Results of the analysis indicated that increased consumption of unsaturated fats , fruits , vegetables and low-fat dietary products  , decreased consumption of dietary sodium and beverages containing caffeine , and breastfeeding were found to have preventive effects against high blood pressure in later years of life .
The effects of training given during youth to encourage a healthy lifestyle and behavior changes based on diet and physical activity were also noted
The aim of this systematic review was to analyze the results of observational and interventional research / studies on nutrition-based practice s in the prevention of hypertension among healthy youth .
The effect of low-fat versus whole-fat dairy product intake on blood pressure and weight in young normotensive adults.
BACKGROUND Epidemiologic and experimental studies suggest that higher intake of dairy products could be associated with lower risk of hypertension and obesity . Differences in nutrient composition of distinct dairy products suggest that their effect on these outcomes might be heterogeneous . However , little experimental research has examined the potentially different effects of low- and whole-fat dairy products on blood pressure ( BP ) and weight change . The present study aim ed to assess whether supplementing diets with low- or whole-fat dairy products would differentially affect BP levels and weight . METHODS A r and omised crossover trial in 45 normotensive volunteers ( 18 - 24 years old , 49 % female ) was conducted . Participants alternatively received 3.5 servings/day of whole-fat or low-fat dairy products ( milk and yogurt ) in addition to their usual diet during two 8-week periods , with a 4-week washout period between both interventions . Weight and BP were measured at the beginning and end of each intervention . RESULTS Whole-fat dairy supplementation significantly increased systolic BP [ 2.1 mmHg , 95 % confidence interval ( CI ) = 0.1 - 4.0 , P = 0.04 ] and weight ( 1.0 kg , 95 % CI = 0.5 - 1.5 , P = 0.0002 ) , but not diastolic BP ( P = 0.34 ) . Weight and BP did not change significantly after the low-fat dairy intervention ( P > 0.10 ) . There were no significant differences in the effect of low-fat or whole-fat dairy products on BP ( P > 0.60 ) , but whole-fat dairy increased weight significantly compared to low-fat dairy ( 1.2 kg , 95 % CI = 0.5 - 1.8 , P = 0.0007 ) . CONCLUSIONS In a young nonhypertensive population , dietary supplementation with whole-fat dairy products , compared to low-fat dairy , was associated with weight gain . No differential effects were observed for levels of BP
