Document Summary
Triglycerides are the major form of lipid in food and in body. Short chain triglycerides: the more liquid fats at room room temp, the more soluble they are in water, have fewer than 6 carbon atoms (ex: vinegar (acetic acid)) Medium chain: 6-12 carbon atoms, ex: tropical oils, milk. Omega 6 refers to where the first double bond is. Our bodies can put a double bond in 9 position, but we cannot put a double bond in the. Or we cannot out a double bond in the 3 position. So we need to start out with these precursors. What are the sources of these types of fatty acids: we think of animal fat = saturated. But the highest amount of saturated fat is tropical oils (coconut oil). They"re oils bc medium length: monounsaturated fat; biggest source is olive oil. Canola oil and nuts are also quite good sources.
