Laboratory tests -cholesterol- up with saturated fatty acids (sfa),trans - down with polyunsaturated fatty acids (pufa) -triglycerides-down with oleic acid, up with saturated fats and obesity -HDLc-up with pufa down with sfa,trans -LDLc-up with saturated fatty acids (sfa), trans down with polyunsaturated fatty acids (pufa) -blood glucose-up with obesity-relationship to above
