quit eggs due to high methionine, in favor of whey.

Do you eat meat?

i eat red meat, maybe once a month. i do eat fish though. i eat a quasi-mediterranean diet, without the cheese/dairy.

Wow, can you post a link? Thanks.

we did this in another thread:

you can see lentils and some foods have very low amounts of methionine. typically, i will eat no fish, no red meat, no poultry for one day, and only get by on mostly vegetarian diet. the next day ill eat a bit of fish w/ a meal.

i'm still changing things around, based on any new info acquired. i dont think i have 'all the answers' by any means. but i think a lower methionine/quasi-mediterranean/CR diet makes the most sense to me.

I put together this chart comparing the ratio of amino acids to methionine on a gram/gram basis, comparing eggs and bacon.

I'm just thinking out loud here. Bacon and eggs both have methionine, but the ratios of the other amino acids that they contain to their methionine content are different. Maybe there is an amino acid that helps mitigate the effects of methionine (like glutamic acid or glycine, whose ratios to methionine in bacon are higher than eggs).

Interrelationship of Dietary Glycine, Methionine and Vitamin E in the Rat:

Growth of rats fed a 10% soy diet with 0.9% methionine was significantly reduced when glycine was added to this diet. No difference in growth was observed with glycine in the presence of 1.8% methionine. Glycine partially alleviated the severe toxic effect of 3.6% methionine.

So, is methionine particularly needed for young organisms (rat pups and of course chicks), but less so for adults?

Well the list of foods I can eat seems to continue shrinking.. I eat 3 whole eggs and one extra white every day as my last meal of the day.

I was on this routine for months before having blood work done and both of my cholesterol numbers came back around ~50, on the lower side of the spectrum. I don't have a baseline and I was also taking in a decent amount of fish oil and niacin at the time so those might have lowered it.

Eggs, no thanks (as soon as I get over my addiction to eggs, that is). Start reading from left to right (those are alluded posts over at CR society): they're bad, bad and bad

"Bad" perhaps for people with extraordinarily good lipid profiles (like those on MR's preferred form of CR). Otherwise, I don't think he would object, for example, to one egg per day for the rest of us. (Eggs are cheap too.)

I'm also hesitant to eliminate too many different sources of protein, being left, for example, with nothing but protein powders as a main source of protein. Until better data is available, I prefer an approach wherein I get protein from a variety of sources (bit of meat/fish, 1 egg, protein powders, etc.).

For safety, the egg does need to be cooked in some way, preferably at <= boiling point of water for short time. This also prevents the fats in egg from being too quickly absorbed - something I noticed when studying my after-meal TGs: uncooked yolks caused the greatest spike in after-meal TG of any complex food I consumed.
