"Actually my personal best is last years 5:11 for 1600 metres, I haven't ran yet this year out doors but I'm going for under 5:00 this year. I'm a competitive mountain biker also- I swim 5 days a week. I can't bench 100 lbs more than my body weight but I can bench somewhere around 250 which is not too shabby- and so far this year I AM training for a local triathlon in the summer- I'm honed!
You obviously are in good shape if you can run a 5:20 mile- but I'm faster lets just hope you can't catch me!"
"I've been Vegan for 14 years. I'm not a healthy vegan as much as an Animal Rights vegan- I basically give in to the ways of convieniance food- french-fries, rice, and smashed potatos- subway, tacotime, and even BK ( gotta love the BKveggie!) I hope to change this habit in the near future as there are plenty of good nutritional vegan foods I can readily eat- I just need to make a habit of going to the grocery store rather than just the corner store-"
At the chemical level there is no distinction between animal derived protein and plant derived protein. "High Protein" is erronously used as short for a "meat" diet, its not the protein that is the problem, rather it is the saturated fats that go along with it.
Actually Bit, I don't know if this is true, but when Soy protein is compared to Fish or beef, Soy lacks a high volume of sulfur-containing amino acid methionine. Sulfer-containing amino acids, particularly methionine and the other cysteine, is an important component for protein synthesis (muscle growth), maintaining the immune system, and the production of glutathione(GSH).
GSH production depends on the sulfur-cantaining amino acids found in beef, fish, eggs, and milk which the vegetable protein lacks. According to Dr. Bill Misner, Ph.D., "GSH protects cells and serves to detoxify a variety of harmful compounds such as hydrogen peroxide, carcinogens, reactive oxygen species, and many others. In particular, GSH is partly responsible for keeping low density lipoproteins (LDL) from oxidizing and clogging our arteries. Several studies have shown soy protein to be inferior to whey for the production of GSH and improvements in immunity."
But, support for the vegan philosophy, According to Dr. Bill Misner, Ph.D. "Soy protein appears to have several other mechanisms by which it lowers cholesterol: isoflavones, endocrine effects, fiber, and saponins. The specific effects of dietary protein on plasma cholesterol concentrations are well documented: animal proteins tend to be hypercholesterolemic as compared to plant proteins. Although this effect of protein source on plasma cholesterol has been shown in many species, the mechanism is not completely understood. Soy has been shown to reduce cholesterol in both man and animals."
Animal Protein Products, (ie. Eggs, Milk, Beef, Fish, etc), may be higher in cholesterol but contains methionine and cysteine which have be shown to lower lipoproteins (LDL) and aids in maintaining a proper immune system.
Soy, has been shown to lower cholesterol in humans, but lacks the necessary sulfer-containing amino acids, which help produce GSH, for maintaining a proper immune system.
From what I understand, Soy protein if fortified with methionine and cysteine, will aid in GSH production, offer a subsitiute protein which is lower in cholesterol, and is easier to digest, when compared to beef and fish.
Which, appears to be a problem for Vegan's since methionine and cysteine is derived from animal protein. But for the rest of us, we have a choice, to either eat meat and run the risk of higher cholesterol or substitute meat with soy/whey fortified with methionine and cysteine which is lower in cholesterol and will have the same properties of animal derived protein.
As I sit and glass, which is common for hunters out west, I have sort of quickly discovered something I never learned when I was younger.
In my youth I had enthusiasm and spirit. In my middle to advancing years I have creaky knees, arthritis, and I tire more easily than I used to. Where I used to sit on the cold hard ground I now look for that soft spot to sooth my tired muscles. That leads me to my tip.
Carry your soft spot with you!
In my pack I carry an air filled, ultralight, camping pad....
