Why protein and gut health are reshaping the future of food globally

Demand for functional foods is surging worldwide as more people turn to nutrition for long-term health. Consumers now prioritise protein not just for muscle growth but for energy, satiety, and general well-being. This shift is reshaping the food industry, with younger generations leading the charge for meals that support digestion and daily wellness.

The global functional foods market is set to expand rapidly, growing from $246.5 billion in 2025 to an estimated $419.1 billion by 2035. Nearly 60% of consumers now actively seek out protein-rich foods, viewing them as essential for overall health rather than just fitness goals. Alongside protein, fibre, fresh produce, and gut-friendly ingredients are becoming staples in balanced diets.

Younger shoppers, particularly Gen Z and millennials, are driving this trend by treating food as part of their wellness routines. They prefer functional nutrition over traditional supplements, looking for benefits like improved gut health, mental clarity, and lasting energy. This preference is reflected in rising sales of probiotics, prebiotics, and other digestive health products.

The Asia-Pacific region is leading the way, with the highest demand and fastest growth for functional foods in 2024. Affordable options, such as probiotic dairy in developing markets, have made these products accessible to more consumers. Meanwhile, in the US, there's a growing appetite for meals that boost strength, aid digestion, and promote long-term wellness.

Globally, 59% of consumers now recognise gut health as a key factor in overall well-being. This awareness is pushing the market for digestive health products upward, with probiotics and prebiotics seeing particularly strong demand.

The shift toward functional foods shows no signs of slowing, with protein and gut health at the forefront of consumer priorities. As demand grows, the market is expected to expand significantly over the next decade. Brands and producers are responding by offering more products that combine nutrition with everyday wellness benefits.
