Omega 3-s also have a couple additional benefits for your brain.
For one thing, they may slow age-related mental decline and help ward off Alzheimer’s disease (4Trusted Source, 5Trusted Source, 6Trusted Source, 7Trusted Source).
On the flip side, not getting enough omega-3s is linked to learning impairments, as well as depression (3Trusted Source, 8Trusted Source).
In general, eating fish seems to have positive health benefits.
One study found that people who ate baked or broiled fish regularly had more gray matter in their brains. Gray matter contains most of the nerve cells that control decision making, memory and emotion (9Trusted Source).
Overall, fatty fish is an excellent choice for brain health.
SUMMARY:Fatty fish is a rich source of omega-3s, a major building block of the brain. Omega-3s play a role in sharpening memory and improving mood, as well as protecting your brain against decline.
If coffee is the highlight of your morning, you’ll be glad to hear that it’s good for you.
Two main components in coffee — caffeine and antioxidants — help your brain.
The caffeine in coffee has a number of positive effects on the brain, including (9Trusted Source):
- Increased alertness: Caffeine keeps your brain alert by blocking adenosine, a chemical messenger that makes you sleepy (10Trusted Source, 11Trusted Source, 12Trusted Source).
- Improved mood: Caffeine may also boost some of your “feel-good” neurotransmitters, such as serotonin (13).
- Sharpened concentration: One study found that when participants drank one large coffee in the morning or smaller amounts throughout the day, they were more effective at tasks that required concentration (14Trusted Source).
Drinking coffee over the long term is also linked to a reduced risk of neurological diseases, such as Parkinson’s and Alzheimer’s (9Trusted Source).
This could at least be partly due to coffee’s high concentration of antioxidants (15Trusted Source).
SUMMARY:Coffee can help boost alertness and mood. It may also offer some protection against Alzheimer’s, thanks to its caffeine and antioxidants.
