Are there extra benefits from
avoiding “bad fats”?
1 gram of fat = 9 calories
1 gram of carbohydrate = 4 calories
Physical Activity
University of Illinois, 120 adults

2. Carry massively heavy luggage.
3. Run for the plane.
Beginning Aerobic Exercise
Begin with 10-minute brisk walk.

The Bilingual Advantage
Languages protect your brain.
Delays cognitive decline by ~5 years.

Notas do Editor

  1. Hi Neal: Sorry it took so log, but here are images of a plaque and a tangle from one of the world`s leading authorities on AD and he is happy to let you use them.  Plaques are extracellular, in contrast to tangles that are initially intraneuronal but persist after neuron death and disappearance as “ghost” or “tomestone”  extacellular tangles sitting where the neuron cell bodies that had once contained them used to be but no longer are.  Larry From: Eliezer Masliah [mailto:emasliah@ucsd.edu] Sent: Wednesday, April 25, 2012 9:59 PM To: Lawrence A.Hansen Subject: Re: Pictures of plague and tangle Hi Larry please find enclosed, plaques are with anti-Abeta and tangles with phospho Tau Beta amyloid only reveals itself as filamentous at the resolution level of the electron microscope. The images I sent are brown because an antibody to the beta amyloid protein was attached to a brown chromagen  to label the  otherwise nearly invisible fibrils.  Larry

  4. Show butter, cheese, meat Ask Dr. Morris for actual percentages of AD risk, so I can say, with this much sat fat, your risk is this. Take out this fat and it’s reduced to this.
  5. Could show an array of foods, in line from lowest to highest sat fat content.
  6. Show snack foods contain trans fats
  7. Could show an array of foods, in line from lowest to highest sat fat content.
  8. Show foods: You’ll find traces of vitamin E in broccoli, spinach, sweet potatoes, mangoes, and avocados. And there is much more in nuts and seeds, especially almonds, walnuts, hazelnuts, pine nuts, pecans, pistachios, sunflower seeds, sesame seeds, and flaxseed. Black walnuts 8.1 Sesame seeds 8.0 Pecans 6.9 Pistachios 6.4 English walnuts 5.9 Flaxseed 5.7 Sunflower seeds 7.4 Almonds 7.3 Almond butter 6.9 Hazelnuts 4.3 Pine nuts 2.6 Brazil nuts 1.6
  9. Researchers at Oxford University went a step further, testing folate, vitamin B6, and vitamin B12 in older people who were having memory problems that were sufficient for a diagnosis of mild cognitive impairment.10 As you will recall, that means they had significant forgetfulness but were otherwise fine for the moment. The researchers gave everyone a set of cognitive tests. Then, over the next two years, the participants started a daily regimen that consisted of 800 micrograms of folate, 500 micrograms of vitamin B12 and 20 milligrams of vitamin B6, all of which are well above the recommended dietary allowance for these vitamins and more than one would typically get from foods. The effects were remarkable. High homocysteine levels fell sharply, and many people found their memory improving significantly. Accuracy on testing was improved by as much as 70 percent. And brain scans showed that the B-vitamins also helped protect against brain shrinkage over time. de Jager CA, Oulhaj A, Jacoby R, Refsum H, Smith AD. Cognitive and clinical outcomes of homocysteine-lowering B-vitamin treatment in mild cognitive impairment: a randomized controlled trial. Int J Geriatr Psychiatry. 2011; Jul 21. doi: 10.1002/gps.2758. [Epub ahead of print]
  10. Figure 4. Selected subtraction MRI scans. The images are from the baseline scan with colour superimposed to show the brain tissue change over the following two years. Colours show expansion (red/yellow) or contraction (blue/light blue) of the brain of 0.3 to 1.0 mm, with the lightest colour indicating the biggest change. (A) Subtraction image of female participant in the placebo group, age 79 years, with baseline tHcy of 22 mmol/ L, whose tHcy concentration increased by 8 mmol/L over two years. Atrophy rate was 2.50% per year. Atrophy most strongly appears here as enlargement of the ventricles. (B) Subtraction image of female participant in active treatment group, age 72 years, with baseline tHcy of 24 mmol/L at baseline, whose tHcy concentration decreased by 12 mmol/L over two years. Atrophy rate 0.46% per year. There is no clear visible pattern of atrophy. doi:10.1371/journal.pone.0012244.g004
