Hypothesis
How do modifiable lifestyle factors relate to vitamin C and/or β-carotene deficiency in healthy adults?
Conclusion
The study found that smoking, lack of physical activity, and low fruit consumption significantly increase the risk of vitamin C and β-carotene deficiencies.
Supporting Evidence
- Smoking was associated with a 19% decrease in vitamin C levels.
- Regular physical activity increased vitamin C levels by 9%.
- Intake of less than 2 fruits per day significantly increased the risk of vitamin C deficiency.
- Overweight was linked to a higher risk of β-carotene deficiency.
- Women using oral contraceptives had lower β-carotene levels.
Takeaway
Eating fruits, exercising, and not smoking can help keep your body healthy by making sure you have enough vitamins.
