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 .
Caffeine Affects Cardiovascular and Neuroendocrine Activation at Work and Home
Objective This study investigated the effects of moderate doses of caffeine on ambulatory blood pressure and heart rate , urinary excretion of epinephrine , norepinephrine , and cortisol , and subjective measures of stress during normal activities at work and at home in the evening . Methods Healthy , nonsmoking , habitual coffee drinkers ( N = 47 ) participated in 3 days of ambulatory study . After a day of ad lib caffeine consumption , caffeine ( 500 mg ) and placebo were administered double-blind in counter-balanced order on separate workdays . Ambulatory blood pressure and heart rate were monitored from the start of the workday until bedtime . Urinary excretion of catecholamines and cortisol was assessed during the workday and evening . Results Caffeine administration significantly raised average ambulatory blood pressure during the workday and evening by 4/3 mm Hg and reduced average heart rate by 2 bpm . Caffeine also increased by 32 % the levels of free epinephrine excreted during the workday and the evening . In addition , caffeine amplified the increases in blood pressure and heart rate associated with higher levels of self-reported stress during the activities of the day . Effects were undiminished through the evening until bedtime . Conclusions Caffeine has significant hemodynamic and humoral effects in habitual coffee drinkers that persist for many hours during the activities of everyday life . Furthermore , caffeine may exaggerate sympathetic adrenal-medullary responses to the stressful events of normal daily life . Repeated daily blood pressure elevations and increases in stress reactivity caused by caffeine consumption could contribute to an increased risk of coronary heart disease in the adult population
