Diabetes and cardiovascular diseases have gradually become one of the world's top ten fatal causes of death for the past few years. As far as the diet is concerned, it is easy to find out how to eat healthily and which food is good for people on the Internet. The diet behavior is highly personalized and also associated with the culture and religion. In this paper, the property of fuzzy ontology is proposed. Moreover, the food ontology and type-2 fuzzy dietary ontology are further applied to the dietary assessment. Additionally, with the technologies of the type-2 fuzzy sets and fuzzy inference approach, the dietary healthy level is obtained to give users a reference for their eating. Experimental results show that the proposed approach is feasible to evaluate the dietary healthy level for the collected meal records.
