What are Canadian Children Eating?

CCHS found that the diets of Canadian children and youth are not as healthy as they could be. The Canadian Healthy Eating Index scores for the diets of Canadian children and youth show that younger children have higher average scores that decline with adolescence. About 25% of adolescents score less than 50. The low scores are due to an inadequate number of servings of fruits and vegetables, milk and alternatives, and grain

products. Saturated fat and sodium intake are higher than

desirable. 20% of children and 30% of adolescents consume kcalories in excess of their needs.

What are Canadian Children Eating?

CCHS indicates that 20% of children and 40% of adolescents consume food purchased at fast food outlets.

The Canadian Health Measures Surveys (CMHS) found that fitness levels have declined.

The proportion of obese or overweight children and youth has double since 1978.

Childhood obesity increases risk for chronic disease.


Diet-Related Disease Conditions in Children High-kcalorie, high-saturated fat diets

combined with low-activity lifestyles can lead to the following:

Obesity Type 2 diabetes Elevated serum cholesterol Heart disease Hypertension

Energy and Protein Needs for Children


Reading Labels of Foods for Young Children The labels of foods designed for young children must follow different

rules. Examples of changes made to labels for children under 2 years: under Nutrient Facts, fat must be listed as total fat the label must not have a nutrient claim about a food’s nutrient

content or health effects nutrient content claims are allowed for protein, sodium and sugar

content there may be claims that describe the percentage of vitamins or

minerals that apply to the Daily Values absence of percentage Daily Value for total fat, saturated fat,

cholesterol, total carbohydrate, fibre and sodium percentages of Daily Value for vitamins and minerals are shown


Typical Meal Patterns for Infants


Food Allergies and Food Intolerances Food allergies are more common in infants than in adults. Exposure to an allergen for the first time causes the immune

system to produce antibodies to that allergen. Allergy symptoms include sneezing, rash, eczema, hives,

cramps, aches, vomiting, asthma, diarrhea and many others. Allergy symptoms may be immediate or take up to 24 hours

to appear. Allergy symptoms may range from mild to life-threatening. Food intolerances do not cause antibody production. Food

intolerances create problems during digestion. Lactose intolerance, an inability to digest milk sugar, is an example of a food intolerance.


Food Allergies Labels must indicate whether the product

contains any of the top 8 food allergens: milk, eggs, fish, shellfish, peanuts, tree nuts, wheat and soy.

This is most often done by listing allergens at the end of the ingredient list after the word “Contains.”

Should their be a possibility of cross contamination, the label will contain a statement to warn consumers beginning with “may contain” or “not suitable for.”

Dietary Concerns for Teenagers

CCHS findings: Boys and girls aged 9 to 18 did not have adequate

intake of Vitamin A Girls 14 to 18 had low intake of B6, folate and B12 12% of adolescent girls were not meeting their iron

requirements 70% of girls aged 9 to 13 years and 30% of boys aged

14 to 18 years were not meeting their requirements for calcium

15% of girls aged 9 to 13 and 20% of girls aged 14 to 18 were not meeting their zinc requirements


Dietary Concerns for Teenagers (continued)

Teenagers’ inadequate vitamin A intake is due to their not meeting the recommended number of servings for fruits and vegetables.

Girls’ inadequate iron intake is due to their need for more iron. Girls tend to eat fewer iron-rich foods and consume fewer overall kcalories.

Teenagers’ inadequate calcium intake is due to their increased consumption of soft drinks.


Dietary Concerns for Teenagers (continued)


Dietary Concerns for Adolescents Adolescence is a time of independence and

changed behaviors. Dietary choices in adolescence can lead to nutrient deficiencies. Adolescents may be making decisions about:

Vegetarianism Eating for appearance and/or performance Smoking Alcohol use Oral contraceptive use Teenage pregnancy
