Presentation OutlineFour scenarios of low-income households to

illustrate the difficulties to eat nutritious foods1;Impact of poverty on health;Effects malnutrition throughout the life cycle;Nutritional status of the elderly and associated health

risks;Conclusion.1 These scenarios are based on calculations from Statistics

Canada and the Common Front for Social Justice’s data.

Overall, many low-income people are worried about their food intake

These four scenarios show that certain groups do not have enough money to buy nutritious food;

These calculations are conservative because there is nothing included for health care, leisure, newspapers and books, educational activities and insurance payments.

Impact of poverty on health1

Health status is worse for those with lower incomes and this was demonstrated in 16 studies conducted in four different countries;

A national survey indicates that 73 % of Canadians in the highest income group rated their health as excellent while only 47% of Canadians in the lowest income group reported excellent health.

Disease frequency (Source: Phipps, 2003)

Chronic diseases are much more common in the poorest regions of Canada:–10.1% of adults between 15 and 64 years

old living in the Maritimes reported high blood pressure versus a national average of 6.8%;–17.0% of children from the Maritimes

suffered from asthma, compared to 12.7% for children’s national average.

Three major effects of malnutrition1. Difficiencies in protein, vitamins and minerals

(iron, zinc, vitamins A, B6, B12, C and folates) lower the level of antibodies, making people more prone to various infections, the flu, etc.

2. An iron defficiency reduces the size and color of red blood cells, thus lowering oxygen transport to tissues (this leads to fatigue, muscle weakness, drop in productivity, etc.);

3. A lack of calcium is associated with calcium withdrawal from bones (fragile, and less dense)

• In the U.K., a 10-year difference in life expectancy was observed between rich and poor neighbourhood;

• Income increase is associated with improved health status, especially among the poorest;

• Countries with the narrowest income gap are those where the population is in better health

• Our elected politicians would improve the health of our population if they increased the taxes of the wealthy to provide a better social safety net for those who are the poorest.

Nutritional status of elderly people Study by Dr Lita Villalon based on 340 Moncton seniors1

Over 60% of seniors living ate home consume less that the number of food portions recommended by the Canada Food Guide for: Dairy products Fruit and vegettables Cereal products

Nutritional status of seniors (continued)

Calcium, zinc and vitamin D intakes were insufficient in the case of 80% of seniors;

Low intakes of calcium, vitamin D, folates and zinc should concern us;

Calcium, vitamin D and folates are associated with healthy bones and cardiovascular health.

21

Nutritional status of seniors (Continued) Zinc plays an important role in the

immune system; a difficiency may cause alterations in mental capacity, a loss of appetite or diarrhea;

Among the 340 seniors studied, 80% had at least one chronic health problem;

Three health problems or more were noted in 33 %, of the cases.

ConclusionMany individus and families in New Brunswick

do not have enough money to eat healthily.Research shows clearly that low income

people are in poorer health: they are sick more often, levels of infant mortality are higher, life expectancy is shorter, etc.

The negative impacts of malnutrition are carried throughout the life cycle, especially during the senior years.
