Turmeric is a yellow spice often used in curry that contains the anti-inflammatory antioxidant curcumin. Curcumin is capable of crossing your blood-brain barrier, which is one reason why it holds promise as a neuroprotective agent in a wide range of neurological disorders.
Research has shown that curcumin may help inhibit the accumulation of destructive beta amyloids in the brain of Alzheimer’s patients, as well as break up existing plaques.3Curcumin has even been shown to boost memory and stimulate the production of new brain cells, a process known as neurogenesis.
Also remarkable, animal research suggests another bioactive compound in turmeric called aromatic-turmerone can increase neural stem cell growth in the brain by as much as 80 percent at certain concentrations.4 Neural stem cells differentiate into neurons and play an important role in self-repair.
The findings suggest aromatic-turmerone may help in the recovery of brain function in neurodegenerative diseases such as Alzheimer’s and stroke (provided the effect also applies to humans).
A word to the wise… some curry powders may contain very little curcumin compared to straight turmeric powder, so choose the latter for the best health benefits.
2. Wild Alaskan Salmon
The omega-3 fats found in wild Alaskan salmon help fight inflammation throughout your body, including in your brain, and offer numerous protections to your brain cells.
For instance, a study in the journal Neurologyfound “older women with the highest levels of omega-3 fats… had better preservation of their brain as they aged than those with the lowest levels, which might mean they would maintain better brain function for an extra year or two.”5
In separate research, when boys were given an omega-3 supplement, there were significant increases in the activation of the dorsolateral prefrontal cortex part of the brain.6
This is an area of your brain that is associated with working memory. They also noticed changes in other parts of the brain, including the occipital cortex (the visual processing center) and the cerebellar cortex (which plays a role in motor control).
You can get omega-3 fats in therapeutic doses by taking a supplement like krill oil. But if you’re looking for a food source, wild Alaskan salmon (along with sardines and anchovies) is among the best.
Many are concerned about radiation from Fukushima contaminating the salmon, but our primary source is Vital Choice and they regularly check for this radiation and never find it in their salmon.
3. Broccoli and Cauliflower
Choline intake during pregnancy “super-charged” the brain activity of animals in utero, indicating that it may boost cognitive function, improve learning and memory, and even diminish age-related memory decline and the brain’s vulnerability to toxins during childhood, as well as conferring protection later in life.7 Eggs and meat are other food sources of choline.
Broccoli offers additional benefits as well, including the anti-inflammatory flavonoid kaempferol and three glucosinolate phytonutrients that work together to support your body’s detoxification processes.8
Walnuts are good sources of plant-based omega-3 fats, natural phytosterols, and antioxidants, and have been shown to reverse brain aging in older rats. DHA, in particular, is a type of omega-3 fat that’s been found to boost brain function and even promote brain healing, although it’s more plentiful in animal-based omega-3 sources, like krill and wild Alaskan salmon, as opposed to walnuts.
Walnuts contain a number of other neuroprotective compounds as well, including vitamin E, folate, melatonin, and antioxidants that lend even more brain benefits. Research shows walnut consumption may support brain health by increasing inferential reasoning in young adults,9 for instance.
Another study found that consuming high-antioxidant foods like walnuts “can decrease the enhanced vulnerability to oxidative stress that occurs in aging,” “increase health span,” and also “enhance cognitive and motor function in aging.”10
Celery is a rich source of luteolin, a plant compound that may calm inflammation in your brain, which is a primary cause of neurodegeneration. Luteolin has also been linked with lower rates of age-related memory loss in mice, and older mice fed a luteolin-supplemented diet scored better on learning and memory tasks.11 In addition to celery, peppers and carrots are also good sources of luteolin.
6. Coconut Oil
The primary fuel your brain needs for energy is glucose. However, your brain is able to run on more than a single type of fuel, one being ketones (ketone bodies), or ketoacids.Ketones are what your body produces when it converts fat (as opposed to glucose) into energy.
The medium-chain triglycerides (MCT) found in coconut oil are GREAT source of ketone bodies, because coconut oil is about 66 percent MCTs. Medium-chain triglycerides go directly to your liver, which naturally converts the oil into ketones. Your liver then immediately releases the ketones into your bloodstream where they are transported to your brain to be readily used as fuel. While your brain is quite happy running on glucose, there’s evidence suggesting that ketone bodies may actually help restore and renew neurons and nerve function in your brain, even after damage has set in.
Therapeutic levels of MCTs have been studied at 20 grams per day. According to research by Dr. Mary Newport, just over two tablespoons of coconut oil (about 35 ml or seven level teaspoons) would supply you with the equivalent of 20 grams of MCT, which is indicated as either a preventative measure against degenerative neurological diseases, or as a treatment for an already established case.12
The antioxidants and other phytochemicals in blueberries have been linked to improvements in learning, thinking and memory, along with reductions in neurodegenerative oxidative stress. They’re also relatively low in fructose compared to other fruits, making them one of the healthier fruits available. Wild blueberries, which have high anthocyanin and antioxidant content, are known to guard against Alzheimer’s and other neurological diseases.
Wild blueberries have even been shown to reduce some of the effects of a poor diet (such as high blood pressure systemic inflammation). In one recent animal study, wild blueberries reduced the pro-inflammatory effects of a poor diet as well as prevented high blood pressure, which would be beneficial for your brain health as well.
