Hi everyone,

Sometimes foods don't live up to their nutritional hype, and this week, a new large revealed that artificial sweeteners may not be helpful weight loss aids after all. Researchers found that sugar substitutes may instead contribute to weight gain and other health problems. (Having a little every now and then probably doesn't make much difference, but most people should try to cut back on the sweet stuff altogether, experts say.)

We also explored meal kits, which are marketed as tools to help people cook more and spend less money on takeout. Though more companies are selling them, that doesn't mean more Americans are cooking.

How often do you cook—and how did you learn? We'd love to hear from you at health@time.com.

Be well,
