Fat is a required nutrient in
our diet. Together with protein and carbohydrate, fat is one
of the three macronutrients in the diet. Fat is required for
the absorption of fat–soluble vitamins A, D, E and K,
and helps protect internal organs including the liver and kidneys.
It is a key element in the cells of our nerves, brain and spinal
cord. It also plays a role in temperature regulation. All fats
are not created equal and some are better for you than others.
The key with fat is striking the right balance with
healthy fats and avoid eating too much.
Omega-3 Fatty Acids: Some of the best quality
fats include those found in fish and fish oils, known as
omega–3 fats. Other fats in the omega–3 family
are present in plant foods, such as flaxseeds, walnuts, canola
oil and soy products. Studies have shown that these fats
help reduce the risk of heart disease by reducing total
and LDL (bad) cholesterol levels. Choose these quality fats
more often.
Monounsaturated and Polyunsaturated Fats: These
fats are from plant products and are generally liquid at
room temperature. Monounsaturated fats,
found in olive oil, canola oil, nuts, seeds and even avocado,
provide quality fats to a healthy diet. Polyunsaturated fats
are found in safflower, sunflower, corn and soybeans oils, fish,
nuts and seeds. When substituted for saturated fats, these
unsaturated fats have been shown to protect against chronic
disease.
Saturated Fats: These are found mainly
in animal products and are hard at room temperature (e.g. butter,
lard, and the white fat in meat). Choose foods with minimal
amounts of saturated fats including lower fat dairy products, lean
meats and poultry.
Hydrogenation and Trans Fatty Acids: Hydrogenation
is a process used in making some types of margarines and
other processed food products. It changes a liquid oil into
a solid fat. During the process of hydrogenation, trans fatty
acids are formed. Research indicates that trans fatty acids
have a negative impact on health. Processed fats, such as
hydrogenated and trans fats, should be kept to a minimum. |
