Claims that tomato juice is good for the heart not backed by evidence

With the weak study design and the small sample of Japanese people with blood pressure or cholesterol problems who may not be representative, this overall represents rather poor evidence that tomato juice is good for the heart. This study simply offered free tomato juice to people and measured their blood pressure and cholesterol before and after. The researchers said: “Our study shows that unsalted tomato juice intake could have improved systolic and diastolic blood pressure in Japanese residents who had untreated [borderline hypertension] or hypertension, and also decreased the serum LDL-C level in those who had untreated [raised cholesterol].”
