Yolanda Carden, a book publicist, recently sent me an excerpt from a new book called Making A Good Brain Great by Daniel G. Amen, M.D. I thought the article was worth reproducing here:
Seven Simple Brain Promoting Nutritional Tips
Here is the seven step plan to get your diet under control and to use food as brain medicine.
1. Increase Water Intake
Given that your brain is about 80% water, the first rule of brain nutrition is adequate water to hydrate your brain. Even slight dehydration can raise stress hormones which can damage your brain over time. Drink at least 84 ounces of water a day.
It is best to have your liquids unpolluted with artificial sweeteners, sugar, caffeine, or alcohol. You can use herbal, non-caffeinated tea bags, such as raspberry or strawberry flavored, and make unsweetened iced tea. Green tea is also good for brain function as it contains chemicals that enhance mental relaxation and alertness.
2. Calorie Restriction
Substantial research in animals and now in humans indicates that a calorie-restricted diet is helpful for brain and life longevity. Eating less helps you live longer. It controls weight; decreases risk for heart disease, cancer, and stroke from obesity (a major risk factor for all of these illnesses); and it triggers certain mechanisms in the body to increase the production of nerve growth factors, which are helpful to the brain. Researchers use the acronym CRON for “calorie restriction with optimal nutrition,†so the other part of the story is to make these calories count.
3. Fish, Fish Oil, Good Fats and Bad Fats
DHA, one form of omega-3 fatty acids found in fish, makes up a large portion of the gray matter of the brain. The fat in your brain forms cell membranes and plays a vital role in how our cells function. Neurons are also rich in omega-3 fatty acids. DHA is also found in high quantities in the retina, the light-sensitive part of the eye.
Research in the last few years has revealed that diets rich in omega-3 fatty acids may help promote a healthy emotional balance and positive mood in later years, possibly because DHA is a main component of the brain’s synapses.
4. Lots of Dietary Antioxidants
A number of studies have shown that dietary intake of antioxidants from fruits and vegetables significantly reduce the risk of developing cognitive impairment. The research was done because it was theorized that free radical formation plays a major role in the deterioration of the brain with age.
When a cell converts oxygen into energy, tiny molecules called free radicals are made. When produced in normal amounts, free radicals work to rid the body of harmful toxins, thereby keeping it healthy. When produced in toxic amounts, free radicals damage the body’s cellular machinery, resulting in cell death and tissue damage. This process is called oxidative stress.
Vitamin E and Vitamin C and beta carotene inhibit the production of free radicals. The Best Antioxidant Fruits and Vegetables (from the US Department of Agriculture): Blueberries, Blackberries, Cranberries, Strawberries, Spinach, Raspberries, Brussels Sprouts, Plums, Broccoli, Beets, Avocados, Oranges, Red grapes, Red Bell Peppers, Cherries and Kiwis
5. Balance Protein, Good Fats and Carbohydrates
Given the weight issues in my family, I have read many of the diet programs popular in America. Some I like a lot, others make me a little crazy. The idea of eating protein and fat only, avoiding most grains, fruits and vegetables may be a quick way to lose weight, but it is not a healthy long term way to eat for your body or your brain. The best thing in my mind about the Atkins Diet and its many clones is that they get rid of most of the simple sugars in our diets. Diets high in refined sugars, such as the low fat diets of the past, encourage diabetes, tiredness, and cognitive impairment. Yet, to imply that bacon is a health food and that oranges and carrots are as bad as cake seems silly.
The more balanced diets, such as The Zone by Barry Sears, Sugarbusters by H. Leighton Steward and a group of Louisiana based physicians, the South Beach Diet by cardiologist Arthur Agatston, and Powerful Foods for Powerful Minds and Bodies by Rene Thomas make sense from a body and brain perspective. The main principles to take away from these programs is that balance is essential, especially balancing proteins, good fats, and good carbohydrates. Having protein at each meal helps to balance blood sugar levels; adding lean meat, eggs, cheese, soy, or nuts to a snack or meal limits the fast absorption of carbohydrates and prevents the brain fog that goes with eating simple carbohydrates, such as donuts. At each meal or snack, try to get a balance of protein, high fiber carbohydrates, and fat.
6. Pick Your Top 24 Healthy Foods and Put Them in Your Diet Every Week
In order for you to stick with a “brain healthy†calorie restricted nutritional plan you must have great choices. I am fond of the book Super Foods Rx by Steven Pratt and Kathy Matthews. It lists 14 top food groups that are healthy and reasonable in calories. I am going to add several other choices that are especially good for the brain. Choose between these 24 foods each week. They are healthy, low in calories, and help us reach the goals of consuming powerful antioxidants, lean protein, high fiber carbohydrates and good fat.
The American Cancer Society recommends five to nine servings of fruits and vegetables a day. Mixing colors (eating from the rainbow) is a good way to think about healthy fruits and vegetables. Strive to eat red things (strawberries, raspberries, cherries, red peppers and tomatoes), yellow things (squash, yellow peppers, small portions of bananas and peaches), blue things (blueberries), purple things (plums), orange things (oranges, tangerines and yams), green things (peas, spinach and broccoli), etc.
(The list of 24 foods is included in the book.)
7. Plan Snacks
I love to snack; just like to munch on things to get through the day. When snacking it is helpful to balance carbohydrates, proteins and fats. Since I travel frequently, I have learned to take my snacks with me, so I am not tempted to pick up candy bars along the way.
One of my favorite low calorie snacks are dried fruits and vegetables. Not the kind of dried fruits and vegetables stocked in typical supermarkets that are filled with preservatives, but the kind that just have the dried fruit and veggies. A company called Just Tomatoes, from Walnut, California makes great products. When you have dried fruit or veggies—all carbohydrates—add some low-fat string cheese or a few nuts to balance it out with protein and a little fat.

Good article, Ryan. I have a little disagreement with no. 5… I feel that eating a mixture of different foods at each meal is a sure way to indigestion.
Protein meals should be eaten by themselves because they are very difficult and take a long time to digest. If you eat, say, meat with fruit, the fruit will tend to ferment in your stomach while it is waiting for the meat to exit.
This is why people say that fruit makes them feel bad. It’s because they’re eating it on top of a pile of other things. Fruit should always be eaten alone.
Also – and I’m sure you’ll agree with this — simple, refined carbs like DONUTS and other junk, sugary foods should always be avoided, no matter what. :D This is not to be confused with the simple carbs from fruit, which is in a form that nature has provided for our bodies, and is the best form of energy our body can use.
So many people have said they were told to avoid certain fruit, etc because of its high glycemic index. What they don’t understand is that fruit’s simple sugars do not affect the body the way refined sugars do!
Just my 2 cents worth… :) Any thoughts?
I agree with your observations, Sarah. For instance, when I eat fruit, I feel energized; but when I eat foods that contain refined sugars (like whole wheat pancakes with 100% maple sugar), I feel sluggish.
Also, I agree with you on separating different types of food as much as possible. If I am eating fruit or salad with protein, I’ll make sure to eat the fruit or salad first to give it a head start.
Here’s a tip that might not be good for digestion, but can help limit how much you eat at meals, ultimately resulting in weight loss. That is, eat a handful of almonds before a meal. Since they take a while to digest, they will make you feel full and prevent you from eating as much as you normally do.
Just Tomatoes are a great product. I highly recommend the Just Fruit Munchies and the Just Veggies Packs. Aside from advocating just tomatoes in our Healthy Living Blog, we are also one of the few companies that sells them online.
Pleae visit Fit Fuel if you’d like to give them a try – tell us you were referred by this blog, and we’ll include free samples of Larabar and Stretch Island Fruit Leathers, other great products that can help you stay fit and feeling good!
Best,
Luke
