Functional Ingredient Spotlight: Turmeric

We choose what we eat for a variety of reasons: taste, convenience, cost, and health concerns. Food manufacturers capitalize on consumers’ desire for healthy foods by adding ingredients that are marketed to help protect our immune system, improve mood, and increase energy levels.

According to a market analysis report, these added ingredients, known as functional ingredients, are expected to grow by 6.4% annually over the next seven years. While whole foods like fruit, vegetables, and whole grains are essential for good health, today’s consumers are shifting toward fortified convenience foods and beverages that contain functional ingredients. 

Three popular functional ingredients you’ll find in various foods and beverages are turmeric, collagen, and green coffee extract.

Let’s talk about turmeric…

Tumeric is a plant native to Southeast Asia, primarily India, where it is used as both a spice and also traditional medicine for skin disorders, joints, digestion, and upper respiratory tract issues. Curcumin is the primary component of turmeric that provides both the yellow color and the health benefits.

Snacks with turmeric or curcumin in the ingredient list accounted for 9% of all new turmeric product launches in both 2015 and 2019. Frozen breakfasts, microwaveable meals, and tea/juices are other popular foods to which food manufacturers add turmeric in order to boost consumer appeal.

Research shows that curcumin may reduce the risk of cardiovascular disease and diabetes by reducing inflammation and oxidative stress. There’s also some research that shows curcumin may help improve memory and mood by modulating serotonin and dopamine production. However, the amount of turmeric or curcumin used as a functional ingredient is typically much smaller than the dose used in research studies so there is no way of knowing if there is any health benefit.
