[The future of nutrition and medicine – analysis of genetic expression] Energy Restriction Lowers the Expression of Genes Linked to Inflammation, the Cytoskeleton, the Extracellular Matrix, and Angiogenesis in Mouse Adipose Tissue, Yoshikazu Higami et al

Using high-density oligonucleotide microarrays, we examined the actions of energy restriction (ER) on the expression of >11,000 genes… Four groups were studied: controls not subjected to food restriction (CO), food-restricted 18 h before being killed (FR), short-term ER for 23 d (SER), and long-term ER for 9 mo (LER). ..however, 345 transcripts of 6266 genes determined to be expressed in WAT were significantly altered by LER. We focus here on the 109 (31%) of these genes…Our findings provide evidence that LER suppresses the expression of genes encoding inflammatory molecules in WAT while promoting structural remodeling of the cytoskeleton, extracellular matrix, and vasculature. These alterations may play an important role in the protection against WAT-derived inflammation and in lifespan extension by LER.

[Synthetic CLAs may be hazardous] Trans-10, cis-12- and cis-9, trans-11-Conjugated Linoleic Acid Isomers Selectively Modify HDL-Apolipoprotein Composition in Apolipoprotein E Knockout Mice, José M. Arbonés-Mainar et al

These results indicate that trans-10, cis-12-CLA intake [found in some supplements] modifies HDL to form a proatherogenic apoA-II containing particle and promotes phenotypic changes compatible with metabolic syndrome. Cis-9, trans-11-CLA [found in natural dairy products] does not promote this detrimental effect.

[Not eating starch and sugar improves your health] Carbohydrate Restriction Alters Lipoprotein Metabolism by Modifying VLDL, LDL, and HDL Subfraction Distribution and Size in Overweight Men, Richard J. Wood et al

We conclude that weight loss induced by Carbohydrate Restriction favorably alters the secretion and processing of plasma lipoproteins, rendering VLDL, LDL, and HDL particles associated with decreased risk for atherosclerosis and coronary heart disease.
