I appreciate that there's a difference in marketing, and McDs isn't actively suggesting you should eat there everyday (unlike Soylent), but take a look at this page: http://www.mcdonalds.com/us/en/food/food_quality/nutrition_choices/balancing_busy_lives/a_balancing_act.html http://www.mcdonalds.com/us/en/food/food_quality/nutrition_c... There's no mention of food from other places, and the final paragraph ("Variety keeps things interesting") certainly implies you could eat there daily without problem, to the exclusion of other food sources.
