Stop Counting Calories. Start Adding Years.

Will you be there to meet your great-grandchildren?

Will you see your kids graduate? Walk your daughter down the aisle? Will you be there to meet your great-grandchildren?

These are the moments we live for—but modern habits can silently take them away.

Longist is reimagining nutrition by shifting the focus from calories to longevity.

Calories differ in quality - some add years to your life, others quietly take them away.
