How Old Are You? The Physical
Effects of Ageing
True or False?
North Americans spend billions of dollars each year on
cosmetic methods (including creams, treatments and
surgery) to achieve &/or maintain a youthful
appearance.
TRUE. North Americans spend excessive time and money
on costly products, procedures and treatments to
maintain youthful skin.
An example of this are anti-cellulite creams which simply
smooth the skin’s surface temporarily and does not have
any long-term effect. A well balanced & nutrient dense
diet can deter the accumulation of fatty deposits in the
skin which would eliminate the need for expensive
creams.

showing the effects of increasing age” is

other chronic diseases can all cause physical
changes on the skin such as discoloration and
swelling, thinning and brittle hair and nails, and

illnesses, but can also lead to a healthier,

Vitamin A is a fat soluble vitamin which protects
cells from everyday damage. Also known as
part of the antioxidant group, Vitamin A can be
found in foods such as tomatoes and red
berries. Our bodies benefit both internally and
externally from this valuable vitamin, including
our bodies’ largest organ. Name this organ.
SKIN. Your body’s largest organ requires this
nutrient to keep hair, nails and skin looking its
best. Deficiencies in Vitamin A can result in
brittle nails, loss of hair, skin irritation and
redness among other more serious problems.

Broccoli
Spinach
yogurt
consuming a minimum of 1200mg of Ca
each day can help your body prepare for
the ageing process, as ageing bones are
susceptible to osteoporosis, cracking and
brittle teeth and an outward appearance
of frailty.
True or False?
Dehydration causes lack of vitamin uptake within
the body leaving an appearance of dry and pale
skin leading to fine lines and wrinkles.
TRUE. Lack of water can cause a build up of
toxins in the body which can lead to many
serious problems. Keeping the body hydrated
also allows transport of important nutrients
throughout the body. Water also plays a role in
skin firmness and elasticity as it supplies your
skin with the nourishment it needs to look its
best. This can lead to clearer, brighter and more
supple skin, as well as contribute to the
prevention of premature wrinkles.

decrease, also decreasing our appetites.

amounts of nutrients to maintain itself and
ward off disease and illness. One way to
achieve this balance is through:
?
Nutrient dense foods.
In Conclusion
The aging process cannot be stopped, but
premature signs of aging can be lessened.
Key factors in preventing the premature
signs of aging can include physical activity,
education and awareness, as well as good
nutrition.
