We were thrilled to be among the distinguished speakers at the Better Bone Health Forum last month, organized by Osteoporosis Canada. For better bone health, remember these 4 Ms:

MAXIMIZE bone density by getting enough calcium and bone-building nutrients during childhood and adolescence. Maximum bone density is reached by about age 18 (for girls) and age 20 (for boys). Milk, cheese, yogurt, kefir and fortified soy beverages are some of the best sources of calcium. Calcium is also found in foods such as canned salmon with the bones, leafy green vegetables, calcium-fortified orange juice, nuts, seeds and beans.

MAINTAIN bone density during your adult years to keep bones strong and healthy. Swap out one coffee a day and replace it with a latte. Cook and bake with milk products and calcium-fortified products. Protein, potassium and vitamin D all help your body better absorb calcium. Enjoy a variety of fruits, veggies, whole grains and lean proteins to get a good mix of these vitamins and minerals.

MINIMIZE the bone loss that naturally occurs as we grow older. After menopause, a woman’s risk for osteoporosis rises. Get a bone density check. After the age of 50, consider taking a vitamin D supplement of 400 IU every day. Talk to a dietitian about the need for calcium supplements.

MOVE your body! Try to be active every day. Exercise builds strength in your muscles which can improve your balance and help prevent falls. Strength training or resistance training activities such as push-ups or lifting weights are recommended for building muscle strength. Weight-bearing activities such as walking, running, hiking, dancing, tennis and golf will also keep your muscles and bones strong. It’s never too early or late to take care of your bones!

Dare to Compare: Coconut Water versus Sports Drink

Athletes of all ages are turning to these beverages for hydration. What’s the difference?

coconut-water-vs-sports-drink

Overall, unsweetened coconut water has fewer calories, carbohydrates and sodium than a typical sports drink. For general hydration, coconut water is fine. Look for the brands with no added sugar.

However compared to sports drinks, coconut water has too much potassium and not enough sodium or carbohydrates for optimal hydration during and after exercise / competitions.

According to the Dietitians of Canada, sports drinks may be beneficial if you:
– exercise hard for at least 1 hour
– exercise at high intensity (e.g. soccer, hockey, basketball)
– sweat a lot / have salty sweat
– wear a lot of protective gear or equipment such as for hockey or football
– train or exercise in the heat and humidity
– need to replace fluids and energy quickly such as during hockey tournaments
– train or exercise more than once a day.

Sports Nutrition – top tips for athletes

The Rio Olympics are ON! We’re amazed at the commitment and performance of the athletes. You may know that sporting activities are enhanced by well-chosen nutrition strategies. Did you ever wonder what the top evidence-based nutrition tips are for athletes that help drive their best performance? Earlier this year, Dietitians of Canada published a summary of the latest scientific evidence in sports nutrition.[1] Whether you are a ‘weekend’ athlete or training for challenging events, here are our top tips that could help your performance be at its best.

Top tips for sports nutrition

  • Carboydrates are the key fuel for energy and eating them in balanced amounts is important to perform at your best. Studies show that during exercise that lasts longer than one hour eating carbohydrates increase endurance capacity which means you can cycle, run or play hockey longer and not run out of steam.
    Dietitians Tip: carbohydrate intake is not necessary if you exercise for less than 45 minutes. However, if you exercise with intensity for more than an hour but less than 2.5 hours in one duration, do consume about 30-60 grams of carbohydrates per hour. Many athletes use sports drinks or gels to top up their carbs during performance. It’s important for athletes to identify a personal plan that best meets their individual needs for energy, hydration and stomach comfort.
  • Protein builds muscle and performance. Eating the right amount of protein at the right time has critical implications for athletes. There is strong evidence that among athletes and recreationally active adults, eating protein (examples are egg, milk, casein, whey, lean meat) within the first two hours after exercise will boost the body’s muscle building capacity.
    Dietitian’s Tip: to build muscle eat 0.25-0.3 g protein/kg body weight (equivalent to 15-25 g of protein for most athletes) within the first two hours after exercise and as part of meals every three to five hours. If you are interested in protein supplements, whey is best since it’s a fast absorbing high quality protein. Very high protein intakes (ex. more than 40 grams per meal) after exercise will not boost muscle building further.
  • Hydration is important because during exercise your body loses extra water through sweat and could become de-hydrated. In sweat your body also loses minerals such as sodium and some potassium, calcium, and magnesium.  Depending on the sport or exercise you do, you could lose anywhere from 0.3 to 2.4 L (about 1¼ to 10 cups) of sweat per hour! Dehydration places strain on your body and you could get over-heated tired and hurt your performance.  Be sure to top up on fluids when you’re feeling thirsty and look for signs of dehydration such as dizziness, headache and muscle cramps.  The ‘pee test’ is a good way to check your hydration before exercise.  Aim for urine that is a pale yellow colour.
    Dietitian’s Tip: To stay well hydrated plan strategies for your fluid management before, during, and after exercise.  For example, drink water throughout the day and before exercise, drink 1-2 cups of fluid. Studies show that during exercise beverages with added flavour or sports drinks (which have added flavour, carbohydrate and electrolytes like sodium and potassium), generally result greater consumption and therefore better maintenance of hydration during intense exercise than plain water.[2]
  • Registered Dietitians are the most trusted nutrition experts to help you with your personalized nutrition plan that’s needed for top performance.  If you would like help with your eating pattern, a Registered Dietitian can assess your diet and give you recommendations  ‘for the appropriate type, amount, and timing of intake of food, fluids, and supplements to promote your optimal health and performance across different scenarios of training and competitive sport.’  You can access the position paper on Nutrition and Athletic Performance at: www.dietitians.ca/sports

Protein – A Nutrient in Focus – December 3, 2013

According to research by the Dairy Farmers of Canada, consumers are most concerned about getting enough vitamins and protein. Dr. Rajavel Elango, Assistant Professor at the University of British Columbia noted that current protein intake recommendations are inadequate. In fact, optimal protein and amino acid intakes could have health benefits.

Dr. Douglas Paddon-Jones concurred, stating that adequate protein intake has the potential to maintain healthy muscle and prevent age related sarcopenia (muscle loss). A threshold of 30 grams of protein represents an promising strategy for adults wishing to maintain muscle mass while control their body fat.

As educators and food innovators, let’s look for opportunities to help consumers reach their ideal protein intake for optimal health.
