To understand nutrition a nutritionist must keep an open mind and be familiar with many of the disciplines that impact on or are influenced by nutrition. The following is an incomplete list:
· Soil and plant sciences
o Factors that impact on nutrient availability
· Animal science:
o environment, climate, housing
o water quality and supply
· Veterinary Medicine
o livestock and pet wellness
o physiology and patho- physiology
· Cellular biology
The following definitions apply to the topics that I will be covering in this paper (These definitions with much more detail can be found in Wikipedia):
o “Functionally relevant changes to the genome that do not involve a change in the nucleotide sequence. Examples of mechanisms that produce such changes are DNA methylation and histone modification, each of which alters how genes are expressed without altering the underlying DNA sequence. Gene expression can be controlled through the action of repressor proteins that attach to silencer regions of the DNA. These epigenetic changes may last through cell divisions for the duration of the cell's life, and may also last for multiple generations even though they do not involve changes in the underlying DNA sequence of the organism instead, non-genetic factors cause the organism's genes to behave (or "express themselves") differently”
o the scientific study of the interaction of nutrition and genes, especially with regard to the prevention or treatment of disease
o The scientific study of the set of metabolites present within an organism, cell, or tissue.
o is the "systematic study of the unique chemical fingerprints that specific cellular processes leave behind"
o The metabolome represents the collection of all metabolites in a biological cell, tissue, organ or organism, which are the end products of cellular processes
· Generational effects of nutrition
All natural ecosystems experience variability in food availability necessitating organisms to adapt to these times of shortages through phenotypic plasticity depending on the life stage involved especially during a juvenile state and can cause irreversible changes in them in adult hood or even further into the next generation.
Is the study of food nutrients and their effects on human health through epigenetic modifications. There is now considerable evidence that nutritional imbalances during gestation and lactation are linked to non-communicable diseases, such as obesity, cardiovascular disease, diabetes, hypertension, and cancer. If metabolic disturbances occur during critical time- windows of development, the resulting epigenetic alterations can lead to permanent changes in tissue and organ structure or function and predispose individuals to disease

Finally my long awaited App is available through Google Play Apps and the Apple Stores. Please ignore the screen shots as they are a disaster. If you can find the errors let me know and I will recognize you on my blog as an astute observer.

I was recently approached by a company called review.com this company does unbiased non partisan reviews on a variety of topics. The following review was done after extensive research into what constitutes a desirable dog food. http://www.reviews.com/dog-food/ and is well worth reading.

I am happy to announce that my app – SNAP: Smart Nutritional Advice for Pets – will be available in the iTunes Store and on Google Play within a week!
SNAP allows the pet guardian, nutritionist or pet store owner to keep a concise dietary and health history for the lifetime of their furry friends or clients. SNAP helps to eliminate some the guess work associated with feeding our pets by providing:
· A personalized profile for each pet – picture, birthdate, current and target body weight, current health status, activity level, vaccines, diet, etc.
· A personalized diet analysis and comparison to both the current industry minimum and the ancestral nutrient requirements for each pet based on their individual profile as well as nutritional calculations of the food and treats currently being fed.
· A comprehensive and exportable dietary and health history to share with your veterinarian.
Understanding your pet’s dietary requirements and the impact on their health will be a SNAP with detailed nutritional analysis of the daily food and treats you are currently feeding. Using a simple kitchen scale and the details of their present diet (manufacturer, product name, cost, dietary goals, etc.) you will be able to create a personalized diet analysis that can be adapted for new health goals and changes in the food you are feeding.
Feedback from the user community is welcome; I invite you to send me your comments and suggestions so they can be incorporated in to future versions of the app.
Thank you for your continued support!
