Lesson objective
You will understand what
micronutrients are and why
the body needs them.
Success criteria
Build - To list and discuss the
micronutrients and write notes
describing how they help the body.
Apply - You have used the body
form to list how and what they do
to help the body say healthy.
Apply - You have listed three
recipes or snacks that are rich in
micronutrients.
Secure - You have filled in the
vitamin and mineral chart ready to
revise why we need micronutrients
Tasks
1. Discuss what can happen to
the body if we have a
micronutrient deficiency
2. Draw out the body form and
list what each micronutrient
does for our bodies
3. Find three recipes that have
a high level of
micronutrients in them and
state which ingredients
4. Finally, fill in the chart for
each vitamin and mineral and
list different fruit and
vegetables that contain
micronutrients

The Physics of Free Radicals
• At the molecular level, biochemistry becomes physics.
The atoms in a chemical bond share a pair of
electrons that create a magnetic attraction. These
atomic bonds are constantly breaking and reforming.
• When a bond breaks, each atom reclaims its electron
and briefly becomes a free radical, an unstable
molecule that immediately seeks to pair up with
another atomic partner.

micronutrients are and why the body
needs them.
Combating Radical Oxidants
with Antioxidants
• Antioxidants (anti-oxygen) are your first line of
defense against free radicals. Free radicals are a
normal part of metabolism and play a vital role in
many biochemical processes, but they must be kept
under control.
• To counteract these radical oxidants, the brain needs
an ample supply of antioxidants. Basically,
antioxidants are molecules that free radicals find
more attractive than cellular components.

Eating fruits and vegetables
• "Eating fruits and vegetables is better than taking a
vitamin pill," according to Rui Hai Liu, assistant
professor of food science. His team found that
vitamin C is only responsible for a small portion of the
antioxidant activity.
• Instead, almost all of this activity in apples is from
phytochemicals. Eating 100 grams of fresh apple with
skins provided the total antioxidant activity equal to
1,500 milligrams of vitamin C.
