Bioactive compounds (BCs) are naturally occurring chemicals found in small amounts in plants, animals, and fermented foods that positively impact physiological functions and promote health. Unlike essential macronutrients and vitamins, they are not strictly required for basic survival but actively modulate metabolic processes to help prevent chronic diseases.
Key Types & Sources
- Polyphenols: Powerful antioxidants found in fruits, vegetables, green tea, and red wine that reduce inflammation and lower cardiovascular risk.
- Carotenoids: Plant pigments (beta-carotene, lycopene) found in carrots and tomatoes that support eye health and combat oxidative stress.
- Bioactive Peptides: Specific protein fragments found in dairy, fish, and legumes that help regulate blood pressure and immune functions.
- Organosulfur Compounds: Found in garlic and onions, these are known to help lower cholesterol and regulate blood pressure.
- Omega-3 Fatty Acids: Bioactive lipids found in fatty fish and flaxseed, essential for brain and heart function.
Primary Health Benefits
Bioactive molecules are increasingly recognized in functional foods, nutraceuticals, and preventative medicine. Their primary functions in the body include:
- Antioxidant activity: Neutralizing free radicals that cause cellular damage and aging.
- Anti-inflammatory properties: Suppressing pathways that lead to chronic conditions like obesity and diabetes.
- Cardioprotective effects: Improving blood flow and reducing LDL (bad) cholesterol.
- Immune modulation: Supporting the body's natural defense and metabolic systems.
