    • Q.
      Is there a difference between multigrain and whole grain?
      • A.
        Yes, there is a difference. While "multigrain" and "whole grain" sound similar, they do not mean the same thing. Whole grain means that all parts of the grain kernel - the bran, endosperm, and germ – are used. Multigrain means that there is more than one type of grain in the product, but not necessarily whole grains. Look for the word "whole grain" on the label and as one of the first ingredients in the ingredient list.
    • Q.
      Are the 100 calorie packs a good choice?
      • A.
        The 100 calorie snack packs are great for portion control, but may not do their duty as a snack. A snack should keep you satisfied between meals to help you avoid overeating at your next meal. The 100 calorie packs are typically mini cookies that are high in sugar and lack fibre and protein. Instead, try one of these portable snacks that provide some fibre and protein to help you feel full longer:
        • a single serving of low-fat yogurt and an apple
        • trail mix made from whole grain cereal, unsalted nuts and dried fruit
        • baby carrots or red pepper strips with hummus dip
        • half a whole grain bagel with peanut butter
    • Q.
      Is sea salt healthier than regular table salt?
      • A.
        Sea salt is often marketed as a more natural and healthy alternative to table salt, but both contain similar amounts of sodium. Too much sodium in the diet may lead to high blood pressure, a risk factor for stroke, heart disease and kidney disease. Sea salt contains about 31% sodium by weight, along with small amounts of calcium, potassium and magnesium. Table salt contains 39% sodium by weight and small amounts of potassium iodide. Both types of salt should be limited to reduce sodium intake.
    • Q.
      I always hear that "breakfast is the most important meal of the day," but I’m never hungry in the morning. Does it really matter if I eat breakfast or not?
      • A.
        Enjoying a healthy breakfast is a great way to start your day. It’s important to “break the fast” after not eating throughout the night, which can help to improve your energy level, reduce your hunger and prevent impulsive eating later in the day. A healthy breakfast should include three of the four food groups, such as whole grain cereal with milk and a banana.

        Often people who skip breakfast regularly don’t feel hungry in the morning because their bodies have become used to ignoring their hunger signals. To get back to a regular eating schedule that includes breakfast, try starting with something small in the morning, like a piece of fruit or slice of toast. When having breakfast becomes a routine, work towards making it a balanced meal by including three food groups.
    • Q.
      What does % Daily Value mean on a food label?
      • A.
        The % Daily Value, found in the nutrition facts table, is based on recommendations for a healthy diet. It puts nutrients on a scale of 0 to 100%, which tells you if there is a lot or a little of a nutrient in a serving of that food. For example, a food that has 30% Daily Value for fibre means that you're getting almost a third of your day's recommended intake for fibre by eating a serving of that food.

        Try to follow the 5/10/15 Rule for % Daily Value:

        For nutrients you want to decrease look for a % DV that is:
        • 5% or less of total fat, sodium and cholesterol
        • 10% or less of saturated fat and trans fat
        For nutrients you want to increase look for a % DV that is:
        • 15% or greater of calcium, iron and fibre
        You can also compare similar foods or different brands of a food using the % Daily Value. Remember to look at the serving sizes on each label to see if you are comparing similar amounts first.
    • Q.
      Should I use an energy drink during exercise?
      • A.
        For most activities, drinking water before, during, and after your workout is the best way to keep you hydrated. If you’re working out at a very intense level for an hour or more you may want to use a sports drink.

        Energy drinks are different from sports drinks and are not designed for hydration during exercise. Energy drinks contain too much sugar for your body to digest quickly during exercise and may cause stomach discomfort. They are often carbonated which makes it hard to drink enough to stay hydrated. Additionally, energy drinks contain caffeine, which may make you alert for a short time but tends to be followed by feelings of low energy. It is not known if other ingredients in energy drinks like taurine and glucuronolactone are safe, especially when mixed with caffeine.
    • Q.
      Is brown sugar or honey better for me than white sugar?
      • A.
        Brown sugar and honey are not more nutritious than white sugar. All sugars, including honey, brown sugar, white sugar and maple syrup have the same nutritional value and are handled by your body in the same way. All sugars provide similar amounts of energy (about 4 calories per gram or 16 calories per teaspoon) but no significant amounts of other nutrients.
    • Q.
      I hear so much about salt these days – how can I cut back?
      • A.
        Canadians consume an average of 3400 mg sodium daily, more than double the 1500 mg adults 19-50 need, and even above the 2300 mg ‘upper tolerable intake level’, which is the most adults should take in per day. Most of that sodium doesn’t come from the salt shaker – almost 80% of the salt in the Canadian diet comes from processed foods.
        To reduce the sodium in your diet:
        • Prepare more of your meals and snacks at home.
          Foods from restaurants or fast food are high in sodium.
        • Read food labels and choose products with lower sodium content.
          Look for foods with the claims “salt-free” or "low in sodium"
        • Eat more fresh, unprocessed foods instead of pre-packaged foods.
          Frozen dinners, deli meats, salad dressings, rice and noodle mixes, and other processed foods are often high in sodium.
        • Prepare foods with little or no added salt.
          Try using a twist of lemon juice, herbs and spices, or sodium free seasonings instead.
        • Ask for nutrition information at restaurants and choose lower sodium foods.
          Many chains now make nutrition information available online or in the restaurant.
    • Q.
      Will a low-carb diet help me lose weight?
      • A.
        There is no evidence that low carbohydrate diets are more effective than higher carbohydrate diets for long term weight loss. It is total calories that are most important in weight management. Low-carb diets can be difficult to follow because food choices are so limited, and you may have trouble meeting your nutrition needs. Carbohydrate sources like whole grains, vegetables and fruit, legumes and milk contribute valuable nutrients that the body needs. A diet that has a balance of carbohydrates, protein and fat may be easier to stick to and therefore easier to maintain weight loss as well. Rather than making drastic changes to the way you eat, set small healthy eating goals and lead an active lifestyle to help reach and maintain a healthy weight.
    • Q.
      I don’t like water, but I switched from regular pop to diet pop – isn’t that just as good since it has no calories?
      • A.
        Replacing sugar-sweetened beverages (such as regular soft drinks) in the diet with water can reduce the total daily energy (calorie) intake, and may promote weight loss. Some studies have shown that the same effect is not seen when regular soft drinks are replaced with diet or calorie-free beverages. Remember that some diet soft drinks also contain caffeine (about 35-40mg per 355mL can) and sodium (up to 85 mg per 355mL can) but water does not.

        If you think that plain water is just too plain, why not try:
        • Adding slices of lemon, lime, orange or cucumber to your water
        • Floating a few frozen raspberries or blueberries in your water instead of ice cubes
        • Adding a splash of 100% fruit juice for a light flavour
        • Keeping a pitcher full of tap water handy in your fridge at home or in the office so it is always cold and ready to drink.
  • Physical Activity Questions
    • Q.
      Should I work out at a lower heart rate to burn more fat?
      • A.
        No, working out at a lower heart rate will not burn more fat than working at a higher intensity. You will burn a higher percentage calories from fat compared to carbohydrates (sugars) at a lower intensity, but you will burn far fewer calories overall and therefore less fat. So to burn more calories overall, including those from fat, try bumping up the intensity of your activity for even one or two minutes several times during your activity. Remember the most important thing to do is to challenge yourself.
    • Q.
      Do I need to get to a certain heart rate for it to count as activity?
      • A.
        Yes, however the heart rate you need to reach for an activity to count as physical activity depends on your own maximum heart rate. If you don’t know how to calculate your estimated maximum heart rate check out this resource. For light effort activities you need to be between 45 and 54% of your maximal heart rate, for moderate effort activities you need to be between 55 and 69% of your maximal heart rate and for vigorous effort activities you should be between 70 and 89% of your maximal heart rate. A good guide if you don’t know your maximum heart rate is the talk test. This means that if you can carry on a conversation easily you are working at a light effort, if you are able to talk but need to stop talking and take a deep breath every couple of sentences you are working at a moderate effort, and if you can only speak in short sentences you are probably working at a vigorous effort level.
    • Q.
      I don’t have a gym membership, but I want to start being more active. What do you suggest?
      • A.
        There are many great activities and exercises you can do that require little to no equipment and cost far less than a gym membership. Walking or jogging are great activities where all you need is a good pair of sneakers and comfortable clothes, to be ready to go out and get some endurance activity. Body weight exercises and exercise tubes can provide an excellent strengthening workout in your own home, or outside. Stretching activities don’t take any specialized equipment and can be done anywhere. There are definitely lots of activities you can do without having to go to a gym.
    • Q.
      Do I need to do a warm up and cool down?
      • A.
        A warm up is always a good idea, not only will it help you prevent injuries, it will help you to have a better workout too. For moderate effort activities you should warm up for 2-3 minutes, for vigorous effort activities 3-5 minutes and for maximal effort activities 5-7 minutes of warm up is recommended. As for a cool down, it is always a good idea to do a minimum of 3 minutes of light activity after a hard workout. It will help your body recover more quickly from your exercise so you will be ready to go the next time.
    • Q.
      I heard you shouldn’t stretch before a work out because the muscles are cold. Is that true?
      • A.
        It is true you shouldn’t stretch before an activity, but not because your muscles are cold. Static stretching, where you hold a muscle in a stretch for 20-30 sec, makes muscle relax and basically slows down the time it takes the muscle to turn on. This is not a good thing when you need your muscles to respond during activity, so static stretches should be saved for after activities. Instead try dynamic flexibility exercises such as leg swings and arm circles before an activity to get your muscles and joints warmed up and ready to move through their proper ranges of motion.
    • Q.
      How do I know how much water to drink during exercise?
      • A.
        Well you shouldn’t wait until you are thirsty to have a drink as you are probably dehydrated already. The best plan is to try and drink about 1 - 2 cups of water in the two hours before your activity and continue sipping on water throughout your workout, attempting to take in about 1 cup of water every 15-20 minutes during activity. This way you will stay hydrated and comfortable. Also note that when exercising at higher intensities or in hotter temperatures you may need more water to stay hydrated.
    • Q.
      I wear a pedometer, but I can never get close to my goal of 10 000 steps per day. Any tips?
      • A.
        It is a good idea to try and slowly bring up the number of steps you get in a day by about 500 steps every couple of days. Ways to do this include parking farther away from your destination, getting off the bus a stop or two early, fitting 10 minute brisk walks into your day, and taking the stairs whenever possible.
        If you can work three 10-minute brisk walks into your day, not only will you be meeting the recommendations in Canada’s Physical Activity Guide for endurance activities, you will be getting approximately 3500-4000 extra steps.
    • Q.
      Is walking just as good as running? (health wise and burning calories)
      • A.
        In terms of health, walking and running can provide the same benefits for your body, as long as you work at a challenging level for either activity. Running will likely require less time to reach health benefits, as you will probably be working at a higher intensity, unless you walk at a very brisk pace. As for calories burned, running will probably burn more calories in the same amount of time of walking, unless you walk at a very brisk pace.
    • Q.
      Is pain good while working out? (no pain, no gain)
      • A.
        That really depends on how you define pain. On one hand pushing yourself to have tired burning muscles that are screaming at you to stop because you are working so hard is probably okay, as you are challenging yourself. On the other hand, sharp pain especially in a joint is not a good thing. You should not do an exercise that causes pain right away or that the pain doesn’t go away when you stop the exercise. Also, if after a workout you are sore for more than 2 days, or are unable to perform your activities of daily living then you probably pushed too hard.
    • Q.
      What do I do if I get hurt?
      • A.
        After an injury from physical activity, assuming it is not something major like a broken bone or a torn ligament, then you should apply the RICE principle for the first 48 to 72 hours after it happens.
        Rest the injured area.
        Ice the injured area for at least 10-20 minutes until the area goes numb and repeat every hour you can, for at least the first forty eight hours.
        Compress the area with a tensor bandage or tight clothing if possible.
        Elevate the injured area above your heart when possible.
        All of these actions will help reduce swelling and speed up the healing process. If after 72 hours the injured area isn’t feeling much better then you may want to speak to your physician, a physiotherapist, or another allied health professional about further treatment.
    • Q.
      When is the best time for working out when I’ll burn the most calories?
      • A.
        This actually depends on you when do you feel like you have the most energy and ability to focus on challenging yourself during your workout? There is no specific time when you will burn more calories over another, if you are doing the same activity at the same pace. For some people the morning is an excellent time to exercise, for others after work or in the early evening is best. Find the time that is right for you and make sure to challenge yourself during your workout to get the most out of it.
    • Q.
      I have heard it is not good to watch TV while working out, is this true?
      • A.
        Yes, this is true. Watching TV, reading, and talking or texting on a cell phone will distract you from your workout and can cause you to exercise at a lower intensity, therefore getting less out of the time you spend at the gym. Listening to music on the other hand can be a great motivator, but you need to choose some upbeat tunes to keep you moving. During any activity it is important to focus on what you are doing so you can challenge yourself and get the most out of it.
