Omega-3 and Heart Health
- Omega-3, a type of fat, is often touted as essential for heart health, leading to a booming fish oil supplement industry.
- However, its effectiveness has been questioned recently, sparking debate among scientists.
Types of Omega-3
- There are three main types of omega-3 fatty acids: ALA (found in plants), EPA, and DHA (found in oily fish).
- EPA and DHA are crucial for cell membranes, brain function, and vision, while ALA can be converted to EPA and DHA, but only in small amounts.
Conflicting Evidence
- Studies on omega-3's effectiveness show conflicting results, some showing significant benefits while others show little to no effect.
- This division stems from differences in study design, such as the use of statins by participants and dosage of omega-3.
