There are three main types of fatty acids: saturated, monounsaturated and polyunsaturated. All fatty acids are chains of carbon atoms with hydrogen atoms attached to the carbon atoms.
1. Monounsaturated fats are found in high concentrations in:
Olive, peanut, and canola oils
Avocados
Nuts such as almonds, hazelnuts, and pecans
Seeds such as pumpkin and sesame seeds
2. Polyunsaturated fats are found in high concentrations in
Sunflower, corn, soybean, and flaxseed oils

Flax seeds
Fish
