What are Omega-3 Fatty Acids?
Omega-3 fatty acids are a type of polyunsaturated fat that is essential for human health. They are found in fish, seafood, and some plant-based foods. Omega-3 fatty acids play a vital role in many bodily functions, including:
- Heart health: Omega-3 fatty acids help to lower blood pressure, reduce triglycerides, and increase HDL (good) cholesterol. They also help to prevent blood clots and stroke.
- Brain health: Omega-3 fatty acids are essential for brain development and function. They help to improve memory, learning, and mood. They also protect against neurodegenerative diseases such as Alzheimer’s and Parkinson’s disease.
- Eye health: Omega-3 fatty acids help to protect against macular degeneration and cataracts. They also improve vision acuity and reduce dry eye symptoms.
- Immune function: Omega-3 fatty acids help to boost the immune system and reduce inflammation. They also help to protect against autoimmune diseases such as rheumatoid arthritis and lupus.
- Skin health: Omega-3 fatty acids help to keep skin healthy and hydrated. They also help to reduce wrinkles and age spots.
