Grapefruit, orange, and lemon are the principal members of the citrus family. Grapefruit is a subtropical citrus tree grown for its fruit. Its origin is not clear, but it may originally have been a hybrid of the pomelo and the sweet orange tree. Tangelo is a hybrid of grapefruit and orange, and has a less bitter taste than grapefruit.
Grapefruit is pinkish- to yellow-skinned and oblate to round, ranging in diameter from 10 to 15 cm. The most popular varieties cultivated are referred to by the colour of the segmented pulp, which can be red, white, or pink. Grapefruit flavour ranges from highly acidic and somewhat bitter to sweet and tart. Unlike other citrus fruits, grapefruit contains mercaptan, a terpene partly composed of sulphur; mercaptan has a strong influence on the taste and odour of the fruit.

Elevated levels of IgG/IgA reaction to a certain food does not necessarily mean you have an intolerance, but research shows that by eliminating foods that cause an the reaction, you can potentially improve certain food-related symptoms - including gastrointestinal distress, headaches, dry and itchy skin, and fatigue. Please keep in mind that reactivity does not necessarily correlate directly with symptoms, so your results are meant to guide you through the next steps of the process.
Elimination of IgG/IgA positive foods may improve symptoms of irritable bowel syndrome, Autism Spectrum Disorders, AD(H)D, cystic fibrosis, rheumatoid arthritis, and epilepsy, according to numerous clinical studies.
IgG/IgA food test results are often used to develop food antibody-guided exclusion/ elimination diets. The implementation of such diets has been shown to alleviate symptoms associated with nonceliac gluten sensitivity and food sensitivity-induced atopic conditions, reduce the frequency of migraine headaches, decrease the occurrence of diarrhea, decrease failure-to-thrive among children with cystic fibrosis, reduce symptoms of irritable bowel syndrome, improve rectal compliance, decrease stool frequency in Crohn’s disease, prevent seizures and hyperkinetic behavior in children with epilepsy, and ameliorate kidney function in glomerulonephritis. Food elimination diets also hold promise for the improvement of behaviors associated with attention-deficit hyperactivity disorder.
