According to a study published in the Clinical Journal of the American Society of Nephrology , an orange juice a day prevents the formation of kidney stones thanks to its citrate content. In addition, citrus fruits such as orange and grapefruit contain flavonoid substances, specifically hesperidin, which reduce the risk of heart attack by up to 19% , according to research carried out at the University of East Anglia (United Kingdom). These same substances can also lower blood pressure and prevent cardiovascular problems. In addition, another study published in the journal Nutrition Research suggests that concentrated natural orange juice reduces levels of "bad" cholesterol (LDL).
Added to this is a study by the Florida Orange Juice company, in collaboration with researcher Sonja Lyubomirsky, from the University of California, which suggests that drinking orange juice at the beginning of the morning makes us feel in a better mood and full of energy during the day.
