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 .
Blood Pressure Is Lower in Children and Adolescents With a Low-Saturated-Fat Diet Since Infancy: The Special Turku Coronary Risk Factor Intervention Project
Blood pressure was measured in the prospect i ve r and omized Special Turku Coronary Risk Factor Intervention Project Study with an oscillometric method every year from 7 months to 15 years of age in 540 children receiving a low-saturated-fat , low-cholesterol diet and in 522 control children . Dietary intakes , family history of parental hypertension , and gr and parental vascular disease were recorded . Systolic and diastolic blood pressures were 1.0 mm Hg lower ( 95 % CI for systolic : −1.7 to −0.2 mm Hg ; 95 % CI for diastolic : −1.5 to −0.4 mm Hg ) in children receiving low-saturated-fat counseling through childhood than in control children . Intakes of saturated fat  were lower ( P<0.001 ) , those of  polyunsaturated fat  higher ( P<0.001 ) , and intakes of potassium  slightly higher ( P=0.002 ) in the intervention group , but sodium intakes were not influenced by the intervention ( P=0.76 ) . Children whose parents were hypertensive had 4- to 6-mm Hg higher systolic and 3- to 4-mm Hg higher diastolic blood pressures than children of normotensive parents ( P<0.001 ) . Diastolic blood pressure of children with gr and  parental vascular disease , ie , early cardiovascular or cerebrovascular disease , tended to be higher than that of children with no gr and parental disease ( P=0.051 ) . We conclude that restriction of saturated fat from infancy until 15 years of age decreases childhood and adolescent blood pressure with a meaningful population -attributable amount . The importance of childhood lifestyle counseling and primary prevention of hypertension should be emphasized , especially in those children with a family history of hypertension or atherosclerotic vascular disease
