Vitamin K, which is found in kale, spinach and broccoli, maintains the size of the vital organ's left ventricle, a study found, which is responsible for pumping oxygen-rich blood around the body.
Insufficient levels of the vitamin cause the left ventricle to enlarge, the research adds. Previous research reveals large hearts do not pump blood as efficiently as they should, which can result in fatal heart attacks. The more vitamin K a person has, the less likely they are to develop an enlarged heart, the study found. Past research suggests vitamin K may activate a protein involved in maintaining heart size.
Researchers from Augusta University analyzed 766 healthy teenagers aged between 14 and 18. The study's participant's diet and activity levels were measured over seven days via self-reporting and devices that assess acceleration. Their heart's structure and function was investigated via ultrasound scans.------
The findings were published in The Journal of Nutrition.
