For those who say they get their protein from plants - I'm interested in

knowing exactly what this means. Aside from soy and legumes (such as beans)

combined with rice, and the recent news I posted about chick peas and

hummous (which is made from chick peas), I'm not aware of significant

amounts of proteins found in other plants. So just what does " protein " from

plants mean, you guys?

And pardon my ignorance.

The usda database shows most veggies have on the order of 1 gm per oz.

Fruit about .5 gm per oz. If you eat just veggies and fruit, you have to eat

a lot of food to get enough energy, especially if low fat. So the protein is

surprisingly high overall. Let me point out that lettuce is 31% protein if

you don't count the water. How does a cow grow to 1200 # in 2 yrs, just

eating grass ( which might be 7% P)? It eats a LOT of grass. And you don't

have to eat beans either. I think the mistake that " vegetarians " make is

assuming they have to eat soy or other beans to replace the meats they leave

out. Sear's basically ignores the P in veggies and it's a little bothersome

for me trying to follow his regimen.

As I look at my intake today, based on Amino acid RDA's from

Sherman's desk reference,

I see I'm at more than 200% on essential AA's. Total P is 50gms. If I left

out the eggwhite and milk I'd still be over 100% of RDA's for essential AA's

except methionine, with total P at 23 gms. My personal choice is to add

ffmilk for the Calcium and methionine to increase the essential AA's without

adding so much to total P. I could add 8 oz of pinto beans and forgo the

milk if I were a vegan.

Regards.

Francesca,

My experience is similar to JW's. If you enter a day's worth of meals in

DWIP, try leaving out any major animal source of protein but include at

least 6 servings of vegetables, 3 serving of fruit, 2 - 3 cups of any grain

and 1 - 2 Cups of any legume (peas, beans, lentils, etc). When you bring up

the nutritional analysis, you might be surprised to see how much protein is

totaled and the high quality (100% of each essential amino acid). Remember

that the amino acids in animal protein came originally from plants: it was

just re-arranged into muscle tissue. It is easy to supplement this amount

with soymilk, tofu, etc if you are trying for a relatively high level of

protein as on the zone diet. For levels of protein found in the

Ornish/Biosphere diet, you really don't need to even use soy or animal

protein.

Some vegetables are surprisingly high in protein like broccoli but

overall the total and high quality of a day's vegetable protein intake kind

of sneaks up on you because it is so well distributed.

Calcium is avail in plants as well as milk, but I do use ffmilk for Calcium.

You may have noticed there's a constant argument whether Ca is absorbed from

milk or plants. Studies I've read indicate 20% for milk/cheese, and 17% for

greens. I take some extra Ca. I can't find where osteo is caused by lack of

ingestion of Ca at the levels we usually get. It's a parathyroid hormone

thing.

JW,

Don't forget that there are low oxylate greens like kale and mustard

greens (and probably other wild ones) that have calcium absorbed at rates of

50 - 60%. See the work of Connie Weaver at Perdue University. Most of her

work is published in the Am J of Clin Nutr.

This is very interesting, especially since non-animal sources are usually

much lower in calories. However Walford does recommend higher amounts of

protein, it seems from animal sources (fish, egg whites, FF yogurt etc) in

T120Y Diet; or at least the meals he lists as examples do. Aren't there

important nutrients non-animal sources are missing such as B-12, omegas (in

fish) etc? Isn't it much more difficult for us " lazy " people to balance our

diets without animal protein. Remember Warren 's posts about osteo?

Comments?

Francesca,

You are probably right in suggesting that " lazy " people might have

trouble with a vegan diet because it is quite far from the mainstream AL

diet that most of us grew up on. Eating vegan does require a serious

committment to eating vegetables, fruits, nuts and reasonable amounts of

grains and beans. Simply taking a " salad & pasta " approach as some teenage

vegan girls do will lead to trouble with many nutrients that are usually

gotten from meat and dairy. Consuming a lot of empty calories from pastries

and candy could also be pretty problematic.

Someone with a committment to CR, however, is probably in a better

position esp if they are using a dietary database like DWIP to evalute their

diet. In that case the nutrients in a vegan diet are laid out quite clearly

and adjustments can be made just as with an omnivore diet. Vit B-12 used to

be widely available (it is a bacteria) to all humans until sterile food

preparation sharply limited it. It is available from animals only because

they eat dirty plants that are rich in B-12. Vegans either get B-12 from a

Mult-V or from nutritional yeast. I have done previous posts about the

availability of protein and calcium in a well constructed vegan diet.

I think, that, as the split between the two Walfords possibly

demonstrates, CR can be done omnivore or vegan and IMO the difference has a

lot to with taste buds. Of course, as a vegan, I will say that I believe

that this diet offers the best protection against chronic disease like

cardio-vascular and cancer esp if you are trying to heal and recover from

either.

When you see comments on either list that question the validity of a

vegan diet I suggest that you assume that they are talking about a poorly

constructed vegan diet. This is Rae's postion, i.e. he has indicated

in his posts that a vegan diet must be well constructed. Of course, IMO this

is equally true of an omivore CR diet. From what I am learning on these

lists, once you go to 1800 c or less, you really do have to know what you

are doing.

I have been toying with a vegan diet for the last year

or so. I have ear problems, which I believe are

related to sinus problems. I have dropped milk

products.

Most grains are high in calories in relation to their

protein and other nutrient values. Wheat germ has the

highest protein and nutrient values for a grain.

According to " Diet for a Small Planet, " wheat germ has

a higher protein usability than soybeans. I eat wheat

germ as a primary protein and few other grain

products. I eat it with a vegetable and salsa.

Soybeans are a mainstay for vegan diets. The

questions raised on this list about soybeans, however,

make me a little wary of them. I still eat soybeans

every day as a primary protein. I make soybean chili.

One of the amino acids in soybeans that is unbalanced

on the high side is glutamic acid. This appears to be

convertible in the body to glutamine. Glutamine has

health benefits, and is not just burned as an unusable

AA.

Brewer's yeast is a third vegan product that is high

in protein (for a vegetable product) and low in

calories. I eat brewer's yeast every day as a primary

protein. I mix it with ground flax seed in tomato

juice. Brewer's yeast, like soybeans, is unbalanced

high with glutamic acid.

I try to get at least 100 grams of vegan proteins a

day from the above three sources. This costs less

than 1200 calories. Taking into consideration the

lower quality of the protein, I believe this assures

me 60 grams of quality protein. This meets the

Walford recommendations for a 150 pound body.

Occasionally, I supplement with omega 3 fish. I don't

even count the protein from other vegetable sources.

I take B12 and Calcium supplements.

I have never noticed any fingernail or hair problems.

I seem to have pretty good endurance, but I don't run

5 miles to test it. I haven't broken any bones,

lately. My ear problem (tinnitus) may be somewhat

relieved.

I hope dropping dairy does help with your tinnitus. I do think that you

could probably be more relaxed about your protein intake. What is your daily

calorie intake? Are you eating at least 6 servings of veg/day?

My guess, based only on what you have mentioned, is that you may be

getting over 90 g of quality protein since soy and wheat protein complement

nicely. You can download a free test copy of DWIP from Walford's site and

enter a days food intake to analyse you amino acid breakdown. The latest

estimate I have read for vegan protein intake is .09 g of protein for ea 1.0

kg of body weight unless you are exercising strenuously or eating a very,

very low calorie diet. The .09g figure allows for lower absorption of

protein (compared to an omivore diet) due to fibre, phytates, etc.
