What Are Omega - 3 Oils

Back to Nutrition and Wellness


 You hear about them often in the news...omega-3 fatty acids, but do you know what they are? Here are a few key facts about these special fatty acids

  • They are a type of polyunsaturated fatty acids.
  • There are three major types found in foods:
    • alpha-linolenic acid, found in soy products, canola oil and nuts.
    • eicosapentenoic acid, found in fish oil and fatty fish.
    • docosahexenoic acid found in fish oil and fatty fish.
  • Diets that include foods rich in omega-3 fatty acids from marine sources are associated with lower triglyceride levels, which can decrease heart disease risk.
  • Omega 3's also may reduce risk of blood clots, and sudden death in patients who have had a heart attack.
  • To increase consumption of omega 3 fatty acids, include fish in your weekly meal plan.

Have you ever wondered why garlic sometimes turns blue when soaked in vinegar for a while?

Garlic contains sulfur compounds that may react with copper to form copper sulfate, a blue or blue-green compound. The amount of copper needed for the reaction is very small and is frequently found in normal water supplies. Also, garlic bulbs that have not been properly cured before marketing, or bulbs that have been refrigerated, will turn green or blue-green.
