“Once we hit our late twenties, the brain’s aging process begins and we begin losing neurons – the cells that make up the brain and nervous system. By our sixties, our brains have literally begun to shrink.” ~ Canyon Ranch Institute: ‘How Your Brain Changes With Age’
Not too long ago, most people – including brain experts – thought that loss of brain cells meant the loss of intellect and that loss of intelligence was both inevitable and irreversible. All of this, of course, was before the discovery of neuroplasticity, the almost superhuman ability of the brain to grow neural connections throughout life.
Dr. Michael Merzenich, one of the pioneers of neuroplasticity research, explains this incredible capability of the brain:
“Your brain is plastic. You have the power within, at any age to be better, more capable, continuously growing a progressively more interesting life. If you’re in (cognitive) decline, you have great resources that can help you sustain – indeed, even regrow – your neurological abilities in ways that can help assure that your active brain shall last as long as your physical body.”
Now, because of aging’s cumulative effects on the brain, there is no possible way to regrow every neuron that’s ever spouted, but that’s not necessary. The most important thing, according to Dr. Merzenich, is that we continue to challenge, nourish, and protect our noggin.
If you do these three things, you’ll be able to care for your brain well beyond what is needed for healthy cognitive function.
The Role of Food
As you well know, pretty much everything that you put into your body has a physical and psychological impact. We’re either adding to our brainpower or subtracting from it. Wolf down four pieces of pizza, and you’ll probably feel a bit less sharp; eat an orange and you may experience a slight brain and energy boost.
If you’re interested in maximizing your intellectual capabilities and want to use food as a means for doing so, this article is for you. Only the foods that produce a significant (and well-documented) cognitive benefit are worthy of mentioning here.
Here are the best foods for your brain according to doctors and other experts:
A.k.a. “brain berries,” blueberries are perhaps the most potent brain food of all. First, foremost, and most importantly, blueberries protect your brain from the damage of free radicals and age-related cognitive disorders such as dementia.
In one interesting study, researchers conclude that blueberries increased “both the learning capacity and motor skills” of aging rats. These findings show that eating at least one cup of fresh blueberries per day may reap some serious brain benefits.
Besides blueberries, avocados may just be the next best food for your brain. “I don’t think the avocado gets its due,” says Steven Pratt, MD, author of Superfoods RX: Fourteen Foods Proven to Change Your Life.
The most notable discovery is that the monosaturated fats in avocados significantly increase blood flow to the brain as well as also lower blood pressure. The former effect enhances thinking skills, while the latter safeguards them against decline. Healthy as avocados are for the brain, they’re pretty high in calories. Add just 1/2 avocado to one daily meal, maximum.
3. Nuts and Seeds
Per WebMD, an ounce of almonds, Brazil nuts, cashews, flaxseed, filberts, hazelnuts, sesame seeds or sunflower seeds may help halt some of the inevitable cognitive declines of aging. Scientists attribute this neuroprotective effect to vitamin E.
