Vitamin C Helps to Regulate Blood Pressure

High blood pressure (hypertension) is a leading cause of cardiovascular disease, with more than 1 billion people worldwide suffering from the condition.   Stephen P Juraschek, from Johns Hopkins School of Medicine (Maryland, USA), and colleagues completed a meta-analysis of 29 clinical trials, in which the median dose of vitamin C supplementation was 500 mg per day for a median duration of eight weeks. Across study subjects, the researchers found that vitamin C supplementation reduced systolic blood pressure by 3.84 mm Hg and diastolic blood pressure by 1.48 mm Hg. Further, when the team looked at hypertensive patients only, vitamin C supplementation exerted and even greater benefit – reducing systolic pressure by 4.85 mm Hg and diastolic pressure by 1.67 mm Hg. cap the study authors conclude that: "In short-term trials, vitamin C supplementation reduced [systolic blood pressure] and [diastolic blood pressure].

255. The Negatives of Additives
Phosphate, in the inorganic form, is commonly present in many types of fast food. Its consumption can measurably elevate the serum phosphate concentration, which may pose a health risk among patients with compromised kidney function. German researchers report that because inorganic phosphate is entirely resorbed in the gastrointestinal tract, people with renal disease are at increased risk of death...
