What’s in your grocery cart?

Locally produced – food is... Fresher made with fewer chemicals grown by smaller (private) farms.

Imported: Brought in from a outside source.

100 Mile Diet

Eating foods produced from within 100 miles of where you live. Difficult for us in NL?

Exported Items from NL

Locally produced foods: Roadside/local markets local bakeries Foods connected withMade Right Here” program

NL Exports

Some exported foods are: Fish products Berries Purity Factory goods Savory Yogurt Bottled water

Journal #4- Ch. 23 p. 476

What foods are produced in Canada? Make a list of the provinces and territories and note the foods for which each is known.

Staple Foods

Staple food: Is regularly eaten in a community

Food from which people obtain most of their calorie requirements.

Staple Foods in Canada

Include meat, dairy, potatoes, eggs and grain.

Canada has no single main staple - a variety of foods serve as a basis

Due to different regions and groups (ex. Alberta vs. NL).

Food Industries

Food industries include, but are not limited to: Grain & Oil Seeds Industry Dairy Industry Poultry & Egg Production Beef Industry Horticulture (fruits/vegs/seeds) Fish Harvesting

Food Industries

Convenience foods: More people working = less time spent in the kitchen preparing meals.

Demand has increased for quality convenience foods.

Convenience Foods

Convenience foods include: Pre-washed and cut vegetables Ready made salads & dressings

Shredded cheese Frozen foods Meal replacements

Convenience Foods

What health effects are associated with the use of highly processed foods?

Processed foods have been compromised by the addition of Hormones Additives Preservatives unnatural genetic material chemical or heat treatments that alter or destroy the natural healthy nutrients

Processed Foods continued...Most processed foods contain high levels of sugar, high fructose corn syrup or white flour.

Aka Refined carbohydrates - have a great effect on your blood sugar and insulin.

Processed Foods continued...Processed food is NOT real food.They are the products of chemical and mechanical manipulation

many contain residues of pesticides, genetically altered ingredients and synthetic chemicals.

Processed Foods continued...

The human body needs fresh whole foods that are rich in nutrients to maintain natural health and energy.

This is evident if we view populations around the world who don't eat processed, refined or chemically altered foods.

These people eat traditional diets of clean, whole, vital foods, and they are healthy, strong, and free of the diseases while plague industrialized countries (heart disease, cancer, diabetes and stroke).

Article: “There’s more to Organic farming than being pesticide free”.

Journal #6 - Organic Farming #1: List the practices used in

both organic and traditional farming.

#2: List the practices for organic farming only.

#3: List the practices for non-organic farming only.

#4: Why choose organic foods? #5: What is the number of farms

producing organic foods?

Food Trends Items consumers buy based on how

well they are marketed by advertising companies.

Companies track the spending habits of customers – then they cater to the population needs (ex. Increase in gluten-free products).

Food Trends

Current Trends in Canada: 88% stated that when making food choices, nutrition is of some importance.

34% consumed less fat 26% ate more vegetables 14% reduced sugar intake.https://www.youtube.com/watch?v=LzZGZydOG7U – 2015 food trends

Canadian Trends continued…Findings show that health and nutrition are important to Canadians.

This trend drives the introduction of new food products.

Common Food Trends

Aquaculture versus traditional fishing

Traditional family versus agribusiness

Use of additives in food processingPesticide use vs organic growing

Common Food Trends

Meat and egg replacements sports bars and meal replacements convenience foods additives, fortified and enriched foods Fat free products, low carbohydrate vegetarianism

Food Trends

Who/What drives food trends?

The consumer? The industry? Or Media?

ALL THREE play an important role in the food industry.

Food Trends

Is there a shift in the amount of certain foods that Canadians consume?

Through research, there has been new products on the market and old food ingredients have been given a new twist by helping consumers to recognize their potential health benefit.

Examples?

Biotechnology

Is the manipulation of living organisms to produce new goods (i.e., pesticide-resistant corn)

https://www.youtube.com/watch?v=jAP6ZtfP9ZQ – What are genetically modified foods? (7 mins)

Novel Food

a substance, including a microorganism, that does not have a history of safe use as a food

a food that has been changed by a process that has not been previously used on that food (preserved, manufactured)

Novel food continued

A food that is derived from a plant, animal or microorganism that has been genetically modified such that The organism no longer shows characteristics or falls within the anticipated range for that organism

Genetically Modified

Genetically modify means to change the heritable traits of a plant, animal or microorganism by means of intentional manipulation.

Goals of Biotechnology

To increase the quantity and quality of food.

To enhance nutritional value.

To prevent disease.

Biotechnology & Developing Countries

It is hoped that Biotechnology can be used by developing countries to have more control of their food supplies (independence).

Seeds are being developed that can grow and thrive in poor conditions, and be resistant to disease and pests.

Question p. 668

Answer the following questions listed in your text:#1, 2, 4, 5, and 7

Safety & Biotechnology

Biotechnology is regulated through Health Canada and the Canadian Food Inspection Agency.

All products must undergo a safety assessment.

Safety Assessment

The following factors must be considered: How the food crop was developed.

the changes made in DNA. What the new food is made of, compared to the non-modified food.

Safety Assessment

What’s the nutritional value of the new food vs. non-modified

Are there new toxins? Will it cause allergic reactions?

Labeling of Genetically Engineered Foods in Canada

The guidelines for Canada: Require mandatory labeling if there is a health or safety concern.

Labeling needs to be understood, is true, and not misleading.

Food-Packaging Technology

All packaging is designed to keep food safe from damage and contamination.

Technologies allow for less preservatives or chemicals to be added to food, but has increased the waste.

Developments in Food PackagingResealable plastic bagsGable tops with spouts on milk and juice cartons.

upright flexible packages used to hold beverages.

Condiment bottles that pour from the bottom

Class Brainstorm

Given the use of convenience foods and its packaging, what management strategies could the family employ to minimize environmental damage?
