Yogurt, which has lactobacillus bacteria, contributes to improving the quality of intestinal microflora. However, the functional food is mostly attributed to possess "credence attributes" that is the product attributes cannot be claimed directly by the consumers. Such a factor is expected to critically affect the global industry over the forecast period. Labeling on a product might claim that it constitutes extra dosage of calcium, which helps in preventing osteoporosis disease. However, consumers are unable to evaluate such claims as the nutrients cannot be smelled or tasted and do not have any proper shape. Consumers need to wait for a particular period to validate the credence claims. Nevertheless, researchers have been trying to combine functional food and molecular nutrition into one which is anticipated to challenge the traditional diet paradigm. The benefits claimed for functional foods by manufacturers slowly arrive on the plates of the consumers. Speeding the health benefit arrival requires more innovative approaches and also funding to expand the knowledge base associated with molecular nutrition.
