What I think of the new Canada’s Food Guide

To be perfectly honest, I rarely pulled out the old rainbow Food Guide when talking to my patients. If you don’t remember the old guide, it was a rainbow representing the 4 different food groups which were arranged in order of foods you needed the most servings from to the least. The main focus of the diet was on vegetables and fruit, followed by whole grains, milk and alternatives and finally the food group you needed the least servings of was meat and alternatives. From there they gave guidelines such as eat more vegetables than fruit, eat at least half your grains as whole grains, choose beans and lentils often etc. They then prescribed a number of servings for each food group based on age and gender.

The reason I didn’t use the guide was because it was meant to be an education tool to learn about different food groups and their purpose rather than provide practical steps to get someone to follow the prescribed servings.  Plus, people generally know the focus of their diet should be on vegetables and fruit but this needed to be more visual, practical and user friendly. For these reasons I found easier and more effective ways to communicate the information in the guide in my own way, not to mention nutrition is not a one-size fits all and therefore did not use the guide in my practice.

The New Guide

The new Canada’s Food Guide encompasses many important aspects of eating and also provides consumers with more specific guidelines about foods to choose more or less often in a very visual way. There has been a lot of hype about the new food guide, both good and bad (like everything… everyone has their own opinion!). I honestly think that the information has not changed, rather how it has been communicated has.  These changes in communication have been extremely positive.  The new Food Guide is very similar to values that guide my counselling style and advice.

The visual of the plate, with half the plate covered in a variety of deep colourful vegetables and fruit, a quarter of your plate as your whole, unprocessed grains and starches and a quarter of your plate as your plant or animal protein sources. This communicates very easily and simply how you want your plate to look compared to the prescription like recommended servings of the past Food Guide. The new guide still promotes the same values as before: eat real foods, include lentils and plant proteins, lean proteins, whole grain carbohydrates and more vegetables, with less sodium, saturated fats, processed foods and sugar. All of these values line up with my own personal beliefs and what the evidence shows.

There are a few things I really like about the new guidelines. It is more interactive and web-based rather than a physical pamphlet which may be better for our tech-savvy population. Not only is the visual of the plate very easy to see, understand and apply, but it also acknowledges the social aspect of food and promotes building a healthy relationship with food. This is also a foundational value of Bodzii (personalized nutrition and lifestyle coaching), where we think it is important to have both good food quality and a good food mentality. For example, viewing food in a positive light such as thinking of what a food can do for you, not to you. There is a wide range of information for consumers on practical ways to be mindful of your eating habits, benefits of cooking more often, ways to enjoy your food, benefits of when you eat meals with others, how to use food labels, and how to be aware of food marketing along with much more.

What about the dairy? Everyone is freaking out that dairy is no longer a “food group”. One thing I think the Food Guide needed to do was separate themselves from organizations and give an unbiased, easy to use guide for consumers in which takes “food politics” or influences out of the equation. Dairy is still in the guide, just as the other food groups such as grains and meat and vegetables are. However, there is a shift from food groups to a “macronutrient” like approach. This means that the dairy products are now represented in the protein portion of the plate. This DOES NOT mean that milk is considered unhealthy. As always, milk (soy, pea and cow milk) still provides us with protein, vitamin D and calcium for strong bones, teeth and muscle function.

Overall, the new changes to the Canada’s Food Guide are more in line with I have been teaching and promoting all along. The guide may not satisfy everyone depending on what “nutrition camp” you belong to such as keto, paleo or even elite athletes. It is not meant to be a one size fits all model, rather what the best evidence shows a balanced diet looks like for a healthy normal human. The bottom line is to not over complicate your nutrition. Focus on getting your vegetables, whole grains and lean proteins to meet your needs. Also remember to find ways to enjoy your food and to be mindful of what and how you eat along with striving to enjoy home cooked meals when possible.

I hope this helps to clear up some confusion you may have been experiencing with regards to this new guide.  If you have any additional questions, don’t be afraid to contact me at the clinic!

Oh hey, I’m back! It’s been a while. My hiatus from writing didn’t coincide with a break from reading though, and I have accumulated a number of tidbits and interesting thoughts on training and performance to bring to you in 2019!  No promises on the frequency of the articles, but I shall do my best.

Today, we’re starting with one we all need to know about: the warmup.

It’s something I’ve written about before- both in terms of cool additions that you really shouldn’t implement (such as here), how a warmup doesn’t literally mean warming up and what we’re actually after (glycogen mobilization and increase in blood flow to our running muscles), and even how it relates to carbohydrate ingestion (here).

Warmup Duration

One thing I get asked about often enough at H+P is why my warmup protocols vary so drastically from distance to distance. For instance, for 5K and under, the warmup is longer with drills. For the marathon, the warmup is just long enough to make sure your shoes won’t come untied and to keep the mind relaxed.

Our clinic had a great time at the 2018 Fall 5K Classic!  We had a huge group of runners out with our learn to run group who started from ground zero going all the way to running their first 5K ever (or at least first 5K in a long time).

It was amazing to see all of our teammates cross the finish line with a mix of smiles and exhaustion on their faces!  Running a race for a beginner can be super daunting and intimidating task, but this crew banded together and conquered the challenge with hard work and positive attitudes from start-finish.  For those who signed up with the team, our crew ended up averaging a very impressive time of 29:59!   Not all of you appeared on this list for various reasons, sorry about that!  Check out the full results HERE.

Version 3

In general, our society is becoming more health conscious, which is great! People are living longer and are looking to feel younger as they age. I often work with aging athletes, and older adults to help provide guidance on how they can use different nutrition strategies to help them reach their goals, whether health or fitness related. One of the most common issue these I find older adults face including recovery, strength and body composition changes. If you are over 50 I would encourage you to keep reading!

Sarcopenia

Sarcopinia is the term used to describe the gradual muscle mass loss seen in older adults. We know that in general once you hit age 50, you start to lose about 1% of your lean body mass per year. This is concerning for a few reasons. First, the loss of muscle mass means you will also likely lose functionality, ie you may be unable to lift groceries like you used to. It also can result in changes in balance and stability which may lead to increased risk of falls. Lastly, because our muscle mass is a metabolically active tissue (ie it stores and burns carbohydrates and fats) the decreased muscle mass can decrease the metabolic efficiency and storage of carbohydrates and fats and can lead to development of chronic diseases such as cardiovascular disease or type 2 diabetes. This results in a huge stress on our health care system and therefore is important for us to think about nutrition strategies to maintain our muscle mass as we age.

Why do we lose muscle mass?

It is not known for certain why we lose muscle mass as we age, whether we have a general decreased muscle building and/or increased muscle breakdown or a lower sensitivity for turning on protein synthesis (ie it takes more protein to increase muscle building). Either way, in general this leads us to have higher muscle breakdown than build up, and thus a loss of lean tissue.

What can we do about it?

The first point I want to make is not related to nutrition. It is well known that resistance training is a VERY powerful stimulus of muscle building capacity and aged muscles respond to resistance training similar to young muscles. Resistance training in combination with very easy nutrition changes can help retain, maintain and possibly even build muscle mass in older adults.

 Nutrition Strategies

  1. Increase the protein intake

In a westernized country like Canada, we often get enough protein, however I do notice that older athletes or adults may still need to bump up their intake to maximize recovery. The reason for this recommendation is because we know that an older adult will not respond to a 20g dose of protein like a younger person would, and a higher dose of protein is needed to stimulate muscle building. Some older adults experience decreased appetite and will reduce portions, again we need to keep in mind we need more protein to maintain our muscle mass compared to when we were young!

  1. Protein quality is important

Research does show that soy protein vs whey or beef protein is less effective to stimulate muscle building. Even though soy is a complete protein (has the same amino acid make up as meat) it seems as though it is processed slightly different in the body. Mainly, the protein in soy seems to be digested slower resulting in less of an increase in amino acid levels in the blood and thus decreased stimulation of muscle protein synthesis. Very careful nutrition planning is necessary if you are an older adult who adheres to a vegetarian or vegan diet.

  1. Dairy

Dairy has the amino acid Leucine, which is a branch chain amino acid. It is a potent stimulator of muscle synthesis and can assist in maintaining lean mass. Not only is dairy a source of leucine, but adding a glass of milk to your meal will add about 8g of protein, which actually could be all the changes you need to make to meet the protein needs at your breakfast, lunch and dinner. In addition, consuming dairy products will provide you with calcium and vitamin D to assist in prevention of osteoporosis! Win win right?!

  1. Distribution

We talked about the amount, quality and now we get to the timing! If we look at typical protein amounts at each meal of the general population, we typically consume very little protein at breakfast, moderate amounts at lunch and a HUGE portion at dinner. This is a very skewed distribution of your protein and very little protein synthesis occurs until the dinner time, where not all of that protein can even be used and is wasted. Having multiple doses throughout the day at regular time intervals is the best method of feeding and maintain your muscle mass. You also want to make sure you place your protein at appropriate times to ensure adequate recovery from exercise bouts.

  1. Supplements

If you are an older adult who is engaging in regular exercise, supplements like protein powder might be common place in your dietary plan. One other supplement that has been shown to have some benefits for older adults is creatine. First we must understand that lifting a weight for 8reps the activity is more intense and it lasts very little time and therefore it will use anaerobic metabolism for the most part, which means that you will be using the phosphocreatine pathway to provide energy along with carbohydrates. The theory is that the more creatine in the muscle, the harder you can train, thus getting a better workout and getting a larger response of muscle strength and growth. It can be used to stimulate your muscle building potential. Research does show that proper dietary strategies + weight training + creatine supplementation can result in additional muscle building, increased strength and also increase in functional movement. Proper dosing is needed to elicit results, and there are a few contraindications for using such a supplement, independent assessment for this supplementation is needed.

As our population ages, it is predicted that at year 2050 a quarter (25%) of the population will be over the age of 65. This may put strain on our health care system, and therefore we need to make sure we do as much as we can to keep our bodies healthy as we age.

Version 3

We are back at it again, and this time I want to talk a little bit about nutrition concerns for the male endurance athlete. If you have been following along with my previous blogs (if you haven’t, you should be!), you will recall we discussed how nutrition impacts the health and wellbeing of female endurance athletes, especially regarding stress fracture risk. You can find it here, if you would like to take a look back for a refresher.

For a quick recap, we discussed how endurance running is a huge metabolic demand, meaning it costs a lot to run fast for long periods of time. This can result in accidental under consumption of macronutrients (carbohydrates, fat and protein), energy, and ultimately vitamin/mineral intake, or purposeful restriction of food intake to achieve a desired level of thinness or body shape. Chronic under consumption, whether accidental or not, of both nutrient and energy, can cause some physiological changes in the body and can greatly increase your risk of bone related injuries.

It was typically believed that low energy availability (LEA), in the past known as the female athlete triad, only was a complication females encountered in sport, however it is now known that males also experience negative health and performance effects of LEA. It is possibly harder to detect in males, as there is no clear sign, such as loss of menstrual cycle, however that is why we need to be careful not to miss the subtle signs. In this article we will discuss what happens physiologically with LEA, and its effects on bone mineral density (BMD).

Physiological Changes
Under consuming energy can be a difficult concept to understand because calculations of exercise energy expenditure, basil metabolic rate and even energy intake are difficult to assess. Current research defines “Energy Availability” (EA) as the left over energy to be used for normal physiological processes after accounting for energy expenditure, which is expressed as kcal/kg of FAT FREE mass.

The EA equation= [energy intake- exercise energy expenditure] / fat free mass (kg)

Physiological Changes With LEA
– Decreased metabolic rate
– Increased cortisol (stress hormone)
– Decreased testosterone
– Signs include fatigue and decreased sex drive

Bone Mineral Density
There is ample evidence to suggest that an active individual have higher BMD than sedentary individuals. Within the athletic population swimmers and cyclists tend to have fairly low BMD due to non-weight bearing nature of the exercise. A study by Viner et al. looked at male and female cyclists with lower than expected BMD. The found that 70% had LEA across the entire training cycle, including pre season, competition and post season. This points to the theory that this particular group may have had low BMD due to their LEA. They found that 40% of the participants had low bone mineral density in their lumbar spine, and 10% had low bone mineral density in the femoral neck. The athletes were followed for 1 year and their BMD stayed the same, which is positive. The researchers pointed to their previous interventions of increasing vitamin D & calcium intake and including weight training as a reason for the maintenance of BMD. This provides evidence that a good nutrition and training intervention can help maintain bone strength.

Another study in elite male endurance athletes showed that LEA resulted in low testosterone (although not clinically low) however it did not result in any differences in BMD compared to those with normal testosterone levels. There seems to be a caloric value threshold before we start to see negative health and bone effects. Interestingly, it seems as though women are more sensitive to changes in EA, where we see significant and detrimental effects in heath and bone when their EA reaches 30 kcal/kgFFM/day or below. There is evidence that this occurs at levels of 20-25 kcal/kgFFM/day in a male athlete, although more research is needed to confirm this. This study suggested that because they investigated athletes at ~30kcal/kgFFM/day that this was not enough of a deficit to result in decreased BMD. However, this does not mean you can neglect your nutrition planning because even though their BMD did not change, those with low testosterone had 4.5x more risk of sustaining a stress fracture and had 4.5x more missed training days due to injury.

Main Take-Away:
In elite endurance athletes, 40% of males were found to have LEA. Even temporary low EA increases bone breakdown and decreases bone building, and chronic low EA has long lasting effects on bone health plus many more effects such as mental health and performance to name a few. Therefore, it is essential to stay on top of your nutrition as a part of stress fracture/injury risk reduction.

1. Negative energy balance and testosterone: studies show low testosterone results in 4.5x higher risk of bone injury and had 4.5x more missed training days due to injury
2. NFL players and vitamin D: In NFL players, low circulating vitamin D levels correlated with increased risk of core and lower muscle injuries; players with 1+ fractures had higher rates of inadequate levels of circulating vitamin D.
3. Military recruits with lower serum Vitamin D- correlated with higher risk of fractures

keto 1

If you have been following along in my past articles, you saw the evidence for whether or not a keto diet is beneficial for endurance athletes. However, I wanted to also share my thoughts and some research on the keto diet for my non-athlete readers. In this article I will discuss why keto may, or may not, be a good choice for you.

 First off, I want to say that keto is likely not meant to be a life-time eating style.

Typically for weight loss, keto could be used for 2-4 months and then one could switch into a long term maintenance phase where you are including healthy carbohydrates.

Secondly there are some warnings that come with the keto diet. Our brains and hearts run exclusively on carbohydrates and when we severely restrict carbs, our body needs to switch to the use of ketones for fuel instead. There is a 3-4 day period of “brain fog” when you initially switch to a keto diet, where your ability to think is reduced. Not to mention food selection is quite limited and your social life may take a hit due to your restrictions. Plus, fair warning, your breath will smell bad too!

There are risks!

Very close monitoring is required for implementing a keto diet (especially to assess if keto would be a benefit to you). You also have to have a solid plan for transitioning into a regular diet, which should also be lead by a dietitian or qualified health care professional. The latter is quite important. This is because when you starve yourself of carbohydrates and then suddenly reintroduce a large load of carbohydrates, the body switches to an anabolic (or build up) mode and causes increased insulin, increased uptake of carbohydrates into the cells, increased utilization of those carbohydrates, all which increases the uptake and use of potassium, magnesium, phosphate, thiamine and increased sodium and water retention. The sudden changes in these electrolytes and vitamins can cause serious issues that can be as severe as a heart attack. AKA you can not have a cheat day in a keto diet and have yourself a big old piece of cake.

Keto & weight loss

Most of the research as a whole shows that you MAY lose more weight on a keto diet vs. regular diet.  However, when studies include body composition analysis they show that on average keto leads to more overall weight loss, but the amount of fat lost is the same. This means that keto diets lead to more muscle mass loss compared to a traditional diet.

Therefore, you may see a better outcome when you step on the scale but it may have less desirable body composition changes.

 The main reason for this finding is that you have to have a moderate protein intake while on a keto diet because protein can be used in a process called gluconeogenesis, where amino acids are (inefficiently) used to make glucose, thus keeping you out of ketosis, where as a traditional weight loss diet will be higher in protein to support the muscle mass retention. Other reasons could also include you can not have dairy, which has been shown to be an important food group to stimulate weight loss and muscle mass retention due to its leucine content.

It is also important to note that resistance exercise is a VERY powerful stimulus of muscle protein synthesis and muscle retention during weight loss, and regardless of diet should be included in your weight loss plan.

There may be benefits too

Keto may work for certain people. For instance, people who are on a keto diet often feel more satisfied with their diets. This is likely because higher fat foods are often pleasurable foods and provide flavour and mouth-feel to food (ie cheese, who doesn’t want to eat a brick of cheese every day!). Johnstone et al. (2008) conducted a study where participants were able to eat ad libitum (ie no restrictions or standards for caloric consumption) and participants were assigned to a keto group or a moderate carbohydrate group. They found that people on a keto diet felt less hungry, and lead to them eating less than compared to a moderate carbohydrate diet.

To my surprise, keto does seem to have a beneficial effect on decreasing blood glucose and HbA1c levels, decrease triglyceride levels, LDL cholesterol, and may increase HDL cholesterol levels. One thing I think is important to remember here is that in most cases, healthy dietary changes (ie more vegetables, fibre, less processed carbohydrates and sweets etc.), decreasing alcohol consumption, and increasing exercise can do the same for you, without doing something as intense or dramatic as a keto diet.

 Take home:

My personal and professional opinion on this is that I would first have someone try a to make healthy diet changes which would include consuming good sources of carbohydrates such as beans, lentils and whole grains before trying a keto diet. Keto in my mind is a last ditch effort if no other dietary interventions have worked.

Summary:

  • Keto diets can be somewhat dangerous and should be eased into and out of with the help of a qualified health care professional
  • Keto diets sometimes result in more weight loss but fat loss is comparable to typical diet
  • There must be a caloric restriction to create weight loss, no different than a regular diet
  • Keto may help keep you full and more satisfied with the diet and may help you adhere to the diet plan
  • Keto does seem to have beneficial therapeutic effects for type 2 diabetes, pre-diabetes and on blood lipid profiles (but so does healthy diet/exercise)
  • Ultimately the diet needs to be something you can follow and stick to before transitioning to your maintenance phase, if that’s keto, great!
  • Bottom line: Try traditional approaches first, if that is not successful, you could consider the keto diet for the short term and transition into a healthy diet intervention for maintenance

I hope you found this helpful, this is not a full list of keto uses and I did not list all the pros and cons for you, as I wanted to keep this conversation relatively short. If you have any further questions about dietary interventions for building a healthier you, please feel free to come in for a visit. To learn more about me, you can find my bio here.

We’ve all heard of DOMS (delayed onset muscle soreness) and the majority of us have experienced it at least once.

It’s that muscle pain and weakness that we feel a day or two after some exercise. It can be caused by any type of muscle contraction but it is most commonly caused by an eccentric exercise such as downhill running and resistance training. (Reminder: an eccentric exercise is a movement where the muscle is under load as it lengthens. For example, a raising part of a bicep curl is a concentric exercise but the lowering part of a bicep curl is the eccentric part)

The typical symptoms include strength loss, pain, muscle tenderness, stiffness and swelling. Symptoms typically peak 24-48 hours after exercise and fade within 96 hours. The severity of DOMS depends on several factors but in general, more damage occurs with higher intensity and unfamiliar actions.

Physiologists do not have clear understanding of the mechanism behind DOMS, however the proposed theory involves a mechanical disruption to the sarcomeres (the fundamental unit of a muscle structure) which then sets off an inflammatory response. The swelling is caused from the movement of cells and fluid from the blood stream to the muscle, where it contributes to the sensation of pain.

I’ve often been asked if it’s okay to continue exercising and/or what can someone do to help reduce the feeling of DOMS. A recent meta-analysis looked to compare the effects of the most commonly used recovery techniques on muscle damage, DOMS, inflammation and the feeling of fatigue from physical exercise. The authors looked at the effects of 1 session of several different types of recovery techniques after physical exercise on:

  • DOMS
  • Perceived fatigue (ie: how much someone feels tired)
  • Inflammatory markers (IL-6, CRP)
  • Muscle damage markers (CK – creatine kinase)

Let’s have a look at the evidence!

Massage

Based on this meta-analysis, massage was the most effective for DOMS and perceived fatigue! The authors reported that a 20-30 min massage performed immediately after or up to 2 hours after exercise has been shown to help reduce DOMS for 24-96 hours after exercise. Elite athletes (in this case ultra-marathon runners) reported a significant improvement in lower perceived pain after massage. Not only does a massage feel good, but it has also been shown to reduce CK and IL-6 in the blood after exercise which may help towards a faster recovery.

Rationale:

Massage seems to help the symptoms of exercise-induced muscle damage by increasing blood and lymph flow which can stop the CK response and clear it from the blood. It’s assumed that massage flushes out neutrophils (an immune cell that responds to inflammation) from the damaged area which would otherwise cause more CK in the area.

Compression Garments

Compression garments have a significant and positive impact on DOMS up to 96 hours after exercise. It has been shown that wearing a whole-body compression garment over a 24-h period after intense heavy resistance training significantly reduces perceived fatigue. That might not be realistic for us but other compression garments such as leggings and socks can be used.36391146502_1bd4d6090e_k (2)

Rationale:

The beneficial effect of compression garments might be explained by:

  • A reduction in the space available for swelling and edema
  • Better venous return (blood flow back to the hear)

Cold Water Immersion

Cold water immersion (CWI), aka: ice baths, showed a significant effect on DOMS and perceived fatigue after training and competitions/tournaments as well as after strenuous exercise in both trained athletes and recreational subjects.

Ice baths in water at 11-15⁰C for 11-15 minutes is considered the optimal dose to have a positive impact and reduce DOMS.

Rationale:

CWI seems to help reduce exercise-induced inflammation, edema, pain sensation, and muscle damage through these ways:

  • The hydrostatic pressure from being immersed in water may help transport fluids from the muscle to the blood and therefore eliminate inflammatory products
  • Narrowing of blood vessels from the cold temperature may reduce fluid diffusion into space in the muscle and reduce the inflammatory reaction

Contrast Water Therapy

Contrast Water Therapy (CWT) which is bathing alternately in warm and cold water seems to have a small effect on DOMS but not perceived fatigue. CWT has been able to reduce the perception of pain at 24, 48, and 72 hours post-eccentric exercise. CWT also reduced CK concentrations in the blood.

Rationale:

CWT promotes the opening and narrowing opening of blood vessels which may reduce the formation of edema, inflammatory pathways and decrease feeling of pain.

Active Recovery

Active recovery also has a significant effect on DOMS, but not effect on perceived fatigue however, the impact of active recovery is only significant during a short period after exercise. There seems to be no influence of active recovery on CK, IL-6 and CRP concentrations in the blood.

Rationale:

Active recovery seems to help DOMS by enhancing blood flow in muscle tissue, which helps to remove metabolic waste and therefore reduce muscle pain.

Cryotherapy

Cryotherapy is the exposure to a cold chamber and appears to be effective in reducing DOMS after exercise. The authors found that cryotherapy had an effect on DOMS but only for about up to 6 hours after exercise and any cryotherapy done 24 hours after the end of exercise is ineffective in alleviating DOMS.

Stretching/Electrostimulation

The meta-analysis did not find any significant influence of stretching or electrostimulation on DOMS and fatigue. In fact, results showed that stretching less than 6 hours after exercise might even produce DOMS.

Take Home Points!

At some point we will experience DOMS and with time, it will go away on its own but there are some ways to help reduce the feeling and possibly recover faster. Massage seems to be the most effective in relieving DOMS and fatigue. Ice baths and compression garments can also help but are less effective.

Keep in mind that the outcomes from this meta-analysis looked at many studies with different protocols and the results can vary depending on many things such as the type of exercise, level of immersion in water, and amount of pressure from compression garments to name a few.

One final note is that while research shows that these post-workout techniques can make us feel better faster, over time we might we lose some of the benefit from that hard workout or training session since the signal to adapt to the training is blunted from using these recovery methods. So, it is important to use them strategically (ie: after a race where you went too hard or leading into a big race) and to avoid using them during base training and instead just give yourself more time to recover.

Hope this helps with your recovery!  If you have any other questions, or would like to learn more about me, check out my profile HERE.
