What dietary factors could contribute to folate deficiency?

A dietary factor that significantly contributes to folate deficiency is inadequate intake of fruits and vegetables. Folate, also known as vitamin B9, is abundantly found in leafy greens, legumes, fruits, and vegetables. These food groups are primary sources of folate in the diet, and a low consumption of them can lead to insufficient folate levels in the body.

Fruits and vegetables contain not only folate but also other essential vitamins and minerals that work synergistically to support overall health. When individuals do not consume enough of these foods, they miss out on these vital nutrients, which can lead to deficiencies.

In contrast, consumption of oily fish, increased intake of dairy products, and high sugar consumption do not directly impact folate levels in the same way. While various foods may contribute to overall health or contribute to other deficiencies, the direct link between folate deficiency and inadequate fruit and vegetable intake is well-documented in nutritional science.
