Did you know that researchers find an utterly clear and repeatedly confirmed connection between eating too much sugar (it’s less than one might think!), keeping too much of it in our blood (happens naturally as we age), and then cluttering up our brain …
Feed Your Brain
By: Dr. Deborah Gordon, January 23, 2018
Everything we put in our mouths affects the health of our brains. What we are learning now is that sweets don’t appear to be good for our brains, while healthy fats are excellent brain food. The whole story, however, gets much more complex than that.
Grace Slick was close to my new slogan for baby boomers when she wrote White Rabbit:
When logic and proportion have fallen sloppy dead
And the white knight is talking backwards
And the red queen’s off with her head,
Remember what the dormouse said:
“Feed your head, feed your head.”
Fun fact: Did you know that it was a dormouse, rather than “door mouse”? It is in fact a very cute little mouse with a furry tail, but has no relation to doors.
Feed Your Head
The pills the doctors have for you, when logic, proportion and memory have “fallen sloppy dead” have been based on the theory that amyloid plaques cause Alzheimer’s Disease — the most common cause of memory loss in aging people — accounting for 60-80% of all cases. It is perhaps the most likely cause of dementia when memory loss and difficulty thinking are the only problems, without difficulty moving, controlling your bladder, or speaking. When you can find no other cause for dementia (after looking for vascular disease, Parkinson’s Disease, dementia with Lewy bodies, and more), you are considered to have Alzheimer’s.
Alzheimer’s can strike young people (as in the book and film Still Alice), in which case it is more rapidly progressive, but most commonly affects those 65 and older.
At this point the truly exciting news about Alzheimer’s is not a breakthrough in identifying the cause but rather discovering patterns of disease that have led to insights about a novel and effective treatment program for dementia.
For several years, news has followed the association between sugars and dementia: high levels of sugar – in either the diet or the bloodstream – correlate with increased rates or risk of Alzheimer’s. A study released in 2012, following the connection between a high calorie diet and risk of impaired cognition, asked the question: is it just calories in general, or does it depend what kind of calories we’re talking about? As an observational study, it can only suggest associations or areas for further study, it cannot prove causation, but what it “observed” was worth noting. The study followed almost 1000 elderly subjects for nearly four years and observed that 200 developed symptoms of dementia during that time. Those whose dietary history recorded the highest percentage of carbohydrate calories had a markedly increased risk, almost double the risk of those who ate less carbohydrates. Those who were eating the highest percentage of fats had markedly less, just a dementia rate of 56% of the standard. The avid protein eaters had a bit more, about 79% of the cases, still less than the standard rate. The whopping majority of dementia cases occurred in those eating the most carbohydrates, suggesting that “a dietary pattern with relatively high caloric intake from carbohydrates and low caloric intake from fat and proteins may increase the risk of dementia in elderly persons.”
There are more dietary observational studies as well as many focused experiments wondering just what is the “magic ingredient” that gives or protects from dementia. Many have elaborated the specific dynamics on a microscopic physiological level, finding tiny alterations that seem to have an effect. The magic happens when you take them all together: the multitude of factors that affect brain health suggests that pathology of Alzheimer’s Disease seems to represent a systematic or program failure, rather than a single targeted agent. In short, the cumulative research raises the question of taking a systems approach to the disease.
A systems approach is one that looks at the wide array of causes and considers them together rather than imagining one more important than the others. A systems approach has been used successfully with other diseases, particularly in a public mixed with private health arena. You can check your blood pressure at the drug store, not just at the doctor’s office. You can hear from your doctor as well as hearing reminders almost everywhere that you shouldn’t smoke! So, without having to understand the details of the highly technical neurological science involved in Alzheimer’s, it is relatively straightforward to grasp the concept that a broader collection of individual interventions , when taken together, might comprise a “team” effort to reverse a devastating disease process.
Dr. Dale Bredesen and John Varghese have done amazing work in this realm, publishing a theoretical article detailing the history and the rationale for a life-choices systems intervention model. Impressive: it sounds great, but does it work?
Luckily for us they were working in the theoretical and real worlds at the same time. In October of 2014, they published a report of ten subjects with whom they were able to apply some of 22 identified potential beneficial actions their folks could take. One very advanced person failed to show any benefit, but the results with nine of the ten were truly impressive. Three of their personal stories are detailed in the article here.
There are drugs that claim to show some benefit with Alzheimer’s patients, but none of them claims to nor has been ever seen to reverse the disease. Some symptoms or expressions of the disease may be temporarily controlled, but cognitive function does not return as it did with nine of Dr. Bredesen’s ten subjects.
What does this mean?
The implications are two: one for research and one for the public. There are certainly intriguing suggestions for research scientists to pursue: confirm or refute! Meanwhile, there is every good reason for clinicians who are comfortable with the types of interventions used to add them to the tool bag of treating dementia today.
In fact, there is good reason to share this information – healthful for more than just cognitive function – with all of our aging patients. The biggest problem, as I see it – is that some of the interventions will be novel to physicians (“How does one normalize Pregnenolone levels?”) Another consideration is that the scope of the program is broad-reaching and comprehensive, which could be daunting to people with perfectly intact memories. For people living a “standard American lifestyle, complete with cheerios for breakfast,” a hefty number of changes are demanded to steer towards a healthier future for your brain.
Here’s a summary of the 21 interventions.
- Reduce nutritional inflammation: choose a low-carb, possibly grain-free, and high-fat eating plan. Avoid allergenic foods, reduce sugars!
- Clean your brain. Fasting is a good break for the brain, allowing it to “clean itself out”: fast for at least 12 hours a day (between the end of dinner and the start of breakfast).
- Stress management. Reduce your level of stress with yoga or meditation. (My favorite is an iPhone app called BrainWave, that sends slightly different sound track to each earphone and has a relaxing effect on my brain.)
- Brain recovery and cleansing happen during sleep. Optimize sleep with a goal of 8 hours nightly. Rule out sleep apnea if you have sleep troubles, and supplement with tryptophan or melatonin if needed.
- Exercise. Aim for 30-60 minutes, 4-6 days a week, is great. More is better, so long as you allow for true rest days between vigorous workouts.
- Reduce brain toxins; specifically keep homocysteine <7.0. The first supplements to try are methylated versions of B12 and folate, as well as B6 in the Pyridoxal-5-Phosphate form. (These are all combined in Thorne Research Basic Nutrients III vitamin available in our store, paired up with the necessary co-factors to enable those B vitamins to work well.)
- Feed the nervous system in general. Keep B12 levels in the upper half of the normal range.
- Measure and manage inflammation. Check and normalize lab tests, including hsCRP and the albumin/globulin ratio.
- Hormones. Balance and replace hormones, including
- Optimized thyroid hormones
- Estrogen (estradiol, not Premarin), progesterone (not Provera) and testosterone – it’s not too late!
- Pregnenolone and cortisol
- Digestion must function normally. Evaluate gastrointestinal health and repair as needed.
- Prevent scarring in the brain. Reduce amyloid beta formation with curcumin and/or ashwaganda.
- Reasoning mechanisms. Take supplements that enhance cognitive function: Bacopa monniera or magnesium-l-threonate.
- Vitamin D. Optimize vitamin D3 levels between 50-100 ng/mL
- Brain repair. Increase neurotrophic growth factor: H. erinaceus or acetyl-l-carnitine
- Support brain structure. Structural components of the brain need feeding, too, with citicoline or phosphatidylcholine, DHA, or magnesium-l-threonate.
- Anti-oxidants. Optimize antioxidants using foods (wild blueberries) and supplements (mixed tocopherols, n-acetyl cysteine, and alpha lipoic acid.)
- Zinc and copper are key. Optimize your zinc/copper ratio, keeping the zinc a bit higher than the copper.
- Mitochondrial support. Optimize mitochondria: lots of vegetables, fruits and colors … and supplements such as ubiquinol, alpha lipoic acid, selenium, zinc, and others.
- Mental focus. **Increase focus with pantothenic acid.
- Toxicity? Rule out heavy metal toxicity. Treat if present.
- Beneficial brain foods. Ketones are great for the brain, whether they come from a ketogenic diet, or supplementation with MCT Oil, or by prescription: Axona.
Some of these supplements are available to you in a simple stroll through either our online store or your local health food store. They are usually regarded as safe for generally healthy people. If you have any health concerns, OR if you want to pursue the program in its full complexity, I highly recommend you work with an experienced practitioner who knows how to test, supplement and prescribe for these 20 recognized areas relevant to brain health.
