You may already know I’m a big fan of acai berries. The little South American powerhouses pack quite a nutritional punch:
Acai has been shown to triple antioxidant capacity in humans.(1)
It’s rich in oleic acid. And in lab tests, oleic acid supports lower cholesterol and fatty acid production.(2)
Flavonoids and other plant chemicals – like those found in Acai – have been linked to improved memory and learning in several animal studies.(3)
Acai berries even provide a little resveratrol.
Of course, most people connect acai with weight loss. It’s a popular and healthy addition to many weight loss formulas.
But if you’ve been taking acai to lose weight, three new studies hint that you may be doing a lot more for your health. And the news is all good.
If you want to hang on to your brainpower, you may have a new reason to love acai berries.
Hydrogen peroxide (H2O2) can do a lot of oxidative damage to your cells. But when researchers in Brazil gave acai to rats, they found H2O2 produced far less damage in the rats’ brains.(4)
This effect hasn’t been shown in humans yet. But human tissue often reacts similarly to rat tissue. And that has me excited. Because this study could be the first step towards helping preserve brainpower.
In our second study we’ll look at another critical issue: DNA.
Less DNA Damage
DNA damage can result in cells that divide abnormally – or are unable to divide at all. So avoiding damage to your DNA is obviously good for your health.
A team at the University of SÃ£o Paulo tested acai against a powerful DNA-damaging drug, doxorubicin. When they gave acai to mice, they found the drug did far less damage to the DNA in liver and kidney cells.(5)
And they found that mice given a little acai every day suffered the least damage.
Again, these results still have to be tested in people… but it’s hard not to get excited. DNA damage may be directly linked to the aging process. Slowing DNA damage could lead to looking and feeling more youthful – years beyond our current expectations.
Which brings us to our third new study…
“Switch on” All the Right Genes
You probably think of fruit flies as pests. But researchers at the National Institutes of Health may have just made them your friends. Here’s why:
The researchers fed fruit flies an unhealthy high-fat diet. Some of the flies also got acai pulp. The flies fed acai consistently lived longer.
The team fed other flies a diet designed to cause oxidative stress. Some of the flies also got acai pulp in their diet. Once again, the flies that ate acai consistently outlived those that didn’t.
The team discovered that acai switched on genes linked to healthy levels of stress and switched off certain “unhealthy” genes.(6)
It’s a long way from flies to people, but the researchers stressed the potential of their findings. And I agree.
We have some distance to go before acai is declared the next superfood. But we already know acai provides many health benefits.
If you’ve considered trying these powerful berries, I think it’s a good idea. Even if only one of these new studies translates successfully to humans, you’ll be way ahead of the game.
