Some of us are still trying to get the hang of quarantine, while others are gearing up to head back into the office after having established a work from home routine.


Either one; you may need some extra tips on how to stay focused and gain energy through the foods you eat.


We know foods play a significant role in our mood, focus, and memory, but which food might help boost our memory or/and concentration?

  Let’s look at three foods more closely that can help boost your brain and memory.

Coffee
  • Coffee in moderation has many health benefits, a lower risk of some diseases, high levels of antioxidants, and helps burn fat. 


  • Coffee helps us become more alert, gives us the energy to be prepared for meetings, or getting tasks done at home. [1]


  • Coffee also helps improve performance on tasks. One study found small amounts throughout the day of coffee showed similar effects compared to drinking one large number at one time. [2]


  • Coffee’s caffeine is available in other forms than just coffee drinks, you can try dark chocolate, tea, decaf coffee, or matcha! 

Blueberries
  • Blueberries are rich in antioxidants and anti-inflammatory properties. [3]


  • A study done on older adults found that there was a significant increase in brain activity observed compared to the placebo group.[4]


  • According to another study, blueberries, along with other berries, can offer a neuroprotective effect (protecting the brain). Blueberries can directly improve neuro cell signaling and communication. [5]


  • Add some blueberries on top of your smoothies, yogurt, oatmeal, cereal, or just have them as a snack. They’re in season! 

Turmeric

The main active ingredient in turmeric is curcumin, which is a strong antioxidant and anti-inflammatory effect. 


  • Curcumin has neuroprotective properties, can improve cognition, and help with depression.[6]


  • Curcumin can also help with the development of new brain cells [6]


Many other foods help boost your brain and memory like fish, broccoli, dark chocolate, nuts, oranges, eggs, and more. I encourage you to find a new brain food to incorporate into your diet this month! Switch it up and feed your brain 😊
