5 Diet Tips to Boost Your Memory

5 Diet Tips to Boost Your Memory

Doctors have been recommending dietary changes to their patients with such conditions as diabetes, high cholesterol, and high blood pressure for years. Soon they may be doing the same for patients suffering from poor memory function.

That’s because a host of new clinical studies have all found that specific nutritional interventions can significantly improve memory function in patients with Alzheimer’s disease (AD) and those with mild cognitive impairment.

But you don’t have to have Alzheimer’s to benefit from the new findings. Eating a brain-healthy diet can also help those of us who, as we age, notice that our mind and memory just aren’t as sharp as they used to be.

Here are 5 memory-boosting dietary recommendations, based on the latest scientific research and clinical experience treating patients with AD and MCI.

1. Proportion your fat-carb-protein intake.

Every day, make sure that you aim for 25% of your total calories from brain-healthy good fat, which includes olive oil, avocados, certain nuts, natural peanut butter, certain seeds, and certain fish. Limit your intake of bad fats (most fast foods, anything hydrogenated, dried coconut, butter, animal fats, milk chocolate and white chocolate, and cheese). Consume 30-45% of your daily calories from complex carbohydrates (fruits, vegetables and whole foods that are low on the glycemic index), and wean yourself off high glycemic carbs (sugars, high-fructose corn syrup, processed cereals and grains, anything baked, whole milk and cream, ice cream and sorbet, crackers, salty snacks such as chips and pretzels, and anything made with white flour). Finally, get the other 25-35% of your calories from high-quality lean protein.

2. Boost your brain nutrients.

Omega-3 fatty acids (DHA and EPA) are essential for memory function and brain health. Most of us don’t get enough from dietary sources (such as fish), so consider high-quality, pure fish oil supplements that contain a minimum of 250 mg of DHA in each capsule, and aim for 1,000-1,500 mg of DHA daily if approved by the treating physician. Antioxidant-rich foods are also great for mental function. Some of the best are berries, kale, 100% pure unsweetened cocoa powder, mushrooms, onions, beans, seeds, sardines, herring, trout, and Alaskan wild salmon. Finally, ensure adequate intake of folic acid, B6, B12, and vitamin D in particular. If you’re not eating vitamin-rich foods on a regular basis, it’s good to supplement as needed in pill or liquid form.

3. Eat whole foods, Mediterranean style.

A brain-healthy Mediterranean-style diet includes fruits and vegetables, lean protein (fish, chicken, and turkey); low-fat yogurt and cheeses; and grains, nuts, and seeds. Stay away from red meat and processed foods. Get in the habit of eating whole foods. What are whole foods? They’re foods that have only one ingredient–for example, strawberries, broccoli, or barley. If you must have a convenience (manufactured) food on occasion, find those packaged, canned, and frozen items with the fewest ingredients–especially ingredients that you readily recognize and understand.


4. Enjoy coffee and pure cocoa.

Good news for coffee lovers! Caffeinated coffee, 1-3 cups early in the day, may be beneficial over time to your brain. Studies done in Europe over several years demonstrate that men who drank coffee regularly for many years showed less of a decline on memory tests than those who did not drink coffee. More good news: An exciting new study released August 2012 showed that patients with mild cognitive impairment who had regular intake of the strong antioxidants found in pure dark cocoa powder had improvement in memory function.


5. Fast 12 hours at night.

If you routinely wake up at 6 a.m., try to eat your last meal at 6 p.m. the night before. There is scientific evidence that substances called ketone bodies, which are produced when there are no carbohydrates to burn for fuel, may have a protective effect on brain cells. This means no late-night snacking between dinner and breakfast.

Great article! I primarily eat whole foods and totally stay away from red meat and processed foods! Very interesting about the ketone bodies and why we shouldn't eat late night snacks! Thank you.

Food nutrition is a key element in maintaining our overall physical well being. We must always pay attention to the foods that we eat because they will eventually impact our health, for better or for worst. We have more information available about the benefits of every particular food group than we’ve ever had before, which is why we also have a bigger responsibility than ever before to make assertive and responsible food choices.

I am glad to see the recommendation for DHA at 1000-1500 mg. instead of the mere 240 mg. as needed to sustain minimum brain function.

I have read(entirely)research papers regarding the function o f DHA and DPA in the body.

There is a very positive, tested multiple times, correlation between brain(and heart)health with an intake of 950mg. of DHA daily.

If you take fish oil, pay no attention to the EPA numbers. It's only value is its ability to convert to DHA in the body. Of its self, it does absolutely nothing in the body.

DHA is the major player for optimal health, hands down. The good newsm, is if you can't afford supplemetation with a Norwegian DHA supplement, eating any kind of cold water fish twice a week will give you very good, study proven, similar benefits.

This includes that can of sardines sitting in your cupboard.
