Thirty-five grams. That is roughly a quarter of a small mango. Half an orange. Two modest slices of papaya. It is the average amount of fruit consumed daily by women of reproductive age in the Arusha and Kilimanjaro regions, according to a new research brief from the CGIAR Science Program on Better Diets and Nutrition.
The brief, titled Fruit and Vegetable Intake in Arusha and Kilimanjaro, assessed dietary intake among approximately 2,600 women across the two northern Tanzania regions. The figure it produces for fruit intake is striking not just in isolation but in context. These are regions known for their agricultural richness. Kilimanjaro grows bananas at altitude. Arusha sits within reach of tomato farms, orchards, and some of the most productive market gardens in the country. And yet the women who live there are eating almost no fruit at all.
The WHO Benchmark and How Far Women Fall Short
The World Health Organization recommends a minimum of 400 grams of fruit and vegetables per day for a healthy life. The combined average intake recorded in the survey was 279 grams per day, a gap of 121 grams from the minimum. What makes the finding more striking is its near-universality: 98.8% of the approximately 2,600 women surveyed consumed less than the recommended 400 grams per day.
This is not a problem at the margins. It is a norm. The vast majority of women in two of Tanzania’s most agriculturally productive regions are failing to meet the most basic dietary standard for health.
The breakdown between fruit and vegetables tells the story more precisely. The average usual intake of vegetables was 245 grams per day, which, while still below the 400-gram combined threshold, at least reflects a meaningful presence of vegetables in the diet. Fruit, at 35 grams per day, is barely present at all.
Why Is Fruit Missing?
The brief identifies household wealth and food security as the primary predictors of fruit and vegetable intake. Women from wealthier and more food-secure households ate more of both, but the gradient for fruit was particularly steep. Fruit in Tanzania is largely a market purchase. Unlike vegetables, which can be grown in small home gardens, incorporated into stews, or obtained as part of community distributions, fruit requires cash and proximity to a reliable supplier.
The food environments research conducted in parallel, covering a census of 1,184 retail outlets across 15 markets and 108 retail outlets in the two regions, found that only 22% of vendors sold fruit. Compare this with 65% of vendors selling fried foods and snacks, and the structural explanation for the 35-gram figure becomes clear. The market is not configured to deliver fruit to consumers who need it.
There is also a cultural dimension. Vegetables have deep roots in Tanzanian cuisine: sukuma wiki, mchicha, mlenda, and other traditional greens feature regularly in the pot. Fruit, outside of banana-growing households, is often treated as a supplementary or seasonal item rather than a daily dietary component. Changing that habit requires more than access. It requires a shift in how fruit is understood as food.
The Wealth Gradient and What It Means for Policy
The research includes a chart tracking average usual intake of fruit and vegetables across five household wealth quintiles. The pattern is consistent: the poorest women eat the least, and intake rises with wealth. But even in the wealthiest quintile, fruit intake remains strikingly low, peaking at 38 grams per day in the fifth wealth quintile compared to 26 grams in the first.
This is a key finding for policymakers. The fruit intake gap is not simply a poverty problem that economic growth will resolve over time. Even among relatively well-off women in Arusha and Kilimanjaro, fruit consumption remains far below what health requires. The implication is that affordability matters, but it is not the only barrier. Availability, habit, and food environment design all play roles that will require targeted intervention.
The Research Ahead
The CGIAR team is assessing dietary patterns and their drivers and consequences to understand if, how, and when people consume fruit and vegetables. They aim to identify and test behavioural interventions to improve fruit and vegetable intake and the nutrition and health outcomes of key population groups.
The baseline they are working from is unambiguous. In a region that grows abundant food, 35 grams of fruit a day is not a dietary curiosity. It is a public health signal that something, somewhere in the system between farm and fork, is failing.
