I would not trust the Memory of a Vegan. First of all...although a Human can survive on a Strict Diet of specific Fruits and Vegetables and Grain and Bean and Bean products such as Tofu....a Human Being was not evolved to be a Vegan.

Memory and Memory function as well as Immune system failure, inability to properly rebuild muscle and a host of other issues are direct results over time of even the Strictest of the Best Vegan Nutritional Guidlines. This is talking about a TRU VEGAN....no animal products, eggs, cheese, milk...etc.

One of my Familes Companies is in several Medical Fields and I have extensive knowledge of what a Human Body can or cannot have replaced in Protein Vegetation as apposed to actual consumption of Fish, Beef, Polltry, Pork, Venison...my favorite and...etc.

Even liquid Protein Suppliments are made from ammino-acids broken down from animal byproducts. The Human Body was evolved to be Omniverous and if a person desires to either put on Muscle or loose weigh...all they simply have to do is eat EXACTLY what a Chimp would eat in the Wild. We can cook it of course but the idea is NO MACHINE PROCESSED FLOUR that makes bread. The Number 1 reason people have High Cholesterol is that they eat White Bread made from grain that has been ground so fine that it turns into Cholesterol in the Body and blocks our Arteries since it is not a Whole Grain.

It is also imparitive for a persons Mental Abilities to consume ANIMAL PROTIENS AND FATS...there is more Fat in a Salmon Steak than two scoops of Ice Cream but it is GOOD FAT....and we need it. It cannot be replaced by a Vegan Diet...even if Soy Products may have some of these needs...the way it is digested and absorbed....much of nutritional and caloric absorbtion occurs not just in the stomach but in the Intestinal System.

Take it from me...I am muscular and lean and never get sick. I bounce back from injuries and even at my age...I can RUN 5 miles and Jog about 20. I eat a wide variety of Organic Fruits and Vegetables from my Garden and Grill Venison and Beef steaks as well as a wide variety of store bought and Hunted Poltry...just have to watch out for the #6 shot BB's..LOL! I swim and I dive and remain active at all times. I drink with my band mates but since I have alot of muscle...muscle metabolizes alchohol at 10 times the rate of Fat...so I am never wasted...just having a good time. Don't put your trust in the pale looking pasty skined...dry and dull hair...cloudy eyed...twig like...[Tell Tale sign of Malnutrition]...white spots on the finger nails...Bankers Memory.

Trust the Guy who is having a small Steak with a side of Broccoli and a Salad with Vineger and Extra-Virgin Olive Oil...no potato, no cheese or crutons or fake bacon bits in it and uses a wedge of Lemon to flavor the Broccoli. His or Her drink?....a Light Beer or a Wine or Tonic and Gin, Vodka...etc...or Soda Water...my Favorite. This person will have the Memory Capacity you desire...NOT A VEGAN! Split Infinity

Im a meat eater, here they did a study, they followed 3 people for 3 months.
With full blood tests and medical checks constantly like 10 times a day.
One a massive meat eater another a Vegetarian who didn't eat meat but still ate dairy seafood and eggs etc.
And another who was a strict Vegan who ate no animals products at all.
And they found the healthiest one was the Vegetarian, only slightly healthier than the meat eater, but the Vegan scored low was last on the healthy scale.
I bet if the meat eater ate a little less meat he would have been the same as the Vegetarian.
Also the Vegan was a cyclist was constantly exercising much more than the others yet still was far more unhealthy than them.
