University of Florida researchers are calling for a national transformation in how we address the ongoing epidemic of obesity and Type 2 diabetes, starting with a fundamental shift in how we approach health, agriculture and food.


Published recently in the Proceedings of the National Academy of Sciences, the article argues that fruits and vegetables must be treated not just as food — but as medicine. 


With 73% of U.S. adults and 35% of children classified as overweight or obese, the authors warn that the crisis is not only an individual health issue but a national economic and security threat. 


Andrew Hanson, Ph.D., a co-author and professor of horticultural sciences at UF/IFAS, emphasized a sense of urgency and collective responsibility toward solving this health crisis. 


“This isn’t business as usual. We’re taking a public-interest view. This is the kind of thing we all need to be talking about. It’s too important not to,” he said. 


The article proposes a roadmap for change, including creating five National Institutes of Health-supported “Food Is Medicine” centers across the U.S., with Florida as a leading candidate; scaling up domestic fruit and vegetable production to meet national dietary needs; partnering with food producer and processors to make healthy foods more accessible, affordable and appealing; and reforming medical and nutrition education to include horticultural sciences and vice versa.



The article highlights that only 1 in 10 adults meets the recommended daily intake of fruits and vegetables, and that U.S. production falls far short of what’s needed to support a healthy population. The authors call for a dramatic expansion of fruit and vegetable production, especially high-impact crops like berries, leafy greens and carrots. 


Christopher Gunter, Ph.D., professor and chair of the UF/IFAS Department of Horticultural Sciences, said the team’s goal is to push the role fruit and vegetables crops can play in improving human health into the national consciousness.


“As a discipline, horticulture and the science of fruit and vegetables have been largely ignored in this conversation,” Gunter said. “Our goal is to move the needle on health with fruit and vegetables.”  


Hanson said about 80% of the nation’s cropland is used to grow soybeans, corn and wheat — most of which are processed into products with low nutritional value that contribute to the obesity and Type 2 diabetes epidemic. 


Mike Jaffee, M.D., a co-author and professor of neurology in the UF College of Medicine, stressed the broader implications of a high-vegetable diet on brain health. 


“Obesity and insulin resistance are linked to inflammation and neurodegeneration. We’re living longer, but our brains aren’t keeping up. That’s where the real cost to individuals and the health care system comes in,” he said. 


Gunter agreed, adding, “This epidemic reduces the longevity and productivity of our citizens. It limits the momentum communities need to grow healthy and resilient families.” 


Hanson pointed out that higher socioeconomic groups are better positioned to meet dietary recommendations, making this not just a health issue, but a deeply embedded social and economic one. 


“This crisis takes an unduly large toll on people with lower incomes and less time. To eat enough fruits and vegetables in the current system, you need substantial income and time to prepare food. That’s a luxury many don’t have,” he said. 


The authors argue that farmers bring essential knowledge to the table.  


“They understand how environmental factors impact nutritional quality,” Gunter said.

AI in the classroom: What parents need to know

As students return to classrooms, Maya Israel, professor of educational technology and computer science education at the University of Florida, shares insights on best practices for AI use for students in K-12. She also serves as the director of CSEveryone Center for Computer Science Education at UF, a program created to boost teachers’ capabilities around computer science and AI in education. Israel also leads the Florida K-12 Education Task Force, a group committed to empowering educators, students, families and administrators by harnessing the transformative potential of AI in K-12 classrooms, prioritizing safety, privacy, access and fairness. How are K–12 students using AI in classrooms? There is a wide range of approaches that students are using AI in classrooms. It depends on several factors including district policies, student age and the teacher’s instructional goals. Some districts restrict AI to only teacher use, such as creating custom reading passages for younger students. Others allow older students to use tools to check grammar, create visuals or run science simulations. Even then, skilled teachers frame AI as one tool, not a replacement for student thinking and effort. What are examples of age-appropriate tools that enhance learning? AI tools can be used to either enhance or erode learner agency and critical thinking. It is up to the educators to consider how these tools can be used appropriately. It is critical to use AI tools in a manner that supports learning, creativity and problem solving rather than bypass critical thinking. For example, Canva lets students create infographics, posters and videos to show understanding. Google’s Teachable Machine helps students learn AI concepts by training their own image-recognition models. These types of AI-augmented tools work best when they are embedded into activities such as project-based learning, where AI supports learning and critical thinking. How do teachers ensure AI supports core skills? While AI can be incredibly helpful in supporting learning, it should not be a shortcut that allows students to bypass learning. Teachers should design learning opportunities that integrate AI in a manner that encourages critical thinking. For example, if students are using AI to support their mathematical understanding, teachers should ask them to explain their reasoning, engage in discussions and attempt to solve problems in different ways. Teachers can ask students questions like, “Does that answer make sense based on what you know?” or “Why do you think [said AI tool] made that suggestion?” This type of reflection reinforces the message that learning does not happen through getting fast answers. Learning happens through exploration, productive struggle and collaboration. Many parents worry that using AI might make students too dependent on technology. How do educators address that concern? This is a very valid concern. Over-reliance on AI can erode independence and critical thinking, that’s why teachers should be intentional in how they use AI for teaching and learning. Educators can address this concern by communicating with parents their policies and approaches to using AI with students. This approach can include providing clear expectations of when AI is used, designing assignments that require critical thinking, personal reflection and reasoning and teaching students the metacognitive skills to self-assess how and when to use AI so that it is used to support learning rather than as a crutch. How do schools ensure that students still develop original thinking and creativity when using AI for assignments or projects? In the age of AI, there is the need to be even more intentional designing learning experiences where students engage in creative and critical thinking. One of the best practices that have shown to support this is the use of project-based learning, where students must create, iterate and evaluate ideas based on feedback from their peers and teachers. AI can help students gather ideas or organize research, but the students must ask the questions, synthesize information and produce original ideas. Assessment and rubrics should emphasize skills such as reasoning, process and creativity rather than just focusing on the final product. That way, although AI can play a role in instruction, the goal is to design instructional activities that move beyond what the AI can do. How do educators help students understand when it’s appropriate to use AI in their schoolwork? In the age of AI, educators should help students develop the skills to be original thinkers who can use AI thoughtfully and responsibly. Educators can help students understand when to use AI in their school work by directly embedding AI literacy into their instruction. AI literacy includes having discussions about the capabilities and limitations of AI, ethical considerations and the importance of students’ agency and original thoughts. Additionally, clear guidelines and policies help students navigate some of the gray areas of AI usage. What guidance should parents give at home? There are several key messages that parents should give their children about the use of AI. The most important message is that even though AI is powerful, it does not replace their judgement, creativity or empathy. Even though AI can provide fast answers, it is important for students to learn the skills themselves. Another key message is to know the rules about AI in the classroom. Parents should speak with their students about the mental health implications of over-reliance on AI. When students turn to AI-augmented tools for every answer or idea, they can gradually lose confidence in their own problem-solving abilities. Instead, students should learn how to use AI in ways that strengthen their skills and build independence.

Is writing with AI at work undermining your credibility?

With over 75% of professionals using AI in their daily work, writing and editing messages with tools like ChatGPT, Gemini, Copilot or Claude has become a commonplace practice. While generative AI tools are seen to make writing easier, are they effective for communicating between managers and employees? A new study of 1,100 professionals reveals a critical paradox in workplace communications: AI tools can make managers’ emails more professional, but regular use can undermine trust between them and their employees. “We see a tension between perceptions of message quality and perceptions of the sender,” said Anthony Coman, Ph.D., a researcher at the University of Florida's Warrington College of Business and study co-author. “Despite positive impressions of professionalism in AI-assisted writing, managers who use AI for routine communication tasks put their trustworthiness at risk when using medium- to high-levels of AI assistance." In the study published in the International Journal of Business Communication, Coman and his co-author, Peter Cardon, Ph.D., of the University of Southern California, surveyed professionals about how they viewed emails that they were told were written with low, medium and high AI assistance. Survey participants were asked to evaluate different AI-written versions of a congratulatory message on both their perception of the message content and their perception of the sender. While AI-assisted writing was generally seen as efficient, effective, and professional, Coman and Cardon found a “perception gap” in messages that were written by managers versus those written by employees. “When people evaluate their own use of AI, they tend to rate their use similarly across low, medium and high levels of assistance,” Coman explained. “However, when rating other’s use, magnitude becomes important. Overall, professionals view their own AI use leniently, yet they are more skeptical of the same levels of assistance when used by supervisors.” While low levels of AI help, like grammar or editing, were generally acceptable, higher levels of assistance triggered negative perceptions. The perception gap is especially significant when employees perceive higher levels of AI writing, bringing into question the authorship, integrity, caring and competency of their manager. The impact on trust was substantial: Only 40% to 52% of employees viewed supervisors as sincere when they used high levels of AI, compared to 83% for low-assistance messages. Similarly, while 95% found low-AI supervisor messages professional, this dropped to 69-73% when supervisors relied heavily on AI tools. The findings reveal employees can often detect AI-generated content and interpret its use as laziness or lack of caring. When supervisors rely heavily on AI for messages like team congratulations or motivational communications, employees perceive them as less sincere and question their leadership abilities. “In some cases, AI-assisted writing can undermine perceptions of traits linked to a supervisor’s trustworthiness,” Coman noted, specifically citing impacts on perceived ability and integrity, both key components of cognitive-based trust. The study suggests managers should carefully consider message type, level of AI assistance and relational context before using AI in their writing. While AI may be appropriate and professionally received for informational or routine communications, like meeting reminders or factual announcements, relationship-oriented messages requiring empathy, praise, congratulations, motivation or personal feedback are better handled with minimal technological intervention.

MedPage Today: Ozzy Osbourne shined a light on Parkinson’s stigma

Ozzy Osbourne was best known for two things: his shape-shifting resilience as a pioneer of heavy metal music and, most recently, his remarkable authenticity during his public journey with Parkinson's disease. Osbourne, who passed away on July 22, possessed a unique ability to connect directly with people who were suffering. He was an honest and transparent voice for what it was like to live with a neurodegenerative disease. He was willing to go where others would not, and he took on the stigma of a Parkinson's diagnosis. Stigma remains one of the most underrecognized yet pervasive challenges in Parkinson's disease. Far too often, individuals are made to feel ashamed of their visible symptoms like tremors, facial masking, or soft speech. This reality can lead to social withdrawal, depression, and even delayed medical care. Research has shown that perceived stigma is not only linked to reduced quality of life, but it also correlates with worse outcomes. That's why, when someone like Osbourne rises up and speaks out, it matters. It sends a powerful message that Parkinson's does not define a person, and that no one should suffer in silence. Many people with Parkinson's disease choose to conceal their diagnosis from those closest to them. A recent study published in Scientific Reports found that nearly 23% of participants kept their condition hidden, even from family members. Broader surveys have suggested that more than half of individuals with Parkinson's disease may conceal symptoms, mask tremors, or avoid public situations due to stigma and fear of judgment. People who hide their diagnosis frequently report lower social support, reduced engagement in physical activity, and significantly worse emotional well-being. These findings underscore how pervasive and harmful disclosure avoidance can be.
