What I learned….

…in vet school today.
Fat+sugar (specifically fructose from sucrose) = fatness.
Would share with you the mechanism of the whole thing but it’s a blur on the slide……something about activating, lack of feedback inhibition, excess of acetly CoA –> fat blah blah blah blah. Apparently Fructose is more lipogenic than glucose.
Why this applies to veterinary medicine.
More fat in meat = better fat. More fat = better USDA grade = more money.
How do we get all this fat into beef? We give them corn (which is somehow magically = to fructose)! Which they are not designed to eat, so we give them additives to change the ruminant biochem. Since they have a lipogenic diet, it results in marbled beef = higher profits.
I don’t have the nutrition and biochem background to critically exam this info, but it was interesting and I’m inclined to think it’s true.
Eating fat isn’t necessarily the problem –> it’s the fructose/corn that’s the issue. And I’m not thrilled that the supermarket beef has a bunch of fat that wouldn’t be there if the cows weren’t fed an abnormal diet…..Abnormal diet in cows = abnormal composition of meat = what in my body? I’m currently eating grass fed raised beef that I buy from my pastor and it’s about time to drop the cash for another 1/2 of a cow…..I always wonder whether it’s REALLY worth it (even though the taste alone is close to making it worth it) and hearing stuff like this from people that I respect and don’t have a commercial stake in the industry are really convincing.
Vowing to take a look at primal/paleo again……
In other news, I rode yesterday. An hour at a trot. A really really really really fast trot. And she didn’t buck or try to break gait. I would prefer a slower trot –> some under 10 mph. We were going close to 15 or 16 I think……not so great for those rear suspensories or other soft tissues, so I’ve been told. I’m not totally sure how fast I was going, but we can guess based on the following facts.
1. It was much much faster than 10 mph
2. It was much much faster than her usual preferred crusing pace of 12-13 mph. In fact, it can be explained by the mathmatical formula of what 10mph feels to 12mph, 12 mph felt to this pace + 2mph (10:12 = 12:? + 2).
3. It was so fast and extended it felt like my Standardbred’s extended trot, where you can no longer post. There’s 3 beats. You kinda come out of the saddle, and then your butt has a “double bump” in the saddle.
4. My legs were shaking after I dismounted.
So…… yeah. Not the “best” thing for us, but I think it’s something we needed. She needed to be able to go without too much micromanaging, I needed to know I could trust her at speed, AND we both need to know that I can ride a bit “too” fast during a short ride and that she can take a few stumbles and her leg doesn’t blow up. I’ll be rechecking it today. Because I really need to know that the level I’m conditioning (1-2 hours at a trot) isn’t THAT close to the line. Because if an hour doing just a “little” too fast causes a change in that leg, than I need to rethink what we are doing. Because the probability of us both being perfect (me rating speed and her taking stumble or two) is about nill and I CANNOT be conditioning so close to the line that a mistake or two on a shorter conditioning ride spells disaster. All sorts of things happen at endurance rides and I don’t want to carefully bring her up to a 50 mile distance, only to find out that we were too close to the line and had a subclinical injury/damage that I never caught –> where if I do a rather rough shorter ride and there’s a hint of a problem, I can back off and rethink this whole thing. Hope this makes sense. I have a test today, a final on Friday (actually 3 of them), and an oral exam next week…..so my brain is rather fried.
Still no little “heat conditioning” veins present on Farley, her pulse was about 80 after trotting in and dismounting and immediately checking. Did this ride at 2pm while the temps were in the 80s. Pulse dropped below 60 by the time I finished rinsing her off and gave her, her post-ride mash. With LOTS of elytes in it. One Tablespoon elyte to 2 cups of pelleted feed. Still not touching her elyted water, but I’ve been able to up the elytes in her mash no problem.
BTW – a little tip that may or may not be true, but couldn’t hurt to try. After a lesson/ride/session with your horse, there may be some evidence that giving them something to munch on (hay/mash) may improve their “latent learning” –> ie how well they synthesize, retain, and make new connections about what you just taught them. The book I’m reading suggests giving a dog a chew toy/bone/kong at breaks between training sessions to help with the latent learning process, something based on observations in the horse world. No, I don’t have a scientific reference for ANY of this, so take it as an anecdote/one persons opinion if you will :).
And one more TMI for you –> I think I once again managed to jam the last joint on the middle finger of my right hand. This is only the 100th time or so I’ve managed to do this. I have drastically reduced mobility in that joint which probably makes it even MORE likely for injury. I *think* I did it dismounting yesterday but I’m not sure. It seems a bit worse this time –> it’s a different color at the tip now (greenish purple) and it’s numb so I’m thinking maybe it’s time to actually do something about this? mmm…but then I can’t type! And really it doesn’t hurt unless I try to bend it past it’s reduced ranged, or I bump the joint at the flex point on the underside of the figure. Maybe by the time I’m 50 it will be so stiff I’ll go around giving people the bird. Thank goodness you don’t finger the fiddle right handed or I would be screwed.
With all the tests coming up, you might be thinking that it’s about time for me to announce another “black out” period for new blog posts….and you would be right. As tough as it might be, I PROMISE to practice self control and NOT post until after my test on Friday. Ummm…..and completely ignore the fact that I have like 3 REALLY cool posts I’m itching to do. Including a review of Laura Crum’s new book. And the 10 commandments of endurance riding. And a Platypus water bottle review. Yes, I’ll ignore all this goodness in favor of passing this block.
