marker lathosterol was increased by 30%, while absorption markers decreased up to 62% when compared with controls (P < 0.001 for both). Serum plant stanols increased slightly, but significantly compared with controls (serum sitostanol during intervention, controls: 16 ± 1 μg/dL, staest: 37 ± 2 μg/dL, serum campestanol during intervention, controls: 0.5 ± 0 μg/dL, staest: 9 ± 1 μg/dL, P < 0.001 for both). Changes in serum cholesterol, non-cholesterol sterols, and plant stanols were normalized during post-treatment weeks.Serum plant stanol levels remained at comparable low levels as in studies with daily intake of 2–3 g, and were normalized in 4 weeks suggesting that daily intake of 8.8 g of plant stanols might not increase systemic availability of plant stanols, but reduces effectively serum cholesterol and plant sterol levels. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
