A Dietitian's Guide to Conscious Eating
Part 1 - Eggs
When we take a look at how food production has changed over time, it is apparent how our diets have changed along with it. A growing population over the last 100 years, almost quadrupled to be precise, has created a demand for a more convenient and less labour-intensive method of producing our food. We have seen farms transition from small- and medium-sized to massive industrial-sized farms, operating with the goal to produce, maintain, and slaughter animals as efficiently and inexpensively as possible. Agricultural farms can attest to many reasons for their ability to produce more grain on fewer acres with fewer nutrient inputs. And since the end of World War 2, we have seen a dramatic rise in a different kind of processing, wherein refined sugars, additives, preservatives, and a whole whack of unpronounceable ingredients hit our diets. Despite these changes, with keen interest, a little homework, and of course the most precious commodity, time, it is possible to purchase and provide your family with ethically raised, organic, and nutritious food. Based on the available evidence, and deep-seated from my own experience and perspective, the following is the first of a 4 part series
that explores the many different avenues we have in choosing healthy, sustainable food.
The proverbial saying “you are what you eat” is repeatedly proven to be true. If you fill your diet with healthy and nutritious food, you will likely be rewarded with many health benefits. However, the saying also can be applied to our food’s
food. Having a keen interest in preparing food for my family, it goes without saying that where my food comes from is essential. This would be the case for eggs, poultry, beef and pork, fish, oils, vegetables and fruit, and legumes/ grains/ snack foods.
The egg has been coined the perfect food.
First off, let’s get things straight regarding what’s in the grocery store when buying eggs. According to an article compiled by Sunny Brower, Jillian Dorsey, Kate Malvetti and Julie M. Fagan, Ph.D., the five main options people have when purchasing eggs are conventional, cage-free, free-range, organic and pasture-raised.
Conventional eggs:
The eggs purchased at supermarkets that do not have labels or have supermarket store brands are known as conventional eggs. Conventional hens beaks are clipped, which is done so hens won’t peck at themselves or other hens and hurt themselves, rendering antibiotic treatment, and are treated extremely poorly. The average battery cage allows the hen less than half a square foot, which equates to about 67-76 square inches, which is nearly 25 square inches smaller
than a legal size piece of paper
(Humane Society, 2013). Laying hens spend about 95 percent of their lives in these cages, which restricts the hen from spreading its wings and most other natural movements. These conventional hens are housed in these battery cages inside windowless warehouses with some containing as many as 100,000 caged chickens at a time. The conventionally farmed birds never see sunlight and are fed a diet of corn waste and chemicals, with a sub-therapeutic level of antibiotics present in the chicken feed. Over 90% of Canada’s laying hens are kept in cages (BC/SPCA Dec. 2017). Conventional eggs run about $3.50 a dozen.
A “cage-free” or “free-run” egg:
When you purchase cage-free/ free-run eggs, you know that the hens are not kept confined in cages and can engage in many of their natural behaviours like walking, laying eggs, and opening their wings. However, beak cutting is permitted in this case, and it doesn’t mean the birds are free to go outside. Free-run hens may wander inside the barn but there are no set guidelines for them to go outside. In addition, roaming inside the barn may be crowded. For cage-free eggs, there is no third-party auditing system to ensure that these standards are upheld; producers go by the honour system. Farmers are under pressure to shift this type of housing, as more companies promise to provide eggs from hens that don’t live in cages. Free-run eggs are approximately $5.99 per dozen.
A “free-range” egg:
Free-range eggs are defined by the hen having access to the outdoors. This does not mean the outdoor space is large enough for the hens, or that the hens ever went outside, especially in the winter months in Canada. Most free-range hens are housed inside barns without cages. During a free-range hen’s life, it has outdoor access, but no requirements or standards have been put into place to enforce any length of time outdoors or the quality of the land to which the bird has access. Since they are not caged, they can engage in many natural behaviours such as nesting and foraging. Free-range eggs are between $6 - $6.50 per dozen.
For both “free run”
and “free-range”
birds, no restrictions have been put into place for what they can be fed. Both types of birds appear on their product packaging to be the better options, but their diets are not government regulated. Both types of hens are also subjected to beak cutting. As such, a sub-therapeutic level of antibiotics and other regulated additives would still be present in the chicken feed.
Organic eggs:
Eggs from organically raised chickens are considered free-range and are allowed outside when the weather is nice, but are kept indoors or under shelter when the weather isn’t favourable. If a farm attains an organic certification, an auditor will visit the farm usually once a year to ensure all standards are being followed. The hens are also antibiotic-free and raised on organic feed. Keep in mind that most organic eggs are still mass-produced and whether the chicken goes outside to eat is up to the discretion of the farmer. For example, Kirkland organic eggs come from hens fed organic feed but are raised in a factory farm environment with literally thousands of birds who may or may not go outside. There are exceptions to this, however, as smaller family-run organic farms typically produce eggs from 200-500 hens that do get outside to roam free. Organic eggs are around $6.49 per dozen
in most grocery stores. Family-run organic farm eggs will cost a bit more.
Pasture-raised eggs:
Pasture-raised hens and organically-raised hens are not the same. Organic hens are fed organic, pesticide-free feed, but in most cases are raised in factory conditions. Pastured hens are not fed organic feed but get to go outside and eat as a natural chicken would. In general, pasture-raised chickens are smaller flocks of poultry in portable hen houses where the farmers rotate in fresh pasture, often-times daily.
These chickens are free to eat plants and insects, which is their natural food, along with some commercial feed. Research has shown that hens that have access to the outdoors and who eat insects and plants produce eggs that have significantly higher levels of omega 3 fatty acids, vitamin D and E, and protein; four very important nutrients!!
Pasture-raised eggs
sell for approximately $7.50 per dozen
at Mary Lous’s Market and Goodness Me, or if you’re fortunate enough, you can find pasture-raised eggs from a small farm from around your neighbourhood.
Do more expensive eggs (free-range, organic, and pastured) offer a more nutritious egg?
A marketplace special on CBC had experts do experiments to compare the nutrient profile in eggs of many large-scale egg companies. They reported that there were no notable differences in vitamins A, D, and E, cholesterol, and protein
between organic and conventional eggs. They did, however, report that organic eggs do have double the amount of omega 3’s
than conventional eggs. And additionally that pasture-raised hens and small family-run organic farmed eggs do
offer a higher nutrient profile, justifying their increased cost. Besides nutrition, conscientious consumers are prepared to pay more for their eggs knowing the chicken feed is pesticide- and GMO-free and that the farmers support the humane treatment of animals.
Key nutrients found in eggs:
Eggs are a very good source of protein
as the ratio of amino acids in an egg are at ideal levels for the human body’s protein digestion, assimilation, and metabolism.
Eggs with a higher content of omega-3's
come from hens that are pastured and organically fed. Regular brands will usually advertise omega-3 on their labels (which means the content is a little higher but not by much). The amount of omega-3 varies amongst brands. While these eggs may be higher in omega-3 than a conventional egg, do not rely on eggs to be your main source of this fatty acid. Omega-3-enriched or organic eggs have approximately 0.125 g of omega-3 per egg. The recommended adult intake of omega-3’s is 1.1 - 1.6 g per day. Optimal sources of omega-3’s are fatty fishes; a 3 oz portion of salmon, herring, or mackerel, containing more than 1.5 g of omega-3. Getting additional omega-3’s from your eggs is considered a BONUS! (seafoodhealthfacts.org; scientificamerican.com)
Vitamin D
is found in egg yolk in a fairly small quantity: 37 IU (international units) per egg. The Canadian recommended adult vitamin D intake is 600 - 1000 IU per day
with a safe upper limit of 4000 IU, and if you don’t get much sunlight, aim for upwards of 2000 IU daily. Vitamin D content in eggs is dependent on the hens exposure to sun (the more the better) so we can assume then that hens who roam outside get more sun and thus produce eggs with more vitamin D. The hens feed also dictates the amount of Vitamin D an egg will contain.
At the end of the day, your choice will be determined by availability of the product, convenience for you to purchase it, the price, and your level of interest in treatment of the animal. Apart from pastured eggs from hens on small farms, there does not seem to be a whole lot of difference in nutrients between organic and conventional eggs, however organic eggs do not contain pesticides/ GMO's or antibiotics. If you eat a lot of eggs, It is worth exploring your egg farmers to find out what your hens are eating and how they live. I can’t help but applaud and support the farmers that make a living producing eggs with a higher nutrient profile from hens who are free to roam their natural environment. There is a reason these eggs are $3-4.50 more per dozen, and to me, it's worth the difference.

Are you struggling to stay consistent with your fitness and nutritional goals? Being consistent is crucial to making long term lifestyle changes, but it is one of the biggest challenges we all face. Here are 5 strategies to help you find consistency: 1. BE REALISTIC Change takes time . There is no fast way to make lifestyle changes, so it’s imperative to make goals that make sense for you. The more attainable and realistic the goal, the more likely the goal can be accomplished. When goals and milestones are accomplished, it gives you a sense of reward and enhances your self-efficacy (i.e., the belief that you can accomplish your goals). On the other hand, if the goal we have set in place for ourselves is too difficult, it may lead to demotivation and lower self-esteem. If you want sustainable and lasting results, being realistic is the first step. 2. HAVE CLEAR GOALS Not having clear goals is like driving to a new destination without a map. Goals are important in leading us in the right direction. Goals provide you with the motivation to push yourself to work towards chane. Implementing S.M.A.R.T goals is a good place to start. S - Specific M - Measurable A - Attainable R - Relevant T - Time-Bound When setting goals, make sure to include both short term and long term goals . Short term goals help with commitment and determination by allowing you to celebrate small wins more frequently that contribute to the bigger goal in place. Long term goals give you something to focus on and strive for in the bigger picture and help focus on where you want to be in relation to where you are now. For example, you decide that you want to “Lose 5 lbs in 6 weeks.” This goal is specific, measurable, attainable, relevant, and time-bound. However, this creates the need to make smaller goals to help you get there. Just doing what you are now, unchanged, will likely not get you to your goal. For instance, you might state that you will “Lose 5lb in 6 weeks” by incorporating 1-2 servings of vegetables into every meal, by limiting take-out meals to once per week, exercising for 45 minutes 3 times per week, and going for a 30-minute walk with your dog every day. If you achieve these smaller rules/goals, you’ll be well on your way to reaching the big one. 3. CREATE A ROUTINE AND HAVE A PLAN Fail to plan and plan to fail! Having a game plan for the week ahead will help adhere to your goals, as there is less opportunity for impulsive behaviours. This may mean planning out your workouts for the week, meal prepping, and making a grocery list of healthy and balanced foods. In regards to exercise, scheduling in your workouts, and knowing what you're doing when and where, will take the stress off not knowing what to do and "winging" a sub-par workout. In turn, you will be more likely to follow through until your goal is reached. Building on these habits will make it easier to stay consistent with your goals. Stay organized! In addition, it is always a good idea to have a plan ready in case you fall into relapse. The biggest fallback for people creating healthy habits is that once you miss a workout, you eat dessert when you know you shouldn’t have, or if life just gets in the way… You say “oh well” and keep venturing down the wrong path rather than steering yourself back onto the right one. Having a plan in place in case this happens is crucial for helping with motivation post-relapse. 4. ENJOY WHAT YOU'RE DOING It is much easier to be consistent with exercise and nutrition when you enjoy what you're doing and eating. Exercise will be less of an obligation and you will be more excited to get moving. If you’re feeling stuck doing something you don't enjoy, try something new! Whether it be a new exercise class (HIIT, Spin, Yoga, Pilates etc.), getting outside, or joining a club/team. Bottom line is, you cannot be consistent if you dislike what you're doing. In regards to nutrition, implementing foods you don't enjoy will be doing yourself a disservice. Incorporating a variety of foods and flavours you love that also align with your goals is important in having a healthy attitude about food and staying consistent with your nutritional habits. 5. TRACK YOUR PROGRESS Seeing progress in yourself fuels motivation . There are several ways to track your progress: Monitor body measurements How your clothes fit Scale weight or body fat % Lifting heavier weight or doing more reps Check blood pressure Progress pictures How fast you catch your breath after you lose it Activities of daily living get easier to complete Energy levels improve Sleep gets better Tracking progress is essential to staying consistent. People get addicted to seeing results, which creates more and more motivation. When results aren’t achieved, it creates a sense of self-doubt, which reduces motivation because why would you continue if you aren’t getting any better? Even though you definitely should continue because exercise has so many benefits for you beyond the physical changes (bone, heart, emotional, cognitive health, etc.), it is still encouraging to see results and know you’re doing well. Need help with staying consistent? We have a team of friendly and well-educated personal trainers and health practitioners here at The Firm. Our mission is to educate and motivate you into living your healthiest and happiest life - even if it is just to get you started on your fitness journey. We are here to help you.

Dear valued members, The COVID-19 situation is continuing to develop in light of the Delta-variant. As such, the Government of Ontario has implemented COVID Vaccination Passports , which will affect the usage of facilities used for sports and fitness activities and personal training, including gyms. The Government of Ontario's website news release states that "Requiring proof of vaccination in these settings reduces risk and is an important step to encourage every last eligible Ontarian to get their shot, which is critical to protecting the province’s hospital capacity, while also supporting businesses with the tools they need to keep customers safe, stay open and minimize disruptions." We are striving to protect our members and our staff in these uncertain times, which means that starting on September 22nd, 2021, be prepared to show proof of full vaccination to be able to enter the gym. Starting at 12:01 am on the 22nd, those individuals who have not provided proof of vaccination will not be given access. Given the controversial nature of this mandate to some people, we want to remind everyone that this mandate is the same as the mask mandate - it was created by the government . Our staff, management included, can't and won't make exceptions to this policy, and we ask that members show the same patience, kindness, and respect that we have received thus far. In order to prevent a bottleneck on September 22, we will be allowing members to bring in their vaccination records during desk hours starting on Monday, September 13th. We will be requiring members to provide us with a photocopy or electronic copy of their vaccination receipts, which we will keep on file. When dropping the proof of full vaccination off at the front desk, we will also be taking your profile picture for our system. Non-Vaccinated Members If you are unable to show proof of full vaccination (2 doses + 14 days) by September 22, 2021, your fob will be rendered inactive. For those that have short-term memberships with an expiration date, your membership will expire. If required, we will give members a maximum of one-month extension on their expiration date if you need extra time to get fully vaccinated. For those that have a perpetual membership , you have the option to hold your membership at $5/month until you're able to provide full proof of vaccination. * Please email us if you require these accommodations with your request because these will not be done automatically. For members with a medical exemption to the vaccine mandate, we will require a copy of a written exemption letter from a Medical Doctor stating that you are exempt from receiving the COVID-19 Vaccine. We do not allow religious exemptions; letters from spiritual healers, chiropractors, nutritionists/dietitians; or self-claiming exemptions, etc. Reminders Let's keep the Aldershot community safe by following COVID-19 Protocols when not at home. Wear a mask when indoors in public Don't leave the house if you are experiencing COVID-19 symptoms Social distance when possible Sanitize your hands consistently, with soap and warm water Get vaccinated as soon as you can! When at The Fitness Firm... Keep your mask on at all times when on the main floor (yes, even when staff aren't here!) Maintain distance when possible Put all your equipment, weights, and plates back on the racks when you are finished with them Sanitize everything you touch after you use it Under no circumstances are you allowed to let individuals/friends into the facility who do not have a gym membership In the event of any falsified documents being discovered, the individual falsifying documents will be banned from The Fitness Firm until the COVID-19 pandemic is declared over (or longer). This is a criminal act under the Government of Canada's Criminal Code . Thank you Please note that these policies from the government are constantly evolving. This is all the information we have available currently, and these may change between now and the 22nd. Fitness is an essential component of peoples' lives, and it's moments like these where our purpose and values regarding the health of our members and staff matter a lot to our community and the individuals we serve. Thank you for your patience and respect for our decisions as we navigate this new government-required policy. Best, Fitness Firm Staff
