Functional foods are those that provide health benefits beyond basic nutrition, such as reducing the risk of chronic diseases or improving cognitive function.

Kale is rich in antioxidants and fiber, salmon is a good source of omega-3 fatty acids, and yogurt contains probiotics that support gut health.

Functional foods contain bioactive compounds, such as antioxidants, phytochemicals, and prebiotics, that interact with the body's systems to promote health.

Functional foods have been shown to have a variety of health benefits, including reducing the risk of chronic diseases, improving cognitive function, and boosting immunity.

Functional foods are not a replacement for a balanced diet, which should include a variety of nutrient-rich foods from all food groups.

To incorporate more functional foods into your diet, aim to eat a variety of fruits and vegetables, choose whole grains over refined grains, and consume fermented foods.

White bread is a refined grain and does not contain the same health-promoting compounds as functional foods.

There is no specific recommended daily intake of functional foods, as the amount that is beneficial for an individual will depend on their dietary needs and overall health.

To learn more about functional foods, it is best to talk to a healthcare provider or registered dietitian, read books and articles about functional foods, and search for information online.
