Study Notes

KINE 1020 - Introduction to Nutrition

Course offered October 23, 2024, by Dr. A. Josse
Focus on serving sizes and ingredient lists, including changes to food labeling in Canada
Updated serving sizes reflect typical Canadian portion sizes
New food labeling to make similar foods easier to compare
New labeling is more realistic reflecting typical one-sitting consumption amounts
Ingredient lists previously misleading, now grouped together for a clearer understanding of sugar content

Serving Sizes

Original methods of measuring food servings difficult to compare similar products.
New Canadian labeling is consistent with serving sizes in one sitting.
Updated Canadian food labeling makes comparing similar foods easier.

Ingredient Lists

Previous labeling was sometimes misleading, causing consumers to misunderstand the amount of sugar present in products.
Similar products are now grouped together in ingredient lists to provide a more accurate understanding of sugar content.
New labeling groups sugars according to type and quantity
Includes sugars like white sugar, beet sugar, raw/brown sugar, agave syrup, honey, maple syrup, barley malt, molasses, fructose, glucose and any glucose-fructose combinations

Nutrient Content Claims

Calorie-free: Less than 5 kcal per serving
Low in Calories: At least 25% less energy than original product
Light: At least 25% less energy than original product
Fat Free: Less than 0.5g of fat per serving
No fat: Less than 0.5g of fat per serving
Zero fat: Less than 0.5 g of fat per serving
Low in Fat: 3g or less of fat per serving and 30% or less of the energy from fat in pre-packaged meals
Reduced in Fat: At least 25% less fat than original product
Lower Fat: Less than 0.5g of fat per 100g; contains no added fat
100% Fat Free: Less than 0.5g of fat per 100g; contains no added fat

Healthy Eating Strategy - Canada

Nutrition Facts Panel improvements
Canada's Food Guide recommendations
Restrictions on marketing to children
Front-of-pack (FOP) labeling

Genetically Modified Foods

Foods have been genetically modified for many years
Pros: Increased crop yields, resistance to bacteria, meeting global food challenges, reduced use of pesticides, and better shelf life.
Cons: Unknown long-term health effects on humans, gene deletion/insertion, and unknown effects on the food.

Common GM Foods

The presentation provides a list of common genetically modified foods, including soy, corn, canola oil, alfalfa, cotton, papaya, zucchini/squash, sugar beets, milk (in some countries not others), and meat (if meat feed is modified).

Natural Health Products

Regulations on natural health products came into effect in 2004
Complementary or alternative medicines, supplements
Defined ingredients (amino acids, vitamins, minerals, herbs, etc.)
Include traditional medicines (Chinese/East Indian), homeopathic medicines, probiotics, certain toothpastes, antiperspirants, shampoos, facial products, and mouthwashes
Must be safe for use as OTC products, no doctor's prescription needed

Natural Health Products (Continued)

Safety assessments of NHPs are performed
Safety and quality of NHPs are assessed and authorized for sale in Canada
NHPs may be linked with health claims associated with ingredients
Issues related to safety based on the assessment of side effects

EGCG Warning

Article from 2019 about a study warning about EGCG, a component of green tea.
Side effects can lead to liver and kidney damage, specifically when concentrated levels of EGCG are consumed (above 800mg of green tea extract daily)
Caution needed for use of supplements

Sport Ergogenic Aids

Several "beneficial" ergogenic aids that improve athletic performance, which include:
Sodium bicarbonate,
Beta-alanine, Caffeine, Creatine, BCAAs, protein supplementation, sports drinks/gels, bars, beetroot juice (nitrate), and antioxidants

IOC Consensus Statement

Dietary supplements may have benefits for elite athletes.
IOC recommends a risk-benefit assessment for supplement use
IOC states that dietary supplements and the high-performance athlete are discussed in recommendations

Contamination of Nutritional Supplements

In 2004, Geyer et al's study, supported by the IOC, found concerning amounts of undeclared hormones and steroids in supplements.
The study indicated a significant portion of tested supplements contained substances not listed on the label, including hormones

Risks of Sport Supplement Use

Athletes should proceed with caution when using sport supplements.
Risks associated include potential negative effects, waste of time, money, and energy, as well as potential contamination from undeclared ingredients
Important to carefully consider cost-benefit before using supplements.
