Textos Básicos em Nutrição Pet
A hipersensibilidade alimentar é um tipo de reação adversa de origem imunológica não sazonal e pruriginosa associada à ingestão de alguma substância (material antigênico) encontrada no alimento do cão (Scott et al, 2001) ou do gato. A base imunológica da alergia alimentar em cães e gatos não é bem caracterizada. Em humanos, a hipersensibilidade do tipo I é relatada com mais freqüência, porém, as hipersensibilidades dos tipos III e IV também estão envolvidas (Ihrke, 2009). Os sinais clínicos são cutâneos e normalmente incluem prurido e eritema, podendo afetar qualquer parte do corpo do animal sendo que a face, as orelhas, as extremidades e a região ventral são os locais mais acometidos. Freqüentemente, observa-se otite externa e, em casos graves, otite média. Pioderma secundário, dermatite piotraumática, sobrecrescimento bacteriano e sinais relacionados com prurido crônico como perda de pelos, hiperpigmentação, liquenificação, escoriação e ulceração também podem ocorrer (Loefler et al, 2004). Podem ocorrer sinais gastrintestinais juntamente com sinais dermatológicos.

From the functional point of view, water is essential for life. Older studies in dogs have demonstrated a high ability of the animals to survive without ingesting energy nutrients, and can spend more than 20 weeks without ingesting these nutrients. However, plants and animals die quickly when subjected to severe water restriction. Chemically the water is the combination of the elements hydrogen and oxygen, connected in the proportion of 2: 1, respectively (H2O), considered the most important nutrient, having the following functions:
- required for chemical reactions involving hydrolysis, eg enzymatic digestion;
- helps regulate body temperature;
- Helps to shape and elasticity to the body. As a major constituent of body fluids, water lubricates joints and eyes, protects the central nervous system and thoracic and abdominal viscera from impact, assists gas exchange, among others;
- Vehicle for the elimination of undesirable substances from the body

Additives are substances intentionally incorporated into the food for the purpose of conferring some desirable characteristic such as color, aroma, texture, stability or resistance to decomposition, as long as it does not impair its nutritional value. Since 1920, legally sanctioned additives have been frequently used in food for humans and animals. Dog and cat food manufacturers use a variety of additives to produce products that are visually attractive, have prolonged nutritional quality, have high palatability, and have a longer life.
The additives present in dog and cat food are the same or very similar to those used for food for human consumption. In general, they provide three benefits to the food: 1. organoleptic, conferring structure, texture and color; 2. Technological, acting as binders and gelling agents and 3. Nutritional, acting as vitamins and antioxidants. Those commonly used in human or animal foods include colorants, flavor enhancers, emulsifying agents, gelling substances, stabilizers, thickeners and process co-adjuvants.
Due to the fact that most commercial dog and cat foods are characterized as complete and balanced, nutrient enrichment with vitamins and minerals is the most important and beneficial use of certain food additives. Most of the ingredients with chemical, non-familiar names that appear on the packaging labels of industrialized foods are actually nutrients.
As the technology used in food processing and additives are difficult and confusing subjects, additives can generate the wrong theories by misinformed people. In addition, the theme is not always correctly put; consumer associations and some people considered specialists usually make the additives responsible for causing all kinds of animal disorders. In some circumstances, advertising abuses the negative image of synthetic additives to promote "natural" or "additive free" products. Even because the evidence linking a particular food or food component to a particular disease may be circumstantial and its consistency should be evaluated with caution.
Customers looking for additive-free products should first identify which additive they wish to avoid. Some commercial products do not contain artificial colors or flavors or synthetic preservatives. Once the customer's specific concern is indicated and considered, it may be possible to locate an acceptable full and balanced commercial product.
