In a world fairly saturated with diet trends, superfood fads, and contradictory nutritional recommendations, the idea of healthy eating can feel confusing and exhausting. One week, carbs are the enemy; the next week, fat is back in fashion. Against this backdrop of confusion and trend-chasing, the wisdom of life can be easily overlooked. And that is why the voice of Marion Nestle matters now more than ever.

Nestle’s attitude toward healthy eating couldn’t possibly offer a more timely reminder that healthy eating doesn’t necessarily have to involve expensive and tedious processes and recipes.
