Trying to figure out if a food has gone bad? For food safety, simply looking at the food or doing a little “sniff test” isn’t a reliable or accurate way of determining food spoilage. But what if there was something on the food package itself that indicated whether a food has gone bad. Now there is!

A team of mechanical and chemical engineer researchers at McMaster University in Hamilton, Ontario have developed a thin, plastic transparent patch – about the size of two postage stamps – called the “Sentinel Wrap” to detect harmful bacteria and pathogens on food. The patch has tiny droplets of DNA molecules printed on one side that act as sensors to signal the presence of E. Coli, a type of types of bacterium that can cause food poisoning.

In Canada, about 4 million (1 in 8) Canadians are affected by a foodborne illness every year. Because it doesn’t affect the food at all, the Sentinel Wrap patch could be installed on the inside of a food package such as raw meat or raw poultry. If harmful bacteria are present on the food, the DNA molecules on the patch would light up under ultraviolet light. Shoppers could use a handheld device such as a smart phone, to scan the patch and immediately know whether there are any harmful bacteria present in the food.

The invention can still take two years before it comes to market. Until then, prevent food poisoning by following the four principles of food safety: clean, separate, cook and chill…and ditch the “sniff test”!

Broccoli Coffee – Do or Ditch?

latte 2

The other day, a colleague of mine asked on Twitter whether I was nay or yay for the latest trend – broccoli coffee!

In an effort to help Australians eat more fruit and veggies, researchers at the Commonwealth Scientific and Industrial Research Organization (CSIRO) created a broccoli powder made from both the florets and stems. Turns out that every two tablespoons of this powder contains about one serving of broccoli. While the broccoli powder could be used in smoothies, soups and baked goods, a café in Melbourne started adding it to coffee. The marketing pitch is that you’d get your first serving of veggies even before breakfast.

My take – I LOVE the idea of using all parts of the plant and reducing food waste, I’m not so sure coffee fans will perk up to the flavour (or smell?) of this new concoction. Personally, I like my coffee double-double (I only drink coffee about once a week) and I love my broccoli lightly steamed.

What do you think? Would you try broccoli coffee?

What’s the Latest Update on the Canada’s Food Guide?

canada's food guide better resolution

I was happy to attend the annual Dietitians of Canada conference in beautiful Vancouver last week and listened to a presentation by Ann Ellis – Manager of Dietary Guidance Manager at Health Canada – who shared the latest update on the revisions to Canada’s Food Guide.

Originally, the new Food Guide was supposed to be out by now, but Health Canada is waiting for additional data about Canadian’s eating habits, so the timelines have shifted.

Later this fall, Health Canada plans to launch a “Suite of Resources:

Canada’s Dietary Guidelines for Health Professionals and Policy Makers – A report providing Health Canada’s policy on healthy eating. This report will form the foundation for Canada’s Food Guide tools and resources.
Canada’s Food Guide Healthy Eating Principles – Communicating Canada’s Dietary Guidelines in plain language.
Canada’s Food Guide Graphic – Expressing the Healthy Eating Principles through visuals and words.
Canada’s Food Guide Interactive Tool – An interactive online tool providing custom information for different life stages, in different settings.
Canada’s Food Guide Web Resources – Mobile-responsive healthy eating information (factsheets, videos, recipes) to help Canadians apply Canada’s Dietary Guidelines.

In Spring 2019, Health Canada plans to release:
Canada’s Healthy Eating Pattern for Health Professionals and Policy Makers – A report providing guidance on amounts and types of foods as well as life stage guidance.
Enhancements to Canada’s Food Guide – Interactive Tool and Canada’s Food Guide – Web Resources – Enhancements and additional content to Canada’s web application on an ongoing basis.

Some other insights that I learned:
– Health Canada is hoping to get back to an overall pattern of eating and highlight nutrients of public health concern. The new Canada’s Food Guide will also have a heavy focus on food skills and determinants to health.
– There is no intent to advise consumers to avoid meat in the new Food Guide.
– The new Food Guide will focus more on the proportionality and frequency of meals, rather than numbers of servings to consume. In other word, information about number of servings may be more “behind the scenes” info for health professionals rather than front-facing info for consumers

8 Food & Nutrition Trends to Watch in 2018

Trends 2018

I’ve been keeping up with trends reports from around the world! Here’s what food and nutrition experts are predicting for 2018.

1. Fermented Foods. In a recent survey of 2,500 dietitians fermented foods are predicted to be one of the top trends for 2018. A source of the good, probiotic bacteria, fermented foods include yogurt, kimchi, sauerkraut, kefir, kombucha, miso and natto. (Today’s Dietitian)

2. New and Improved Canada’s Food Guide.
It’s been a decade since the last national food guide. With the much anticipated launch of the new Food Guide this year, we can expect to see messaging around not just what to eat, but also how to eat. (Dietitians Sue Mah & Lucia Weiler)

3. Hello Leftovers, Goodbye Food Waste. Canadians will continue to think about how their food choices can reduce food waste. Consumer strategies include a revival in the use of leftovers, right-size portioning and GIY (Grow It Yourself). (Loblaw Food Council)

4. Mindful Choices. Today’s consumers are thoughtful, mindful and conscious about making responsible food choices. They want to understand what is in their food and how it was produced in order to make informed decisions for their health, sustainability and ethical issues. (Innova Market Insights)

5. Rising Food Prices. The price of vegetables and the price of food purchased at restaurants will each rise 4-6% this year. Climate patterns are driving vegetable prices up. The average family of four in Canada will pay $348 more this year on food to a total of $11,948, and 59% of that budget will be spent on dining out. (Canada’s Food Price Report 2018)

6. Micro-markets for Food. As consumers are learning more about food, they are looking for more specialized, individualized choices that align with their personal values whether it be nutritional profile (fat, sugar, sodium, calories), location of production or antibiotic use. This is driving the development of micro-markets for specialized products. (Food Focus 2018)

7. Technofoodology. By the year 2020, there will be 24 billion internet-connected devices installed globally – that’s about 3 devices for every human on earth! This IoT (Internet of Things) revolution is changing the way we purchase, receive and interact with our food. There will be continued expansion of resources including Alexa, Google Home, “click and collect” online grocery shopping, as well as delivery of restaurant meals and meal kits. (Business Insider, Supermarket Guru)

8. Food Blockchain Revolution. Thanks to the Bitcoin, blockchain technology is taking off as a novel way for the agri-food business to record and disclose transactions in an open virtual space across the entire supply chain. From farmer to processor to packer to distributor to packaged goods maker to retailer to food service operator to exporter, blockchain technology brings a new level of transparency and information sharing. For example, in the event of a food safety recall, specific products can be traced easily and quickly. (Ketchum Food Forecast)

Choline – The Forgotten Nutrient

Egg cracked

There’s a growing buzz about choline and for good reason. Choline is essential for a healthy pregnancy and healthy brain development at all ages. And while choline was officially recognized as an essential nutrient in 1998, it’s only recently been added to the list of nutrients which can be voluntarily disclosed on Nutrition Facts Tables in both Canada and the USA.

Health Benefits of Choline
One of the main roles of choline is to produce a specific neurotransmitter called acetylcholine which plays a crucial role in sending messages from your brain to your muscles. During pregnancy, choline helps prevent the development of neural tube defects in the growing baby. Choline also helps to move fat out of your liver, which can prevent nonalcoholic fatty liver disease. According to the National Institutes of Health, there may be a link between choline and better cognitive function and memory as we age. Ongoing research is exploring the connection between choline and heart health too.

How Much Choline Do You Need
The amount of choline needed depends on your age. High intakes of choline from supplements can cause a fishy body odour, vomiting, excessive sweating and salivation, low blood pressure as well as potential heart and liver problems.

Food Sources of Choline

Our bodies produce small amounts of choline, but not enough to meet our daily needs. Liver, eggs (more specifically, egg yolks), meat and tofu are among the best food sources of choline.

Food and Nutrition Trends from FNCE 2017

Sue FNCE sign 1 CROP

We were thrilled to attend the centennial Food & Nutrition Conference & Expo (FNCE) – the world’s largest annual nutrition meeting hosted in Chicago by the Academy of Nutrition and Dietetics! With over 13,000 attendees, FNCE did not disappoint! The Expo trade show featured hundreds of food and nutrition products. Here are the ones that caught our eye!

PREBIOTICS and PROBIOTICS

Gut health is a growing trend! Prebiotics and probiotics work together to keep the gut healthy. Prebiotics are non-digestible carbohydrates that actually act as food for probiotics. Probiotics are healthy bacteria that live in our colon where they help to maintain a balance between the “good” and “bad” bacteria. From crackers to drinks to powders, these innovative products are designed to keep your gut healthy.

Health Canada Bans Main Source of Trans Fats in Foods

Trans-Fats

Trans fats. They’re the worse type of fat because they pose a double whammy to your heart health – not only do they increase the bad “LDL” (Low Density Lipoprotein” cholesterol, but they also decrease the good “HDL” (High Density Lipoprotein” cholesterol. Eating trans fats increases the risk of heart disease.

While some foods contain small amounts of naturally occurring trans fats, the real concern is with foods containing “artificial” or “industrially produced” trans fat. The main source of this type of trans fat is partially hydrogenated oils (PHOs) which are oils that have been created during a process called hydrogenation. This process changes the structure of liquid oils into a solid at room temperature. PHOs extend the shelf life of foods and are typically found in commercially baked goods (e.g. pastries, donuts, muffins), deep fried foods, French fries, hard margarine, lard, shortening, frosting, coffee whiteners, some crackers and microwave popcorn. When you see the words “partially hydrogenated oils” in the ingredients list, you know that the food contains trans fats.

While the food industry has been voluntarily removing trans fats from products over the years, many foods still contain trans fats. On September 15, 2017, Health Minister Ginette Petitpas Taylor announced a ban on PHOs from all foods sold in Canada, including foods prepared in restaurants, “Eliminating the main source of industrially produced trans fats from the food supply is a major accomplishment and a strong new measure that will help to protect the health of Canadians.”

The ban will come into effect on September 15, 2018.

Should You Be Worried About Lectins?

Beans_

I love eating different grains and beans. In fact, one of my favourite meals is lentils and rice. But there’s a growing buzz about lectins in these foods. Are lectins the new gluten? Here are 5 things you need to know.

1. Lectins are a family of proteins that bind to carbohydrates. Lectins are found in all foods, but are most concentrated in legumes and grains. Uncooked, raw legumes such as red and white kidney beans are one of the biggest sources of lectins. Lectins help protect plants from attacks by pests and insects.

2. Lectins aren’t easily digested, so they pass through the stomach and into the gut where they may “stick” to the gut wall. Eating high amounts of lectins may damage the lining of the gut, potentially causing digestive issues. For example, eating RAW or undercooked or improperly cooked kidney beans can lead to vomiting, diarrhea and abdominal pain.

3. Some people, such as those with Crohn’s disease or inflammatory bowel syndrome, may be more sensitive to lectins. If you have these conditions, speak to a Registered Dietitian to determine the amount of lectins that will minimize any symptoms or flare-ups.

4. Cooking eliminates almost all of the lectins in foods. Boiling legumes and grains in water for example is an easy way to get rid of lectins. Soaking beans, sprouting seeds and grains, and fermenting foods are other ways to lower the lectin content of foods. Canned beans have very low lectin levels due to the canning process.

5. Remember that many lectin-containing foods also provide important nutrients. Grains offer B vitamins, iron and fibre. Legumes offer protein, fibre, iron and zinc. So don’t worry about lectins. Instead, cook your grains and legumes, and enjoy!

What A Dietitian Eats

Sue Kelsey

As one of my monthly segments on CTV Your Morning, I thought it would be fun to do a little show and tell of my meals in a day. So here we go…this is what a dietitian eats!

Watch the interview here!

Breakfast – Veggie and cheese omelet

breakfast omelet

For breakfast, I try to make sure that I’m getting protein and veggies, so an omelet is perfect! Eggs are a great source of protein and the egg yolk is filled with nutrients such as lutein, omega-3 fat and choline. I add a slice of whole wheat toast for wholesome carbs and fibre. If I know my morning will be super busy, then I’ll make the omelet the night before and just heat it up in the morning for a quick breakfast.

Lunch – Lentil Shepherd’s Pie

lunch lentil shep pie

I love lentils! This is a fantastic vegetarian, plant-based lunch and a lighter version of your typical Shepherd’s Pie. Find the recipe here. Again, I’m looking for protein and veggies in my meal – lentils provide the protein and iron; carrots and stewed tomatoes count towards my veggies. The mashed potato topping is actually mixed with some cottage cheese to boost the calcium count. I pair this meal with some fresh fruit such as strawberries and kiwi – the vitamin C in the fruit improves the iron absorption from the lentils. My plan is to make this recipe on the weekend and re-heat it for a fast and nutrition packed lunch.

Afternoon Snack – Coffee, peanuts and fresh fruit

coffee snack

My mornings start at 6 am, so by mid afternoon, I’m feeling like I need an energy boost. A little bit of caffeine and some protein help me stay alert. Coffee is a treat for me – with double cream and double sugar! I aim to eat at least one green veggie and at least one orange veggie or fruit every day – I’m choosing a peach which is in season now. Peanuts are great for protein and they also contain magnesium which helps to fight stress.

Dinner – Baked salmon with quinoa arugula salad

Dinner salmon

I try to eat fish at least twice a week. Salmon is my go-to for heart healthy omega-3 fats, and it’s super easy to cook in the toaster oven. This is an Asian inspired recipe with a soy sauce and sesame oil marinade. I make a batch of quinoa ahead of time and use it in different ways throughout the week. Here, I’ve tossed some quinoa with arugula and added in some roasted beets and corn kernels. I set a goal to include at least 2 types of veggies at dinner time and make half my plate veggies.


Dessert – Fresh fruit salad with a small piece of dark chocolate

I usually have fresh fruit for dessert. Sometimes I’ll pair the fruit with a piece of dark chocolate. I love to bake, and never turn down a homemade cookie or slice of apple pie with ice cream!
