Food Diversity and Emerging Crops

Three insights into how diversity plays a role in food preference include parental influence on the foods their children eat, socioeconomic factors in food choices, and the idea that diversity and food preferences affect each other in a circular manner. Top emerging crops not native to Canada that are being grown in Ontario include spelt, Chinese vegetables, sweet potatoes, and hemp.


PARENTAL INFLUENCE
According to a 2017 study on how children develop a taste for more diverse foods indicates that parents significantly influence a child's willingness to try different foods according to "what is on the plate and the context in which it is offered."
Parents who don't try new foods will typically have children who won't try new foods. The converse is also true: "those who try new foods and have positive experiences are then more likely to try unfamiliar foods in the future."
Food preferences begin prenatally in that "preferences for salt and the refusal of bitter can be modified early through repeated exposure to flavors in amniotic fluid, mother’s milk, and solid foods during complementary feeding."
Mothers who consume a diverse diet may partially explain why "their breastfed children tend to be less picky and more willing to try new foods during childhood."
Moreover, infants that are only fed formula "do not benefit from the ever-changing flavor profile of breast milk," and because each brand of formula has a different flavor, formula-fed infants learn to prefer those flavors. As a result, they also tend to prefer foods containing those flavors.
Canadian pediatricians recommend that infants be offered a variety of flavorful food as soon as they are able to eat solids.

The study showed that early experiences with "nutritious foods and flavor variety" may increase the likelihood that they eat these foods in the future. Thus, the converse is true: if they do not have those early experiences due to unavailability of diverse foods, they may choose not to eat those foods in the future.

One of the strongest predictors of which foods children will eat is the types of foods they were exposed to as infants and toddlers.
After around age four, "reported dietary patterns/food habits remained quite stable, further highlighting the importance of getting children on the right track from the initial stages of learning to eat."
Moreover, the tendency to avoid certain foods can be reduced and "preferences can be increased by exposing infants and young children repeatedly" to diverse foods.
Due to the lack of diverse foods used in manufactured, processed products today, "the main educator of a child’s palate in today’s world may no longer be a parent but a series of multinational food companies."
Children tend to gravitate toward foods that are high in sugar and manufacturers responded to that by creating more foods that are high in sugar to meet those demands.

ECONOMICALLY DISADVANTAGED FAMILIES OFFER LESS FOOD VARIETY
A study out of the University of Queensland found that in an effort to waste less food, economically disadvantaged families give their children only what they like to eat, which means they are not "exposed to more diverse food from an early age, which results in poor food choices later in life."
Of the mothers surveyed in the study, 11% indicated they were "food insecure," meaning they had run out of money and food at least once in the past year. In these families, fruits were not common and the mothers were more likely to prepare separate meals for their picky eaters, which further reduced their exposure to diverse foods and flavors.
The scientists that conducted this research indicated this lack of diversity in foods at a young age was "likely to have a long-term effect on the child’s diet," meaning they would continue to choose foods that they grew up eating even when offered a variety of choices later on.
According to the Drivers of Food Choice in the Context of Food Systems Learning Lab, the variety of foods available is a driver of food choice.
Many poor neighborhoods lack access to full-service grocery stores, which further limits the options families can offer their children.
Moreover, it costs more to eat a diet that is rich in a variety of foods, as processed foods tend to be cheaper.
As one mother stated, "Value brands are the order of the day — not fast food... but things that cost little in energy usage, and can be cooked in an oven in 25 minutes. Stuff I know will be eaten. Risk-free food I know won’t end up in the bin. When I have just £2 in my pocket, it’s not the time to experiment and find out whether my 13-year-old would appreciate a quinoa-and-aubergine bake."
She further stated that she cannot afford to take risks with food because she would not be able to buy an alternative if her child does not eat what she prepares.

FOOD PREFERENCES ARE DRIVING FOOD DIVERSITY
According to Sustainable Food Trust, on a global basis, there has been a "shift away from multiple traditional diets towards a single modern one."
As a result, agricultural supply has shifted toward producing the "same sweet-salty flavors and the same core ingredients of processed grains, sugar, refined oils and meat."
Sustainable Food Trust states that "Food diversity has to happen at the level of individual food choice" because it is human nature to "eat what we like, and we like what we know."
One of the reasons why people's food choices are so narrow is because "we have a food system that sells us an illusion of choice rather than a real diversity of ingredients."
There are about 7,000 edible crops in the world, but 95% of what is currently eaten comes from just 30.
Approximately half of the average person's calories come from just six ingredients, which are "animal foods, wheat, rice, sugar, corn and soybeans."
Access to food is not enough if a person does not want to eat it, so efforts need to be taken to give people the opportunity to learn to like new foods by giving them access to them.

CONCLUSION
As David Mela, author of "Food choice and intake: the human factor", "If it is not available, it will not be eaten. If it is available, it is likely to be eaten. If there is no alternative, it will be eaten."
There is clearly a link between food diversity and food preferences, as children who are exposed to a variety of foods when younger will grow up eating a variety of foods.
In poorer areas where food waste is a concern, families tend to serve the same foods repeatedly because they know their kids will eat them. This reduces exposure to new foods and can impact future food preferences.
Children who are exposed to a limited variety of foods tend to grow up preferring mostly what they ate when they were young.
There also appears to be a "self-reinforcing cycle" concerning food preferences and food diversity in that people's food preferences drive supply, which then results in the production of more foods that people prefer, thereby narrowing overall food diversity.

EMERGING CROPS IN ONTARIO, CANADA
Approximately 400 acres of crops in Ontario, Canada are growing specialty foods like "grapes, quinoa, edamame, tiger nut and hops."
Hop crops have seen a re-emergence in Ontario partially due to "the explosive growth of the craft beer industry."
OMAFRA new crop development specialist Evan Elford stated that the province is finding the development of production guidelines for these specialty crops challenging because they pose unique problems that are new to the region.
For example, over 2 million acres of soybeans are grown every year in Ontario and because edamame are fresh market soybeans farmers expect the soybean crop protections would cover edamame. However, this is not the case because edamame is a fresh market crop and requires a different process.
In 2011, University of Guelph researcher Glen Filson stated that some world crops like okra and amaranth could possibly be grown in Ontario and may represent a $60 million per month market in the Toronto area alone.
As of 2017, one-fifth of Ontario's farmers had tried growing a new crop since Filson made his statement.
Reasons for trying new crops included filling a niche market, changing markets, emerging opportunities, crop rotation, environmental benefits, and reduced risk due to diversification.
Buckwheat, hemp, quinoa, and hazelnuts are among the most popular emerging crops in Ontario.
Other very niche crops that farmers in Ontario are experimenting with include "bok choy, eggplant, hard cider apples, hops, malting barley, faba beans, Jerusalem artichokes and pap paw."
Crops that are being grown for rotation, sustainability, and energy purposes include "Austrian winter peas, switchgrass, flax, millet, oats, miscanthus, mustard, spelt and peas."
Still other crops are being grown in Ontario for their health benefits. These include "garlic, goji berries, haskap berries, kale, purple potatoes and persimmon."
In 2016, the largest emerging crop by acreage is spelt, with 7,365 acres. This is followed by Chinese vegetables, with 1,953 acres and sweet potato, with 1,755 acres.
Some emerging crops in other parts of Canada that have yet to be grown in Ontario include fenugreek and camelina.
However, in 2016, researchers in Ontario began conducting plot trials in Ridgetown, Simcoe and Winchester to see how camelina performs and "how it might best fit into a typical Ontario cash crop rotation."
Gooseberries and kiwi are extremely new, with just eight and 12 acres respectively in 2016.
A main driver of new crops is a University of Guelph study that showed there are 800,000 Canadians of South Asian descent who are living in Toronto and spending $33 million per month on vegetables like okra, Chinese long eggplant, and Indian round eggplant, most of which was imported.
The province decided to research whether these vegetables could be grown domestically to replace at least a portion of the imports.
In 2015, six commercial growers and a number of smaller farms in Ontario planted 80 acres of Asian eggplants and okra.
This resulted in a 2% reduction in imported eggplants over the 2014 amount of 24 million kilograms.
Asian eggplants can yield between $5,000 to $9,700 per acre in profits, which makes it an attractive crop for small operations.
"Research trials and commercial operations" in Ontario and other provinces are growing okra, which has proven to be a lucrative crop if growing conditions are right. For instance, a farmer in Manitoba sold five acres of okra for $36,000 in 2015.
Ontario's Ministry of Agriculture Food & Rural Affairs has a section of its website devoted to specialty crops where farmers can get information on how to grow them in Ontario.
