Functional foods are specially designed or modified foods that provide additional health benefits beyond the basic nutritional value. These benefits often come from added nutrients such as vitamins or minerals, and bioactive compounds like antioxidants, probiotics, or plant sterols.
Categories of Functional Foods
Functional foods can be classified into two main categories:
- Naturally Occurring Functional Foods: These foods naturally contain bioactive compounds offering health advantages. Examples include berries, nuts, fish, and whole grains.
- Manufactured Functional Foods: Carefully formulated or modified foods containing specific health-boosting ingredients. Examples include fortified breakfast cereals, energy bars, and probiotic yogurt.
Health Benefits and Examples
Functional foods are revered for their health-enhancing properties. Here are some examples:
- Probiotics: Found in yogurt, kefir, and sauerkraut, these live bacteria support gut health and boost the immune system.
- Omega-3 Fatty Acids: Present in fatty fish, flaxseeds, and chia seeds, they help reduce inflammation and improve heart health.
- Fiber: Found in fruits, vegetables, and whole grains, fiber aids digestion and decreases risks related to heart disease and diabetes.
- Antioxidants: Available in foods like berries, dark chocolate, and green tea, antioxidants reduce inflammation and oxidative stress.
