My question is: Where are you getting your seafood? A lot of shellfish (shrimps and scallops especially) are treated with sodium tripolyphosphate, a neuro-toxin which can cause the symptoms you describe. If you're getting your seafood from the store, this could be the case. If you're getting your seafood fresh from the ocean, it is most likely a shellfish allergy.

PliestoceneDream, you are confusing hydrogen bonds with covalent bonds.

I'm not, but even if I were, it would make little difference as far as the denaturation of proteins is concerned: the covalent bonding and specific amino acid sequence may not have changed, however, the functional conformation of the protein is destroyed.

Fructose and Glucose have different covalent structures.

Yes, as seen here: http://cdavies.files.wordpress.com/2009/01/glucose-fructose-sucrose.jpg

Fructose and Glucose are, for all intents and purposes, the same chemical. However, they are structured differently (known as an "isomer") and thus behave differently within the body. Starch and cellulose are made of the same chemical, but are arranged differently, causing them to behave quite differently in the body

The same is true of proteins that have been denatured via cooking. There is no "just" about it - when the protein changes, either in the amino acid sequence or via denaturation (ie, a degradation of the functional conformation), the protein no longer "works". In fact, you have actually changed the protein into an "isomer" - the same chemical formula/amino acid sequence, but completely different structure and thus function (in most cases, no function).

So while cooking may not break apart the covalent bonds of a protein, it also doesn't "just" change the hydrogen bonds; the function and action of the protein is completely dependent upon those hydrogen bonds. Without them, the protein unravels - permanently (except in the laboratory where the process can sometimes by reversed). Generally speaking, you cannot unscramble an egg. This is why fevers are so dangerous.

If lectins are destroyed via cooking (which they are), then they are no longer doing the "bad things" they supposedly do to the body, and the residual amounts left over are in an quantity known as a "therapeutic level" - the level which does not cause toxicity or ill effects in the host, but has positive health effects (in this case, destruction of immature cancer cells).

Lectins are protein fragments.  I'm always skeptical of claims that they are "destroyed" in cooking.  Cooking typically does not change the chemical structure of the food.  It can coagulate proteins, but after digestion, they'll still be broken apart, and the lectins may be problematic again.

1) Lectins are not "protein fragments".

2) Cooking destroys proteins. A protein is made up of a chain of amino acids, known as a "polypeptide". Because of hydrogen bonding, these chains fold upon themselves, creating a 3-dimensional structure (the tertiary structure of the protein). Sometimes, more than 1 chain of polypeptides fold together, such as in hemoglobin, creating a quaternary structure. A protein is 100% dependent upon it's amino acid sequence as well as it's conformation. When a protein is heated, as in cooking, the molecules it's made of begin to vibrate and shake more frequently. Eventually this causes the protein to "denature" or unfold. The protein is more or less "de-activated". When your body digests protein, it breaks the peptide bonds, freeing the individual amino acid groups.

3) If a lectin is just protein, and the protein is broken apart by digestion, how would the lectin "be problematic again"?

Did you know that glucose and fructose have the same chemical formula? c6h1206. However, they are bonded together (shaped) differently, and as such behave differently within the body. The same is true of proteins. Did you know that starch is made up of exactly the same glucose molecules as cellulose? The only difference is the shape of the meta-molecule due to the difference in bonding site.

Crap.

Well my only source of milk is in my coffee.

Will that destroy me?

I think I could get used to black coffee...

« on: August 31, 2010, 10:41:41 AM »
I drink coffee. 1 - 2 cups a day. I have no desire to stop. I love the taste, smell, and physiological/psychological effect.

I also take a Calcium/Magnesium/Zinc/Vitamin D supplement. This is my "athletic performance supplement" because after the stress reaction in my left shin, I don't want to take any more chances! I also drink Vitamin D milk and I get plenty of sun. So I know I'm not low on D, and I get 100% RDV of CalMagZinc.

But I've also read that coffee de-mineralizes your bones.

Considering I do not drink soda, or eat sugar, or smoke, is coffee an acceptable indulgence or will it be my undoing?

I can run an 8 minute mile now.

I can jog continuously for an hour now.

I have not had a PVC in weeks.

I take Calcium, Magnesium, Vitamin D and Zinc supplement (I noticed an endurance increase within 2 days of starting on the zinc)

I know right?

A few months ago recruiters were all "boohoo we don't have enough people for the war effort" and they turn me down cuz of small holes in my ears.

Pretty stupid.

I was even talking to my recruiter about becoming a SWIC or a SARC, which are in demand right now.

Foolishness.

Well I have a stress fracture now, so I'm focusing on swimming. I went too hard for too long and made big leaps without building up.

The Navy will not take me after all because my wears are gauged (can barely fit a pencil in them, haven't worn jewelry in years). So instead of spending 1grand on a operation to fix them, I'm just gonna take out a few loans and go to school.

Boo.

Still gonna do fitness though. Gonna aim for 100 pushups / 100 situps / 100 squats / 20 pullups each in 2 mins.

Want to run 2 miles in 18:00
And swim 500m in 10:00.

Had some family troubles... had to get away.

Ran/walked/jogged between 6-8 miles in about an hour. Not sure exactly so I say 7 in an hour. Still not to bad.

Airway felt fine, near the end had some angina.

I managed 1.25 miles in just over 10 minutes.

I have a great pace and I make good time.

The only problem is, the other day I went for a run and it was chilly outside. Well after about 6 minute my lungs felt all heavy and congested and I coughed up so much phlegm I could not believe. Run over, failed.

I'm hoping hoping it's not asthma. And if so I hope it's temporary. I used to be a pretty heavy smoker for a few years, but I quit 2 weeks ago, maybe that has something to do with it?

Yes. And for the first time in a long time I stopped running because my legs were tired, not because I was out of breath and my chest burned.

W007

You should have seen me. I walked/ran 3.75 miles. Hopefully by July I'll be doing mile runs, and August before I ship out 2 - 3 mile runs.

I got some gatorade. It's has sugars and carbs and I can't eat paleo right now, so I'm gonna only drink half a bottle a day since I'm getting more carbs than I want as it already is.

My mom also took it upon herself to get me one of those VitD, Calc, Magn sups. It says take 3 a day but I'm only gonna take 1 or maybe even half of one.

Hi Nutmeg,

I have not been diagnosed with the PVCs. I had all sorts of wires hooked up to me, sonar signals, and you name it done to my heart. They found no abnormal structures, no damage, no nothing. So it must be either a biochemical mechanism causing it or perhaps an extra sinus nerve? I'm not sure.

I do know I have them because I feel them, VERY distinctly, when they happen. Babump...babump...babump......... BUMP!... babump...babump...

I notice they're a lot worse when I first start exercising. When I lived in Cali a few years ago, I took a PT class and a swimming class with my GF. I would show up to PT 30 minutes early and run up, walk down, run up, walk down, the stairs inbeween the bleachers. Then the coach would show up and have us... run up and down bleachers. And do "mountain climbers", and pushups, and squats, and then he'd have us run the track. Then we'd go to swim class, and I was the top swimmer in the class. I would get the occasional PVC during all of this (mostly on the track, never swimming), but after a while I got them less.

Still wouldn't be good if I was doing SEAL stuff. Can PVCs kill you? I hope not.

Electrolytes you say? Tell me more about the sea salt, etc. I was gonna aim for magnesium, but if I take a sup, the Navy will notice. If I just eat a little salt, they probably won't even realize...
