Food hypersensitivity refers to all types of overreactions that an organism can have against a food component. Food sensitivity includes food allergy and food intolerance.
Food allergy is a specific form of food hypersensitivity that activates the immune system, leading to an exaggerated response. An immunological reaction is a reaction against foreign substances entering the body. An allergen (nearly always a protein in the offending food) sets off a chain of reactions in the immune system including the release of antibodies.
Over the last few decades the prevalence of studies about probiotics strains has dramatically grown in most regions of the world. Probiotics are specific strains of microorganisms, which when served to human or animals in proper amount, have a beneficial effect, improving health or reducing risk of getting sick and the probiotics are used in production of functional foods and pharmaceutical products.
This account of human nutrition describes the basic facts in a clear and simple way
without the use of complicated details or much specialist language. In the few
places where more than this is necessary, elementary explanations are given. I
believe that any averagely intelligent person will readily gain a good knowledge of
human nutrition from this book, which will also be of value to students, teachers,
nurses, doctors and health professionals.
Celiac disease has many names, such as gluten intolerance,
gluten-sensitive enteropathy, and non-tropical sprue. Each
name depicts a life-long autoimmune disorder in which a
person’s body cannot tolerate a group of grain proteins known
as gluten. These grains consist of wheat, rye, barley, and any
derivatives of these grains. Oats were always part if this list, but
recent studies have shown that a moderate consumption of oats
is safe for healthy children and adults who are well-established
on a gluten-free diet....
Acne is a disorder of the body’s pilosebaceous units.
Each unit consists of a sebaceous gland and a
canal or follicle, which is lined with cells called
keratinocytes and which contains a fine hair. Most
numerous in the skin of the face, upper back, and
chest, sebaceous glands manufacture an oily substance
called sebum, which is released onto the skin’s surface
through the follicle’s opening, or pore.
All the constituents of the narrow follicle—the hair,
sebum, and keratinocytes—may form a plug that
prevents the sebum from reaching the surface of the
skin through the pore.
