Some dietary foods are considered protective, such as vegetables and fruits.
However, fatty foods are thought to enhance the risk for Crohn's disease.
The evidence, however, is inconsistent.
Dr Savio D'Souza and colleagues from Canada postulated that specific dietary patterns may influence the risk for Crohn's disease.

The research team conducted a case-control study.
The team selected newly diagnosed Crohn's disease cases with population and/or hospital-based controls 20 years from 3 tertiary hospitals across Canada.
Predisease diet was assessed using a validated food frequency questionnaire administered within 1 month of diagnosis.
The team used factor analyses and unconditional logistic regression to determine gender-specific dietary patterns and assess associated risks for Crohn's disease.
Odds ratios and corresponding 95% confidence intervals were estimated.
The researchers included a total of 149 cases, and 251 controls.
The mean age of the cases was 13 years, of which 61% were males.
The team observed 4 dietary patterns each among both boys and girls.
Pattern 1 in girls, characterized by meats, fatty foods, and desserts, was positively associated with Crohn's disease.
Pattern 2, common to both boys and girls, was characterized by vegetables, fruits, olive oil, fish, grains, and nuts.
The researchers noted that pattern 2 was inversely associated with Crohn's disease in both genders.
Dr D'Souza's team concluded, "Our results suggest that specific dietary patterns could be associated with higher or lower risks for Crohn's disease in children."
"Larger prospective studies are required to confirm these findings."
