Food can cause a reaction such as cutaneous, oral/gastrointestinal,respiratory symptoms, and generalized reactions, including fatal anaphylaxis (7)

Anaphylaxis

In a university in Spain, a study was conducted to analyze the intake of cocoa and students' health status. The results were grouped according to low (LC), moderate (MC), and high (HC) consumers of cocoa. Among 270 participants, 87 were cocoa intolerant. Among the groups, 28%, 13% and 19% were allergic to the LC, MC and HC group, respectively. Around 36% of these showed cutaneous reactions such as hives, redness or itching. Approximately 34% of the individuals developed symptoms like rhinitis, sneezing or mouth itching. Among these allergic patients, three of them, due to severe reaction, had to stay home for recovery(12).

Contact Urticaria

A study to investigate allergens causing acute urticaria in children was conducted in Iran. One hundred and twenty-nine children suffering from acute urticaria participated in the study. Among these, 11.6% were observed to show positive skin prick tests to cocoa. Studies have shown in some cases, following food avoidance treatment to children suffering from urticaria may cause malnutrition, developmental and behavioral disorders (13).

Gastrointestinal

A study in Mexico analyzing patients with food allergy reported 23% suffering from gastrointestinal symptoms, 38% with cutaneous rash, 15% with eczema and 17% with wheezing or cough. Among these patients, 8.3% were observed to have sensitization towards cocoa, 28% to milk, 6.6% to almonds and 5% to peanuts (14, 15).

Atopic Dermatitis

A study was done in Finland to know the prevalence of allergic reactions in 1120 atopic individuals with common spices using a scratch test. In these patients, atopic dermatitis was detected in about 50% of the patients. Around 2.2% showed positive skin tests to cocoa (16).

Allergic Rhinitis (AR) and Allergic Rhino Conjunctivitis (ARC)

A study was conducted in Turkey to know the prevalence of anamnestic food allergy in patients with seasonal allergic rhinitis. The results showed that around 1.2 percent of the patients (n =9) had an allergic reaction to cacao (17).

Asthma

A case was reported from Canada in which occupational asthma occurred due to cacao. A confectionary worker, aged 31 years, had a history of allergy (familial and personal). The worker developed symptoms such as nasal pruritus and congestion, rhinorrhoea, sneezing, shortness of breath, coughing and wheezing after coming in contact with cacao beans. The study stated these symptoms seemed to improve after removing his connection with the cacao beans during his work (11). In another study in confectionery workers, the prevalence of asthma was 26.1% percent in workers with positive skin prick tests. These positive results occurred with cacao, chocolate and cocoa extracts to 31%, 9%, and 6% of the workers, respectively (8).
