Fatty Acids
Monounsaturated Fats
Heart-healthy fatty acids with a single double bond that support cardiovascular health, metabolism, and cell integrity
Quick Facts
Daily Needs
15-20% of total daily calories from monounsaturated fats is generally recommended as part of a healthy diet
Importance
Monounsaturated fats are beneficial fatty acids that support heart health, improve cholesterol profiles, and provide stable energy while promoting cellular integrity.
Key Functions
- •Heart health support
- •Improved cholesterol profile (raising HDL, lowering LDL)
- •Cell membrane structure and integrity
- •Anti-inflammatory properties
- •Energy storage and provision
- •Vitamin absorption (fat-soluble vitamins)
- •Temperature regulation in the body
- •Support for hormone production
- •Protection of organs
Deficiency Signs
- •No specific deficiency syndrome for monounsaturated fats
- •Low intake may contribute to poorer cardiovascular outcomes
- •Potentially less stable cell membranes
- •Possible increased inflammation with replacement by other fats
- •Potentially higher LDL cholesterol when replaced with saturated fats
Excess Signs
- •Generally well-tolerated even at higher intakes
- •May contribute to excess calorie intake if consumed in very large amounts
- •Excessive calories from any fat source can lead to weight gain
- •Very high consumption may displace other essential nutrients
Best Food Sources
- •Olive oil (especially extra virgin)
- •Avocados and avocado oil
- •Nuts (almonds, hazelnuts, macadamias, cashews, pecans)
- •Olives
- •Peanuts and peanut butter (natural)
- •Sunflower seeds (high-oleic varieties)
- •Canola oil
- •Sesame oil
- •Eggs
- •Poultry (especially dark meat)
Absorption Facts
- •Efficiently absorbed in the small intestine
- •Requires bile salts for emulsification and absorption
- •More stable and less prone to oxidation than polyunsaturated fats
- •Cooking stability is higher than polyunsaturated fats
- •Generally high bioavailability (80-90%)
- •Absorbed alongside other dietary fats
- •Converted to chylomicrons for transport in lymphatic system
Special Considerations
- •Mediterranean diet pattern features high monounsaturated fat intake
- •Quality and source matters - whole foods provide additional beneficial compounds
- •Extra virgin olive oil contains polyphenols with additional health benefits
- •Better choice for cooking at medium temperatures compared to polyunsaturated fats
- •Storage in dark containers helps preserve quality
- •Stable shelf life compared to polyunsaturated fats
- •Phenolic compounds in some sources (olive oil) provide additional benefits beyond the fatty acids themselves
