Bars with extra protein, coffee with collagen, fiber-enriched granolas. It's not a passing fad — it's functional food, and it's changing the way we think about food.
Functional food is not supplementation in disguise — it's real food, designed to offer more than just energy. This guide explains what the concept truly means, what science says, and how you can practically integrate it into your routine. Based on scientific evidence and without promises that EFSA does not approve.
1. What are functional foods?
Functional foods are food products that, in addition to nourishing, contain bioactive ingredients with demonstrated beneficial effects on health. They are not supplements — they are real food, formulated to offer more than the basics.
The concept originated in Japan in the 1980s, when the government created the FOSHU (Foods for Specified Health Uses) category. Since then, Europe and the United States have developed their own regulatory frameworks. In the EU, Regulation (EC) 1924/2006 defines which nutritional and health claims can be used — and EFSA (European Food Safety Authority) validates the scientific evidence behind each one.
According to a review published in the journal Nutrients (MDPI, 2024), functional foods can play a relevant role in preventing nutritional deficiencies and promoting metabolic health when integrated into a balanced diet.[1]
It is important to distinguish between proven facts and empty promises. EFSA-approved claims — such as "protein contributes to the growth and maintenance of muscle mass" or "oat fiber contributes to an increase in faecal bulk" — have a solid regulatory and scientific basis. Generic claims such as "superfood" or "detox" have no such basis.
- "Protein contributes to the maintenance and growth of muscle mass" — Protein Pancakes, Protein Oats, Coffee with Collagen
- "Protein contributes to the maintenance of normal bones" — collagen drinks
- "Oat beta-glucans contribute to the maintenance of normal blood cholesterol levels" — Protein Oats, Gut Granola
- "Fiber contributes to normal bowel function" — Gut Granola (19g fiber/100g), Protein Oats
- "Caffeine contributes to increased alertness" — Coffee with Collagen (≥75mg caffeine)
- "Vitamin C contributes to normal collagen formation for the normal function of skin" — Barley with Collagen
2. The 3 trends that define 2026
The "Protein-Plus" trend reflects the demand for products that combine high protein content with additional functional ingredients. It's not enough to have protein — consumers want protein with collagen, with creatine, with fiber. It's the convergence of performance and everyday nutrition.[2]
The concept of "fibermaxxing" — the conscious effort to meet or exceed the recommended daily fiber intake — gained traction in 2025–2026. With growing awareness of gut health, high-fiber products (such as functional granola or protein oats) are among the most sought after.[3]
Ingredients such as caffeine (EFSA-approved claim for alertness and concentration), L-theanine, and creatine are gaining ground in everyday foods — from functional coffee to energy bars. Cognitive nutrition has moved from a niche to mainstream.
3. How to integrate into your routine — without revolutionizing anything
You don't need to revolutionize your diet. A few targeted swaps make a difference — in less than 5 minutes of preparation per meal:
CORIAL Instant Protein Oats have 30g of protein and 6g+ of fiber per 100g — "high in protein" and "high in fiber" according to Reg. (EC) 1924/2006. Ready in 90 seconds.
CORIAL Coffee with Collagen combines caffeine with 85% hydrolyzed collagen. Same preparation time, much more nutrition.
CORIAL Protein Pancakes have 39g of protein per 100g — the same ritual, with double the nutrition.
CORIAL Gut Granola has 19g of fiber per 100g (including prebiotic chicory inulin). Combined with yogurt, it creates the most accessible synbiotic effect available.
Functional foods are not magical. The benefits are real but specific — and depend on dosage, consistency, and dietary context. A product with an EFSA-approved claim offers real transparency. A product that promises "detox" or "fat burning" has no regulatory or scientific basis. CORIAL only communicates what has been validated — because we believe that honesty is also part of the product.
Functional foods that deliver what they promise — regulated by EFSA
Each CORIAL product has been formulated with ingredients with demonstrated effects and approved claims. No "superfoods", no "detox", no promises that science does not support.
