To Avoid Alzheimer’s: Avoid Bacon, Beer, Pesticides, and Air Pollution

In honor of Alzheimer’s Awareness Month, the Alzheimer’s Association has put together a new video.

The video promotes the propaganda that genes cause Alzheimer’s.

Nothing could be further from the truth.

And it’s not the message I want to send to my patients.

I believe in the brain’s power to heal itself if you give it the proper nutrients. In fact, I’ve seen it many times over the years in my own patients.

In a moment, I’ll give you three of the best nutrients that heal your brain.

But first I want to prove to you, beyond a shadow of a doubt, that Alzheimer’s is not caused by genes. And that it is directly linked to our toxic environment.

For example:

  • A study at Rutgers University found people with Alzheimer’s had four times the levels of the pesticide DDT in their blood.1
  • Toxic chemicals in our food and personal care products called nitrosamines have been shown to break down our energy-producing mitochondria, leading to major neurological damage.2
  • Autopsies of young adults and children who lived in polluted Mexico City revealed highly elevated amyloid plaque levels in their brains.3
  • Mice exposed to air pollution developed up to 129% more amyloid plaque.4
  • And 21% of new Alzheimer’s cases are directly linked to pollution.5

Of course you’ll never hear about how you can protect your brain from the Alzheimer’s Association or any other government-funded Big Pharma puppet. It’s not in their own interest to promote non-drug interactions.

Here are a few of the best nutrients I’ve found to boost brain function and keep your mind sharp. I’ve used these with great success with my own patients to improve — and in some early cases reverse — their cognitive decline.

They also help prevent and even reverse more serious conditions like dementia, Alzheimer’s and Parkinson’s disease.

Three Nutrients You Can Take Today to Make Your Brain a Healthy Powerhouse

  1. Gotu Kola – The Ancient Ayurvedic brain plant. In Bali, I found gotu kola (Centella asiatica) growing in an ancient Hindu religious site. The natives sometimes call it “the student herb,” because it sharpens the mind.This ancient herb is a brain-boosting marvel. It can help spur growth in brain cells.Animal and cell studies show that gotu kola can trigger the repair of damaged brain cells. It also restores higher cognitive function.6 When choosing a gotu kola supplement, look for one with more of the active components. Select one that is standardized to the asiaticosides or asiatic acid.I recommend my patients use gotu kola in three ways.
    • As an extract. Take 10 drops or from 10 to 20 mL per day.
    • As a powdered herb (available in capsules). Take 400 mg to 600 mg, three times a day.
    • As a dried herb. You can make a tea of the dried leaf, three times daily. Use up to 6 grams of dried leaf.
  2. Acetyl-L-Carnitine – The great brain multi-tasker. Acetyl-L-carnitine (ALC) is an amino acid. Many studies show that it can prevent brain aging and slow the progress of existing brain diseases.7 ALC promotes brain health by restoring the function of nerve growth factor (NGF). NGF is a protein produced in your brain. It controls the growth and maintenance of neurons.As you get older your levels of NGF go down. Research shows that the decline in NGF leads to a major drop in the way brain cells perform. And the loss of this growth factor can lead to degenerative brain diseases.8 Acetyl-L-carnitine helps reverse this drop. At the same time it exerts a positive effect on the survival and growth of your neurons.9 Like NGF, your levels of acetyl-L-carnitine decrease with age. That can put you at risk for brain degeneration.10 But you can take ALC as a supplement. I suggest taking at least 500 mg of ALC every day on an empty stomach. Look for a formula with only L-carnitine and not D, L-carnitine. The D form is synthetic. Also, liquid acetyl-L-carnitine is more absorbable than powders and capsules.
  3. DHA – The fat that fuels your brain. Your brain is 60% fat and omega-3s make up 40% of that. Omega-3 fats combat brain shrinkage and memory loss.And a specific kind of omega-3s called docosahexaenoic acid (DHA) can even help slow the progression of Alzheimer’s disease.11 DHA is the fat that’s also the main structural component of your brain tissue. So it makes sense to get more in your meals to replenish it.The best sources of omega-3s (especially DHA) are animal products like fish, eggs and meats. Oily fish, like mackerel, herring, tuna, salmon, trout and sardines, are the richest source. But over the years, I’ve found that it’s almost impossible to get enough omega-3s from your food alone. You’ll probably need to supplement. Be careful though…Most fish oil pills are from polluted waters. That’s why I recommend krill oil and calamari oil to my patients. The tiny shrimp-like krill don’t live long enough to absorb large amounts toxins. And calamari live miles below the ocean, far from the pollution on the surface. Take 4 grams to 6 grams per day to realize the brain benefits.
