Conclusions Large r and omized controlled trials of at least 6 months duration with carbohydrate restriction appear superior in improving lipid markers when compared with low-fat diets .
Context Carbohydrate-restricted diets may increase low-density lipoprotein cholesterol and thereby cardiovascular risk .
Objective A systematic review and meta-analyses were conducted to compare the effects of very low , low , and moderate carbohydrate , higher fat diets versus high-carbohydrate , low-fat diets on low-density lipoprotein cholesterol and other lipid markers in overweight/obese adults .
Beyond low-density lipoprotein cholesterol: respective contributions of non-high-density lipoprotein cholesterol levels, triglycerides, and the total cholesterol/high-density lipoprotein cholesterol ratio to coronary heart disease risk in apparently healthy men and women.
OBJECTIVES This study was design ed to test the hypothesis that at any low-density lipoprotein cholesterol ( LDL-C ) level , other lipid parameters such as non-high-density lipoprotein cholesterol ( HDL-C ) levels , triglyceride ( TG ) levels , and the total cholesterol (TC)/HDL-C are still associated with an increased coronary heart disease ( CHD ) risk . BACKGROUND Although LDL-C is considered to be the primary target of lipid-lowering therapy , other parameters of the lipoprotein-lipid profile may more closely associated with CHD risk . METHODS In the EPIC ( European Prospect i ve Investigation Into Cancer and Nutrition)-Norfolk prospect i ve population study , 21,448 participants without diabetes or CHD between age 45 and 79 years were followed for 11.0 years . A total of 2,086 participants developed CHD during follow-up . RESULTS Among individuals with low LDL-C levels ( < 100 mg/dl ) , after adjustment for age , sex , smoking , systolic blood pressure , waist circumference , physical activity , and hormone replacement therapy ( in women ) , those with non-HDL-C > 130 mg/dl had a hazard ratio ( HR ) for future CHD of 1.84 ( 95 % confidence interval [ CI ] : 1.12 to 3.04 ) when compared with those with non-HDL-C levels < 130 mg/dl . In a similar model , individuals with TG levels > 150 mg/dl had an HR of 1.63 ( 95 % CI : 1.02 to 2.59 ) when compared with those with TG levels < 150 mg/dl , and individuals with a TC/HDL-C ratio > 5 had an HR of 2.19 ( 95 % CI : 1.22 to 3.93 ) when compared with those with a TC/HDL-C ratio < 5 . CONCLUSIONS In this prospect i ve study , independently of their plasma LDL-C levels , participants with high non-HDL-C levels , high TG levels , or with an elevated TC/HDL-C ratio were at increased CHD risk . CHD risk assessment algorithms as well as lipid targets of lipid-lowering trials may also need to consider other easily available parameters such as
