Concentrates from tender coconut water and coconut testa beneficially modulates tissue lipid profiles in high-fat fed rats.

The present study involved feeding of tender coconut water concentrate (TCW) and testa phenolic concentrate (PHE) to high fat fed animals. Analysis of serum showed increased HDL-C in concentrates treated group and therefore higher protection against atherogenesis compared to high fat fed group. Lesser fecal fat content and higher level of liver cholesterol were observed in high fat fed group, treatments with TCW and PHE ameliorated significantly. Fat content in the organs (liver, heart, kidney and adipose) of HFD group was high. Furthermore, certain fatty acids observed in the tissues were 14:0, 16:0, 18:0, 18:1, 18:2, 20:0, 20:3 and 20:4, among which 14:0, 16:0 & 18:0 are the major saturated fatty acids that increased significantly in high fat fed group when compared with starch fed group and ameliorated with TCW and PHE dose dependently. These results clearly indicate both the concentrates (TCW and PHE) restrict excess accumulation of lipids and altered composition of fatty acids in tissues as well as serum which are the risk factors for development of insulin resistance, hyperlipidemia, dyslipidemia etc., related to obesity.
