Meera: -   Carbohydrates are the key nutrient during a Race. But what’s the ranking of other nutrients?  Plus, could the diet be controlled as a preventative measure to protect our bodies as well? Meera caught up with team nutritionists Mark Quod and Matt Rabin in the riders' area before stage 10 of the tour.  And Mark began by explaining the ranking of nutrients after the crucial carbohydrates...

Mark: -   After the race, protein; they’re out there on the bike for so long, you’re going to  get some muscle degradation so to maintain protein balance throughout the 3-week race, those proteins are very important.  And of course, fats are important for various other body functions as well, so that’s the general order.

Meera: -   And what about the timings of when they should eat?  So now, this is stage 10.  The race is in about an hour.  What have they eaten this morning and is there meant to be a certain gap? " alt="Pasta and Pesto" />

Mark: -   Yeah, the guys have a protocol of when they eat in the morning.  First, they get up and have some breakfast then an hour or so later to have a race meal with rice and pasta and things like that.  Now, just an hour before the race, they also have liquid meals that have carbohydrates, proteins, and fat in certain quantities, so they're well and truly loaded, and ready to go for the race.

Meera: -   Now moving over to you Matt, the cyclists here are on a non-gluten diet, so gluten-free.  Why is that important?

Matt: -   We implemented that in around 2008, just because we looked at foods which are more difficult to digest, more difficult to assimilate.  We noticed that some people had an issue with gluten.  Since we’ve implemented it, we found that guys don't get so bloated when they eat certain foods, so that typically means leaving bread for example out of the diet, but we have also removed many other sorts of simple foods which typically can cause irritation and are harder to digest.

Meera: -   Such as?

Matt: -   Such as dairy for example.  So, we gave a plan to our chef at the start of the Milktour, and he knows exactly what our protocols are as related to foods that we want to try and eliminate, and the foods we want to try to replace them with.

Meera: -   And you also deal with, say, recovery foods.  So you know, cyclists, they're greatly using their muscles, they're obviously exhausted after races.  So, what’s the road to recovery diet wise?

Matt: -   These days in cycling, you got 16 hours say, from when they get on the bike to when they got on the bike the next day.  With that in mind, we sort of looked at the guys’ simple blood values and things that some of the riders might have intolerances with or allergies against, so we just try and remove those from the diet.  That allows the body to assimilate and digest a lot better without irritation and allow them sort of recover better ultimately.

Meera: -   Inflammation is the key thing, isn’t it?

Matt: -   The foods that we sort of try and promote if you like are of an anti-inflammatory nature.  Cellular inflamation is going to affect everything that a rider does because the body is under stress all day, 4, 5, 6 hours a day on the bike, that is going to create inflarmation.  So, anything we can do to sort of stop that in between stages are going to be of benefit for their performance.  So the less inflamation you have and the more we can get that under control, the better they're going to perform.

Meera: -   How would you even go out testing this?  How would you know who’s more inflamed than others?

Matt: -   Every quarter, we measure some simple blood parameters such as the arachidonic acids in the blood and the ecopentaenoic acid in the blood, so that’s AA and EPA in the blood.  And we look at these ratios to tell us how inflamed their bodies are at any given time.  From that, we can modify their diet and give them the instructions to modify their diet.  So the guys that have been on the team for 2 or 3 years, I mean, they're familiar with these tests, what they mean and how to implement them in order toCyclist sign get the best recovery.

Meera: -   And just lastly then I guess.  If there was one key tip when it comes to diet, what should be remembered by cyclists?

Matt: -   For me, I would say that the recovery is a massive aspect and so, carbs are king during racing, but it’s getting the protein in post stage is really, really important.  So, on the bike; carbohydrates, recovery; think protein.

Meera: -   Nutritionists, Matt Rabin and before that, Mark Quod from team Garmin-Transitions.

That sounds very complicated. What can we take from it for our modern complicated and stressful lives? Consider the Inca post runners. What did they fuel up with for running through the Andes?

Here is the wikipedia discussion of Quinoa's nutritional features, "Quinoa was of great nutritional importance in pre-Columbian Andean civilizations, being secondary only to the potato, and was followed in importance by maize. In contemporary times, this crop has become highly appreciated for its nutritional value, as its protein content is very high (12%–18%). Unlike wheat or rice (which are low in lysine), quinoa contains a balanced set of essential amino acids for humans, making it an unusually complete protein source among plant foods. It is a good source of dietary fiber and phosphorus and is high in magnesium and iron. Quinoa is gluten-free and considered easy to digest. Because of all these characteristics, quinoa is being considered a possible crop in NASA's Controlled Ecological Life Support System for long-duration manned spaceflights.

So high quality protein, gluten free, and cheap..and simple to fix!

In a wok, Saute some shallots until they are limp. Bring 2 ups of chicken broth to a boil and add 1 cup of pre-washed Quinoa grain. Stir, reduce heat to low and simmer covered for 20 minutes. Turn off the heat and go talk to your girl friend for about 20 minutes. Then fluff with a fork and serve it up.

Very filling and relatively cheap. I feel ready for my 12 hour shift on the space station. MartinTheK, Thu, 12th Aug 2010

Great program--the single theme works well for TNS. I was hoping the interviewer would ask what foods are considered "anti-inflammatory." Joyce, Tue, 17th Aug 2010

I agree that Meera did a great show, but that should remain an exception as we are missing all the latest news and what if you have no interest in cycling? No, the show is best with say a main topic but with lots of other news items and oddball topics. John Muir, Sat, 21st Aug 2010
