New study suggests zero-calorie sweeteners aren’t so sweet

Artificial sweeteners are the reason your soda can taste sweet without the sugar (or the guilt).

But that swap might not be as harmless as it sounds.

A new study on mice suggests artificial sweeteners could have serious long-term effects on the gut microbiome and gene activity, with the potential to stick around across multiple generations—even if offspring don’t consume sweeteners.

Of mice and sweeteners

The scientists in the study began by splitting mice into three groups, each of which received either plain water, sucralose, or stevia at doses similar to what humans consume.

  • They then bred them for two generations, with all future mice drinking only plain water.
  • The researchers tracked things like blood sugar, gut bacteria, and gene activity across each generation.

What they found: Both sweeteners changed gene activity tied to metabolism and inflammation, with mice exposed to them also showing shifts in their gut microbiome, a key player in digestion and overall health.

But sucralose stood out even compared to stevia, with its effects sticking around longer and showing up even in generations of mice who were never directly exposed.

The results suggest artificial sweeteners—especially sucralose products—may trigger changes that affect how the body processes sugar over time, which can last beyond a single lifetime, researchers say.

There is a catch: This study shows a link, not proof of cause and effect, and was also only done in mice. The researchers say further investigation is needed to determine the exact effects of artificial sweeteners in humans.

Big picture: Artificial sweeteners and additives aren’t just in diet soda or coffee; they show up in ~60% of packaged foods across the US. This includes everyday items like bread, ketchup, cereals, and snack foods, often replacing or supplementing real sugar to reduce calories.

When PFAS show up in water, it's always over the safe limit

New EPA data analyzed 4,610 water systems nationwide. The finding: 100% of locations with detectable forever chemicals (PFAS) exceeded safe limits. Some tested 59 times higher than acceptable levels.

PFAS accumulates in your body over years, raising risks of cancer, thyroid issues, and immune problems. You can't see it, taste it, or smell it—the only way to know is to test.

KETOS analyzes your water for PFAS and 30+ contaminants with lab-certified accuracy. Collect a 5-minute sample at home, mail it back (prepaid shipping included), and get results in 5 business days.

Gen Z is investing earlier than ever

Americans in their teens and 20s are increasingly ditching the avocado toast beloved by previous generations, and putting their money to work in the stock market.

By the numbers

The share of Americans aged 25-39 who make annual transfers to investment accounts more than tripled between 2013 and 2023 to reach 14.4%, outpacing increases among older Americans, per data from JPMorgan Chase Institute.

  • Meanwhile, the share of 26-year-olds who moved money into investment accounts after age 22 rose from 8% to 40% between 2015 and 2025 (excluding 401(k)s).
  • And a World Economic Forum survey shows ~30% of Gen Z say they started investing before entering the workforce, compared to just 6% of Baby Boomers.

Young folks are also taking bigger swings. Crypto and alternative assets play an outsized role in this age group, with 71% of Gen Z investors holding more than a third of their portfolio in crypto.

Analysts say younger Americans consistently report feeling less confidence in traditional career paths and financial safety nets, pushing them toward higher-risk, higher-upside bets outside of a normal 9-to-5.

Housing also plays a major role. Many Gen Zers have found themselves priced out of homeownership early in their adult lives, with the share of homebuyers in America who are aged 18-39 falling from 51% in 1999 to 44% as of last year.

As a result, more younger Americans find themselves investing money that otherwise would have gone towards a down payment or mortgage.
