1. Cardiovascular Disease & Cardiac Remodeling:
• Cardiovascular disease (CVD) can be influenced by diet and other behavioral factors.
• Cardiac remodeling, a key process in many CVDs, involves cellular and molecular changes that lead to structural and functional heart alterations.
• These changes include myocyte hypertrophy, interstitial fibrosis, increased oxidative stress, inflammation, apoptosis, and altered energy metabolism.
2. Orange Juice as a Cardioprotective Food:
• Researchers from São Paulo State University, Brazil, highlighted orange juice as an accessible dietary option with potential heart health benefits.
• Studies suggest that consuming orange juice may help counteract cardiac remodeling and improve cardiovascular health.
3. Metabolomic Studies on Orange Juice:
• A study found that drinking orange juice for two weeks can modify blood levels of acyl-carnitines, which are involved in liver fatty acid metabolism.
• Another study indicated that overweight and obese adults who drink orange juice experience reduced oxidative stress, anti-inflammatory effects, and changes in gut microbiota metabolism.
4. Key Bioactive Components in Orange Juice:
• Orange juice increases phosphatidylethanolamine (PE) and cyclic phosphatidic acid (CPA):
• PE enhances energy metabolism, mitochondrial function, and reduces oxidative stress and inflammation.
• CPA helps prevent arterial wall remodeling and inflammation, potentially reducing the risk of atherosclerosis.
5. Additional Potential Benefits:
• Orange juice may influence endocannabinoids, which could help regulate cardiac function.
• It might also support gut microbiota balance, potentially lowering risks of obesity and insulin resistance.
6. Study Limitations & Future Research:
• Further studies are needed to confirm the metabolic effects of orange juice in CVDs.
• The research was funded by Brazil’s National Council for Scientific and Technological Development, a country known for its strong orange juice industry. However, no conflicts of interest were reported by the authors.
