The term “fatty acid” may hold an unhealthy connotation for some people, but fats and fatty acids are important to our overall well-being. There are “healthy fats” and “unhealthy fats."
It has been identified that consuming saturated fats and trans fats may pose a risk to your health. You’ll want to limit your intake of these fats, but healthy fats are important during all stages of life, especially for children and older people.

Healthy fats and omega-3 fatty acids

Healthy fats include monounsaturated fats and polyunsaturated fats, which supply your body with essential nutrients. An especially important type of fat are omega-3 fatty acids.
Omega-3 fatty acids are well-known for their heart-related benefits. According to the Cleveland Clinic, omega-3 fatty acids may lower your risk of cardiovascular disease, blood clots and death by abnormal heart rhythms. They may also lower your blood pressure.
On a microscopic level, omega-3 fatty acids are crucial to your cell membranes. They help cells interact with each other and keep the structure of your cells healthy. So, from big to small, omega-3 fatty acids are necessary to support the health of your whole body. What about their benefits for your brain?

Omega-3 and your brain

Omega-3 fatty acids are concentrated around the eyes and brain. The brain health benefits have been displayed by numerous studies.
Here’s what a healthy intake of omega-3 fatty acids can do for your brain:
  • Aids in learning and memory
  • Promotes healthy blood flow in the brain
  • May reduce the risk for age-related cognitive decline
  • May lower risk of developing Alzheimer’s disease

Foods with omega-3 fatty acids

  • Salmon
  • Mackerel
  • Herring
