• For example, fruit-flavored yogurt can pack more sugar than a bag of candy.

Here's what Buettner recommends in his 7-Day Longevity Reset:

• Nuts.

❌ Never buy these:

• Sugary drinks.
• Salty snacks, like chips.
• Processed meats.
• Pre-packaged sweets.

• "I love wine," he said. "I don't drink hard liquor anymore and I'll have the very occasional beer. But I'm a big fan of high-quality wines. Instead of drinking a lot of them, I drink a little bit."
