Is it #NutritionMonth2019 or #DairyFarmersofCanadaMonth and #AvocadosofMexicoMonth?

We need to talk about Nutrition Month. More specifically, we need to talk about Dietitians of Canada’s Nutrition Month recipes. It’s been a long time (back in 2012 to be specific) since I wrote about the issue of sponsorship in regard to DC’s Nutrition Month materials. To be honest, I feel like a bit of a traitor doing it (DC does many great things to advocate for dietitians), but I think that it’s a real issue. Accepting sponsorship for Nutrition Month is undermining DC’s (and by association all Canadian dietitian’s) credibility.

When DC first released their Nutrition Month recipes I was disappointed, but not surprised, to see that they were sponsored by Dairy Farmers of Canada and Avocados from Mexico. Don’t get me wrong, I consume both dairy and avocados. This is not to cast aspersions on either of those foods. However, I think that a dietetic organization accepting sponsorship from the food industry (no matter what the foods are) creates a conflict of interest. I also think that there are additional reasons why featuring these particular foods in DC resources is problematic. I’ll get into that a little later. So, as I said, I wasn’t surprised. This is nothing new for DC. I had a little rant with my RD colleagues (one of whom also happened to point out that the content of the handouts, aside from the recipes was simply duplicated from last year, sigh) and then let it go.

My frustration was reignited last week when fellow RD, Pamela Fergusson voiced her concern about the industry sponsorship of Nutrition Month on Instagram last week. She’s also written an excellent blog post about this issue that you should read.

That got me curious so I went on the Nutrition Month website and counted how many times dairy and avocados appear in their featured recipes. Out of ten recipes, eight include dairy and four include avocados. There are 12 additional recipes on their handouts, eleven of these include dairy and six include avocados. That’s a lot of dairy and avocados!

While I love avocados, they are freaking expensive. They’re usually about $2 a piece at the grocery store here. Given that food insecurity is an issue across Canada, DC even has position papers on both individual and household and community food insecurity, it struck me as a little inappropriate for them to so prominently feature a food that’s not within the budget for many Canadians. Even for those who don’t struggle with food insecurity, avocados are often more of a luxury item than a staple food. The same goes for many dairy products, particularly cheese, which is featured in many of the DC Nutrition Month recipes. Realistically, who’s making a “crab and remoulade sandwich” for lunch??

In addition to the issue of cost, there’s the lack of alignment with the new Food Guide. Despite what many people would have you believe, milk (and dairy products) have not been removed from the new Food Guide. They’ve simply been incorporated into the new “protein foods” grouping. However, there is a strong emphasis on choosing plant-based sources of protein more often. I realize that DC would have already developed their resources before the new Food Guide came out. Even so, the old Food Guide only recommended two servings of milk (and alternatives) daily for adults. No matter which Food Guide you look at, it doesn’t make sense that DC would feature dairy in the majority of their Nutrition Month recipes.

This takes me to one last issue that I stumbled upon while tallying up the recipes featuring dairy and/or avocados. That issue is the nutrition information for the Turmeric Basil Roasted Turkey Burger. This burger contains 936 calories, 48 grams of fat (9.1 g of which are saturated), and 773 mg of sodium. To put that in perspective, that’s 416 more calories and 20 grams more fat than are in a big mac (177 mg less sodium though). It’s about 3/4 of a day’s recommended maximum intake of fat and over 1/3 of the maximum recommended intake for sodium. That’s just in one burger! I thought for sure this had to be a mistake so I tweeted at DC to ask them about it. This is the reply I received:

6C9833A8-57D1-4F39-BA2C-D8B025E2D23E

A “hearty” burger indeed! As much as I believe that all foods fit and that having treats is part of a healthy diet, I really don’t think that a recipe like this is appropriate for a dietetic organization to be promoting. When people are looking for recipes from Dietitians of Canada they’re looking for recipes that meet certain nutrition criteria. They’re looking for recipes that are going to provide them with a reasonable number of calories, not too much fat or salt or sugar and plenty of vitamins and minerals. I think it undermines their credibility as an organization when they allow sponsors (such as Avocados of Mexico who developed this recipe) to be put ahead of the public who rely on dietitians for unbiased nutrition information.

Is milk out?

I’ve been hearing a number of complaints and concerns about the new Food Guide. The one I’ve been hearing the most is that “dairy is out”. I’d like to dispel that. No, dairy is not “out”. Yes, the “milk and alternatives” food group is gone; as is “meat and alternatives” but milk and dairy products still fit within the protein group in the new guide.

The Food Guide now recommends a proportion-based approach to eating, rather than a more prescriptive portion-based approach. Rather than telling you how many servings of each food group to have every day, and how big a serving is, the new guide simply advises you make half your plate vegetables (and fruit), one quarter protein foods, and the other quarter whole grains. It promotes consuming plant-based protein foods “more often”. This is pretty subjective and should – in theory – make it a lot easier for people to adopt. For some people this may mean consuming plant-based protein foods in larger amounts than animal-based proteins. For others, this may mean consuming plant-based sources of protein more often than they usually do. In a country that’s extremely meat-centric this could mean something as simple as adding more beans to a chili and cutting back on the meat slightly.

I’d also like to point out that given that a quarter of your plate should be devoted to protein foods you can easily mix and match to your heart’s content. This might mean that you have lentils and salmon (like I did last night), cheese and bean casserole, tofu and chicken, etc. It might mean that at one meal your protein comes from milk or meat but that at another it comes from legumes or nuts. Snacks can (and generally should) also include a source of protein. If you eat three meals and two snacks a day this means that there are ample opportunities for you to consume protein from a variety of foods, including milk products if you desire.

Personally, I think that having a food group specifically for milk (and alternatives) was unwarranted and I’m glad to see it go. There are many people who can’t consume milk products (due to lactose intolerance or an allergy) as well as those who choose not to and it is entirely possible to consume a nutritious diet without the inclusion of milk. For those who are concerned about where people will get their vitamin D and calcium from without milk products there are other food sources of these nutrients.

Vitamin D is pretty near impossible to consume enough of through food sources alone anyway, at least during the winter months in Canada and Health Canada recommends all adults over the age of 50 take a supplement of 400 IU/d. I’d also like to point out that milk is fortified with vitamin D as are most plant-based milk alternatives (always check the label to be sure). Other food sources of vitamin D include: egg yolks, salmon and other fatty fish, some meats, and other fortified foods which may include things such as orange juice and cereal.

Non-dairy food sources of calcium include: dark leafy greens (like spinach, collards, and kale), soy beverage, canned fish (eat those bones!), tofu (if prepared with calcium), beans, nuts, seeds, and even blackstrap molasses.

If you are concerned that you may not be meeting your nutrient needs through your diet I recommend keeping a food journal and making an appointment with a registered dietitian.

Should the government allow industry to market to kids in schools?

 

30947956812_761a3c6cc9_b

Last week I found out about a new food literacy initiative. According to the introduction to their online survey (which unfortunately only wants input from teachers, principals, and board of education consultants) this initiative will involve visits to schools to provide hands-on healthy eating education opportunities. This initiative is an undertaking of the Dairy Farmers of Canada.

I am all for getting food literacy education back into schools. I think that by educating children from a young age about growing, harvesting, preparing, and enjoying food we could prevent a lot of the unhealthy eating habits and chronic diseases that are so prevalent in our society. However, I don’t think that this should be done by any means necessary, and I see the provision of food literacy education by industry as highly problematic.

This is nothing against milk, or the Dairy Farmers of Canada. Milk is a nutritious food and can (although it doesn’t have to) be part of a healthy diet. I love lots of dairy products. I still don’t think that it’s appropriate for Dairy Farmers of Canada to be providing nutrition education in public schools.

From the Dairy Farmers of Canada website:

Run for farmers by farmers, Dairy Farmers of Canada is the voice of Canadian dairy farmers.

Dairy Farmers of Canada (DFC) is the national policy, lobbying and promotional organization representing Canada’s farmers living on approximately 12,000 dairy farms. DFC strives to create stable conditions for the Canadian dairy industry, today and in the future. It works to maintain policies that foster the viability of Canadian dairy farmers and promote dairy products and their health benefits.

Dairy farmers fund its operations, including promotional activities.

I think that makes it pretty clear what their mandate is. It’s not to provide unbiased nutrition education to children. It’s to promote their products to consumers. Make no mistake about it, that’s what they would be doing by providing food literacy education to children in schools. They would be marketing to the next generation of consumers.

Would it be appropriate for Coca Cola, McDonald’s, or Frito-Lay to provide food literacy education to a captive group of school children? Just imagine if KFC announced that it would be providing food literacy education to children in schools. Parents and the public would be freaking out. It’s no more acceptable for the dairy industry to be given access to children in schools just because some dairy products are nutritious. It’s highly inappropriate, not to mention ironic, for any food industry lobby group to be marketing to children in schools whether it be under the guise of food literacy education or not.

Local Food Week: a dairy farmer

Today’s guest post comes from Jen Christie, a dairy farmer in Ontario. We connected on twitter a little while ago. She’s been a great supporter of my blog so I was happy to hear that she was interested in writing a guest post for Local Food Week when I put out the call a few weeks ago. She also sent me a bunch of amazing photos (with captions!) to choose from to include with her post. I couldn’t choose just one so my apologies for the inundation of images today. Hey, it’s Friday :) For more from Jen, you can find her blogging at Savvy Farmgirl or follow her on Twitter @SavvyFarmgirl.

My nieces helping feed hay in the new dairy barn.

Note: Even with all my travel, work and volunteering, my favourite place to be is still the farm. 

This post is a tribute to my family who works day-in, day-out and encourages me share their story through social media even though I’m not there alongside them everyday. It’s because of them I’m so passionate about agriculture.

Why do we farm? It’s a question my family has talked about a lot lately as consumers, environmental groups and government put increasing pressure on how we farm. For us, the answer is simple, although the work itself is typically not so much.

IMG_6186.jpeg

My brother getting ready to combine corn in the fall. If it snows early, sometimes we have to combine in the snow to get the crop off.

We love growing crops and producing milk for Canadians to enjoy. It’s in our blood. Our farm has been in my family since my dad’s ancestors emigrated from Ireland in the 1800’s. My mom grew up on a farm, which my Opa purchased after leaving his farm in Holland after the war. It’s been said that farmers grow roots in their land, and for my family, I believe this is true.

We are passionate about farming, and it’s nearly impossible to say what we we love most. When we talk about why we farm, my mom and dad and brothers will all name different reasons, then all agree with each other. Watching seeds sprout from the ground and then each day growing taller. Helping a new calf into the world. Listening to cows happily “munch” on hay at dusk. The satisfaction at the end of a hard day, feeling you did something.

IMG_1310

My brother helps his 5-year-old daughter wash her calf so she can take it to the local fair. Growing up, we all participated in local fairs, showing a different calf each year in 4-H.

The list is endless and among these reasons, there are also differences between my parents and brothers.

My dad loves the challenge of trying to breed the “perfect cow”. He started with a few dairy and beef cows from his parents and over the past forty years he grew our herd to 150 cows, with each generation getting better and better.

IMG_0107

My parents work together to roll out a bale of hay for the heifers. The hay is grown on our farm and baled into round bales or large, rectangular-shaped bales. 

By contrast, my youngest brother loves using data to make better decisions about cow care. We built a new barn two years ago and our cows are milked with a robot. The 60 cows we milk visit the robot whenever they wish, and the robot collects information he then uses to care for each one individually. Cow “Fit Bits” even tell him when a cow may be sick by monitoring her eating and walking habits!

IMG_1834

My brother sorts milk samples the robot has taken to test each cow’s milk quality.

My other brother loves being in the field. He loves big tractors and equipment and yes, probably some days, it seems he’s just a big kid playing with his toys. Behind the scenes though, he is always planning and trying to find ways to be more sustainable. He experiments with cover crops and is constantly striving to improve soil health, while also maintaining the amount of soybeans or wheat he produces.

IMG_6028

My nephew watches as we unload soybeans from the combine into the wagon. From there they are either stored for feed on our farm or trucked to a company who will export them.

Finally, my mom is fiercely proud of the calves she raises. She ensures they get a good start, paying close attention to each one of them as they grow up. She considers it our duty to produce a quality product which will make great butter, ice cream and cheese. She has done so, alongside my dad everyday for over thirty-five years, with rarely a holiday or a break. (I can count on one hand how many vacations we took as kids.)

Common for everyone is the opportunity to raise their family on the farm. Growing up on the farm served me well, teaching me the value of hard work, respect and compassion among other things. My brothers’ kids are following in our footsteps. At only 2, my youngest niece asks to go to the barn every night and her older brother knows the name of every piece of equipment. My oldest niece can explain to any visitor how the robot works and what we feed our calves and she is only 6!

It’s not all rosy though. Weather is always the biggest variable and of course, we have no control over it. Luckily, in Ontario we get pretty consistent heat and rain and we don’t experience the extreme droughts or hail Western Canadian farmers get. Equipment breaks and everything goes on hold to fix it. Cows get sick and sometimes even the vet can’t figure out why. It’s heartbreaking to lose an animal and it will often weigh on our minds when we do.

Then, there is the cost of operation. For us, land and quota are our biggest expenses. To continue supporting 3 families, we need to be able to grow. To make the cost more manageable, we try to add a little more land or a few more cows each year.

Despite the long days and heartbreak that comes with farming, my family wouldn’t do anything else. We love what we do and we love being part of a small community where everyone knows each other and pitches in to help.

For us, every week is “local food week” because the strength of our small town depends on its citizens buying from local businesses and participating in local events. We are grateful that Canadians buy our dairy products everyday and the least we can do is pay this forward by buying local and buying Canadian.

The milk truck comes every other day to pick up our milk for processing into butter, cheese, ice cream, and pasteurized milk.

A closer look at the full-fat dairy prevents T2 diabetes study

6057862984_a67f303a9f_z.jpg

Findings of a study suggesting that full-fat dairy products might be protective against the development of T2 diabetes hit the news recently. Of course, you know me, I was curious if the research was sound.

One of the primary authors holds a patent for the use of trans-palmitoleic acid (one of the common fatty acids in dairy products) for the prevention and treatment of insulin resistance, type 2 diabetes, and related conditions. Right off the bat, there’s a red flag as it stands to benefit the author if he can support the assertion that high-fat dairy (or at least one fatty acid in dairy) can treat T2 diabetes.

I thought that it was interesting that they chose to use circulating fatty acid biomarkers as determination for consumption of full fat dairy products. This sounds like a better idea than the typical self-reported food frequency questionnaire. However, I wondered how accurate such a measure is. It seems that I wasn’t the only one with such a concern. When I searched to find out the accuracy of the use of such biomarkers I came across a letter to the editor expressing concern that some of the FA biomarkers used could also be attributed to fish consumption. Some of the FAs used in this study can also come from other meats, so may not all be attributable to dairy consumption. It seems that there are some additional limitations to use of biomarkers in research as lifestyle and disease state factors may affect metabolism and the resulting presence (or absence) of such biomarkers. Essentially, while the use of biomarkers may seem objective, they may not tell the full story. I also question how long biomarkers such of these remain present in the blood following consumption of dairy foods. Would they be indicative of long-term diet patterns or simply of having recently consumed high-fat dairy? Not being knowledgable in the area of biomarker research I can’t answer this question so it may or may not be worth raising.

Importantly, to account for potential confounding variables, the researchers used self-reported physical activity and food frequency questionnaires. Thus, there is always the potential that there might be another cause for the development (or prevention) of T2 diabetes in study participants.

There are also concerns regarding the actual study participants. The researchers used participants in the Nurses Health Study and the Health Professionals Follow-Up Study. These participants, health professionals, may not be reflective of the general population so generalization of the results to all Americans, or those in other countries is not necessarily possible.

I’m also not convinced that, while statistically significant (where is my personal statistician?*), the results hold any real-life meaning. The number of cases of T2 diabetes diagnosed in all study participants wasn’t huge so a 36-44% risk in reduction, while sounding massive, might not translate to a huge decrease in risk in actuality.

*After writing this, I had a friend with an advanced math degree offer to take a look at the original research for me (thanks Scott!). Here’s what he had to say:

My only concern with the data is the sample size of 3,333 which is not that large considering the amount of variables that they are accounting for. More variables the more likelihood of outliers that may not be actual outliers, but the sample size is so small it appears that way. However, they seemed to have introduced enough controls in their testing to reduce the risk.

What does all this mean? Basically, don’t go crazy on high-fat dairy products just yet. However, as you should only be eating a couple of servings of dairy a day anyway, you should go with foods that you enjoy. Why not have a variety of foods; maybe low-fat milk on your cereal, but full-fat yoghurt for a snack? Variety is the spice of life.
