As there was shortage of data on the prevalence of lactose intolerance and nutritional status, this study aimed to determine this relation and its effects on food habits of the study sample. Data was collected from students of five faculties in Khartoum University. A total of 140 students (70 of them were selected according to the symptoms they suffer from after drinking milk (experimental group) and the same number was selected because they drink milk without any complaints (controls). Data collection was completed at the five Faculties using questionnaires (Socio-demographics, symptoms and food habits), anthropometric measurements and Laboratory investigations. The age of the studied sample ranged between 18 and 24 years. The majority of the studied sample was females (78%). No significant differences were found between the two sexes. Lactose intolerance was found to be significantly higher among the older age group (P <0.021). The study reviled that the nutritional status of the sample studied was found to be below average, as indicated by their anthropometrics. The majority of average heights and weights of females and males were between the 25th and 50th percentiles except for males whose heights were even worse. Most of them were between 15th and 25th percentiles compared to US reference population (NCHS, 1994). Nausea was the highest complaint felt after consuming milk, only 72.9% of the student who were milk intolerant was found to be maldigester. (Blood glucose below 20 mg /100 ml), and 27.1% were digesters. Among the studied sample, it was found that yogurt and cheese intake of lactose intolerant students was significantly higher than among lactose tolerant students (P>0.05). Subjects’ food Intake during the last 24 hours was categorized into food groups and it was found that vegetables were not taken by a high percentage of students (25%) among both lactose tolerant and intolerants and there were no significant differences between them. Fruits intake was found to be significantly higher among lactose intolerants (P>0.05); nevertheless, the number of students who took fruits was very low from the two groups (22.1% and 12.9% respectively). Nutrition education programs targeting university students encouraging more consumption of vegetables and fruits are very important. Lactose intolerants students should learn that the consumption of small amount of milk with solid foods could mitigate symptoms in many intolerant individuals. They can also easily tolerate yogurt and cheese
