BEET IT OR BEAT IT

Patrick Martin

Beets: Hell YA! Or ewwww….?!

Some of us love these vibrantly colored roots and some of us despise them… If you like them, you’re in luck, and if you don’t, you better learn to.

Science has been showing that they have some unique health and performance benefits. Regular consumption of beets can have some impressive effects such as reduced body fat, improved recovery from exercise, improved stamina, and improved strength. Asides from all that magic, beets are very nutritious, so even if all the science is wrong with regards to beets’ ability to turn you into Popeye, you won’t be wasting your time eating them, as they are a good source of nutrients, fibers and anti-oxidants.

PHYTO-PERFORMANCE LOVES SCIENCE

At Phyto-Performance Nutrition, we are always investigating the available scientific research on performance enhancing foods that can help us get results for our athletes and weekend warriors. As the science of nutrition evolves, we are slowly deciphering and uncovering some of the amazing benefits that foods can elicit.

BEETS MAKE ME RUN FAST

Beets have been a hot topic lately, as they’ve been shown to enhance performance in a few different ways. Initially they were found to improve aerobic capacity in terms of VO2. Improving your VO2 means that your body will need to consume less oxygen for them same amount of work, so if you run 5 km and decide to eat some beets for breakfast, your body will need less oxygen during that run compared to if didn’t consume any beets at all. This can lead to a faster run, if that is the goal, otherwise it would just lead to a more metabolically efficient run.  This effect of improved metabolic efficiency is believed to be due to their ability to increase blood nitric oxide (NO) levels, which can dilate blood vessels and allow more blood to flow in and out of muscles, and thus result in better nutrient delivery and gas exchange (Dominguez et al. 2017).

DO YOU EVEN RECOVER BRO?

Another angle in which tasty little beets can help you is by improving muscle recovery. These two recent studies by Clifford et al. 2016, 2017 investigate beet juice’s ability to improve markers of exercise induced muscle damage. Its common to feel soreness after a bout of exercise because whenever you push through your comfort threshold, you are subject to muscle fiber breakdown and the associated muscle soreness. This muscle soreness can last for up to 72 hours post exercise, and it will reduce your ability to perform. During the sore period you will have decreased strength and power output, and thus decreased performance.  What Clifford and friends measured was whether beets could reduce exercised induced muscle pain as well as recovery of strength and power, and It turns out they do!        

THE BEAST THAT IS BETAINE

Betaine and betalaines are two nitrogenous based compounds that are thought to be responsible for many of the performance benefits derived from beets. Betaine is regularly used as a performance enhancer supplement, whether in your pre-workout or taken individually. The compound betaine was originally identified in beets, hence the name, but it turns out there is a few other great food sources: Spinach, wheat germ & quinoa. Betaine by itself has the potential effect of improving strength, increasing circulating blood levels GH, and reducing body fat (Cholewa et al. 2014). Although beets are a source of betaine, most of the studies testing betaine show benefits with doses much higher than you would get from eating beets. Therefore, if your looking for performance results specific to betaine, we recommend consuming all 4 natural sources of betaine, and potentially even use a supplement. I use Rivalus powder burn which contains 500 mg, and I also purchased a pack of pure betaine from www.canadianprotein.ca

COST TO BENEFIT RATIO

That said, even though there is good science to back up the use of beets and betaine for performance, it is always a question of price-to-benefit ratio when it comes to taking a new supplement, and with beets, we also must consider the enjoyability factor – big issue for my wife, not at all for me... In my opinion, beets offer great value!

From a basic nutrition standpoint, aside from all the performance benefits, beets are a significant source of the following compounds: Folate, Mangnese, copper, fiber, potassium, phosphorus, magnesium, vit C, Iron, Vit B6. Beets are relatively cheap to buy – I recently bought a double pack of pickled shredded beets at Costco for about 5$. These were great as they were an easy addition to my lunch wraps, or as a side with my meal. I also will often add beet powder to my daily smoothies to boost my consumption, as I can’t eat beets every day.  This has the added effect of making my smoothies a nicer colour – again palatability! The beet root powder is affordable, a bottle comes to about 16$+ tx (Phyto athlete discount), contains 2kg of dried beets and it lasts me for a couple of months. When it comes to betaine specifically, I try to get as much as possible from food.  I try to consume baby spinach daily, whether in a smoothie, in my egg omelet or in a salad. Baby spinach is a super functional, easy throw-in, as well being very affordable (Costco sells are large pack for about $3). Also, I try to eat quinoa and whole grain bread or wraps WITH the wheat germ (Note: I am not gluten intolerant, my genetic test backs this up). I often make beet wraps: Shredded beets, spinach, whole grain wrap including the germ, some shredded chicken and maybe some hummus or avocado. <—- Balanced and great for performance.

SHUT UP AND TRAIN, but eat your beets too

SO, if your looking for ways to improve your health and performance, beets are a great addition to your tool box. Beets by themselves have the ability to improve your metabolic efficiency in terms of VO2. They are also nutrient, fiber, and anti-oxidant dense, and pack unique abilities to help your recovery from exercise. They contain the compound betaine, and if you want to increase muscle & strength, try getting in supplemental betaine from quinoa, spinach, wheat germ, a synthetic supplement can help as well.

 

Happy training & thanks for reading!
