INTRODUCTION
Plants are the foundation for a significant part of human medicine and for many of the most widely used drugs designed to prevent, treat, and cure disease. A number of our cultivated crop plants, including many vegetable crops, were domesticated for medicinal purposes prior to their current use as food.
PERCEPTIONS OF VEGETABLES IN THE US
Vegetable crops were widely cultivated by native Americans for many centuries prior to the arrival of European settlers in the early 17th century. Vegetables were also a staple of these immigrant Puritans and Pilgrims, who settled the territories that later became the US.
VEGETABLE CROPS AND MEDICINAL PROPERTIES
Taking a step back from modern times, it is important to note that many vegetable crops have been used for medicinal purposes in addition to their use as food for thousands of years (Janick 2002).
THE BEGINNINGS OF FOOD FUNCTIONALITY
Prior to the first decade of the 20th century, nutritional scientists represented their field in several simple categories. This often included carbohydrate or starch, protein, fat, and mineral components, but little else, as vitamins had yet to be discovered (Welsh et al. 1992).
VITAMINS, VEGETABLES, AND LAND GRANT INSTITUTIONS
Throughout the 20th century, the land grant institutions played a major role in elucidating the healthful properties associated with vegetable crops.
VEGETABLES AND HEALTH: PERSPECTIVE FOR THE 21ST CENTURY
A tremendous diversity of dietary patterns exists among human cultures. At first, it is likely that dietary patterns were based simply on survival, or avoiding starvation. As human societies developed agricultural practices, and both trade, and industrialization became commonplace, dietary patterns may have been also been influenced by economics.
Overview
Phytochemicals are chemical compounds produced by plants, generally to help them resist fungi, bacteria and plant virus infections, and also consumption by insects and other animals. The name comes from Greek φυτόν (phyton) 'plant'. Some phytochemicals have been used as poisons and others as traditional medicine.
Definition
Phytochemicals are chemicals of plant origin. Phytochemicals (from Greek phyto, meaning "plant") are chemicals produced by plants through primary or secondary metabolism. They generally have biological activity in the plant host and play a role in plant growth or defense against competitors, pathogens, or predators.
Phytochemicals are generally regarded as research compounds rather than essential nutrients b…
History of uses
Without specific knowledge of their cellular actions or mechanisms, phytochemicals have been used as poison and in traditional medicine. For example, salicin, having anti-inflammatory and pain-relieving properties, was originally extracted from the bark of the white willow tree and later synthetically produced to become the common, over-the-counter drug, aspirin. The tropane al…
Functions
The phytochemical category includes compounds recognized as essential nutrients, which are naturally contained in plants and are required for normal physiological functions, so must be obtained from the diet in humans.
Some phytochemicals are known phytotoxins that are toxic to humans; for example aristolochic acid is carcinogenic at low doses. Some phytochemicals are antinutrients that interfere with the …
Consumer and industry guidance
While health authorities encourage consumers to eat diets rich in fruit, vegetables, whole grains, legumes, and nuts to improve and maintain health, evidence that such effects result from specific, non-nutrient phytochemicals is limited or absent. For example, systematic reviews and/or meta-analyses indicate weak or no evidence for phytochemicals from plant food consumption having an effect on breast, lung, or bladder cancers. Further, in the United States, regulations exist to limit th…
Effects of food processing
Phytochemicals in freshly harvested plant foods may be degraded by processing techniques, including cooking. The main cause of phytochemical loss from cooking is thermal decomposition.
A converse exists in the case of carotenoids, such as lycopene present in tomatoes, which may remain stable or increase in content from cooking due to liberation from cellular membranes in the cooked food. Food processing techniques like mechanical processing can also free carotenoi…
