It is widely recognized that dietary factors play important roles in the development of cardiovascular disease (CVD). We evaluated the association between carbohydrate intake and CVD risk factors, using data from the third Korea National Health and Nutrition Examination Survey (KNHANES III).
A nationally representative sample of Korean adults (1536 men, 2235 women), aged 20 to 69 years, was divided into three groups according to carbohydrate intake (% of energy), based on the Dietary Reference Intakes (DRI, 55-70% of energy) for Koreans. Then, we examined whether excessive carbohydrate intake was related to CVD risk factors.
Mean carbohydrate intake (% of energy) was 72.8% (321 g/day), above the DRI for Korean adults (55-70%). A high carbohydrate intake (>70% of energy) was associated with higher BMI, blood pressure, fasting glucose, triglycerides, and LDL-cholesterol levels in women. After adjusting for covariates, such as age, energy intake, alcohol consumption, smoking status, and physical activity, high carbohydrate intakes (>70% of energy) were significantly associated with diabetes mellitus and low HDL-cholesterol (HDL-C) in women. In men, however, only total cholesterol was inversely associated with high carbohydrate intake.
Higher carbohydrate intakes than the DRI for Koreans were significantly associated with diabetes mellitus and low HDL-C levels in women. These results suggest that improvement of dietary patterns may be an important approach to the prevention of CVD in Korean women.
"In several dietary pattern studies, dyslipidemia had been found to be associated with unhealthy dietary patterns [23,24]. To date, numerous studies have reported associations of dietary patterns with blood lipid profiles and/or blood pressures in various patient populations, including groups with cardiovascular disease, metabolic syndrome, and hypertension in Korea [23,25,26]. "
[Show abstract][Hide abstract] ABSTRACT: The objective of this study is to identify the dietary patterns associated with the risk of hypertensions among Korean adults using data from the Korean National Health and Nutrition Examination Survey (KNHANES, 2008-2010). This study analyzes data from 11,883 subjects who participated in the health and nutrition survey, aging from 20 to 64 years. We performed factor analysis based on the weekly mean intake frequencies of 36 food groups to identify major dietary patterns. We identified three major dietary patterns in both sexes, namely "traditional", "western" and "dairy and carbohydrate" patterns. Participants in the highest quartile of western pattern scores had significantly higher blood pressure, serum total cholesterol, and triglyceride levels than those in the lowest quartile. Although not statistically significant, a trend (P for trend = 0.0732) toward a positive association between the western dietary pattern and hypertension risk was observed after adjustments for age, sex, education, income, body mass index (BMI), smoking, physical activity, and energy intake. The dairy and carbohydrate pattern was inversely related with BMI and blood pressures and positively associated with serum high-density lipoprotein (HDL)-cholesterol. After adjusting the age, sex, education, income, BMI, smoking, physical activity and energy intake, the dairy and carbohydrate pattern showed inverse associations with hypertension prevalence (OR = 0.64, 95% CI = 0.55-0.75; P for trend < 0.0001). Intakes of fiber, sodium, and antioxidant vitamins were significantly higher in the top quartile for the traditional pattern than in the lowest quartile for the traditional pattern (P for trend < 0.0001). Intakes of fiber (P for trend < 0.0001), calcium (P for trend < 0.0001), retinol (P for trend = 0.0164), vitamin B1 (P for trend = 0.001), vitamin B2 (P for trend < 0.0001), niacin (P for trend = 0.0025), and vitamin C (P for trend < 0.0001) were significantly increased across quartiles for the dairy and carbohydrate pattern whereas sodium (P for trend < 0.0001) intake was decreased for this pattern. In conclusion, the dairy and carbohydrate pattern may be associated with a reduced risk of hypertension whereas the western pattern may be associated with an increased risk of hypertension among Korean adults.

"Dietary patterns are also a major contributing factor to the development of CVD
 in association with other risk factors. The dietary fats are the most investigated and fully defined factors
[Show abstract][Hide abstract] ABSTRACT: Background
The high blood lipid levels and obesity are one of the main risk factors for cardiovascular diseases, and the atherosclerotic process begins in childhood. Some environmental factors are supposed to be involved in this relationship, such as dietary factors. This study aimed to investigate the relationship between dietary intake and blood lipids levels in overweight and obese schoolchildren.
This is a cross-sectional study with 147 overweight and obese schoolchildren in Botucatu city, Brazil. The anthropometric measurements (body weight, height, body mass index, waist circumference and skinfolds), pubertal staging evaluation and biochemical tests were taken in all children. Three 24h-recall were applied in order to estimate the dietary intake and its relationship with blood lipid levels. The Student t test and multiple linear regression analysis were used for statistical analysis. Statistical significance was assessed at the level of 0.05. The data were processed in SAS software (version 9.1.3; SAS Institute).
At this study, 63% of children were obese (body mass index higher than 95th percentile) and 80% showed high body fat percentage. The percentage of children with abnormal total cholesterol and triglycerides was 12% and 10%, respectively, and 28% presented at least one abnormal lipid levels. The average values of anthropometric measurements were higher in children with elevated lipid levels. Total cholesterol levels were positively related to full-fat dairy products and triglycerides levels to saturated fat percentage.
Saturated fat was positively associated with elevated lipid levels in overweight and obese schoolchildren. These results reinforce the importance of healthy dietary habits since childhood in order to reduce the risks of cardiovascular diseases in adulthood.

"Among these inconsistent findings, the quantity and quality of carbohydrate intake contributes to metabolic abnormalities, as the Asian diet is typically a high carbohydrate diet, which can raise fasting glucose and triglycerides but reduce HDL-cholesterol. Among several studies on dietary carbohydrates, the glycemic index (GI) was reportedly associated with metabolic risk factors in Asian populations [13-15], but no study has been conducted on dietary patterns based on carbohydrate nutrition. "
[Show abstract][Hide abstract] ABSTRACT: Several studies have been conducted on dietary patterns based on carbohydrate nutrition in Asian populations. We examined the cross-sectional associations in dietary patterns based on carbohydrate nutrition, including the glycemic index (GI) with dyslipidemia and diabetes among the Korean adult population. We analyzed 9,725 subjects (3,795 men and 5,930 women, ≥ 20 years) from the Fourth Korea National Health and Nutrition Examination Survey. Dietary information was collected using single 24-hour recall. Reduced rank regression was used to derive dietary patterns from 22 food groups as predictor variables and four dietary factors related to the quantity and quality of carbohydrates as response variables. Two dietary patterns were identified: 1) the balanced pattern was characterized by high intake of various kinds of foods including white rice, and 2) the rice-oriented pattern was characterized by a high intake of white rice but low intake of vegetables, fruits, meat, and dairy products. Both patterns had considerable amounts of total carbohydrate, but GI values differed. The rice-oriented pattern was positively associated with hypertriglyceridemia in men and low high density lipoprotein-cholesterol in both men and women. The balanced pattern had no overall significant association with the prevalence of dyslipidemia or diabetes, however, men with energy intake above the median showed a reduced prevalence of diabetes across quintiles of balanced pattern scores. The results show that dietary patterns based on carbohydrate nutrition are associated with prevalence of dyslipidemia and diabetes in the Korean adult population.
