Can I eat fat and look good in tights?


By Emily C. Harrison MS, RD, LD.

Dancers tend to be cautious about fat in their diets. This is completely understandable given that we have to look good in tights and fat is a very concentrated source of calories. Fats have nine calories per gram versus four calories per gram from carbs or proteins. But what about all the reported benefits of coconut oil, olive oil and omega-3s? Would a dancer’s bone health be at risk without adequate fat to help absorb and metabolize bone building vitamins D and K, both of which are fat-soluble? Plus, fat makes food more palatable, and helps you feel fuller longer.  Smart choices and moderation are what we need for this misunderstood, but tasty, nutrient.

How Much?

The American College of Sports Medicine recommends getting 25-30% of your total calories from fat. As a dietitian for dancers, I typically recommend getting 25% because it’s necessary, but we don’t want to get too much. It is saturated fat that you want to avoid. Recommendations are to get less than 10% of total calories from saturated fat. We all should entirely avoid trans fats. Trans fats undergo hydrogenation, which makes them more shelf stable. Baked goods, doughnuts, fried foods and chips are sources of this heart-damaging fat. As athletes, our cardiovascular system is a big part of what makes us perform well and it makes sense to eat foods that support the one muscle that never stops working. Most teenagers and adults can eat between 35 to 60 grams of total fat per day, but choose your sources of fat wisely, picking plants such as nuts, seeds, avocados and small amounts of unsaturated oils. Portions matter! All foods naturally contain some fat. Even green beans and other veggies have a little.  

What does 25% of total calories really mean?

It’s different for everyone, but for approximately 2,000 calories per day, 500 of those can be from fat. This amounts to up to 55 grams per day. A pat of butter, 1/3 hamburger patty or 2 tablespoons of avocado all contain about 5-8 grams of fat, but the different kinds of fats in these foods can have profoundly different effects on the body.  

The importance of fats

Fats provide critical biological functions in the body. Phospholipids are components of cell membranes, and glycolipids are components of brain tissue. Fat can also be an important fuel source during a long show. Fats are essential for the absorption of vitamins A, E, D and K. 

Different types of fat

You want to replace saturated fats with unsaturated sources. When you hear of saturated or unsaturated fats (both poly and monounsaturated), those terms are referring to the structure or the chemical bonds. The structure can influence how it is metabolized by the body and then how it is used by cells. Different types of fat can also have different effects on athletic performance. Coconut oil is popular now. While it is very saturated and should be eaten in moderation, it has the type of fat that can be absorbed rapidly and can be a quick fuel source before dancing.

Below are some examples of fat sources. These are all naturally a mixture of saturated and unsaturated fatty acids, but this gives a general idea of which fat sources are healthier options.

Saturated Fat (usually solid at room temperature) includes:

  • Meats, cheeses, butter, chocolate, coconut oil, palm oil, shortening, hydrogenated oils/ trans fats. 
    Linked to heart disease, hardening of the arteries, higher cholesterol, cancer, liver disease and poorer athletic performance.

Poly and Monounsaturated fats (usually liquid at room temperature) includes: 

  • Oils from flax, safflower, canola, olive, sesame. All seeds such as chia, flax, hemp, and sunflower. All nuts such as walnuts, almonds, peanuts.
    Linked to decreased cholesterol, better heart health, lower risk for cancer.

Omega-3s/ fish oils (Unsaturated and considered “essential” because the body can’t make them):

  • Flax and chia seeds, walnuts, cold water fish, canola oil, soy, wheat germ.
    Linked to decreased inflammation, lower risk for depression, improved brain function and better heart health.

Making good choices when dancing

Because fat slows stomach emptying and digestion, choose a high carbohydrate meal that is moderate in protein and low in fat one hour or more before a show or rehearsal. Nerves can affect digestion as we all know. Options could be a low fat meal of pasta with light marinara sauce (easy on the oil) or rice, veggies and edamame or a veggie burger on bread with a side of carrots. During long class or rehearsal days, try trail mix with nuts and seeds with a carb like pretzels or crackers. Add flax or chia seeds to your oatmeal in the mornings.

Anyone who is watching their weight and wants better performance doesn’t need to fear fat, they just need to be smart about not eating too much and getting their fat sources from plants.

Eating Right on a Dancer’s Budget


By Emily C. Harrison MS, RD, LD

I don’t know any dancers who have money to throw away.  Here are a few tips to help stretch those hard earned dollars.

Get your protein from more plant based sources

Protein from beans, peas, nuts, whole grains, seeds and soy is so much cheaper than animal based protein. Think about how much more a steak costs verses some beans and rice. If you buy the dried beans from bulk bins you will save even more.  Most beans are sources of protein, iron, potassium, folate and fibre. In general, plant based meals are lower in fat and calories but high in nutrients.

You can make totally organic (and delicious) homemade soup and rice and even add kale for about $2.00 per serving.  It’s easy to throw everything in a slow cooker or make something ahead of time for an easy meal after a long day of rehearsals.  Quinoa is a wonderful high protein grain that you can get for less than $0.50 per serving, and it cooks faster than rice for a quick week night meal.

Soy is a versatile and cheap source of protein. Add some tofu or endamames to a veggie stir fry.  Eat more plants in place of meat and dairy – you’ll be fighting off cancer and reducing your impact on the environment while saving money!

Think critically about your grocery store

Food companies are businesses, and their ads are designed to get you to buy food and more of it. The system is designed for higher and higher profits, but that’s not always what’s best for our waist line, wallets, or our health. The word “natural” is now used on everything from chips to cookies and ice cream.  “Natural” has no legal definition in the U.S. so it gets overused.  It can lure people into believing that chips are somehow good for you just because the word natural is on the package.

Health claims are also a big part of the advertising market. Some companies will put random vitamins and “functional” ingredients into all kinds of foods and beverages touting health claims that might be flimsy at best or even dangerous. One example is mega doses of vitamins in beverages. No one needs 1000mg of vitamin B or C in a juice. The body wasn’t meant to absorb nutrients in this way and it can cause problems.  Our bodies absorb nutrients best through real food.  Stick to the outside aisles of a grocery store where you will find fewer boxes and bags and more fresh ingredients.  We all like convenience, but we pay for it.  Chocolate bars are right at eye level at the checkout counter and high fat foods are placed at high traffic areas for a reason.  Bargains aren’t bargains if they are full of sugar, fat, or refined flour.

Is it really a bargain?

Buying in bulk might not always be a good thing. No one really needs a gallon container of cheese puffs.  Big box retailers of wholesale food items might be selling you much bigger portions of unhealthy packaged foods. Is a 20 pack of croissants really a deal when each one packs up to 400 calories?  Use care and read food labels if you shop at the big wholesale stores.

Some terms on packages are legally defined and can help when deciding what to buy. The term “organic” has strict guidelines, and while the system isn’t perfect, it is better to buy organic. But keep in mind that organic cookies are still cookies – enjoy them in moderation.  It’s better to buy organic fruits and veggies, even though they usually cost more.

“Low fat” means that the food item must have 3 grams or less of fat per 100 grams, or no more than 30% of calories from fat.  This can be helpful when looking at food labels. But one trick to be aware of is that “low-fat” baked goods often have way more sugar content than regular to make them taste better.  So those low-fat treats might still have close to the same number of calories.

Prepare food at home and avoid packaged foods

Less packaging = less cost. Planning ahead can save you lots of money. Having fruit and veggies ready to go at home make it easy to grab them while you are racing out the door to class. You are much more likely to eat well on a budget if you don’t have to pick something up from a deli or restaurant.  Have grapes washed and ready to eat in your fridge, peel and cut carrots yourself and put them into your own reusable containers. Keep a box of low calorie muesli bars in your car. When snacks are easy to grab, you are less likely to eat junk food which will cost you more money and many more calories.

Eat in season and reduce portions

Off season tomatoes shipped from miles away not only taste terrible, but are much more expensive. Shop local, support your farmers markets, and buy in season. You will get better quality food, with higher nutrients and your hard earned food dollars will stay in your local economy.

One of the main reasons for weight struggles are out of control portions.  Make smaller portions and serve food on smaller plates.  When eating out, split a main meal with a friend, or order an entrée size. You’ll save money, and won’t overload on calories.

You CAN eat well on a tight budget: plan ahead, make your own food, shop local, and eat more plants.

Hydration for Dancers


By Emily C. Harrison MS, RD, LD.

Even mild dehydration can affect performance.  Staying hydrated is extremely important to a dancer’s performance because the first signs of dehydration are fatigue and poor balance.  Thirst actually only kicks in after the body has lost 1-2 litres of water. If you are thirsty then you are already dehydrated.

The science

Water makes up approximately 60% of body weight and is the largest component of the human body.  The muscles we work so hard to develop as dancers (skeletal muscles) are about 73% water, your blood is about 93% water and even bones and teeth contain some water. Water is critical for maintaining homeostasis within the body and important in the thousands of biochemical and physiological functions our bodies go through every day. Water aids in digestion and is important in the transport and elimination systems of the body.

Overheating and performance

It’s important for dancers to know that being properly hydrated helps keep the body from overheating. Helping the body promote heat loss when dancing full out will improve athletic performance and aid in recovery. This is especially important for dancers wearing hot costumes and performing under stage lights. Sweat losses during performance can be significantly more than during rehearsal of the same piece. This is why drinking regularly (even small, regular sips) is an important habit during a show.

How much is really needed? Can a dancer get fluids from other things besides water?

The American College of Sports Medicine recommends that athletes (we all know that dancers are athletes) start their exercise already hydrated with about 500ml of beverage taken before you begin. Then drink 150-300ml every 20 minutes or so. This means that your reusable water bottle should be your constant companion in the studio or backstage.  Every dancer is a little different but pre-professional and professional level dancers should aim for about 2800-3500ml of fluids every day.  That’s about 12 – 15 cups.  About 20-25% will come from foods like fruits and veggies, but about 80% comes from what you drink.  Aim to get most of your fluids through water, but juices, sports drinks, and even tea and coffee can be counted toward that goal. Some dancers find that mixing 50% sports drink with 50% water in their reusable bottles helps them get through long rehearsals or classes. This is because sports beverages contain a source of readily available energy (calories) and electrolytes that are lost in sweat.

But I want something besides just water…..

Prevent dehydration by eating lots of fruits and veggies.  Consider melon, squash, oranges, apples, pears, grapes, leafy greens and salads in addition to beverages like tea, whole fruit ice-blocks, sports drinks, smoothies, soy milk, almond milk, and yoghurts.

What about caffeine?

Caffeine makes us more awake and is known to enhance athletic performance. But there can be too much of a “good” thing.  Caffeine is a central nervous system stimulant, not a source of energy.  Yes, caffeine can also promote water loss and dancers should limit caffeine, but those beverages can still count toward your daily intake. I always recommend limiting or avoiding soft drinks. They are empty calorie bombs and can make bones weaker.  One cup of coffee is fine, but being overly jittery doesn’t help your dancing.

So be good to your body and good to the earth by taking your reusable water bottle with you everywhere and refilling it often!

Bone Health for Dancers


Nutrition recommendations for preventing and recovering from bone breaks, stress reactions, or stress fractures.

By Emily C. Harrison MS, RD, LD

With our highly active and high impact lifestyles, dancers can be prone to bone stress. What can you do ensure your bones are ready for the demands of dance?

Bone is living tissue, and good bone health requires good nutrition.  One way to avoid stress fractures/ reactions is to get adequate calories from protein, carbs, and fat. Calorie needs for dancers can vary depending on your size, age, gender, and activity level.  (See Dancernutrition.com for information on estimating calorie needs).  Going for long periods of time without eating or extreme dieting will compromise bone mineral density and jeopardize your bone strength. Cutting your calories too heavily will not help you become a stronger dancer.

Hormones also play a big role in bone health.   Decreased or absent menstruation in females is a warning sign. Please see a health care professional if dietary intake or menstruation is a problem.

Vitamins and Minerals for bone health, ages 13 and up
Calcium: 1300-1500 mg
Vitamin D:  10-15 micrograms (600-800 IU) avoid large doses and get 15 min of sun/day
Vitamin C:   100 mg (avoid large doses)
Vitamin K:  75-90 micrograms
Phosphorus: 1250 mg/day

Did you know that you can get all these from food sources?

Protein: Did you know that too much can actually compromise bone health over time?
Protein needs vary throughout our lifespan. For more information about recommended protein intake read Protein Needs for Dancers from the November Edition. More than enough protein is not necessarily better. Dancers who are adolescents and still growing, as well as engaging in athletic activity several times per week, can estimate protein on the higher end of the range, but shouldn’t over do it.  High protein diets can lead to more calcium being lost from the bones – a big problem for dancers who are at higher than average risk for stress fractures.  Protein overload = weaker bones.  Get your protein from food sources like beans, nuts, seeds, whole grains and if necessary, get small amounts from meat or dairy.  Protein supplements or powders are not necessary and can even be dangerous.  

Dietary sources of bone building nutrients:

  • Everyone knows that dairy is a great source of calcium, but there are other plant-based sources of calcium too, like almonds. If your dairy intake is restricted, choose calcium fortified soy milk, almond milk, or orange juice w/ calcium.
  • Greens: spinach, kale, collards, chard
  • All fruits (great sources of vitamin C and phytonutrients)
  • Tuna, eggs, beans
  • Sunflower seeds, almonds
  • Enriched cereals, oatmeal with almond milk

Protein Needs of Dancers


How much, what kind, and when?

By Emily C. Harrison MS, RD, LD


Do dancers need extra protein? Do they need to use powders, drinks, shakes or amino acid supplements or should they just eat more?  In the wake of the highly misguided “low carb” craze and in light of all the recent headlines about how  eating too much meat and dairy can increase risk for long term diseases…what is a dancer to do?  How much is enough, what kind of protein is best, and does timing matter?

How Much?

Yes, dancers need more protein than the average non-athletic person, particularly if they are still growing adolescents.   However, it is important that we get away from this incorrect idea that most of our food should be protein and that we should avoid carbohydrates. Protein is important, but too much protein is actually harmful to the body.  Everyone is a little different, but it is recommended for athletes that 12-15% of total calories should come from protein.

What does that mean exactly?

Everyone’s caloric needs vary, but if a dancer needs approximately 2000 calories a day, then they need about 60-75 grams of protein in their diet. (This is an average and not intended to be the amount for all).  

Here are examples:

A 52 kg female dancer needs about 60-78 grams of protein each day.
A 77 kg male dancer needs about 90-108 grams
There’s a range, because different dancers have different activity levels and therefore need more calories.

Real food examples of protein content:  

Typical fast food hamburger 27 g protein, 600 calories, 40 g fat
85g grilled chicken 20 g protein, 111 calories, 3 g fat
1  cup black beans and rice 12 g protein, 222 calories, 1 g fat
Quinoa cakes pan fried in canola oil 8 g protein, 300 calories, 12 g fat
1 cup soy milk, chocolate flavoured 5 g protein, 141 calories, 3.5 g fat
1 cup black eyed peas, walnut, and couscous salad 10 g protein, 224 calories, 5.2 g fat

 

What Kind?

Unless a dancer is dieting or restricting calories (which I generally don’t recommend), they can easily meet their protein needs through food alone. Supplemental protein is expensive and unnecessary. In general, people in Western society, including athletes, get far more protein than they need. It is a myth that you need to load up on protein powders, drinks, or bars or that it should form the bulk of your food intake. Carbs are actually far more important fuel for working dancers. Protein drinks and bars can be convenient for busy dancers, but it is always better to get nutrients through real food. Research shows that the risk for long-term disease such as stroke, diabetes, heart disease, and cancer is significantly decreased when the majority of protein consumption comes from plant-based foods. Some examples are beans, peas, lentils, nuts, seeds, grains, and of course vegetables.  Whey protein (isolated from cow’s milk) has been in the news lately as good for recovery.  Some whey protein supplements, such as in a recovery beverage, might help dancers bounce back on a heavy show weekend, but there can always be too much of a good thing. 

When?

The body is better able to utilize protein when it is eaten in moderate regular doses throughout the day and also post workout.

Try to divide up total daily dietary protein into regular meals and snacks. For example, a professional level dancer would need to eat a little protein (10-20 grams) every 2-3 hours during the work day.  Aim for at least 6 small meals/ snacks per day.

Try to eat 10-20 grams of protein with a balanced meal within 1 hour post-exercise. However, some studies show that the body’s muscle building/repair response will still occur if the protein is eaten within 24 hours of exercise.  

According to K. Tipton PhD “there is a limit to the amount of protein that will effectively increase the anabolic response”. Essentially, when an athlete eats up to approximately 20 grams of protein at one sitting then it may be used to build muscle, but there is no difference in muscle response when given 20-40 grams at a time. So it seems that protein loading doesn’t do any good. When total dietary protein is ingested in small, frequent amounts throughout the day then the body responds much better and can utilize it for what protein is meant for.  Eating beyond the body’s capacity to use it, means it gets stored as fat or used as fuel. And the body doesn’t really like to use protein as a fuel source.  

Excess protein…what’s the problem with eating too much?

When protein is used as fuel, particularly when there is not enough carb or fat in the diet, it is hard on the body and can actually do more harm than good. Here’s why:

  • The body doesn’t like to use protein as fuel or energy. The body wants to spare valuable protein for muscle building, making hormones, enzymes, controlling fluid balance, etc.
  • Excess protein means excess nitrogen, a part of protein (amino acids) that must be removed. This can be hard on the kidneys. More importantly water gets excreted in this process and can lead to dehydration. 
  • High protein diets can lead to more calcium being lost from the bones, a big problem for dancers who are at higher than average risk for stress fractures.  Protein overload = weaker bones.
