The utilization of wild food is well known in many developing countries including Tanzania, but its relationship with the people's health situation has not been well-researched. This article analyzed the correlation between the intake of wild food and health situation based on answers from 253 villagers to questionnaire interviews in 3 areas of Tanzania. For health situations, the Swahili version of the global subjective evaluation SF-12 for adults was used. Correlation and multiple regression analysis with other indicators related to age, sex, food production, frequency of staple food intake, and subjective poverty/welfare status, and cross-tabulation were implemented. In a semi-arid village of Dodoma with a generally low intake of wild food, respondents with a higher intake of wild food in the rainy season had a good evaluation of General Health (GH). The utilization of leafy vegetables in the season may have positively influenced their health. In an inland village of Lindi, respondents with a high intake of wild food in both seasons had a high evaluation of Physical Function (PF). The diverse variety of wild food may have contributed to their health, but there is also a possibility that their high physical function may have allowed them to collect wild food. In a coastal village of Lindi, respondents with higher intake of wild food had poorer health: Role Emotion (RE) in the dry season; Role Physical (RP), Vitality (VT) in the rainy season. While the location of the wild food in the residential area may have influenced, various reasons need to be further investigated. The research highlighted different correlations between villages, and the positive influence of wild food intake can further be investigated for promotion in low consumption areas for health benefits.
