What are trans-fat or
partially-hydrogenated
butter and lard are solids. Vegetable
oils were cheaper, but as liquids they
were not a suitable alternative. A
chemical process called
hydrogenation was developed that
converts vegetable oils into
saturated, more solid fats (margarine
and vegetable shortening). Partialhydrogenation lowered the content
of saturated fat in vegetable
shortening and margarine, but also
dramatically increased the amount of
a certain kind of fat - trans fat - in
our diets.

Supplements ?
Federal Regulation of Dietary Supplements
 The Federal Government regulates through the FDA. The regulations for dietary
supplements are not the same as those for prescription or over-the-counter drugs.
In general, the regulations for dietary supplements are less strict.

A manufacturer does NOT have to prove the safety and
effectiveness of a dietary supplement before it is marketed. A
manufacturer’s claim must be followed by the words "This

statement has not been evaluated by the U.S. Food and Drug
Administration (FDA). This product is not intended to diagnose,
treat, cure, or prevent any disease."
Manufacturers are expected to follow certain "good
manufacturing practices" (GMPs) to ensure that dietary
supplements are processed consistently and meet quality
standards.
 Once a dietary supplement is on the market, the FDA
monitors safety. If it finds a product to be unsafe, it can take
action against the manufacturer and/or distributor, and may
issue a warning or require that the product be removed from
the marketplace.

High-fructose corn syrup

High-fructose corn syrup is a common sweetener and preservative.
High-fructose corn syrup is made by changing the sugar (glucose) in
cornstarch to fructose — another form of sugar. The end product is a
combination of fructose and glucose. Because it extends the shelf life of
processed foods and is cheaper than sugar, high-fructose corn syrup
has become a popular ingredient in many sodas, fruit-flavored drinks
and other processed foods.
Standard HFCS comes in 3 varieties: HFCS 90
which is approximately 90% fructose and
10% glucose; HFCS 55 which is
approximately 55% fructose and 45%
glucose; and HFCS 42 which is approximately
42% fructose and 58% glucose.

the National Organic Standards Board of the USDA
established a national standard for the term
"organic."

"Organic" does not mean "natural.“

There is no legal definition as to what
constitutes a "natural" food.

However, the food industry uses the term
"natural" to indicate that a food has been
minimally processed and is preservativefree.

Natural foods can include organic foods, but
not all natural foods are organic.
NATURAL?
YES

?
No preservatives
Min. Processing
 Organic
food, defined by how it can
NOT be made rather than how it
can be made:
must be produced without the
use of sewer-sludge fertilizers,
most synthetic fertilizers and
pesticides, genetic engineering
(biotechnology), growth
hormones, irradiation or
antibiotics
