Beet this.

There are lots and lots of ergogenic aids out there which tout the ability to help enhance your athletic performance. Anjee what is an ergogenic aid?! you ask. It's basically anything that has the ability to increase your capacity for physical performance. This can be caffeine or steroids.

An article in the Summer edition of Food and Nutrition magazine had an interesting blurb about beetroot juice and its benefits for middle distance and endurance athletes.

Seems there is some research out there that indicated beetroot juice may delay time to exhaustion. Yep. Looks like our beety friends are rich in nitrate which has two effects on the body during exercise:

  1. It reduces VO2max which is means it reduces the demand for oxygen during exercise. Obviously the lower the demand for O2 the more efficiently (and longer) you are able to place demands on the body before exhaustion. 
  2. Increases muscle efficiency. Muscles are able to utilize O2 more efficiently thus delaying the time to fatigue. 
The acceptable daily intake of nitrate is 3.65 mg/kg/d and the amounts used in the studies are usually about twice this amount so it remains to be seen how safe it is to supplement with beetroot juice but interesting stuff nonetheless. 

Would you drink beet juice to increase your performance? I may have to try it on my next long run......

Remember me?


Hello there.

You may or may not have noticed I've been out for a bit. Well, I'm back.

Let's see. Let me just sum up the last few months here. I finished my thesis, defended my thesis much to the chagrin of my PI, faculty, staff and students of SDSU. FINALLY took surfing lessons much to the chagrin of all involved. I am no longer terrified of the ocean. That's a lie. Celebrated my 34th birthday. Oscar and I broke up. I moved out. Was placed in a dietetic internship which I start in July. I have joined a climbing group. I only go because we go out for beers at Smallbar after every Wednesday. I deleted my face book (no I didn't defriend you I just am over FB right now). And I think that about does it. Oh and I graduated last Friday.

So now that we have that out of the way, let's get updated on the nutrition world, because really, isn't that the more exciting thing here?



The American Dietetic Association is now the Academy of Nutrition and Dietetics. I am not sure why although I assume it's because they feel it sounds fancy to call themselves the Academy of Nutrition and Dietetics. I'm not sure they thought this one through however because the acronym is going to be AND. Doesn't sound fancy when you see it like that does it? Anyway, that is the new institution and that is how they will be addressed. I have been paying extra special attention to AND lately and it's position on the new health care laws; it has been very interesting watching how this whole health care reform business plays out in regards to nutrition professionals. Many of the billing codes are going to be changed to limit certain nutrition related therapies or remove them all together. Obviously this is a concern moving forward and has a lot of us wondering what exactly our careers will look like in the future. Time will tell I suppose.

But onto a little blurb from my Food and Nutrition magazine. This month had an article on juicing and I thought I'd pay it a little mind since everyone from my new roommates to my brother are juicing these days and it's something I get asked about quite a bit.

Juicing is the process of using a juicer to separate fruits and vegetables from their peels, pulp,fibrous materials, etc., into a purely liquid form. It's different than blending since the juicing process actually removes the other components of fruits and vegetable whereas blending them uses the entire fruit and/or vegetable. 

Juicing has also been getting a ton of attention lately. Many hail it THE a way to lose weight and others insist it is the best way to consume fruits and vegetables. Movies, movie stars and fitness advocates alike seem to be hopping on the latest industry trend. 

In an attempt to figure out what the fuss was about, I made a few juices of my own. Tasty, diarrhea looking things from kale, ginger, lemon, parsley and carrots. I juiced a whole bag of oranges one time and got two whole glasses of juice out of it. After a particularly rigorous week of post break up drinking I juiced for what was supposed to be ten days but was chiseled down to six after I just about got fired from my job for being so darned cranky from being so darned hungry. Don't get me wrong, my juices were tasty!! Seriously they were so good. And I actually felt pretty good too after drinking them. I didn't get the fit of hypoglycemia I assumed would follow a strict juicing diet. My main concern wasn't what was in the juice, but what wasn't in it.

After I reduced a weeks worth of produce to a glass of liquid, all the fibrous material (the stuff that contains almost ALL the fiber) was still in my juicer. One time I tried adding it back into the juice but to be honest it was pretty gross, but I digress.

I think this article from Food and Nutrition Magazine gives great tips on how to be a smart juicer and hopefully get the most benefits from juicing. A few main points:
1) There is no advantage to consuming juice over whole fruits and veggies
2) Juice-only diets which severely restrict calories may result in short term weight loss (and later to weight gain) but the lack of protein won't sustain muscle mass
3) Other deficiencies like fiber, fat soluble vitamins D and E, essential fatty acids and B vitamins may result
4) Always thoroughly wash fruits and veggies and consume juice immediately
5) Aim for a 3-to-1 vegetable to fruit ratio

And it's important to remember juicing really shouldn't be replacing meals and its hold no benefit over consuming fruits and vegetables in their raw, whole form but can be a great way to incorporate fruits and vegetables into your diet if you have a hard time doing so


Do you juice? If so what's your favorite recipe?
