The rise of veganism: What's fueling the global surge in plant based diets?
Health, Environment, and Ethics in Alignment
A major catalyst behind the growth of plant based diets is growing awareness of the triple benefits they offer—improved health, reduced climate impact, and animal welfare. Research strongly supports the health advantages of well planned vegan diets for reducing risks of heart disease, type 2 diabetes, certain cancers, and obesity. In fact, a position paper released in early 2025 affirmed that vegetarian and vegan dietary patterns are nutritionally adequate and linked to better cardiometabolic health outcomes.
Simultaneously, environmental concerns are a powerful motivator. Animal agriculture is responsible for a significant share of greenhouse gas emissions—estimates range from 15–30% globally—with plant based eating able to cut food system emissions by up to 75% and slash land and water use dramatically. Landmark modelling even suggests that universal adoption of vegan diets could free up three quarters of all agricultural land—equivalent to massive tracts now used for livestock farming.
Ethical motivations also loom large. Surveys show around 79% of self identified vegans point to animal rights and cruelty concerns as a key driver—even more so than health or climate concerns.
Food Innovation and Consumer Access
The food industry has responded in kind. Driven by consumer demand and innovation, plant based sales have skyrocketed. The U.S. vegan food market nearly doubled from $3.9 billion in 2017 to $8.1 billion in 2023, and global plant based retail sales climbed from $21.6 billion in 2019 to $29 billion in 2023. Projections foresee the vegan food market reaching $37.5 billion by 2030, with strong growth in both North America and Asia Pacific.
Restaurants and mainstream retailers now tagged vegan options clearly, while products like plant based meats and dairy are better tasting and more widely available than ever. Veganuary, the annual 'try vegan in January' campaign, exploded from just 3,300 participants in 2014 to over 25.8 million in January 2025 alone—a signifier of growing mainstream interest.
Culture, Generational Shifts and Social Influence
Younger generations are particularly pivotal. Surveys in 2025 show that more than two thirds of consumers report wanting more plant based meals—but only about one in five have made that a regular habit, pointing to a clear 'intention gap' that younger groups are closing faster. Gen Z and millennials are especially driving adoption: in the UK, nearly half of UK Gen Z intend to try meat free diets in 2025.
Social media, celebrity endorsements, documentaries, and ethical influencers have also normalized plant based lifestyles. Campaigns such as Veganuary, documentary films, and visible celebrity and athlete advocates have helped reset perceptions—making veganism feel more aspirational and accessible.
But It's Not Without Challenges
The rise isn't without friction. Economic pressures like the high cost of living and inflation have dampened growth in some markets, leading to declines in substitute meat sales and even closures of some vegan restaurants. Meanwhile, backlash from dietary counter culture movements (e.g. the 'carnivore diet') and skepticism about ultra processed vegan foods also represent competing cultural forces
What's Next?
Looking ahead, growth is expected to continue, though increasingly via 'flexitarian' rather than exclusively vegan consumers—people reducing but not eliminating animal products. With pro plant based dietary policies, government backing, corporate innovation, and shifting cultural norms, plant based diets are poised to remain a major global trend.
Ultimately, the surge is fueled not by any single factor but by the alignment of ethics, health, activism, industry, and awareness—a convergence that's shifting how millions around the world think about the food they eat and the impact it has.

How the pursuit of perfection is making teenagers angsty
Teena seems to be living the dream. A 17-year-old International Baccalaureate (IB) student in Mumbai, she juggles academic brilliance with extracurricular polish. Her Instagram is filled with curated shots of European vacations, perfect latte art, and smiling selfies. She speaks confidently in school assemblies about mental health and gender identity. On paper, she's the blueprint for success. But behind the filtered images and honour roll certificates, Teena is unravelling. She has panic attacks at night. She zones out during conversations. Her emotional numbness runs so deep that, in therapy, she struggles to name how she feels. 'My parents are proud of me," she says, 'but I feel like I'll stop existing in their eyes if I'm not the best." She has never told them about the panic. 'They'd probably just hire a better tutor." This isn't an anomaly. It's a pattern. Across India's metros, affluent teens and young adults are suffering from an invisible epidemic of anxiety, emotional dysregulation, identity confusion, and burnout. They are the kids who look sorted, who have access to therapy, gadgets, travel, and liberal education and yet they are often drowning. ANXIETY IN A PALACE Dr Sheba Singh, director at TalkSpace-A Mental Health Studio in Mumbai, notes a recurring profile in her clinic: high-functioning teens who seem fine on the surface but are quietly falling apart. 'They get good grades, they participate in everything, they're articulate," she says. 'But they report feeling empty, disconnected, and sometimes even suicidal." Similarly, Dr Diksha Parthasarathy, a neuropsychiatrist at PSRI Hospital, Delhi describes an emotional landscape riddled with anxiety, panic attacks, self-doubt, and chronic exhaustion. Despite their privilege, these teens express a haunting lack of meaning. 'Affluence creates a paradox, " she explains. 'They have everything except emotional grounding. They are raised to win, but not to feel. This emotional disconnect often stems from the way identity is shaped. From a young age, privileged Gen Z teens are conditioned to perform —academically, socially, even emotionally. According to Mumbai-based psychologist Tanu Choksi, these teens often internalize the belief that their worth is tied to achievements. 'They aren't taught to value rest, failure, or emotional ambiguity. Instead, they learn to fear it," she says. 'Even therapy becomes another checkbox on the success journey." Dev, a 20-year-old Delhi University student, echoes this sentiment. A star student from an elite school, he's now balancing a finance degree with internships and civil service prep. 'If I stop achieving, I feel like I will disappear," he says. Despite his success, he battles perfectionism and impostor syndrome. 'It never feels like I deserve it." Early access to therapy is often lauded as a sign of progress. And in many ways, it is. Singh points out that teens are now more open to discussing their feelings. 'They use terms like burnout, boundaries, trauma. It shows that stigma is decreasing." But both Singh and Choksi warn that this fluency can be deceptive. 'Sometimes therapy becomes performative," Choksi says. Teens talk, but deep emotional work remains unstarted. Parthasarathy agrees: 'Teens who intellectualize their emotions may avoid the actual experience of them." Social media compounds the crisis. 'It's not just screen time," says Singh, 'it's content. Teens are constantly exposed to images of perfection: the perfect body, the perfect life, the perfect activism." This breeds comparison, low self-worth, and emotional fatigue. Teens end up chasing a version of life that doesn't exist. Parthasarathy observes a growing 'lack of contentment" among these adolescents. 'Even when they have strong résumés and supportive families, they feel unsatisfied. There's always another benchmark to meet." Teena admits she deletes posts that don't get enough likes. 'I know it's silly," she says, 'but it still feels like failure." CONDITIONAL LOVE Parental intent is not the issue. Most are loving and invested. But love, when conditional on performance, can feel transactional. Singh highlights this emotional distance: 'Support is often outsourced to tutors, therapists, coaches. But kids crave emotional presence, not just logistical support." Many teens grow up in overprotected environments, buffered from discomfort. This may seem nurturing, but it stunts resilience. 'If failure is always fixed externally," Choksi notes, 'then kids never learn to sit with it." Dev recalls how every problem growing up had a 'solution". A better tutor. A counsellor. A weekend getaway. 'But no one ever just listened," he says. 'It felt like I had to be okay, quickly, so everyone could move on." As for schools, even international ones are not immune. Counsellors are often focused on academic guidance or behavioural correction. 'We need systems that engage with identity, not just grades," says Parthasarathy. 'And students need to feel safe seeking help internally." Many teens avoid the school counsellor's office altogether, fearing judgement or exposure. And even in progressive schools, emotional well-being is often secondary to achievement. BREAKING THE CYCLE So what can be done? All three experts agree: therapy is vital, but it cannot be the only answer. Parents must model emotional honesty. 'Teens need to feel seen," says Singh. 'Not just for their grades or medals, but for their messiness, their vulnerability." Therapists also recommend simple yet consistent activities that build emotional connection. Parthasarathy suggests 'weekly family check-ins" where everyone shares highs and lows without judgment. 'It helps teens feel like emotional expression is normal, not something to be corrected," she says. Singh encourages collaborative routines like cooking together, playing board games, or taking device-free evening walks. 'These shared experiences create space for connection without the pressure of 'talk'," she adds. Choksi recommends reflective journalling, volunteering, or learning a new skill as solo practices help teens reconnect with themselves. Teena and Dev are still navigating their paths. Teena has started opening up, not just in therapy, but to a trusted teacher. Dev has begun journalling. These aren't grand solutions but they're real. And in a culture obsessed with filters, perfection and performance, maybe honesty is the most radical act of all. Divya Naik is an independent writer based in Mumbai.

Surgeon reveals gym mistake that can distort your face if you have lip fillers
Lip filler treatments are booming, especially among Gen Z and Millennials. According to the American Society of Plastic Surgeons, Beautification injectables, including hyaluronic acid (HA) fillers, remain among the top minimally invasive procedures, with hundreds of thousands performed annually. Gen Zers, in particular, are embracing "prejuvenation", a trend toward early, preventive aesthetic treatments. Amid this surge, plastic surgeons are warning of a little-known but alarming consequence: 'face distortion' caused by merging lip fillers with sauna use. This warning has real impact—skip it, and your carefully crafted results might dissolve or shift. Heat+enzymes=Accelerated filler breakdown New York-based plastic surgeon Dr Jimmy Sung told the Daily Mail: 'Right after the lip filler injection, we want patients to avoid saunas to decrease the potential of swelling and bruising and allow the filler to settle. To increase the filler's longevity, we also recommended that patients avoid saunas.' Dr Sung breaks down the science: 'Lip fillers are usually made of hyaluronic acid, which is susceptible to movement and heat degradation. An enzyme known as hyaluronidase can dissolve fillers. This enzyme can be used as a pharmaceutical dissolver, but our body also produces it. When the temperature around our body increases, two things happen: an increase in circulation and activation of our hyaluronidase. This are why lip fillers do not last as long in those who use saunas routinely. ' Thermal exposure accelerates HA degradation, scientific literature stresses that physicians routinely avoid heat-generating treatments shortly after HA injections, as heat breaks down filler integrity. Metabolism, circulation & infection Dr Norman Rowe, board-certified plastic surgeon, adds: 'Fillers and Botox for that matter are eventually metabolized by the body. Anything that increases our metabolism will decrease the lifespan of a filler and Botox. Sauna specifically do just that you would have to be in a sauna for quite a bit in order for this to really play a role, but there really is no way around it.' New York surgeon Dr Barry Weintraub warns: 'Exercising, speaking, which involves muscle use, and regular and prolonged sauna exposure can shorten the lifespan of lip filler. This is because, like exercise, saunas speed the heart rate and dilate the blood vessels, which then increases blood flow, allowing for quicker metabolizing of filler.' His advice: 'Steering clear of a sauna room for at least 48 to 72 hours can prevent some damage to the filler and protect the injection site from a bacterial infection.' Sweating and heat may also heighten infection risk, as bacteria on the face migrate toward fresh injection sites. What to do after lip fillers Here's your post-filler checklist to preserve results and minimize complications: Avoid saunas/steam rooms for at least 72 hours Protect lips from UV, use lip-safe sunscreen Stay well-hydrated, manage swelling and tissue integrity Avoid: Using straws, excessive lip contact, smoking, and consuming extremely hot or cold beverages or hard foods for 24–48 hours post-injection.

SC's mental health guidelines in place since many years at SIU, says Dr Rajiv Yeravdekar
On July 25 this year, the Supreme Court had laid down guidelines applicable to all educational institutions across India with a view to address the rising prevalence of emotional and mental health problems of students. This landmark decision addresses escalating concerns of academic stress and emotional distress culminating in student suicides and calls for the integration of proactive, preventive, and responsive (remedial and supportive) mental health systems across Higher Educational Institutions in India. Dr Rajiv Yeravdekar, provost, faculty of Medical and Health Sciences, Symbiosis International (Deemed University) welcomed the SC judgement and initiatives taken by the government to address the concerns. He said that at Symbiosis International, the provisions laid down have been implemented for several years. Understanding mental health from a public health perspective, customised to young millennials and Gen Z, Symbiosis International (Deemed University) had set up a facility on campus dedicated to providing mental/emotional health services and redressing the same. Considering the stigma around mental health, the facility was named Centre for Emotional Wellbeing (SCEW). 'The Centre has adopted a triple pronged approach towards mental health problems on campus. This includes de-stigmatisation (hence Centre for Emotional Wellbeing rather than Centre for Mental Wellbeing), de-medicinalisation (Hence providing mental health services through a team approach beyond qualified psychiatrists and including psychologist, counsellors, trained teaching and non-teaching staff, life coaches, yoga and movement therapists, and expressive arts practitioners and even peers), and finally educationalisation (commissioning of formal degree programmes in Behavioral Sciences to raise community awareness),' Dr Yeravdekar said. September marks National Suicide Prevention Month and Dr Yeravdekar further mentioned that a host of promotive, preventive, and curative mental health services are provided to students and staff on campus by the Centre, such as Psychological First Aid workshops, Suicide Gatekeeper Training Programme which equips hostel wardens, administrative personnel, security staff, and student leaders to identify early signs of distress and respond effectively. Preventive efforts also include structured student and parent inductions, Emotional Wellbeing Screening and early intervention strategies. All these initiatives aim to enhance psychological preparedness and support among students and their families. Higher educational institutions (HEIs) have been asked to prioritise extracurricular activities, including sports, arts, and personality development initiatives, thereby ensuring a safe and healthy living and learning environment for all students. HEIs are now mandated to depict all such initiatives on institutional websites and notice boards including Suicide helpline numbers in hostels, classrooms, common areas. Failure to take timely or adequate action in such cases, especially where such neglect contributes to a student's self-harm or suicide, shall be treated as institutional culpability, making the administration liable to regulatory and legal consequences. According to Dr Yeravdekar, a unique facility has also been established on campus – the Mind Studio. 'This is a dedicated quiet, serene and calming space created for ensuring mental wellbeing by offering sessions on mindfulness, sensory regulation and cognitive enhancement. Rather than focusing on a curative approach alone, we have adopted a holistic approach for promotion of Mental Health, by encouraging students to engage in physical activity pursuits,' he said.
