ncbi.nlm.nih.gov — Studies of fruit and vegetable consumption in relation to overall health are limited. We evaluated the relationship between fruit and vegetable intake and the incidence of cardiovascular disease and cancer and of deaths from other causes in two prospective cohorts.   A total of 71 910 female participants in the Nurses' Health study and 37,725 male participants in the Health Professionals' Follow-up Study who were free of major chronic disease completed baseline semiquantitative food-frequency questionnaires in 1984 and 1986, respectively. Dietary information was updated in 1986, 1990, and 1994 for women and in 1990 and 1994 for men. Participants were followed up for incidence of cardiovascular disease, cancer, or death through May 1998 (women) and January 1998 (men). Multivariable-adjusted relative risks were calculated with Cox proportional hazards analysis.   Total fruit and vegetable intake was inversely associated with risk of cardiovascular disease but not with overall cancer incidence. Of the food groups analyzed, green leafy vegetable intake showed the strongest inverse association with major chronic disease and cardiovascular disease. Increased fruit and vegetable consumption was associated with a modest although not statistically significant reduction in the development of major chronic disease.   Hung HC, Joshipura KJ, Jiang R, Hu FB, Hunter D, Smith-Warner SA, Colditz GA, Rosner B, Spiegelman D, Willett WC.

scienceblogs.com — In fact, most of the bacteria, fungi, and yeast that inhabit our bodies are either beneficial or neutral; our digestive systems wouldn't function properly without the bacteria that live in our colons. They're responsible for breaking down some polysaccharides, starches, fibers into forms that can be absorbed. Without these wee beasties, there would be a lot of the components of our food that we'd have a hard time absorbing. They even produce some vitamins and facilitate their absorption. But that's not all. The normal gut flora play a major role in preventing infection by crowding out pathogenic bacteria. That's one reason why antibiotics can result in severe diarrheal diseases. They kill off the "good bacteria," leaving the "bad bacteria" to proliferate. They can also stimulate the development of the gut's mucosal immune system. Truly, it is a symbiotic relationship between us humans and our bacterial flora, which colonize our guts shortly after we are born and stay with us for the rest of our lives. by Orac

www8.nationalacademies.org —  African Fruits Could Help Alleviate Hunger and Bolster Rural Development, Environmental Stability in Africa   WASHINGTON -- Africa's own fruits are a largely untapped resource that could combat malnutrition and boost environmental stability and rural development in Africa, says a new report from the National Research Council.  African science institutes, policymakers, nongovernmental organizations, and individuals could all use modern horticultural knowledge and scientific research to bring these "lost crops" -- such as baobab, marula, and butterfruit -- to their full potential, said the panel that issued the report.    Today, tropical fruit production in Africa is dominated by species introduced from Asia and the Americas, such as bananas, pineapples, and papayas.  Because these and other crops arrived on the continent centuries ago already improved through horticultural selection and breeding, they increasingly displaced the traditional species that had fed Africans for thousands of years.  The imported species also received the support of colonial powers who wanted familiar crops that were profitable to grow, and indigenous fruits continued their downward spiral of dwindling cultivation and knowledge.    With renewed scientific and institutional support, however, Africa's native fruits could make a much greater contribution to nutrition and economic development, the new report says.  Fruit trees and shrubs also offer long-term benefits by improving the stability of the environment.   The report highlights 24 fruits that hold special promise; some are already being cultivated in parts of Africa, while others are harvested from the wild.  Examples are:   Aizen.  Giving more people access to this wild fruit -- which grows in extreme climates with few other food resources -- could reduce malnutrition and mortality, the report says.  The fruits are a good source of vitamins A and C, calcium, and some minerals, while the seeds are high in protein and zinc.  This large, resilient Saharan shrub shows promise as a way to protect erodible slopes, stabilize dunes, and create windbreaks.    Balanites.  This small desert tree tolerates heat and aridity so well it thrives deep in the Sahara.  It produces heavy yields of datelike fruits, as well as kernels that are one-half oil and one-third protein -- similar to the makeup of soybeans and sesame seeds.  These fruits and kernels already feed families in arid zones where few other food crops exist, but their full potential is scarcely tapped.  The seeds supply a food-grade vegetable oil also used in local cosmetics and pharmaceuticals.  The trees stabilize the natural environment, helping dry areas resist desertification.   Baobab.  The fruits of the baobab tree contain a sticky pulp that can be dried into a nutritious powder high in protein, vitamins, and minerals.  The powder is stirred into warm water or milk to create a healthy drink, and also beaten and dried into thin pancakes for use months or even years later, aiding food security.  During the rainy season, villagers often store water in the tree's trunk for later use.  The sale of baobab fruits aids rural commerce, and the trees themselves -- which also yield a popular leafy vegetable -- are almost indestructible.   Butterfruit.  This small tree produces fruit that is mainly used as a vegetable.  High in calories and one of the best protein sources in the fruit world, butterfruit is especially promising for reducing child malnutrition.  Even now, these fruits help many communities survive seasonal food shortages in the harshest hot, humid lowlands.  Butterfruit also serves as a cash crop, pouring into cities and rural markets in large quantities.  And the trees, which yield mahoganylike wood, may have potential for plantation forestry.     Ebony.  The ebonies of Africa yield some of the world's finest timber and also bear abundant, bright red fruits that are succulent and sweet. These can be dried for use when seasonal foods become scarce. The seeds of some ebonies are also edible, and the leaves are used as animal feed.  Though the trees are known and valued on a local level, hardly anything scientific is known about managing them as food crops.   Marula.  This tree is a nutritional powerhouse, producing both fruits high in vitamin C and nuts similar to the macademia, high in protein and minerals.  The fruits are popular in markets and even exported, while the kernels contribute to nutrition and food security.  In addition, oils extracted from the nuts are also exported for high-priced skin care products.  Harvesting the fruits and shelling the nuts provide work for thousands of rural women who have hardly any other source of income.     Tamarind.  These fruits are a strong source of B vitamins and calcium, and can be stored for months without refrigeration.  In addition, tamarind's sweet-sour pulp can be preserved in the form of sun-dried cakes -- a simple procedure that perhaps millions throughout Africa could exploit for food security, the report says.  Already widespread, the trees have great promise for restoring damaged lands to health and productivity, and likely for sequestering carbon, since they are treasured and seldom cut down.

ds9.botanik.uni-bonn.de —  ROOT APEX – THE ANTERIOR POLE OF PLANT BODY Root Apices represent the Anterior Pole: Specialized for uptake of nutrients and for neuronal activities. Importantly, new roots are formed endogenously (recapitulation of embryogenesis). Shoot Apices represent the Posterior Pole: Specialized for photosynthesis (which is dispensable in holoparasitic plants like Rafflesia) and for sexual reproduction. The flower is the perfect form of the shoot. Shoots harbor plant organs of excretion, trichomes and hydathodes. Moreover, stomata allow gas exchange. Similarly as sexual organs, also organs of plant excretion and stomata are located at the posterior part of the plant body. Even more, hydathodes seem to function in analogy to kidney (Pilot et al. 2004, Plant Cell 16: 1827-1840). Roots are essential whereas shoots are dispensable: In holoparasitic plants, such as Rafflesia, roots are transformed into haustoria while the green part of the plant is missing completely. Nevertheless, haustoria of Rafflesia form the largest flowers in the plant kingdom which reveals that this unique organism really belongs to plants. AUXIN – PLANT NEUROTRANSMITTER Auxin: Represents a plant-specific neurotransmitter and is transported, in a light- and gravity-dependent manner, preferentially along the anterior-posterior axis of the plant body. Auxin induces the formation of both vascular strands (plant nerves) and roots (which harbour the “serial plant brain”). Roots and Auxin: Root apices represent major sinks for the polar auxin transport. Root apices are extremely sensitive towards externally applied auxin, and lateral root formation is induced by this means. Moreover, auxin rapidly regulates vesicle trafficking and gene expression in roots. Initiation of lateral root primordia is an endogenous process resembling early embryogenesis. In contrast, new shoots and leaves are formed exogenously. CELLULAR END-POLES – PLANT SYNAPSES Plant Synapses: Stable actin-supported adhesive domains (known as end-poles or cross-walls) between adjacent plant cells across which auxin and other chemical signals are transported via actin-based vesicular trafficking pathways. Besides these developmental plant synapses, plants are also capable of forming cell-to-cell junctions with cells of another organisms (plants – fungi – bacteria) corresponding to what is defined as an ‘immunological synapse’. These specialized cell-to-cell adhesion domains involve the plasma membranes of two different organisms opposing each other. Such adhesive domains are also sites of active cell-to-cell transport of molecules and metabolites. VASCULAR STRANDS – PLANT NERVES Vascular Strands: The basic units of the vascular system represent both plant nerves as well as a plant endoskeleton. Leaves contain single strands which combine to form the vascular bundles of the stem, and the vascular cylinder of the root. In roots, the largest portion of the organ is the vascular tissue, and its strands (plant nerves) are supported by numerous cells forming the vascular cylinder. Phloem: Supracellular axon-like ‘channel' interconnecting shoot and root apices. Phloem is specialized for transmission of action-potential-driven electric signals. Axon-like means that it is specialized for the rapid transfer of RNA molecules but does not accomplish ribosome assembly and mRNA translation. Xylem: Non-living and water-filled tubes specialized for transmission of hydraulic signals which are self-transmitting waves induced and driven by changes in hydrostatic pressure. ROOT APICES INTERCONNECTED VIA VASCULAR CYLINDERS – SERIAL NERVOUS SYSTEM OF PLANT Plant Brain: Each root apex harbours a unit of nervous system of plants. The number of root apices in the plant body is high and all brain-units are interconnected via vascular strands (plant nerves) with their polarly-transported auxin (plant neurotransmitter), to form a serial (parallel) nervous system of plants. The computational and informational capacity of this nervous system based on interconnected parallel units is predicted to be higher than that of the diffuse nervous system of lower animals, or the central nervous system of higher animals/humans.

commonfund.nih.gov — Within the body of a healthy adult, microbial cells are estimated to outnumber human cells by a factor of ten to one. These communities, however, remain largely unstudied, leaving almost entirely unknown their influence upon human development, physiology, immunity, and nutrition. To take advantage of recent technological advances and to develop new ones, the NIH Roadmap has initiated the Human Microbiome Project (HMP) with the mission of generating resources enabling comprehensive characterization of the human microbiota and analysis of its role in human health and disease.HMPTraditional microbiology has focused on the study of individual species as isolated units. However many, if not most, have never been successfully isolated as viable specimens for analysis, presumably because their growth is dependant upon a specific microenvironment that has not been, or cannot be, reproduced experimentally. Among those species that have been isolated, analyses of genetic makeup, gene expression patterns, and metabolic physiologies have rarely extended to inter-species interactions or microbe-host interactions. Advances in DNA sequencing technologies have created a new field of research, called metagenomics, allowing comprehensive examination of microbial communities, even those comprised of uncultivable organisms. Instead of examining the genome of an individual bacterial strain that has been grown in a laboratory, the metagenomic approach allows analysis of genetic material derived from complete microbial communities harvested from natural environments. In the HMP, this method will complement genetic analyses of known isolated strains, providing unprecedented information about the complexity of human microbial communities.Scope of the Human Microbiome ProjectBy leveraging both the metagenomic and traditional approach to genomic DNA sequencing, the Human Microbiome Project will lay the foundation for further studies of human-associated microbial communities. Broadly, the project has set the following goals:    * Determining whether individuals share a core human microbiome    * Understanding whether changes in the human microbiome can be correlated with changes in human health    * Developing the new technological and bioinformatic tools needed to support these goals    * Addressing the ethical, legal and social implications raised by human microbiome research.

globalhealingcenter.com — The Benefits of Fruits & VeggiesVegetarians and CancerOther than lowering the risk of cancer, helping to control cholesterol and fat levels, fruits and vegetables provides loads of antioxidants, which help remove free radicals from the body.Free radicals may cause cellular damage and lead to cancer. Free-radical wrangling antioxidants are found in all fruits and vegetables, ... as well as raw nuts and seeds.Common antioxidants are vitamin A, vitamin E, vitamin C, selenium, lycopene, lutein and beta-carotene.Different fruits are higher in different types of antioxidants, so make sure you’re eating a wide variety...Looking for a quick and easy way to pack antioxidants into your diet? Bulk up on healthy berries! Not only do they contain extremely high amounts of antioxidants, they contain phytochemicals. ...Phytochemicals seem to block cancer development, but youll miss out on this important cancer fighting component if you just take an antioxidant supplement instead of consuming phytochemical containing foods, like berries.Blueberries are among the best free radical wranglers on the market, and they’re fun to gather at you-pick-farms.The American Cancer Society Guidelines states that 30-40% of the occurrences of cancer are linked with diet, and therefore preventable.You can decrease your cancer chances even more by eating a raw food diet of fruit, vegetables, nuts and seeds and drinking only water.

uvm.edu —  Ecological economics is a transdisciplinary field of study that broadly examines the relationships between ecological and economic systems. It differs from both conventional economics and ecology by emphasizing environment-economy interactions. Ecological economics is based on the assumption that the economy is a subsystem of a larger ecological life support system. Understanding this relationship is central to meeting humanity's current environmental challenges, as well as building a sustainable future. Ecological economists strive for an ecologically sustainable, socially equitable, and economically efficient future. The Gund Institute represents a commitment to using a transdisciplinary approach to solve real-world problems. Working together, both academics and practitioners can help to develop and implement new environmental policy and management techniques that benefit the environment and the economy, holistically and sustainably.
