A recent Swedish study shows that drinking spinach juice – instead of cooking it – is the best way to take advantage of its antioxidants, which fight atherosclerosis.
The study was conducted by researchers from the Swedish University of Linchoping and published their findings in the latest issue of the Journal of Food Science Chemistry.
Spinach contains high levels of natural antioxidant lutein, natural pigments that make spinach dark green.
The team investigated the role of lutein, an antioxidant, and found that it can stop immune cell inflammation in patients with coronary artery disease.
According to the study, many people with atherosclerosis suffer from chronic inflammation that can be measured in the blood and are associated with increased inflammation of the risk of myocardial infarction.
To achieve the results of the new study, researchers investigated different ways to consume different spinach to get the most lutein possible.
The researchers showed spinach, frying and boiling spinach for an hour and a half, measured the lutein content at different times in the preparation and compared it to raw spinach, presented as juice.
Researchers have found that the best way to consume spinach for high levels of lutein is to drink juice rather than boiling, fried or even steamed.
Heating time
The researchers also found that the heating time was very important during the preparation. The longer the spinach period, the lower the lutein levels. When the spinach is fried at high temperature, a large part of the lute decomposes after only two minutes.
The results also revealed that heating the grill in the microwave oven loses many levels of lutein because the plant structure is strongly disintegrated by the microwave oven and it is best not to warm it up.
"It's best not to heat the spinach at all," said Dr. Lina Yunasson, lead author. "It's best to eat them as fruit juice and add fat, like dairy products like cream, milk and milk."
According to the World Health Organization, about 17.3 million people die each year from heart disease, accounting for 30% of the total number of deaths worldwide each year. By 2030, 23 million deaths from heart disease are expected each year.
