During the 90′s it was all about no-fat or low fat.The millennium ushered in a bunch of new names, for fat. ·Saturated

  • Unsaturated
  • Heart healthy
  • Good fat

Fat got a bad reputation in the 90′s and we now need to unlearn all the bad things we heard about fats.

If it wasn’t for fats,

  • Our cells would have no membranes
  • There would be no shape to our cells
  • Nutrients could not move in or our of our cells
  • Fat soluble vitamins could not be absorbed
  • Cholesterol would go unregulated
  • Our bodies wouldn’t have protection from the cold

There are 3 types of fats:

  • Saturated fats typically are solid at room temperature.These types of fats don’t break down in the body.Our body doesn’t know what to do with these types of fats and puts them into fat storage.On the way to storage, these fats, float through the blood stream leaving behind a waxy coating, plaque, on the arteries.You guessed it. An eating program that is high in saturated fats, can significantly contribute to heart disease and blood pressure problems.
    • Examples:
      • Palm and palm kernel oils
      • Fast food or processed foods
      • Meat, poultry, and dairy products
  • Unsaturated fats come in 2 categories
    • Mono at the molecular level these fats have a double bond to attached to carbon.These fats remain liquid at low temperatures, eaten in moderation can help reduce the LDL (bad cholesterol) levels.
      • Examples
        • Olive oil, peanut oil and canola oil
    • Poly at the molecular level these fats have more than one double bond attached to carbon.
      • Examples
        • Corn oil, safflower oil, soybean oil, and sunflower oil
  • Essential Fatty Acids (EFAs) are needed to help our bodies to run correctly.These fats should be included in a healthy eating program.Our bodies cannot produce these fats, so we must rely on food. Most often EFAs are referred to as:
    • Omega 6 is best known to:
      • Lower blood cholesterol
      • Assist with skin disorders
        • Good sources include:

·Oils from sunflower, safflower, corn, sesame, poppy, wheat germ, soybean and walnut ·Wheat germ ·Vegetables ·Sunflower, sesame, poppy seeds, pumpkin seeds and walnuts ·Grains ·Legumes

  • Omega 3 is known for its:
  • Anti-inflammatory benefits
  • May help prevent heart disease
  • Thins the blood
  • Trans fats were invented by the food industry to increase the shelf life and taste of food.By adding one hydrogen molecule to vegetable oil, a relatively healthy fat and transforms it into artery clogging fat.When you read your food labels and see anything that uses the word hydrogenation that is a signal that it’s a made with trans fats.
    • Why does this matter?The body processes trans fats like a saturated fats.Trans fats can also contribute to increase cholesterol levels and heart problems.

Effective January 1, 2006 all foods containing trans fats must list them separately on food labels.Why does this mean?

For the first time consumers will know what amounts of saturated fat, cholesterol and trans fats are contained within the foods they eat.This will also give you the information you need to make informed decisions to help reduce your risks of heart problems through a healthy eating program.Did you know that some of your favorite protein bars, shakes, and supplements could contain high amounts of these?If a product includes more than .5 grams of trans fat they will be required to remove it or list on the label.Source of fats.[ii]
