Lose 10 lbs. of Fat Tomorrow?

 Turn on your TV or your radio and it’s highly likely a “miracle” supplement is advertised. It seems as though every week, a new supplement is touted to help you lose fat or gain muscle ridiculously fast with minimum efforts. Well, I hate to break it to you, but illegal anabolic steroids are usually the only thing capable of producing rapid fat loss or quick muscle growth.

Dietary supplements are protected under The Dietary Supplement Health and Education Act (DSHEA), meaning dietary supplements do not have to demonstrate proof of effectiveness or even safety. Scary right!? Some fat burners have even been linked with inflammation of the liver. That’s not all… A product marketed as a vitamin B supplement was linked with unusual hair growth in women and impotence in men.¹ Why? Two potentially harmful anabolic steroids were found in the product.

            

            So just how can you tell if a dietary supplement is a fad? Fear no more, The Academy of Nutrition and Dietetics has provide you with 10 red flags. Now you have the ability to decide if a supplement or even a diet is credible or if it’s a fad promising to give you a fat burning and muscle building “super powers.”

            Here it goes: It promises a quick fix, there are dire warnings of danger from a single product or regimen, the claims sound too good to be true, there are simplistic conclusions drawn from a “complex” study, the recommendations are based on a single study, there are dramatic statements that are disproved by reputable scientific organizations, it lists “good” and “bad” foods, testimonials that are used to help sell the product are present, the recommendations are based on studies published without a peer review, and finally the recommendations from studies ignore differences among individuals or groups.³

Hoofta, give me a chance to catch my breath!

            The best approach to a weight loss program includes healthy food choices with exercise, behavior modifications, nutrition education and some motivation. Building muscle requires a gradual increase in energy intake with combined weight lifting to maximize muscle mass gain over fat gain. Finally focus on proper fueling with food rather than dietary supplements.

Once your food is in place, certain dietary supplements can be effective.

            Whey protein, creatine, and even caffeine have been proven to be effective in aiding your training. But before whipping out your wallet for supplements, make sure you keep the 10 red flags in the back of your mind to save your health and your wallet talk with a Registered Dietitian.

Cranberries--America's "Superfruit"

While news headlines may lead to you believe we need to travel to far-off, exotic locations to unearth nature’s “superfoods,” the reality is we can find “superfoods” right in our back yards.  Gogi, noni or acai berries are popular among health trendsetters; marketers of said foods promise a life-altering experience after consumption of those foods and often the price tag would lead you to believe that yes, this outrageously priced food must be a food cure-all! 

While I cannot vouch for the validity of such promises, I can vouch for the benefits of all-natural, versatile and affordable cranberries.  Cranberries are actually one of two native fruits of North America, the other being blueberries.  Native Americans used cranberries for their medicinal purposes and also to make an energy bar-like product called pemmicana.  While Native Americans called cranberries sassamanesh, Dutch Settlers eventually called them crane berries because the flower resembles the head and bill of a crane.¹   Nowadays, we call them cranberries and I was surprised to learn that cranberries far outrank blueberries and cherries in yield, production and consumption. ² So while we may think of cherries and blueberries as patriotic fruits, cranberries really are all-American.

Besides widespread consumption and popularity, cranberries have numerous convincing health benefits backed by research.  It’s worth noting that a pound of cranberries rings in at about $2.50 per pound while those other, exotic “superfruits” cost around $27 per pound.  So after checking out just a few of cranberries’ health benefits, below, consider keeping a bag of affordable cranberries around year-round, not just throughout the holiday season. 

Urinary tract infections: Antibacterial resistance is an increasing issue and health professionals are looking for other options in treating and preventing infections.  Cranberries have been shown to reduce the incidence of recurrent urinary tract infections (UTIs) in women and children.  Cranberry consumption prevents bacteria from adhering to cell walls in the urinary tract; if bacteria cannot adhere they won’t grow and cause infection.  Studies have tested 100% juice, juice cocktails as well as capsulated cranberry extracts and found positive results in all.  It appears that drinking a glass of cranberry juice twice a day may have the best benefits.

Cardiovascular:  Cranberries contain a unique set of proanthocyanidins (PAC), including the rare type-A PAC.   With the exception of lingonberries, no other fruit contains type-A PACs at the high level of cranberries.  It is these PACs that give cranberries their associated health benefits. ³ Cranberry consumption leads to an improvement in several cardiovascular disease risk factors, such as cholesterol, inflammation, arterial stiffness and endothelial function. 

Cholesterol—Both animal and human studies show that consumption of cranberry juice anthocyanins lowers LDL cholesterol by interfering with LDL uptake.  Additionally, cranberry anthocyanins inhibit cholesterol ester transfer protein which increases HDL concentrations. 

Inflammation—Because cardiovascular disease is an inflammatory disease, risk is often expressed in terms of levels of C-reactive protein (CRP) and other inflammatory biomarkers.  In vitro and in vivo studies have shown that cranberry juice consumption leads to decreases in CRP and vascular cell adhesion molecules in patients with hypercholesterolemia, thus lowering risk.

Arterial Stiffness—Arterial stiffness measures predict cardiovascular events and are often used as a measure of the pathogenesis of hypertension and heart failure.  Luckily for CVD patients, arterial stiffness responds to dietary interventions - and a study by Dohadwala et al. showed that drinking about two cups of a 54% cranberry juice beverage led to a decrease in aortic stiffness.  Additionally, Jennings et. al. found that higher intakes of anthocyanins and flavones are inversely associated with arterial stiffness. ⁴

Endothelial dysfunction—A healthy vascular endothelium produces many factors that maintain vasomotor tone, thrombosis, inflammation and capillary growth.  One of those, nitric oxide, plays an important role in CVD risk as it influences blood vessel dilation, platelet aggregation and anti-inflammatory markers.  Studies have shown that cranberry bioactives increase the bioavailability of NO by increasing concentrations of enzymes that promote NO production; as such, studies have shown increased endothelial dilation and improved function after consumption of cranberry juice consumption (about 2 cups).   

In addition to a reduction in specific CVD risk markers, observational studies have also shown a decreased risk of CVD with increased anthocyanin intake from cranberries.  Considering most Americans are not eating enough fruit, according to the dietary guidelines, cranberries and cranberry products would make an excellent addition to any diet while also reducing risk of disease.  While cranberry products are often sweetened, it is worth noting that cranberry juice contains less sugar (11.7g/100mL) than 100% grape, apple and orange juices (16.5, 11.1 and 10.5 g/100mL).  Additionally, dried or fresh cranberries are also prepared with added sugar but the best use of added sugar is to improve the palatability of nutrient-dense food.  Looking at the research, it is obvious that cranberries definitely are a nutrient-dense food with positive health benefits.

Don’t Let the Holidays Sabotage Your Workouts asond Waistline

The holidays are here overflowing with parties, yummy treats, alcohol, stress, and lack of time for workouts. Heavy eating and drinking during the holidays can make you feel sluggish, interfere with the intensity of your workouts, and cause you to jump on the weight loss New Year resolution bandwagon.

 

source

You could hide under a blanket in an attempt to avoid the celebrations and delicious foods.   That’s not fun.  The key is balance.  Here are some ways you can even out the playing field and emerge from the holiday season still fitting into your favorite pair of jeans:

·         Don’t show up to holiday parties hungry. If you show up to a party low on fuel, the end result is piling your party plate sky-high with fatty, salty, albeit delicious foods. And you may go back for seconds. Before heading out to a party, have a small snack that will quiet a grumbling belly. For example, try a ¼ cup of trail mix, 2 teaspoons peanut butter on a slice of bread, or a ¼-1/2 cup low fat whipped cottage cheese mixed with 1 teaspoon jam.

·         Hydrate. The abundance of alcohol can dehydrate you. While it’s great to kick back and relax a bit, going overboard can lead to dehydration, greatly impacting your damage-control workout the day after. Be sure to stay well-hydrated throughout the day, and drink water in between your holiday glasses of wine.

·         Load up on healthy stuff.  While at a holiday party, survey the choices. Is there a green salad? Roasted veggies? Sushi platter (not ‘tempura’, aka, fried)? A platter of grapes or fruit salad? Try to load your plate up with the healthiest choices, and save a small portion of your plate for the savory, rich foods.

·         Find a goal to keep motivated.  Keep unwanted pounds away by signing up for a holiday run in your neighborhood. Many towns sponsor a “Ho, Ho, Ho” or “Jingle” run. Check out a website like www.active.com to find out what races are near you. Is your gym holding a holiday challenge? Sign up! This time of year many gyms also start to offer discounts on personal training packages. 

·         Something is better than nothing. We are so busy this time of year, it can be too easy to ditch your workout.  Search through workout magazines and websites for short, yet effective workouts you can squeeze into a 30 minute window.  Many workout DVDs are focused on short, intense workouts lasting 20-30 minutes. The Runner’s World website posted the article “Three Workouts to Maintain Fitness Through the Holidays” featuring short duration, high intensity interval training workouts on the treadmill that may boost post-workout metabolism and possibly help improve speed.  Whatever workout you choose, 30 minutes is always better than nothing!

Should the holidays get the best of you and leave you feeling defeated, remember, you do not need to give up. Pick yourself back up again, find a race or gym challenge that motivates you, urge friends to join you, and get back into the swing of your workouts and healthy eating. Happy Holidays!

Can Walnuts Increase Improve Your Exercise Performance?

                Regular walnut consumption is associated with several health benefits including healthy brain aging, improved cognitive performance and heart health. (1, 2, 3)  But, in case that’s not convincing enough to make you want to add a handful of walnuts to your diet daily, I have another reason. Walnuts may even the ability to improve exercise performance!

source

                Researchers of a study published in the Journal of Laboratory Animal Research, investigated the anti-fatigue effect of walnuts on the forced swimming capacity in mice. (4) A forced swimming test is essentially like dropping you into a water tank where you cannot stand or hold onto something. This type of test acts as both an endurance and a stress test. The mice in the experimental group were given either 300, 600, or 900 mg/kg a day of walnut extract, while the mice in the control group were only given water.  It turns out that the mice who were given walnut extract coped much better than mice in the vehicle control group.

                The increased swimming times by the mice given walnut extract are suggested to be in part due to decreased levels of lactate and ammonia. The accumulation of blood lactate and ammonia are known to cause fatigue and decreased exercise capacity. Therefore, it is suggested that the walnut extract exhibits an anti-fatigue effect. And, while all dosages of walnut extract resulted in increased endurance, 600 mg/kg appears to be the optimal dosage. The walnut extract dosage of 600 mg/kg a day was based on human equivalent of the recommended intake of raw walnut – which is about 42 grams per day, or roughly about a handful.

                Walnuts complement a wide range of flavors and they are great to add to just about anything. Try adding walnuts to your morning cereal, toss some in with your salad, sprinkle them on pasta, or even use them to make delicious dips and spreads!

Beet Recipes: Red Velvet Smoothie and Roasted Beets

Tis' the season!  We learned from Kym's last post of the benefits of beets and exercise.  These two recipes show us how to incorporate more of this seasonal color into our diets.  

Red Velvet Smoothie                                               Serves 1

All you need:

¾ cup 1% milk

½ cup roasted beet cubes (about 1 - 2 whole beets)

3 pitted Medjool dates

2 tablespoons cocoa powder

½ teaspoon vanilla extract

1 scoop chocolate or vanilla whey protein powder

½ teaspoon Truvia

¼ cup instant oats

¾ cup ice cubes

1 tablespoon dried cherries

All you do:

1.      In a blender pitcher, combine milk, beets, dates, cocoa powder, vanilla extract, whey protein powder, Truvia and oats. Blend until smooth, about 2 minutes. 

2.      Add ice cubes and cherries; blend again to reach desired consistency (1-½ to 2 minutes for a smooth texture).

3.      Pour into a serving glass and serve.

Roasted Beets                                                                                    Serves four

Use roasted beets in the smoothie recipe, above, without olive oil, salt and pepper or serve these roasted beets over a baby spinach or arugula salad. Use a simple vinaigrette made with fresh orange juice, orange zest, olive oil and Dijon mustard.  Top with fresh goat cheese, pistachios or sunflower seeds, leftover roasted chicken and thinly sliced fennel.

All you need:

4 medium beets (about 1 pound without greens)

2 tablespoons extra-virgin olive oil

Salt and ground black pepper

All you do:

1. Adjust an oven rack to the middle position and heat the oven to 400 degrees.  Trim all but about 1 inch of the stems from the beets.  Wash the beets well and remove any dangling roots.  Wrap the beets individually in aluminum foil and place the wrapped beets in a shallow roasting pan or a rimmed baking sheet.  Roast until a skewer inserted into a beet comes out easily, 45 minutes to 1 hour.
2. Remove the beets from the oven and carefully open the foil packet (make sure to keep your hands and face away from the steam).  When the beets are cool enough to handle, carefully peel off skins.  Slice the beets ¼ inch thick.  Toss the beets, oil, and salt and pepper to taste together in a medium bowl.  Serve warm or at room temperature.

The Dirt on Beets: Improving Athletic Performance, One Sip at A Time

Love ‘em or hate ‘em, beets are proving to be one food you may want to consider adding to your training repertoire.  As fellow SCAN blogger Gavin Van De Walle wrote, beets have the potential to improve athletic performance and cardiovascular health, thanks to their high nitrate content.  Through a series of reactions, the body converts nitrates to nitric oxide; nitric oxide, essential to body function, has several beneficial effects, including blood vessel dilation, lower resting blood pressure and increased blood flow to tissues throughout the body.  Recent evidence indicates that supplementing the diet with inorganic nitrates lowers the oxygen cost of exercise, making muscles more efficient, and may enhance athletic performance by increasing time to exhaustion, power output and exercise tolerance. ¹ 

The synthesis of nitric oxide occurs at the time of low oxygen, low pH and intense physical activity, Nitrate consumption is especially beneficial for short (5-30 minutes) bouts of intense, aerobic physical activity, such as running, sprinting or rowing. ^{2, 3}  Researchers are starting to discover that nitrates may also be helpful for team sports, where repeated bouts of high-power, high-intensity energy are required (such as football or volleyball).⁴

Beets and beet juice have been researched most extensively at doses equivalent to approximately 1-½ cups roasted beets or 500mL of beet juice, providing approximately 500mg of nitrates. Other high-nitrate foods include spinach, escarole, lettuce, celery and arugula; it’s likely these other foods would also prove beneficial.  Considering that “whole foods” also contain fiber, antioxidants and other nutrients that have beneficial health effects, opting for whole beets instead of beet juice would be beneficial. 

If you don’t care for beets or beet juice, there is the option of Beet Elite.  Using a low-temperature dehydrating process, the folks at Beet Elite create a powdery substance made from organically grown beets.  Though the company’s patented technology, the nitrate-nitric oxide conversion occurs more quickly, allowing you to consume the drink just 30 minutes prior to your workout (rather than two to three hours).  Mix the crystals with ½ cup of water and voila!  Your pre-workout beverage is served.  Each serving is the equivalent of six beets. The smaller serving size (1/2 cup liquid vs. 2 cups of juice) is also appealing.  Unless you enjoy eating beets, daily, before your workouts, you may want to consider this route.

I was skeptical of all these promises but after using Beet Elite before my “short but intense” rides for my most recent century ride training, I can attest that my workouts felt easier and I was able to ride stronger than when I did not use it.(Not exactly a high-quality scientific experiment, but perhaps helpful, nonetheless).  How does it taste?  Definitely a little, ahem, “earthy.” It definitely tastes of beets but black cherry-flavored Beet Elite is definitely palatable and something one can tolerate for the added performance benefits.

There are a few caveats to using nitrates as an ergogenic aid, however.  First, the nitrate-nitric oxide cascade begins in your mouth by salivary bacteria; use mouthwash containing alcohol and you kill off those good bugs and prevent the reaction from occurring.  Second, nitric oxide in blood peaks two to three hours after nitrate consumption; if opting for whole beets or other nitrate-rich foods, meal planning is essential.  Third, a daily dose of nitrates (or Beet Elite) is required to keep plasma nitrate levels elevated.  Finally, most studies have tested activity that is short in duration (30 minutes); for longer bouts of activity, the research is still out but folks at Beet Elite recommend a second dose (after four hours, not exceeding two doses in 24 hours) for longer endurance events.

Tis the Season: Table Scrap Safety for Dogs

The holidays are a time of gathering while fighting weight gain.  Those of us who are “dog parents” are more likely to exercise and meet the federal criteria for regular exercise.

As we are approaching that time of year, our homes welcome in visitors or we are guests at someone else’s home.  By the time you sit down, you may be welcomed by an eager canine who wants a treat.

The American Society for the Prevention of Cruelty to Animals (ASPCA) has holiday recommendations that you and your guests should heed when it comes to Fido’s safety.

The Society recommends avoiding the following:

Chocolate—may cause vomiting, fever, seizures, abdominal pain, and possibly death.

Grapes and raisins—are associated with kidney failure with some dog breeds.

Macadamia Nuts—can cause tremors, weakness, and fever.

Onions, garlic, shallots, and scallions—these aromatics can damage red blood cells.

Raw bread dough or raw cake batter—will cause pain and bloating to the animal and may require surgery.

  

Regarding cake batter, dogs can become sick from salmonella.

Turkey—a few small boneless pieces of cooked turkey, may not cause a problem but don’t allow your dog to eat too much as it can cause Pancreatitis.

Try your best to keep your dog (and maybe yourself too) on a normal diet during the holidays.  If you’re feeling guilty, consider giving your pet a new chew toy or take them for an extra-long walk to tire them out before guests arrive.  When in doubt, don’t feed dogs table scraps.  If your new four legged friend is guilt tripping you, ask the host for a dog approved treat to give.

Protein Consumption, Physical Activity, and Obesity: A New Study Reports the Role of Combining All Three

A recent study published in the Journal of Applied Physiology examines the role of combining whey protein, resistance training, and insulin resistance (HOMA-IR) in obese individuals.  The study looked at the role of timed-ingestion of supplemental protein (20 g servings, 3 times per day) added to the diet of overweight/obese adults.  They were randomized to receive whey protein, protein and resistance training, or whey protein and a multi-mode exercise program (PRISE, Protein, Resistance, Interval Training, Stretching, Endurance training). 

Body composition, visceral adipose tissue, lipids, adipokines* and insulin sensitivity were examined.

The researchers examined obese individuals over a 16 week period.  Results are as follows:

·         The PRISE exercisers lost the greatest amount of body weight 2.6% versus the protein and resistance training group and fat mass, 6.6% versus the protein/resistance training group. 

·         There was a 14% decrease in fasting glucose along with improvements in insulin sensitivity (HOMA-IR).

Researchers found “evidence to support exercise training and timed-ingestion of whey protein added to the habitual diet of free-living overweight/obese adults, independent of caloric restriction, on total and regional body fat distribution, insulin resistance, and adipokines” (Arciero, et al, 2014). 

*Adipokines (or adipocytokines) are cytokines (cells that signal proteins) that are secreted by adipose tissue; some research suggests they can also be added to adipose-derived hormones.

10 Reasons You Should Start Blogging

Marathon Season: Recovery 101

You just ran a marathon. Congratulations! Now it’s time to focus on recovery. Nutrition plays a key role in mending your marathon-weary body and getting you back into running and other activities sooner rather than later.

Post-race nutrition should focus on replenishing glycogen stores, rehydrating, and muscle repair. In conjunction with proper sleep and easing back into running, proper nutrition is a vital piece of the recovery puzzle.

 

Source: Mlive.com

Directly after the marathon

As soon as you finish, you will feel exhausted and may not have much of an appetite. Every runner tolerates different foods or drinks after the marathon. Within 30-60 minutes following your 26.2, focus on a combination of protein and carbohydrate, whether it be in the form of a drink or food.  Aim for approximately 200-400 calories of carbohydrate along with 10 grams of protein for this immediate post-marathon snack.[i] Remember to eat or drink slowly to give your gut time to adjust. Ideas include:

*Chocolate milk may be a welcome change after downing fruit-flavored sports drinks during the race.  It’s a cheaper post-workout option vs. recovery drinks sold in health or drug stores. 

* Greek yogurt with granola or cereal mixed in.

*A bagel topped with cheese, whipped cottage cheese, or peanut butter and jam.

*My personal favorite: 1 large egg cooked in a pan, 1 slice cheese, and mixed greens on a whole grain roll or English muffin plus one serving pita chips.

Days following 26.2

The recovery period following your marathon is just as crucial as your eating during training. Here is a list of great foods to jump start your eating routine in the days following your marathon.

*Tart cherry juice, loaded with anthocyanins, may be a great recovery booster.  Some studies have linked drinking tart cherry juice with reduced inflammation following a marathon and other forms of exercise. [ii], [iii]   Try adding tart cherry juice to a blended juice drink or drink it straight.

*Apples have quercetin concentrated in their skins, which is shown to have anti-inflammatory properties.[iv]  Try apple slices with peanut butter, or chop apple into your oatmeal and cook with low-fat milk for a carbohydrate and protein boost.

* Healthy fats (mono- and polyunsaturated fats) such as grilled salmon for dinner, sliced avocado on a sandwich, or sprinkle mixed nuts in cold cereal or oatmeal.

*Pumpkin, acorn and butternut squash not only provide a great source of fiber and vitamin A, but also potassium,  an electrolyte that is depleted along with sodium during your marathon.4 Instead of mashed potatoes, try mashed squash. Bake cubes of butternut squash, add some milk, 1-2 teaspoons of butter, salt and pepper to taste, then puree in a food processor or mash with a handheld masher for a rough texture.

Remember that hydration is the number one priority in the hours and days following your marathon. So don’t just eat up, but drink up!

Weight Loss as Preventative Medicine

We as Registered Dietitian-Nutritionists understand the importance of healthy weight.  At times the medical community feels uncomfortable with addressing obesity.  The Mayo Clinic's Nutrition Wise blog cited the Strategies to Overcome and Prevent (STOP) Alliance for Obesity.  

They found that nearly 90% of doctors feel it is their responsibility to help their patients lose weight.

Unfortunately, 72% feel that no one in their practice has been trained to deal with obesity.

When surveying obese patients, only 39% of obese adults were ever told by a doctor or health care professional that they were obese.  

90% were told to lose weight but weren't given any instruction on how to go about it. 

We as health professionals frequently neglect weight as a foundation for health.  Cancer, heart disease, respiratory illnesses are just a few conditions that are all exacerbated by excess weight. 

New research from the Mayo Clinic demonstrates the importance of weight loss in managing cardiovascular disease.  

In a recent article, Pack, et al. did a "systematic review and meta-analysis of the prognostic effects of weight loss in patients with Cardiovascular Disease (CAD)."  Studies taken into consideration covered 49 years of research from 1964 to 2013.  

The research team reviewed 1218 abstracts for a total of 35,335 patients with an average age of 64 years.  

Intentional weight loss in subjects is associated with lower clinical events.    

We just got through October and breast cancer awareness but how many times did you see people discuss weight?  Early detection is critical with breast cancer but what have we looked at regarding possible prevention?  

The Journal of Cancer Research, recently published: "Weight loss prevents obesity-associated basal-like breast cancer progression: Role of hepatocyte growth factor/c-Met."  That sounds complicated but researchers concluded that weight loss reversed "obesity-driven tumor aggressiveness promotion and blunted the obesity-responsive" tumor growth pathway while improving multiple metabolic and inflammatory risk factors. 

These are just three recent articles on the effects of weight and illness.  To learn more about talking about obesity visit: http://www.stopobesityalliance.org/.

Pasta Alternatives for Pre-Endurance Fueling

During marathon season, fellow runners ask what they should eat the night before to fuel a long training run.  Most runners automatically assume the answer is pasta. While pasta is a great choice, it can cause gastrointestinal troubles for some, and it can simply get old and boring for others.

Runners with Celiac disease simply cannot eat a wheat-based pasta (regular pasta made with wheat contains gluten, a wheat protein that triggers digestive problems in Celiac disease patients).  Runners suffering from non-Celiac gluten sensitivity also may find pasta to be a poor pre-race choice.  Runners in neither of these categories simply may be eating too much pasta, or choosing a sauce that may cause gastrointestinal issues.  Cream sauces (think penne a la vodka) are heavy in fat and digest slowly, which can cause race day stomach issues. A simple marinara sauce, while having little or no fat,  may be too acidic and cause acid reflux.

Training season is the best time to test-drive your pre-race meal vs. trying something new the night before race day. Why not try some of these carbohydrate-rich alternatives to pasta the night before a long run:

·         White rice:  Cook up a bowl of white rice, toss with vegetables, and a tablespoon of teriyaki or soy sauce for flavor. Or, eat rice as a side dish with a lean protein like chicken or fish.

·         Sweet potato: Cut sweet potato into pieces, cut up an apple, grab some golden raisins, toss them all together in a light drizzle of olive oil, season with paprika and garlic powder, and bake.

·         Breakfast for dinner: What about a batch of blueberry pancakes? Cut back on sugar and use a small spread of jam on the pancakes with some peanut butter vs. traditional pancake syrup.  Even a bagel with jam and peanut butter for those lazy, no-cook nights.

·         Rice-based pasta: For those with Celiac disease or a gluten sensitivity, cook up a rice-based (gluten-free) pasta. As with regular pasta, be careful of your sauce choice. Try tossing it in olive oil, garlic powder, and parmesan cheese. Or try a balsamic glaze with veggies mixed in.

·         Healthy pizza: Buy a pre-made thick pizza crust (thick crust = more carbs). Use a thin layer of pizza sauce, and approximately ½-3/4 cup (depending on size of crust) of a low-fat shredded mozzarella. Sprinkle whatever toppings you crave: black olives, broccoli, slices of turkey pepperoni, mushrooms, or chopped grilled chicken.  You may omit cheese and use only veggies and pizza sauce.

Race training is not just for logging miles, but for testing out what makes your gut happy. A big bowl of rice and veggies may be just what you need to power you through your long run, while another runner may feel best eating a large baked sweet potato and baked breaded chicken. Fine tune your pre-race fueling during training months and never try something new the night before or morning of a race.

Feast on Beets!

Picture Source  

It’s no secret that vegetables are good for us. But the humble beet may have a little extra to offer. Beets are high in inorganic nitrates which may exert an ergogenic – or performance enhancing – effect. In fact, consuming beetroot juice may have the ability to improve running performance and reduce the oxygen costs of exercise.¹

A study published in the Journal of the Academy of Nutrition and Dietetics looked at whether eating 200 grams of whole beetroot, which is about 500 mg of nitrates, prior to exercise would improve running performance during a treadmill time trial.² The study used a double-blind crossover design in which subjects ate either baked beets or a placebo consisting of cranberry relish 75 minutes prior to completing a 5 kilometer treadmill time trail test. It turns out that those who consumed the baked beets significantly improved their running times by three percent. While this difference may not seem like much, a three percent faster time translates to a 41 second faster finishing time. This increase in performance is most likely due to the conversion of nitrate to nitrite and finally to nitric oxide in the body.

So how does dietary nitrate get converted to nitric oxide?

The breakdown and use of dietary nitrates actually begins in your mouth. The bacteria on your tongue help reduce about a quarter of the dietary nitrate from foods – such as beets – to nitrite which is then swallowed and reduced to nitric oxide when it mixes with the acid in your stomach. Nitric oxide regulates vasodilation, relaxing blood vessels and increasing blood flow, which reduces the oxygen cost of exercise. This means, your muscles can use less energy to produce the same amount of work.³

From a practical standpoint, this study indicates that consuming 200 g of beetroot, or two medium sized beets – equating to approximately 500 mg of nitrates – an hour or two before exercise could improve your running performance. Different methods of cooking techniques – such as baking or pureeing – do not appear to reduce the nitrate content. Therefore, don’t be afraid to get creative even though drinking beet root juice may be more palatable. Try smoothies, bake them into chips, or try other recipes from the web!
