Challenge:  It’s ‘D’ Time!

Well, the sun seems to be shining a bit more these days, which brightens everyone’s mood as they carry on with their daily routines.  It’s amazing how much better one can feel by catching a few of the sun’s rays in their day.  We hear a lot about Vitamin D during the cooler, darker winter months, and how important it is to reach adequate levels of the vitamin.  But why?  Vitamin D stimulates the absorption of calcium, explaining why we often find milk products fortified with the vitamin.

When the body doesn’t have enough Vitamin D, it compensates by leaching calcium from our bones.  Calcium is also a precursor for the active form of Vitamin D our bodies need, when sunlight isn’t available, which is why we need to ensure we are reaching the right levels of Vitamin D.  If we don’t, our bones will become weaker as more and more calcium is taken from them, leading to issues such as rickets, in children, and osteomalacia and/or osteoporosis in adults (through long periods of inadequate D absorption).

Exposure to the sun’s rays allows our bodies to make Vitamin D, BUT, taking a small dose of Vitamin D (measured in International Units) is still ok to do during the summer months, and definately in the winter months.

So, keeping with our challenges of nutrition and fitness health, this week, I encourage you to get out and about for at least 30 minutes a day.  Go for a walk, run or rollerblade.  Take the kids and neighbours to the park and have some fun playing with a soccer ball, Frisbee, baseball or football.  Take advantage of the weather……not only for the good of your nutrition health, but for that of your physical health too!

Include food sources that provide your body with Vitamin D as well:

  • Cod liver oil
  • Cold water fish – mackerel, salmon, herring
  • Eggs (mainly the yolk) – be mindful if high cholesterol issues exist
  • Plant sources are generally lower in Vitamin D, but the best sources include dark leafy greens

Challenge:  The Right Kind of Fat!

There are 3 macronutrients we need to include in our diet providing the calories we need to function on a daily basis, as well as essential nutrients to keep our bodies healthy and organs running at their optimal levels: Carbohydrates, Protein and Fat.  We know that we should be including more complex carbohydrates from whole grains, fruits and vegetables, protein from lean meat sources, lower fat dairy products, legumes and tofu, and fat from…….where?  Fat is an important macronutrient we need in our daily diets, aiming to consume 20-35% of our daily caloric intake from this particular macronutrient.  The take home message ALWAYS when it relates to fat is consuming the right types of fat in the correct portion.

It is mandatory for food labels to include the amount of total fat found in a particular portion of a product, as well as the saturated and trans fat content of that product.  Most often, when a certain product offers a number of healthy benefits, you may also see the polyunsaturated and monounsaturated fat content of the product listed.  So, what should we be looking for, and what should we be staying away from?

The types of fat we include in our diet determine how well our blood flows through the vessels.  Our body’s membranes are made mostly of fat —-cholesterol, trigylcerides, phospholipids.  Though our body is capable of making these fats (and needs to for some processes to occur), the type of fat YOU EAT mainly determines the type of fat that makes up your membranes, and thus, how well your blood flows.  For example, if we eat a diet high in saturated and trans fats (BAD FATS), plaque builds up along our artery walls, increasing bad cholesterol and triglyceride levels, ultimately making it very difficult for our blood to flow through normally.  On the other side, if our primary fat intake throughout the day comes from poly- and monounsaturated sources, these healthy fats help to decrease bad cholesterol levels, preventing plaque from building up against the artery walls, and therefore, allowing our blood to flow normally to all organs of the body so that they all function properly. 

So, this week’s challenge is two-fold: 

  1. Look at the ingredient lists of the food items you choose to include in your diet this week, making sure that the combined saturated and trans fat content does not exceed more than 10% (**review “What’s in a Label” located under the Nutrition tab), or better yet, none to minimal levels of these fat sources
  2. Include sources of healthy omega-3 fats in your diet, being mindful of the portion:
  • 1 tbsp Extra Virgin Olive Oil
  • ¼ C unsalted nuts and seeds – almonds, walnuts, pecans, cashews, pumpkin seeds, sunflower seeds
  • ¼ of an avocado – slice it in a sandwich, top off a salad, mix with an egg for a spin on the classic “egg salad sandwich”
  • 4-5 oz of cold water fish – salmon, mackerel, halibut
  • 1 tbsp ground flaxseed – on toast with peanut butter, in yogurt, in your favourite tomato sauce
  • Cook with canola oil more often
  • Switch to margarine including EPA and DHA

Fat provides more calories in our diet (9 calories/gram of fat), so though we need to include the proper poly- and monounsaturated food sources, we must be even more mindful of the individual portion sizes, just like in everything we eat!

Challenge:  April Showers Bring May Flowers!

A new month! A new challenge! And a new food for thought!  There may be a bit of excitement as we begin to notice the different colours taking over the flower beds in our front or back yard, by entry-ways or even sporadically along the roads!  But what about the different edible “flowers” we are encouraged to consume, that bring a variety of nutrients to our bodies?  In particular, the Brassica family of vegetables, including broccoli, cauliflower, arugula, Brussel sprouts, cabbage, mustard and kale.  It is encouraged that we consume these types of “flowers” in our daily diets, as a source Vitamin A, Vitamin C, Vitamin K, folic acid, fibre, iron and calcium, just to name a few.  Just how flowers bring a colourful arrangement to any picture, “flower” vegetables do the same to our meal-time plates!  You can even find purple, orange or yellow cauliflower these days, or red and purple kale!  So, when preparing your meals, I encourage you to base your meal around a vegetable.  Choose a new vegetable! Look on the web to see the endless possibilities available to you on how to dress a vegetable in a new way, or season it with a drop of Extra Virgin Olive Oil and your favourite fresh herbs!

Make a hearty arugula salad with sliced strawberries, goat cheese, almonds and grilled chicken! Try steamed broccoli with shredded light cheddar cheese alongside a piece of salmon and rice, or raw broccoli dipped in hummus as a snack!  Pasta dish?  Cook half the amount of pasta and add in kale to heighten the nutrient profile of your dish, as well as some peas and corn to bring a bit of sweetness to the dish!  Steer away from your traditional lettuce salad and try a cabbage salad topped with light feta cheese and pecans and dressed with a mix of apple cider vinegar, oil, honey, garlic and onion!

Seven days of the week! And seven days until you receive your next challenge! So keep your meals interesting this week, choosing a different “flower” to colour your plate, and different variations to enjoy your dish or meal!  Your palate may take on the new flavours in a way you never knew you would, bringing you back for more in the days to come!
