Are Omega-6 Fatty Acids Good for You?
Omega-6 fatty acids are good in moderate amounts since they help brain function, but too much can promote inflammation.
Omega-6 fatty acids can be both good and bad for health depending on the balance with omega-3 fatty acids. In moderate amounts, they support brain function, skin health, and growth. However, excessive intake, especially without enough omega-3s, can trigger inflammation, which is linked to chronic diseases. Modern diets often provide too much omega-6 compared to omega-3, leading to an unhealthy ratio. Therefore, omega-6 is beneficial in small amounts but problematic in excess.
Cell function: Omega-6s are part of cell membranes, supporting normal growth and repair.
Inflammation balance: They produce signaling molecules that can either increase or decrease inflammation depending on diet balance.
Chronic disease risk: Too much omega-6, compared to omega-3, has been linked to heart disease and arthritis.
Diet imbalance: Processed foods tend to be high in omega-6, pushing intake beyond healthy levels.
