In
recent years, consumers have begun to look at herbal products and
traditional herbal medicines to treat several medical disorders
and maintain health. This move, away from accepted medical practices
into those that are less well documented, is not confined to herbal
remedies, but is part of a larger interest in a variety of compounds
which may confer health benefits when consumed and which are present
in plants of many kinds, including common fruits, vegetables, grains
and spices.
What
is known of the beneficial effects of accepted nutrients is being
supplemented with information on other compounds present in plant
products. There is likely to be an explosion of knowledge about
the constituents of plants in the next few decades. The consumer
market for functional foods and neutraceuticals is expected to grow
substantially worldwide by 2005.
At
the retail level, the global market for natural health care and
functional food products is currently estimated at $ 62 billion.
The market is growing at 10 per cent every year, and is projected
to touch $ 160 billion by 2010. The United States market is more
than $ 28 billion, and grew at 11 per cent for two years in a row.
Of the total global botanical business, extracts contribute $ 6.2
billion. Of this, India accounts for $ 100 million, China for $
500 million and Thailand $ 250 million.
The
market is upbeat about the potential of neutraceuticals. The industry
must provide products that address most, if not all, of the healthcare
needs of the market. Traditionally, medicinal plants were always
collected. It has now become necessary to cultivate them for commercial
purposes. For this, it must retrieve information from the original
texts, assess the availability of flora and its sources, protect
threatened plant resources and develop systems for their cultivation,
standardise the methods for processing of raw material, improve
the research facilities, develop efficient testing procedures, and
develop a system of drug delivery and formulations.
A
“functional food” is similar in appearance to a conventional food
that is consumed as a part of the usual diet, but has certain physiological
benefits and/or reduces the risk of chronic disease beyond basic
nutritional functions. For example, low saturated fat margarine,
soy-based products (meat and dairy replacements), flax bread, breakfast
cereals containing granola oat and soy protein clusters, milk containing
higher levels of calcium, and yoghurt with acidophilis and bifidum
cultures.
A
“neutraceutical” is a product isolated or purified from foods and
generally sold in medicinal form not usually associated with food.
A neutraceutical has physiological benefits and provides protection
against chronic diseases. For example, vitamin pills and concentrated
forms of specific herbs and other plants.
