Tomato juice and heart health

Cardiovascular issues have been the major cause of death in American population. There are many reasons leading to heart related issues which are controllable as well as uncontrollable. Factors like smoking habit, obesity etc. are controllable while the ones like ageing are uncontrollable. From previous studies, scientists have proved that tomatoes, which are abundant in bioactive compounds, such as carotenoid, vitamin A, calcium, and gamma‐aminobutyric acid, help in benefitting cardiovascular risk elements such as high blood pressure and lipid and glucose metabolism, over a longer period. Having 1 glass of unsalted tomato juice included in daily diet is said to have remarkable benefits on cardiovascular health. "The current study is the first to investigate the effects of tomato or tomato product intake on cardiovascular disease risk markers over the course of a year and over a wide age range.", report the authors. Men and women participants were included in the study, whose health factors like blood pressure, levels of triglycerides and cholesterol in the blood, and fasting plasma glucose were measured. They were provided with unlimited access to unsalted tomato juice for one year. Results reflected that their average systolic blood pressure dropped from 141.2 to 137.0 millimeters of mercury (mm Hg). Also, average diastolic blood pressure dropped from 83.3 to 80.9 mm Hg. Another positive aspect found was that they benefitted in reducing hypertension stage 2 down to hypertension stage 1 in participants.

Are white meats actually better than red meats?

The upper hand of white meat like chicken over red meat like pork, lamb and beef in health aspect has been a widely believed fact. Scientists looked into the comparison and came out with a quite disappointing news to white meat eaters. Red meat intake was always related to higher cardiovascular risk and white meat was always considered the safe option of meat consumption. The study was conducted to know more about how intake of various meats affect the levels of lipids and lipoproteins that can cause fatty deposits to form on the arteries. During the study, participants were divided into three groups consuming red meat, white meat and plant-based proteins respectively. Results showed that the groups who consumed red and white meat had the same increasing effect on their blood cholesterol levels while the ones who consumed plant-based protein experienced lowering of cholesterol. When we planned this study, we expected red meat to have a more adverse effect on blood cholesterol levels than white meat, but we were surprised that this was not the case — their effects on cholesterol are identical when saturated fat levels are equivalent.", says Dr. Ronald Krauss, senior scientist and director of Atherosclerosis Research at the Children's Hospital Oakland Research Institute in California. It is evident from the result to add more plant-based products in daily diet and that choosing white meat over red meat does not cause any difference as both of their LDL concentrations are higher than those resulting from vegetable protein sources.
