Tomato Juice May Improve Blood Pressure and Cholesterol
Tomatoes are rich in vitamin C, vitamin B, potassium, and antioxidants such as lycopene. According to a new study, unsalted tomato juice may help improve blood pressure and cholesterol levels.
Participants in the study included 481 adults with an average age of 57. They were given as much unsalted tomato juice as they wanted for one year, and they kept daily records of their consumption. The researchers assessed blood pressure, serum lipids, and glucose tolerance at baseline and at the end of the study.
Throughout the study period, the average daily tomato juice consumption was 7.2 ounces. The researchers compared baseline and end of study blood pressure levels in 94 participants who had untreated prehypertension or hypertension at the beginning of the study. They found that systolic blood pressure lowered from an average of 141.2 to 137.0 mmHG. Diastolic blood pressure lowered from an average of 83.3 to 80.9 mmHG.
At the beginning of the study, 125 participants had high cholesterol. Their levels went from an average of 155.0 at baseline to 149.9 mg/dl at the end of the study.
The study was conducted by researchers Tokyo Medical and Dental University. It was published online ahead of print on May 15, 2019 in the journalFood Science & Nutrition.
