Bay Area Soda Taxes Don’t Just Affect Sales: They Help Change People’s Minds

It wasn’t that long ago when cigarettes and soda were go-to convenience store vices, glamorized in movies and marketed toward, well, everyone.

Then, lawmakers and voters raised taxes on cigarettes, and millions of dollars went into public education campaigns about smoking’s harms. Decades of news coverage chronicled how addictive and dangerous cigarettes were and the enormous steps companies took to hide the risks and hook more users.

The result: a radical shift in social norms that made it less acceptable to smoke and pushed cigarette use to historic lows, especially among minors.

New UC Berkeley research suggests sugar-sweetened beverages may be on a similar path.

The city of Berkeley’s first-in-the-nation soda tax a decade ago, along with more recent Bay Area tax increases on sugar-sweetened drinks, have not only led to reduced sales. They are also associated with significant changes in social norms and attitudes about the healthfulness of sweet drinks, said Kristine A. Madsen, a professor at UC Berkeley’s School of Public Health and senior author of a paper published Nov. 25 in the journal BMC Public Health.

Over the span of just a few years, taxes coupled with significant media attention significantly affected the public’s overall perceptions of sugar-sweetened beverages, which include sodas, some juices, and sports drinks. Such a shift in the informal rules surrounding how people think and act could have major implications for public health efforts more broadly, Madsen said.

“Social norms are really powerful. The significant shift we saw in how people are thinking about sugary drinks demonstrates what else we could do,” Madsen said. “We could reimagine a healthier food system. It starts with people thinking, ‘Why drink so much soda?’ But what if we also said, ‘Why isn’t most of the food in our grocery stores food that makes us healthy?’”

Madsen and colleagues from UC San Francisco and UC Davis analyzed surveys from 9,128 people living in lower-income neighborhoods in Berkeley, Oakland, San Francisco, and Richmond. Using data from 2016 to 2019 and 2021, they studied year-to-year trends in people’s perception of sugar-sweetened beverages.

They wanted to understand how the four taxes in the Bay Area might have affected social norms surrounding sugary beverages — the unwritten and often unspoken rules that influence the food and drinks we buy, the clothes we wear and our habits at the dinner table.

Although social norms aren’t visible, they are incredibly powerful forces on our actions and behaviors; just ask anyone who has bought something after an influencer promoted it on TikTok or Instagram.

Researchers asked questions about how often people thought their neighbors drank sodas, sports drinks, and fruity beverages. Participants also rated how healthy several drinks were, which conveyed their own attitudes about the beverages.

The researchers found a 28% decline in the social acceptability of drinking sugar-sweetened beverages.

In Oakland, positive perceptions of peers’ consumption of sports drinks declined after the tax increase, relative to other cities. Similarly, in San Francisco, attitudes about the healthfulness of sugar-sweetened fruit drinks also declined.

In other words, people believed their neighbors weren’t drinking as many sugar-sweetened beverages, which affected their own interest in consuming soda, juices, and sports drinks.

“What it means when social norms change is that people say, ‘Gosh, I guess we don’t drink soda. That’s just not what we do. Not as much. Not all the time,’” Madsen said. “And that’s an amazing shift in mindsets.”

The research is the latest from UC Berkeley that examines how consumption patterns have changed in the decade since Berkeley implemented the nation’s first soda tax.

A 2016 study found a decrease in soda consumption and an increase in people turning to water. Research in 2019 documented a sharp decline in people turning to sugar-sweetened drinks. And earlier this year, Berkeley researchers documented that sugar-sweetened beverage purchases declined dramatically and steadily across five major American cities after taxes were put in place.

The penny-per-ounce tax on beverages, which is levied on distributors of sugary drinks — who ultimately pass that cost of doing business on to consumers — is an important means of communicating about health with the public, Madsen said.

Researchers tallied more than 700 media stories about the taxes on sugar-sweetened beverages during the study period. That level of messaging was likely a major force in driving public awareness and norms.

It’s also something Madsen said future public health interventions must consider. It was part of the progress made in cutting cigarette smoking and seems to be working with sugary drinks. And it’s those interventions that can lead to individual action.

“If we change our behaviors, the environment follows,” Madsen said. “While policy really matters and is incredibly important, we as individuals have to advocate for a healthier food system.”

Lu Lu’s House is Not Just Toying Around with the Community

Wilson and Lambert will be partnering with Mayor Barbara Lee on a toy giveaway on Dec. 20. Young people, like Dremont Wilkes, age 15, will help give away toys and encourage young people to stay in school and out of trouble. Wilkes wants to go to college and become a specialist in financial aid. Sports agent Aaron Goodwin has committed to giving all eight young people from Lu Lu’s House a fully paid free ride to college, provided they keep a 3.0 grade point average and continue the program. Lu Lu’s House is not toying around.

Lu Lu’s House is a 501c3 organization based in Oakland, founded by Mr. Zirl Wilson and Mr. Tracy Lambert, both previously incarcerated. After their release from jail, they wanted to change things for the better in the community — and wow, have they done that!

The duo developed housing for previously incarcerated people, calling it “Lu Lu’s House,” after Wilson’s wonderful wife. At a time when many young people were robbing, looting, and involved in shootings, Wilson and Lambert took it upon themselves to risk their lives to engage young gang members and teach them about nonviolence, safety, cleanliness, business, education, and the importance of health and longevity.

Lambert sold hats and T-shirts at the Eastmont Mall and was visited by his friend Wilson. At the mall, they witnessed gangs of young people running into the stores, stealing whatever they could get their hands on and then rushing out. Wilson tried to stop them after numerous robberies and finally called the police, who Wilson said, “did not respond.” Having been incarcerated previously, they realized that if the young people were allowed to continue to rob the stores, they could receive multiple criminal counts, which would take their case from misdemeanors to felonies, resulting in incarceration.

Wilson took it upon himself to follow the young people home and when he arrived at their subsidized homes, he realized the importance of trying to save the young people from violence, drug addiction, lack of self-worth, and incarceration — as well as their families from losing subsidized housing. Lambert and Wilson explained to the young men and women, ages 13-17, that there were positive options which might allow them to make money legally and stay out of jail. Wilson and Lambert decided to teach them how to wash cars and they opened a car wash in East Oakland. Oakland’s Initiative, “Keep the town clean,” involved the young people from Lu Lu’s House participating in more than eight cleanup sessions throughout Oakland. To assist with their infrastructure, Lu Lu’s House has partnered with Oakland’s Private Industry Council.

For the Christmas season, Lu Lu’s House and reformed young people (who were previously robbed) will continue to give back.

Desmond Gumbs — Visionary Founder, Mentor, and Builder of Opportunity

Gumbs’ coaching and leadership journey spans from Bishop O’Dowd High School, Oakland High School, Stellar Prep High School. Over the decades, hundreds of his students have gone on to college, earning academic and athletic scholarships and developing life skills that extend well beyond sports.

Special to the Post

For more than 25 years, Desmond Gumbs has been a cornerstone of Bay Area education and athletics — not simply as a coach, but as a mentor, founder, and architect of opportunity. While recent media narratives have focused narrowly on challenges, they fail to capture the far more important truth: Gumbs’ life’s work has been dedicated to building pathways to college, character, and long-term success for hundreds of young people.

A Career Defined by Impact

One of his most enduring contributions is his role as founder of Stellar Prep High School, a non-traditional, mission-driven institution created to serve students who needed additional structure, belief, and opportunity. Through Stellar Prep numerous students have advanced to college — many with scholarships — demonstrating Gumbs’ deep commitment to education as the foundation for athletic and personal success.

A Personal Testament to the Mission: Addison Gumbs

Perhaps no example better reflects Desmond Gumbs’ philosophy than the journey of his son, Addison Gumbs. Addison became an Army All-American, one of the highest honors in high school football — and notably, the last Army All-Americans produced by the Bay Area, alongside Najee Harris.

Both young men went on to compete at the highest levels of college football — Addison Gumbs at the University of Oklahoma, and Najee Harris at the University of Alabama — representing the Bay Area on a national level.

Building Lincoln University Athletics From the Ground Up

In 2021, Gumbs accepted one of the most difficult challenges in college athletics: launching an entire athletics department at Lincoln University in Oakland from scratch. With no established infrastructure, limited facilities, and eventually the loss of key financial aid resources, he nonetheless built opportunities where none existed.

Under his leadership, Lincoln University introduced:

Football
Men’s and Women’s Basketball
Men’s and Women’s Soccer

Operating as an independent program with no capital and no conference safety net, Gumbs was forced to innovate — finding ways to sustain teams, schedule competition, and keep student-athletes enrolled and progressing toward degrees. The work was never about comfort; it was about access.

Voices That Reflect His Impact

Desmond Gumbs’ philosophy has been consistently reflected in his own published words:

“if you have an idea, you’re 75% there the remaining 25% is actually doing it.”
“This generation doesn’t respect the title — they respect the person.”
“Greatness is a habit, not a moment.”

Former players and community members have echoed similar sentiments in public commentary, crediting Gumbs with teaching them leadership, accountability, confidence, and belief in themselves — lessons that outlast any single season.

Context Matters More Than Headlines

Recent articles critical of Lincoln University athletics focus on logistical and financial hardships while ignoring the reality of building a new program with limited resources in one of the most expensive regions in the country. Such narratives are ultimately harmful and incomplete, failing to recognize the courage it takes to create opportunity instead of walking away when conditions are difficult.

The real story is not about early struggles — it is about vision, resilience, and service.

A Legacy That Endures

From founding Stellar PREP High School, to sending hundreds of students to college, to producing elite athletes like Addison Gumbs, to launching Lincoln University athletics, Desmond Gumbs’ legacy is one of belief in young people and relentless commitment to opportunity.

His work cannot be reduced to headlines or records. It lives on in degrees earned, scholarships secured, leaders developed, and futures changed — across the Bay Area and beyond.
