Design outcomes

Primary

Measure	Time frame
Change in Serum Vitamin D Levels:The change in serum 25-hydroxy vitamin D concentration between the beginning of the study and the end of the intervention period.This is the primary indicator of vitamin D status in the body and directly reflects the effect of the intervention. Timepoint: Four months. Method of measurement: In this study, the effect of consuming tomato paste enriched with vitamin D3 on the serum levels of 100 volunteers aged 20 to 60 years with appropriate eligibility criteria such as not having severe vitamin D deficiency and people with a BMI less than 30 will be investigated. These people will consume the product for 4 months. It is possible to obtain 800 to 1000 units of vitamin D through foods fortified with this vitamin. In order to obtain this amount of vitamin and in accordance with the amount of vitamin D added to the product, it is considered to consume 100 grams of tomato paste per day. Finally, changes in serum vitamin D levels in people will be determined using a blood test.	—
