Functional foods are those that, regardless of their nutritional value, exert a health benefit, either improving it or reducing the risk of contracting a certain disease.
The conditions that a food must meet to be classified as functional are that it is safe and that there is scientific evidence of the benefits it brings to health in certain age groups.
Food and health authorities around the world demand that consumers consume these foods as part of a balanced diet and in no case a substitute for it.
One type of functional food is called "probiotics", preparations containing microorganisms in sufficient quantity to alter the microflora of the intestine and facilitate intestinal transit. In this way, they exert the beneficial effect.
We have the probiotics available in the market in yogurts, other dairy products and fruit juices, preferably.
The benefits that can be obtained with the administration of probiotics depend on the number of agents, doses and characteristics of the person taking them.
The most commonly used probiotics are bacteria capable of producing lactic acid: lactobacilli and bifidobacteria.
More examples of functional foods, in addition to probiotics, are eggs enriched with essential omega-3 fatty acids to reduce cardiovascular problems, and butters enriched with phytosterols to reduce cholesterol. "
