Meal size and frequency affect neuronal plasticity and vulnerability to disease: cellular and molecular mechanisms. Mattson MP, Duan W, Guo Z. Laboratory of Neurosciences, National Institute on Aging, Gerontology Research Center, Baltimore, Maryland 21224, USA. Although all cells in the body require energy to survive and function properly, excessive calorie intake over long time periods can compromise cell function and promote disorders such as cardiovascular disease, type-2 diabetes and cancers. Accordingly, dietary restriction (DR; either caloric restriction or intermittent fasting, with maintained vitamin and mineral intake) can extend lifespan and can increase disease resistance. Recent studies have shown that DR can have profound effects on brain function and vulnerability to injury and disease. DR can protect neurons against degeneration in animal models of Alzheimer's, Parkinson's and Huntington's diseases and stroke. Moreover, DR can stimulate the production of new neurons from stem cells (neurogenesis) and can enhance synaptic plasticity, which may increase the ability of the brain to resist aging and restore function following injury. Interestingly, increasing the time interval between meals can have beneficial effects on the brain and overall health of mice that are independent of cumulative calorie intake. The beneficial effects of DR, particularly those of intermittent fasting, appear to be the result of a cellular stress response that stimulates the production of proteins that enhance neuronal plasticity and resistance to oxidative and metabolic insults; they include neurotrophic factors such as brain-derived neurotrophic factor (BDNF), protein chaperones such as heat-shock proteins, and mitochondrial uncoupling proteins. Some beneficial effects of DR can be achieved by administering hormones that suppress appetite (leptin and ciliary neurotrophic factor) or by supplementing the diet with 2-deoxy-d-glucose, which may act as a calorie restriction mimetic. The profound influences of the quantity and timing of food intake on neuronal function and vulnerability to disease have revealed novel molecular and cellular mechanisms whereby diet affects the nervous system, and are leading to novel preventative and therapeutic approaches for neurodegenerative disorders.

Studies always go back and forth... and get really confusing:

Don't you think that it's WHAT you put in your body that matters. Now if i keep the red meat protein and fat out of my system, and eat lots of veggies, rice , beans, whole grains and moderate red wine (cleans the arteries right out, not so good for the liver in excess), along with unsaturated oils, moderate aged cheeses, and plenty of good old time herbs, and heavy on the fruit (the so called mediterranean diet) that this can be better than starving oneself. My italian side of the family, well they are all octogenarians or better, and my UK side of the family are all dead. This could be genetic, but from what we know about beta protein and plaques ,tangles , and blocked arteries, i' m just a bit sceptical about calorie reduction as my italian side are all a few pounds overweight and my UK side are all skinny rails. Just one person's opinion.

There's a theory that different blood types (because of heredity linkage) have different nutritional needs. While I think it is a little simplistic, it does make a lot of sense to think that cs's jolly Italian ancestors would have had more babies eating pizza and thereby have given him more pizza genes. Similarly, if grandma was an Eskimo thriving on blubber then I'm gonna be healthier on a high fat diet. Darwinianism can be abused like anything else, but the big idea that healthy individuals leave more babies is a no-brainer.
I thrive on red meat. Heck, I started salivating just typing the darned sentence! Some do well with milk. Others had ancestors who did not keep herds. Same with grains. As if things weren't complicated enough. -Rick

In any event... there are studies to cover every contingency today.
There is a new study showing distilled spirits actually can reduce diabetes risk: http://www2.potsdam.edu/hansondj/InT...137438309.html What works for mice, does not always translate to humans. This deprived food intake gets alot of attention. But long term results in humans are lacking.

Isn't comparing studies about what kinds of foods you eat to studies about biochemical results stimulated by when you eat kind of like comparing apples to oranges?
Neither kind of study paints a whole picture; what and when you eat are not mutually exclusive. The validity of eating a certain diet (CS's position) is not changed or threatened by this study that suggests that when you eat is also important. The message for me is that the main thing we are learning from research is that PD is complex, our bodies are complex, and there is a lot left to learn.

Eventually, for some of us - both what and when matter. The only way I can be guaranteed not to go off is to eat very little at a time and watch the dairy and protein. So for example, one of my favorite meals is a tuna salad sub and ice cream for desert. After eating this, I can kiss my day good bye because I'm full and full of the wrong food.

Is the tuna salad sub from Subway? I love those! And I'm hooked on several Ben & Jerry's flavors right now; they're always on sale at the grocery store I frequent.

Rick, you made me think of this site {below}
- I have the book and a lot of the foods mentioned as good/bad for my blood type fit for me. I feel better or worse in general depending on some food choices. http://www.dadamo.com/ [ Welcome to the first science that understands you as a biochemical individual. Following decades of ongoing research and clinical work, Dr. D’Adamo created The Blood Type Diets, a way of eating and living that has transformed the health of millions. His first book, the New York Times best-seller Eat Right 4 Your Type, started a health revolution that continues unabated over ten years later. Now, with more than 3 million copies in print in over 50 languages, Eat Right 4 Your Type celebrates its 10th year as an unprecedented non-stop bestseller in hardcover.] FAQs- http://www.dadamo.com/faq/smartfaq.cgi

"Parkinson's Disease: Reducing Symptoms with Nutrition and Drugs" by Dr. Geoffrey Leader, MB ChB FRCA and Lucille Leader, Dip, ION
Like the idea of genetics determining your ideal diet, it also makes sense that careful fasting might be good for us. Evolving on the Plains with the great herds, the pattern would tend to be binge and fast. That would give the body a chance to clean house.
