Nutrient requirements for optimum health and function of aging physiological systems often are
quite distinct from those required for young ones. Recognition and understanding of the special
nutrition problems of the aged are being intensively researched and tested, especially due to the
increases in the elderly in the general population. In developed countries, economic restrictions and
physical inactivity during aging can significantly reduce food intakes, contributing to nutritional
stresses and needs. Many disease entities and cancers are found with higher frequency in the aged.
The vitamins are a chemically disparate group of compounds whose only common
feature is that they are dietary essentials that are required in small amounts for the
normal functioning of the body and maintenance of metabolic integrity.Metabolically,
they have diverse functions, such as coenzymes, hormones, antioxidants,
mediators of cell signaling, and regulators of cell and tissue growth and differentiation.
It has been recognized for many years that states of nutrient deficiency are associated
with an impaired immune response and with increased susceptibility to infectious
disease. In turn, infection can affect the status of several nutrients, thus setting
up a vicious circle of under nutrition, compromised immune function and infection.
Plant response to reduced water availability and other abiotic stress (e.g. metals) have
been analysed through changes in water absorption and transport mechanisms and
also by molecular and genetic approach. A relatively new aspects of fruit nutrition are
presented in order to provide the basis for the improvement of some fruit quality
traits. The involvement of hormones, nutritional and proteomic plant profiles together
with some structure/function of sexual components have also been addressed.
The first edition of Food Lipids was published in 1998 and the second edition in 2002 by Marcel
Dekker, Inc. Taylor & Francis Group, LLC, acquired Marcel Dekker and the rights to publish the
third edition. We firmly believe that this book has been of interest and will help those involved in
lipid research and instruction. Many have bought the previous editions and we thank you for your
support. The need to update the information in the second edition cannot be overstated, as more data
and new technologies are constantly becoming available.
The mushroom is the fruiting body of the macrofungi. Approximately 14,000 described species of
fungi produce fruiting bodies that are large enough to be considered mushrooms using our definition,
which states that “the mushroom is a macrofungus with a distinctive fruiting body that can be either
epigeous (aboveground) or hypogeous (underground) and large enough to be seen with the naked
eye and to be picked by hand.” According to this definition, in contrast to other definitions,
mushrooms can be Ascomycetes, grow underground, have a nonfleshy texture, and need not be
This book is for anyone who wants an understanding of the fascinating role vitamins
and minerals play in nutrition. It can be used as a supplementary textbook for
nutrition classes, as a self-learning guide, and as a refresher for health professionals.
This book broadens and explains the vitamin and mineral information found in
standard nutrition courses.
Throughout the text are many figures, graphs, and tables that visually display
information and relationships. If you have not taken a class in biochemistry, then
this will be an interesting and relevant way to be introduced to it....
In the past few years, the word superfruit has blared into the headlines
with alluring fanfare. What began as just a few curious exotic
juices in the American market has now evolved into thousands of products
in a multibillion-dollar global industry. From the start, the superfruit
category has been more about marketing than science. Beverages
made from rare, enchanting fruit species marketed with a message of
antioxidant benefi ts have beckoned consumers with a seductive array of
irresistible health promises....
ore and more consumers are looking for health benefits associated with their food or drink product; these concerns range from the effects of probiotics, the health benefits associated with a meat-reduction diet to the role of antioxidants in ageing and skincare. New Profit Opportunities in Health and Nutrition to 2009: Changing consumer concerns and market influencers in food and drinks reveals consumers' health concerns and the relationship between nutrition and purchasing habits.
(BQ) Part 2 book "Textbook of biochemistry" presents the following contents: Electrolyte and water balance, metabolic diseases, free radicals and antioxidants, mineral metabolism and abnormalities, energy metabolism and nutrition, nucleotides chemistry and metabolism,... Invite you to consult.
The development of the strategy has been based on a number of guiding principles. Primarily
the strategy recognises the basic human right to adequate food and health and freedom from
malnutrition and disease. It respects the humanitarian principle of ‘do no harm’ such that its’
implementation should not exacerbate or worsen the situation.
A key guiding principle is recognition of the specific context and challenges of implementation

Engineering and Food for the third millenniumthat is compliant with the requirements
of globalization and new technologies, is one of the most significant additions to the
Food Preservation Technology Series. This bookis the result of a tremendous effort by
the authors, the publisher and editors to put together, as never before, a comprehensive
overview on what is current in food engineering.
Plants are sessile organisms and as such must have mechanisms to deal with both abiotic
and biotic stresses to ensure survival. The term “abiotic stress” includes many stresses
caused by environmental conditions such as drought, salinity, UV and extreme
temperatures. Due to global climate change it is predicted that abiotic stresses will increase
in the near future and have substantial impacts on crop yields (Intergovernmental Panel of
Climate Change; http://www.ipcc.ch).
