You’re right that dietary changes can impact health, but there are other factors at play. Stress from moving to a new country or experiencing forced dislocation can have serious effects on physical health, weakening the immune system and disrupting overall well-being. Along with this, shifting away from nature-based vocations to more sedentary lifestyles contributes to health decline. The increased consumption of sugar and alcohol also exacerbates dental and general health issues. So, it’s not just diet but a combination of stress, lifestyle changes, and modern substances that contribute to health problems in these populations.
