They want to change the perfect creation of Allāh ﷻ. They destroy everything even our health. The Prophet ﷺ showed us how to be healthy and taught us the perfect diet. Look carefully for unchanged, good food. Health is a favour from Allāh ﷻ. We must look after it by following Allāh’s ﷻ orders. The best for believers is to be healthy and not a burden for others.
