The ads suggest coconut water is the perfect sports drink. What do ya' think?
Coconut water is marketed as being “100% pure” and “all natural.” Almost true. It has only two ingredients: coconut water (the watery liquid inside a green coconut) -- but also quite a bit of vitamin C that has been added to the drink. Not "all natural."
Coconut water is naturally rich in potassium (good) but has a high price tag (about $3 for a 17-ounce carton; bad).
Here’s how it compares (in portions commonly consumed by thirsty athletes) to Gatorade and orange juice:
Because serious athletes have a higher need for sodium than potassium during sweaty exercise (and you will simply flush the excess vitamin C down the toilet), I’d suggest you choose a higher-sodium sports drink during endurance workouts and spend your money on orange juice and other natural foods afterwards. That is, unless you happen to prefer the taste and digestibility of coconut water, which research suggests is not always the case (1)

Q. Help! What’s the solution to intestinal problems during long runs?
A. Upset stomachs, nausea, cramping, and urgency to take a pit stop are common problems among long distance runners. Because each person has his or her personal response to long runs, I can only ask you lots of questions, but perhaps they will help you find an answer. Here goes...
• Are you running too far, too fast too soon and your body is telling you it isn’t ready for that distance?
• Are you stressed and anxious on long-run days, and your nerves are creating the problem?
• Do you eat too much food the night before? If so, try having your big meal at brunch the day before and eat lighter at night.
• Do you eat too much breakfast before the long run? Try eating part of the breakfast the night before, at bedtime, so you’ll be less hungry in the morning.
• Do you eat fatty, heavy foods (like a sausage, egg ‘n cheese biscuit) before the long run?
• Do you drink too much pre-run coffee?
• What do you use for fuel during the long runs? Gels sometimes cause GI problems. So can commercial sports drinks or candies with the wrong kind of sugar for your gut.
• Are you chewing sugarless gum? The sweetener (sorbitol) can cause GI distress such as gas and diarrhea.
• Do you eat yogurt, kefir, or take probiotics? They can help resolve bowel issues.
• Do you get dehydrated? Lack of fluids contributes to diarrhea.
• Do you eat a high fiber diet? “Healthy” diets with abundant whole grains, fruits and veggies can become problematic for some runners.
• Is the problem limited to during runs or do you have intestinal issues at other times of the day? Perhaps you have latent Irritable Bowel Syndrome that gets aggravated during long runs?
• Do other people in your family have intestinal issues, like constipation, diarrhea, bloating, or colon cancer? Perhaps you have problems digesting gluten (a genetic tendency) and should be tested to see if you have Celiac Disease?
• Have you kept food logs to track potential culprits so you can pinpoint, or at least narrow down, the problem?
Good luck being a food detective! And don’t hesitate to seek medical advice if all of the above suggestions fail to find a solution. A consultation with a local sports dietitian for a nutrition check-up can be very helpful! See www.SCANdpg.org for a referral network.
Please add your comments if you have found a solution not mentioned above!

Nancy, which brand of amino acids should I buy? On amazon.com, there are 16 brands, ranging in price from $18 to $40. Help…!”
Answer: What makes you think you even need to buy essential amino acids? You can easily get them in protein-rich foods like eggs, yogurt, milk, chicken—any animal-based protein has all the essential amino acids your body needs.
The protein supplement industry has done an excellent job of making consumers believe they need to buy essential amino acids. Wrong! If you fuel-up your workouts with a protein+carb combination, such as a yogurt and banana, and then recover afterwards with another protein+carb combination such as lowfat chocolate milk followed by real foods at the next meal, you’ll be doing a fine job of getting all of these building blocks of protein. Rest assured, you could more wisely spend your money on protein-rich foods, not amino acid supplements, and get the results you want from your workouts.
Just to define the “lingo”: Proteins are made from many amino acids, just like words are made from many letters. Some of these amino acids— the essential amino acids—need to come from food, because the body cannot make them.
Here are a few ways to get two of the essential amino acids, isoleucine and leucine. Because pure amino acids taste nasty, I’ll get mine from yummy chocolate milk and real foods at meals any day!
If your skinny high school son is pestering you to buy a weight gain supplement because he’s sure it will create bulging muscles by breakfast, think twice and save your money!
As you can see from the chart below, all weight gain supplements are expensive and offer nothing you cannot get via food. A hefty peanut butter and jelly sandwich and a tall glass of milk aids weight gain at a far lower price tag than an equal amount of calories from Muscle Milk.
Food-home based Calories Price Cost/100 calories
Granola (1 cup) + 500 $1.00 $0.20
8-oz 2% milk
Sandwich: PB & J 650 $0.95 $0.15
(3 Tbsp PB, 2 Tbsp J)
Chocolate milk, 16-oz 300 $0.60* $0.20
Instant breakfast 250 $0.80 $0.32
Grape Juice, 16-oz 280 $1.00 $0.36
Muscle Milk, powder 310 $1.78 $0.57
Drinks-on the run
Nesquick, 16-oz bottle 300 $1.79 $0.60
Ensure, 8-oz bottle 250 $1.75 $0.60
Muscle Milk, 14-oz bottle 230 $3.59 $1.56
As you can see, buying bottles of read-to-drink meal replacements can quickly get expensive.
A money-saving alternative is to make your own weight gain drink:
In the morning, blend 1 quart of 2%-milk with 4 packets of Carnations Instant Breakfast and 1/2 cup powdered milk (1,000 calories total). Toss in a banana or other fruit for more calories. Drink half at breakfast and take the rest with you in a travel mug. Yummier than most commercial products—and no vitamin-fortified taste or smell.
Among my clients, I’ve observed that skinny athletes who have trouble gaining weight tend to be good fidgeters. They twiddle their fingers, swing their legs backand forth while sitting, and seem unable to sit still. All this involuntary movement burns calories. In comparison, the folks who complain about their inability to lose weight generally sit calmly, barely blinking their eyes. They may complain they have a “slow metabolism.” Doubtful. Their metabolism is likely normal, but their propensity to sit calmly is the problem. Compared to the fidgeter, they save themselves a lot of calories!
The technical term for the spontaneous movement often seen in skinny people who have difficulty gaining weight is Non-Exercise ActivityThermogenesis or N.E.A.T. NEAT includes not only fidgeting but also pacing while you talk on the phone and standing (not sitting) while you talk with a teammate. If you overeat, activation of NEAT helps you dissipate excess energy by nudging you to putter around the house more, choose to shoot some hoops, or (yikes!) feel motivated to vacuum and clean the house. If your body’s ability to activate NEAT is low, then you likely gain weight easily. NEAT can predict how resistant you'll be to gaining weight.
If you are overfat, the next time you start to complain about your slow metabolism, think again. Maybe you should start fidgeting and moving more throughout the daytime?
If you are skinny, the next time you complain about being unable to gain weight, think again. Can you try to stop fidgeting and pacing?
Most people on weight-reduction diets believe that having a salad for meal is a low calorie option that’s preferable to eating a Whopper or a Big Mac. Not always the case. Many salads come loaded with dried fruits, nuts, avocado, corn, and beans. Nutritious ingredients, yes, but caloric—especially if lots of cheese is sprinkled on top.
Salad dressing can be a real calorie-killer. Even a little bit of dressing on a big salad can become a LOT of dressing! Perhaps that’s why I’ve observed that people who eat salads for meals tend to be heavier than people who eat sandwiches. As for myself, I’ll take my sandwich with a small (but colorful) side salad.
For athletes interested in bulking up, creatine is commonly a topic of discussion. While I typically recommend hard work and smart nutrition over taking a creatine, here is some information about creatine, to help you determine if you want to make it a part of your sports supplement program. The information is taken from a recent article in the Journal of the International Society of Sports Nutrition.
• Your liver and kidneys (and to a small extent, your pancreas) produce about 1 gram creatine per day and store it in your muscles. Your body will produce less creatine if you start taking creatine supplements, but this soon changes when you stop taking the supplements.
• Creatine is found in meat. Hence, meat-eaters consume about 1 gram creatine per day but vegetarians (and others who do not eat beef, chicken, fish or other meats) have lower amounts of creatine stored in their muscles.
• The average 154-lb (70-kg) man stores about 120 to 140 grams of creatine; taking creatine supplements can increase creatine levels inthe body.
• Higher creatine allows for more rapid ATP regeneration between resistance training sets. This allows athletes to maintain a higher training intensity and stimulates greater muscle strength and size.
• A typical supplementation protocol is: Loading phase: four 5-gram doses taken throughout the day (20 grams total/day) for five days, followed by 3 to 5 grams creatine per day to maintain.
• Some athletes have no response to creatine supplements. Perhaps these non-responders already had initially high creatine levels? If so, this suggests a maximum size for the creatine pool.
• Some athletes show an 8% to 14% improvement in 1 Repetition Max (the heaviest amount of weight a person can lift)—but not everyone experiences such a response.
• Vegetarians who take creatine tend to have a larger increase in lean muscle mass compared to non-vegetarians—5.3 lbs vs. 4.2 lbs (2.4 kg vs. 1.9 kg) respectively. Note: That's only one pound more ... not much!
•Although creatine has been shown to be most effective with anaerobic intermittent exercise such as lifting weights, it might also help athletes such as sprinters who do intense aerobic exercise that lasts more than 150 seconds (2.5 minutes)—but creatine’s effects diminish as the duration of the exercise increases over 150 seconds. Creatine’s benefits may be related to improving one’s anaerobic threshold.
•Creatine combined with high intensity or long duration exercise and a high carbohydrate diet can contribute to higher muscle glycogen stores.
• Creatine can act as an effective antioxidant after intense resistance training sessions.
• Post-exercise creatine can favor an anabolic environment and improve the recovery process.
• Because creatine gets stored with water, it increases intracellular water content. This can result in water-weight gain, increased muscle stiffness, and reduced range of motion.
• Creatine has not been well-tested in athletes younger than 18 years of age. Some speculate taking creatine might be a stepping-stone for kids that leads to more dangerous products like steroids (though this is just speculation).
• Creatine Guidelines for teen athletes include:
-Only recommended when the athlete is a serious competitor and is post-puberty.
-The athlete is eating a well-balanced sports diet that optimizes performance.
-Both athlete and parents understand the effects of creatine supplementation and approve of taking the supplement. No one can guarantee safety.
-Qualified professionals supervise the supplementation of only reputable brands of creatine supplements.
-The athlete does not take more than the recommended dose.
• Creatine supplements come in many forms, including in combination with protein and carbohydrates. More research is needed to determine if one style is the most helpful.
ª Negative health reports associated with creatine are few. The isolated reports suggest the athletes took high doses and had undiagnosed renal disease.
• Creatine is not associated with increased cramps or injuries. If anything, creatine holds more water in the body, and this might decrease the risk of dehydration.

I like to stop at a convenience store during my long runs and buy a cola. Everyone else is drinking water or sports drink. They give me a hard time for drinking soda. Is there anything wrong with drinking cola on long runs?
Soda is sugar water .. . just like a sports drink. To make soda into a sports drink, dilute it in half with water and add a dash of salt (or munch on a few pretzels alongside the soda). The sodium (salt) enhances fluid retention.
Soda such as cola offers 100 calories per 8 ounces; Gatorade offers about 50 calories per 8 ounces. Both have few nutritional merits. Because a sports drink is more dilute than cola, it is easier to absorb and will empty quicker from the stomach. Hence, during intense runs, or in hot weather, when rapid fluid absorption is important, you might want to drink water alongside the cola to dilute it.
The caffeine in cola may be one reason you prefer it over a sports drink. Caffeine, particularly in combination with carbohydrates (i.e.,the sugar in soft drinks), is known to enhance performance. Although once thought to have a dehydrating effect, we now know that it not true.
As long as the cola settles well, without creating belching or stomach aches, you have my blessing to enjoy it during extended exercise. It is just one way to consume the 200 to 300 calories from carbohydrates you need per hour of running. The cola will help you maintain high energy and enjoyment of the run.
Granted, a wholesome breakfast or healthier pre-run snack to fuel the first hour is nutritionally preferable to relying on sugar-water. But during extended exercise, sugar in any form will help keep you from hitting the wall. The guidelines are to limit your sugar intake to 10% of your calories. That's 200 to 300 sugar-calories per day .... that means, one soda during a long run is OK but four sodas for meals and snacks is another story.
How much protein does a weight-lifter need to get an optimal response from exercise? --Is it an absolute amount or grams per kilogram body weight?
Speaking at a symposium spononsored by PINES (www.PINESNutrition.org), protein researcher Daniel Moore PhD of the University of Guelph in Canada reported that for generalized advice, 20 grams of post-exercise protein does the job for the average athlete. More is not better. In a study that compared 20 and 40 grams, the higher 40-gram dose offered minimal additional benefits for muscle protein synthesis. Don’t waste your money on supplements, and also don’t fill up on protein while ignoring your needs for carbohydrates to refuel your muscles. You want to consume three times more carbs than protein!
For more personalized advice, the best bet is to determine post-exercise protein needs according to body weight. Moore recommends targeting about 0.25 g protein per kilogram body weight (that’s about .11 gram per pound) to maximize muscle protein synthesis. This means:
-- a 50 kg (110 lb) female would need approximately 12.5 grams protein post-exercise
--a 100 kg (220 pound) man, would need about 25 grams protein post-exercise.
Any excessprotein primarily gets burned as fuel or stored as fat.
You want to offer your muscles a continous supply of protein, so enjoy repeated “doses” throughout the day. Most athletes do this naturally with meals and snacks.
For certain! At a recent meeting sponsored by P.I.N.E.S. (an international group of sports dietitians who met at the American College of Sports Medicine’s Annual Convention, June 1, 2012 in San Francisco), Dr. Stuart Phillips, PhD of McMaster University in Canada reminded us that rapidly-growing infants require 1.3 grams protein per kilogram, whereas the RDA for fully-grown adults is 0.8 grams protein per kilogram body weight. Adults need less protein because they simply are not growing as fast as infants and young children.
The same goes for novice athletes who are building muscle; they have higher protein needs than a sedentary person. The Recommended Dietary Allowance (RDA), according to Phillips, is really a minimal dietary allowance for athletes. Just as children have higher protein needs during growth periods, athletes also have higher requirements to 1) build muscles and 2) maintain a flow of amino acids for processes that may function at a higher rates in athletes than non-athletes (such as the synthesis of protein, neurotransmitters, and immune proteins).
Phillips supported the ACSM Position Stand on Nutrition for Athletes, citing their recommended daily protein intake of 1.2 g/kg body weight (0.5 g/lb) for endurance athletes and 1.7 g/kg body weight (0.75 g/lb) for strength athletes.
Most elite athletes eat 1.6 grams protein/kg/day, spread over 4 to 5 meals and snacks, so they already meet this higher protein recommendation without the use of supplements. Hence, the real answer to the question “do some people need more protein than others?” is yes, but they likely get that extra amount in their standard diet; they just have less excess. Them ore you exercise, the hungrier you get and the more protein you are likely to eat.
Beets, rhubarb and arugala are nitrate-rich foods.Sports nutrition research indicates the natural nitrates they contain can significantly improve running performance when eaten three-hours in advance of exercise. The nitrates convert into nitric oxide, a gaseous signaling molecule that acts as a critical biological messenger. Nitric oxide dilates blood vessels, lowers blood pressure, reduces platelet stickiness, and allows a person to exercise at a submaximal pace using less oxygen. This info is helpful for not only athletes but for unhealthy people with lung and circulation problems.
This nitrate-rich recipe is one of many tasty suggestions from the website of food-lover Eileen Behan RD www.ForTheLoveOfFood.org.
6 small red beets (12 ounces, raw or cooked), peeled and sliced very thin
1/2 large pink grapefruit, juiced
1/2 tablespoon red wine vinegar
Salt and pepper, to taste
1 1/2 tbsp olive oil
8 ripe strawberries
1/2 lemon , juiced
1 tbsp olive oil
1-cup chopped (1 stalk) rhubarb
4 cups arugula, washed and dried
1. In a medium bowl, toss beet slices (either raw or cooked) with the juice and zest of the grapefruit-half, vinegar, pinch of salt and 1 1/2 tbsp olive oil. Marinate, at least 15 minutes to 4 hours.
2. Cut the strawberries into quarters. Toss with 1 tbsp olive oil, and juice from the lemon.
3. Prepare the rhubarb sauce: in a food processor, pulse rhubarb with 2 tbsp water and puree until smooth.
Just before serving, strain the marinated beets. Toss beets with the strawberries. Arrange the greens on a platter and top with the beets and strawberries. Put a dollop of rhubarb purée in the center. Optional: drizzle with a little olive oil.
The Boston Marathon is over and we hope that you are proud of your efforts! You have spent many months preparing for this race both physically and mentally; it’s common to come to the end of the race and wonder what’s next. Many runners worry about how to adjust their eating plan. Here is a short guide on adjusting your eating after training.
Assess your weight and define your goals
Before adjusting your eating plan, assess your current weight. Did you lose, gain, or maintain your weight during training? Then, determine if you need to adjust or maintain your post-race weight.
Listen to your body
Your body is very good at adjusting your food intake for training. That is, as you increase your training, you are hungrier and as you decrease your training you feel less hungry. Therefore, within the week after the big race, your appetite should decrease. This is your body telling you to eat less.
Writing down what you eat for 3-5 days can be helpful to see when, where, and how much you are eating. Even better, record how hungry you were before and after you ate. This can help you understand if you are eating enough to prevent hunger, or perhaps you’re just eating out of habit. Food logs will show you where the best places are to cut back, or perhaps identify meals in which you aren’t eating enough.
Eat throughout the day
The best way to manage hunger and maintain energy throughout the day is to fuel your body on a regular schedule. People generally get hungry about every 4 hours, so try to plan meals or snacks at least every four hours.For example, breakfast at 7am, lunch at 11am, 2nd lunch (or snack) at 3p, and dinner at 7p. For some it may work better to break this up into more, smaller meals in 3 hours blocks, so find what works for you.
Not eating enough at breakfast, lunch, or second lunch can lead to overeating at dinner. However, since you’re exercising less than you were during training, your body may be satisfied with smaller portion sizes at each meal. But, don’t skip meals! For example, instead of eating a large bagel with peanut butter, a banana, and a large glass of orange juice at breakfast, morning runners maybe only need 2 pieces of toast with peanut butter, half a banana, and a small glass of orange juice (or just water). Pay attention to when you feel full – your appetite is a good gauge for how much you need to eat.
If your goal is to lose weight, fuel your body throughout the day and chip off 100-200 calories each evening. You can achieve this by eating a smaller dinner, choosing fruit for dessert instead of ice cream, or choosing to drink water instead of wine or beer. Eat a mix of carbohydrates, lean protein, and healthy fats at each meal. Choose fiber rich carbohydrates such as fruits, vegetables, and whole grains to keep you feeling fuller, longer. Protein and fat also help slow digestion, adding to a feeling of satiety.
Make an appointment with a registered dietitian
For a more personalized plan, make an appointment with a registered dietitian (RD). An RD can help assess your current weight and diet and provide you with the best eating plan to move forward. Visit the Sports,Cardiovascular and Wellness Nutrition (SCAN) website to find an RD that specializes in sports nutrition.
