Altzheimer's/Stress Relationship - Dr. Mercola

     Dr. Mercola has an interesting article on the relationship of stress to the onset of Altzheimers.  I particularly found it interesting because I have thought a lot about this.  One of my best friends developed Altzheimers after realizing she could no longer care for her handicapped daughter and would have to put here in a care facility.  (My friend was in her late 70's at the time.)  She told me she had always said she would rather die than put Marilyn in a home, but that was the only solution.  She developed Altzheimers shortly after.  
     I don't know whether I agree totally with his conclusion that it is always preventable, but I do know our diets are such that we don't give our bodies much to work with when we get into stressful situations.  I would like to improve my chances.
     You can read the entire article here.  I'm including his suggestions for helping to prevent the disease below because I want to be able to reference them easily.

". . .Knowing that it is a preventable disease puts the power into your hands. People who experience very little decline in their cognitive function up until their deaths have been found (post-mortem) to be free of brain lesions, showing that it's entirely possible to prevent the damage from occurring in the first place… and one of the best ways to do this is by leading a healthy lifestyle.

• Avoid Sugar and fructose. Ideally, you’ll want to keep your sugar levels to a minimum and your total fructose below 25 grams per day, or as low as 15 grams per day if you have insulin resistance or any related disorders.
• Avoid gluten and casein (primarily wheat and pasteurized dairy, but not dairy fat, such as butter). Research shows that your blood-brain barrier, the barrier that keeps things out of your brain where they don’t belong, is negatively affected by gluten. Gluten also makes your gut more permeable, which allows proteins to get into your bloodstream, where they don’t belong. That then sensitizes your immune system and promotes inflammation and autoimmunity, both of which play a role in the development of Alzheimer’s.
• Optimize your gut flora by regularly eating fermented foods or taking a high quality probiotic supplement.
• Increase consumption of healthful fats, including animal-based omega-3. Beneficial health-promoting fats that yourbrain needs for optimal function include organic butter from raw milk, clarified butter called organic grass fed raw butter, olives, organic virgin olive oil and coconut oil, nuts like pecans and macadamia, free-range eggs, wild Alaskan salmon, and avocado.
Also make sure you’re getting enough animal-based omega-3 fats, such as krill oil. (I recommend avoiding most fish because, although fish is naturally high in omega-3, most fish are now severely contaminated with mercury.) High intake of the omega-3 fats EPA and DHA help by preventing cell damage caused by Alzheimer's disease, thereby slowing down its progression, and lowering your risk of developing the disorder.
• Reduce your overall calorie consumption, and/or intermittently fast. Contrary to popular belief, the ideal fuel for your brain is not glucose but ketones, which is the fat that your body mobilizes when you stop feeding it carbs and introduce coconut oil and other sources of healthy fats into your diet. A one-day fast can help your body to “reset” itself, and start to burn fat instead of sugar.
As part of a healthy lifestyle, I prefer an intermittent fasting schedule that simply calls for limiting your eating to a narrower window of time each day. By restricting your eating to a 6-8 hour window, you effectively fast 16-18 hours each day. To learn more, please see this previous article.
• Improve your magnesium levels. There is some exciting preliminary research strongly suggesting a decrease in Alzheimer symptoms with increased levels of magnesium in the brain. Unfortunately, most magnesium supplements do not pass the blood brain levels, but a new one, magnesium threonate, appears to and holds some promise for the future for treating this condition and may be superior to other forms.
• Optimize your vitamin D levels with safe sun exposure. Strong links between low levels of vitamin D in Alzheimer's patients and poor outcomes on cognitive tests have been revealed. Researchers believe that optimal vitamin D levels may enhance the amount of important chemicals in your brain and protect brain cells by increasing the effectiveness of the glial cells in nursing damaged neurons back to health.
Vitamin D may also exert some of its beneficial effects on Alzheimer's through its anti-inflammatory and immune-boosting properties. Sufficient vitamin D is imperative for proper functioning of your immune system to combat inflammation that is also associated with Alzheimer's.
• Keep your fasting insulin levels below 3. This is indirectly related to fructose, as it will clearly lead to insulin resistance. However other sugars (sucrose is 50 percent fructose by weight), grains and lack of exercise are also important factors. Lowering insulin will also help lower leptin levels which is another factor for Alzheimer’s.
• Vitamin B12: In addition to the research presented above, a small Finnish study published in the journal Neurology¹²also found that people who consume foods rich in B12 may reduce their risk of Alzheimer's in their later years. For each unit increase in the marker of vitamin B12, the risk of developing Alzheimer's was reduced by two percent. Remember, sublingual methylcobalamin may be your best bet here.
• Eat a nutritious diet, rich in folate, such as the one described in my nutrition plan. Vegetables, without question, are your best form of folate, and we should all eat plenty of fresh raw veggies every day. Avoid supplements with folic acid, which is the inferior synthetic version of folate.
• Avoid and eliminate mercury from your body. Dental amalgam fillings, which are 50 percent mercury by weight, are one of the major sources of heavy metal toxicity. However, you should be healthy prior to having them removed. Once you have adjusted to following the diet described in my optimized nutrition plan, you can follow the mercury detox protocol and then find a biological dentist to have your amalgams removed.
• Avoid aluminum, such as antiperspirants, non-stick cookware, vaccine adjuvants, etc.
• Exercise regularly. It's been suggested that exercise can trigger a change in the way the amyloid precursor protein is metabolized,¹³ thus, slowing down the onset and progression of Alzheimer's. Exercise also increases levels of the protein PGC-1alpha. Research has also shown that people with Alzheimer's have less PGC-1alpha in their brains and cells that contain more of the protein produce less of the toxic amyloid protein associated with Alzheimer's. I would strongly recommend reviewing the Peak Fitness Technique for my specific recommendations.
• Avoid flu vaccinations as most contain both mercury and aluminum, well-known neurotoxic and immunotoxic agents.
• Eat blueberries. Wild blueberries, which have high anthocyanin and antioxidant content, are known to guard against Alzheimer's and other neurological diseases. Like any fruit though, avoid excesses here.
• Challenge your mind daily. Mental stimulation, especially learning something new, such as learning to play an instrument or a new language, is associated with a decreased risk of Alzheimer's. Researchers suspect that mental challenge helps to build up your brain, making it less susceptible to the lesions associated with Alzheimer's disease.
• Avoid anticholinergic and statin drugs. Drugs that block acetylcholine, a nervous system neurotransmitter, have been shown to increase your risk of dementia. These drugs include certain nighttime pain relievers, antihistamines, sleep aids, certain antidepressants, medications to control incontinence, and certain narcotic pain relievers.
Statin drugs are particularly problematic because they suppress the synthesis of cholesterol, deplete your brain of coenzyme Q10 and neurotransmitter precursors, and prevent adequate delivery of essential fatty acids and fat-soluble antioxidants to your brain by inhibiting the production of the indispensable carrier biomolecule known as low-density lipoprotein."
