How to tell hard-boiled egg
from raw egg?
• Spin a hard-boiled egg and a raw egg
carefully on a countertop. The hardboiled egg will spins but the raw one
will not spin. This is because the hardboiled egg is solid so everything spins
in one direction, while the inside of
the raw egg sloshes in different
directions and, therefore, doesn't
allow it to spin.
Good for your brain
• Eggs give us brainpower. Choline, a
substance found in egg yolks, stimulates
brain development and function.
• Choline has been recognized as an
essential nutrient by Health Canada.
Since it is necessary for good health,
but is not produced by our body in
adequate amounts, a continuous new
supply must be provided by our diet.
Two large eggs provide an adult with
the recommended daily intake of
choline.
