Eat Your Way Smart with a Brain Food Diet

A diet is simply a planned way of eating. Most people go on a diet to  lose weight. Some people adopt a particular diet because they have food allergies, or are eating to  control their cholesterol  or  digestive disorders.

But few people say they are on a “brain food diet” to get smarter and develop a healthier brain! And that’s a shame, because changing the way you eat can have a huge impact on how well your brain functions.

If you eat to give your brain the optimal nutrition it needs, here is what your smart food diet will look like.

Eat Smart: Balance Your Macronutrients

“Eat a balanced diet” we’re all told,  but what does this mean?  No one seems to agree and the experts change their recommendations all the time.

When I refer to a balanced diet, I mean one that contains adequate amounts of the three macronutrient groups – carbohydrates, protein and fat. Our brains need the nutrients in all three of these groups, preferably at every meal.  Eaten together, this balance minimizes wild dips in blood sugar levels, which can wreak havoc with your mental state. Individually, here’s what each of these food groups can do for your brain.


Your brain creates hundreds of chemicals called neurotransmitters. Examples of neurotransmitters include dopamine, serotonin, and endorphins. These compounds enable brain neurons to communicate with each other. Neurotransmitters are largely made up of amino acids, which come from protein.

The healthiest sources of protein are  grass fed meats,  poultry, wild fish, dairy, eggs,  whey protein  and legumes. Most Americans get adequate protein except for possibly picky eaters, vegetarians that are not careful about their protein intake, or people with poor digestive assimilation.


Your brain is largely made up of fat – 60% by volume. So if anyone calls you a “fat head”, it’s actually true!

It’s not an exaggeration to say that the quality of your brain cells depends on the quality of the fats you eat. That is why you should focus on brain healthy foods high in good fats such as avocados, olives, nuts, and seeds, and fatty fish like salmon, tuna, or mackerel. Be sure to buy  genuine wild-caught fish, not farm raised.

The  omega-3 fatty acids  found in these are particularly helpful for your brain. They can help with mental clarity, concentration and focus, while preventing mood swings and depression.

Getting some healthy fat at every meal keeps your blood sugar levels stable and keeps you satisfied longer.


Carbohydrates have gotten a bad rap. Just as there are good fats and bad fats, there are good and bad carbs as well.

Your brain can’t store energy, so it depends on a continual supply of glucose released from carbohydrates. Complex carbohydrates, such as those found in vegetables and fruits give your brain the sustained energy it needs.

There is growing evidence that  grain of all kinds may be harmful to your health, and that  wheat – even whole wheat  – is the worst of all.

Don’t be reluctant to eat starchy vegetables like potatoes, yams, carrots, winter squash or beets.  They play a big part in a healthy diet. They’ll help your blood sugar stay stable and keep you from getting hungry while delivering the steady stream of glucose that your brain needs. And contrary to what you may have heard, they won’t make you gain weight.


Antioxidant-Rich Fruits and Vegetables

Simple carbohydrates such as sugar or white flour cause wild fluctuations in blood sugar levels — first up and then down.  When your brain’s level of glucose is low, either from not enough good carbs or too many bad ones, it can lead to mood swings, irritability, tiredness, mental confusion and impaired judgement. This is why people on low carb diets often aren’t a lot of fun to be around.

Your brain is highly susceptible to free radical damage  because it uses so much oxygen. Foods high in antioxidants are usually the most colorful fruits and vegetables. The U.S. Department of Agriculture’s list of top ten antioxidants contains six types of berries. So  eat plenty of berries  knowing they are some of the best brain foods around, and they happen to be delicious as well.

Eat plenty of foods rich in  vitamin C and vitamin E. These two nutrients have been found to work synergistically to be particularly helpful in reducing free radical damage. The best sources of vitamin C are citrus fruits and highly colorful peppers. Vitamin E is plentiful in nuts and seeds, and the oils derived from them.

Spice it Up

Herbs and spices are another category of foods for the brain. Be sure to cook with ginger, turmeric, saffron, sage, paprika and chili. These work by acting as powerful antioxidants and  reducing inflammation.

Bake with cinnamon or sprinkle it on everything from applesauce to oatmeal. Even just a whiff of this spice is believed to stimulate your brain.

“Brain Drains”

There are some  foods that are a drain on your brain. Caffeine and sugar seem to lessen the effects of some neurotransmitters in the brain. Alcohol, if consumed beyond moderation, can do the same.

Unhealthy trans fats found in fried, fast, and processed foods are so unhealthy, they are actually banned in some places. This type of fat has been shown to impair memory, cause brain atrophy, and increase the risks of dementia and Alzheimer’s.

Eating too much salt seems to correlate with reduced cognitive performance too.  Food additives such as MSG  and  NutraSweet  are believed to contribute to migraines, autism, ADD and Alzheimer’s disease.

smart brain food - waterYour Brain Needs Water

While water is not a brain “food”, no discussion about the optimum brain diet would be complete without mentioning it. Your brain is 80% fluid. Being dehydrated actually shrinks your brain, and temporarily impacts how well it works.

Fortunately, once you get rehydrated your brain function should get back to normal quickly. However, chronic dehydration is suspected to be responsible for premature aging and a host of health problems including Alzheimer’s.

To figure out how much water you need each day, take your weight in pounds and divided by 2. That is the roughly the number of ounces you need to drink each day under normal circumstances. Learn  exactly how much water  you should be drinking here.

Eating a healthy diet of lean protein, healthy fats and complex carbohydrates, seasoned with the right spices, is the best diet you can feed your brain to keep it in top form now, and ward off potential brain problems in the future.
