Tomato juice: Can 1 cup per day stop heart disease?


Researchers recently investigated the potential benefits of tomato juice for cardiovascular risk. Although the team reported lowering blood pressure and cholesterol levels, the results were not entirely convincing.
Cardiovascular disease is the cause of most deaths in the United States.

People can change some risk factors such as smoking, but it is impossible to change others such as age.

As the population ages, it is increasingly important to find ways to reduce cardiovascular risk.

Diet is very important for good health, and heart health is no exception. A new study asks whether regular consumption of salt-free tomato juice can be a cost-effective measure.

The study authors explained how tomatoes contain various bioactive substances, such as carotenoids, vitamin A, calcium and gamma-aminobutyric acid, which can play a role in maintaining physical and mental health, including prevention [cardiovascular disease]. . “

Short atherosclerosis

The main driver of cardiovascular disease is atherosclerosis, which occurs when plaque builds up in blood vessels. Over time, the plaque becomes stiff and narrows the arteries.

Atherosclerosis begins when the endothelium or the surface of the blood vessels is damaged.

This damage can occur for a number of reasons, including high blood pressure, diabetes and blood cholesterol. Controlling these three factors can significantly reduce the risk of arteriosclerosis and other cardiovascular diseases.

The authors of the study published the latest survey in 2015. In a previous study, they concluded that for 8 weeks reduced the amount of triglycerides in the blood of middle-aged women drinking fresh tomato juice. Triglycerides are a type of fat; Most of this fat contributes to arteriosclerosis.

Look again at tomato juice

Previous findings encourage researchers to expand their tissue and to determine whether tomato juice can also take advantage of other cardiovascular risk factors such as high blood pressure and lipid and glucose metabolism for a longer period of time.

This time, they also want to measure the benefits of tomato juice in people of various ages and genders. Scientists publish the results in Food Science & Nutrition.

According to the authors, “this study is the first to investigate the effect of ingesting tomato or tomato products on a one-year cardiovascular risk marker, and at a wide age range.”

At this stage, it is important to know that the author of Kikkoman Corporation has received a grant to conduct a previous study.

Kikkoman Corporation produces a variety of soy sauce, but also has exclusive rights to the Del Monte brand in Asia, where the company “produces and sells tomato-based products.”

1 cup per day

In total, 184 men and 297 women took part. For one year, all participants had access to the fresh tomato juice they wanted. The average is 215 milliliters per day per person, which is slightly less than 1 cup.

At the beginning and end of the study, the researchers measured a number of factors, including blood pressure, triglyceride and cholesterol levels, and fasting plasma glucose.

They analyzed data from 94 participants with hypertension or hypertension (high blood pressure was not high enough to get a diagnosis of hypertension).

Your blood pressure is significantly lower after one year of consuming tomato juice. The average systolic blood pressure drops from 141.2 to 137.0 mmHg (mmHg). The average diastolic blood pressure also dropped from 83.3 to 80.9 mm Hg.

According to the American Heart Association (AHA) guidelines, this change in blood pressure will shift the average participant from high blood pressure to level 2 to high blood pressure level 1.

This effect is similar for men and women as well as for people of all ages.

There are no changes for glucose or triglycerides

The researchers also evaluated glucose metabolism in 62 subjects with untreated glucose tolerance; However, there was no significant improvement for these people.

In a subset of 127 subjects with abnormal blood lipid levels, there were no changes in HDL or “good” cholesterol.

However, they see a significant decrease in levels of low density lipoprotein (LDL) or “bad” cholesterol. LDL is a risk factor for atherosclerosis.

It is important that the researchers use a questionnaire to ensure that participants’ lifestyles do not change significantly throughout the year, which can explain these beneficial changes.
