Two-month orange juice consumption linked to changes in thousands of genes
A study published in the journal "Molecular Nutrition & Food Research" found that daily consumption of 500 ml of pure pasteurized orange juice over two months affects gene activity in immune cells. After 60 days, researchers observed a decrease in the activity of genes associated with inflammation and blood pressure.
A study published in the scientific journal "Molecular Nutrition & Food Research" found that daily consumption of 500 ml of pure pasteurized orange juice over two months affects gene activity in immune cells.

These findings help clarify the link between orange juice consumption and heart health markers.
While many view a glass of orange juice as a standard breakfast staple, recent research suggests that natural compounds in oranges can influence various physiological processes, including metabolism, blood vessel function, and inflammation.
In this study, participants consumed 500 ml of pure pasteurized orange juice daily for two months. Researchers analyzed immune system cells and discovered changes in the activity of thousands of genes. It is important to note that this does not alter the DNA itself, but rather changes the degree to which the body utilizes specific genetic instructions.
After 60 days, the researchers observed reduced activity in genes related to inflammatory processes and blood pressure, specifically NAMPT, IL6, IL1B, and NLRP3. A decrease was also recorded in the SGK1 gene, which regulates how the kidneys process sodium. These findings offer a potential explanation for previous studies linking regular orange juice consumption to improved cardiovascular health.
One of the substances likely responsible for this effect is hesperidin, a natural antioxidant found in citrus fruits. Interestingly, the response varied among participants: those with higher body weight showed more significant changes in genes related to fat processing, while thinner participants exhibited stronger effects on inflammation-related processes.
These findings align with a review of 15 controlled studies involving 639 participants, which linked regular orange juice consumption to reduced insulin resistance and cholesterol levels. Other studies have noted slight decreases in blood pressure and increases in HDL, or "good cholesterol." Furthermore, research on gut health suggests that blood orange juice may boost beneficial bacteria that help regulate inflammation.
It is important to qualify these results: the study does not prove that orange juice prevents heart attacks, and changes in gene activity do not necessarily translate into significant health improvements. Additionally, orange juice contains natural sugar and lacks the fiber found in whole fruit; therefore, these findings do not constitute a medical recommendation to consume large quantities of juice.
