Kolkata, March 17, 2025: Dr. Vanita Rahman, an internal medicine physician, certified nutritionist, and fitness expert with the Physicians Committee for Responsible Medicine (PCRM), delivered a lecture at Loreto College, Kolkata. Her address focused on the role of a plant-based diet and lifestyle interventions in the prevention and management of breast cancer, polycystic ovary syndrome (PCOS), and thyroid disease—three prevalent health concerns among Indian women.
Kolkata has witnessed a sharp rise in breast cancer cases, with cervical and breast cancer patients together accounting for nearly 60% of all female cancer cases in the city. Meanwhile, PCOS affects between 2% and 35% of women in India, and thyroid disorders impact an estimated 42 million Indians, disproportionately affecting women due to hormonal fluctuations during puberty, pregnancy, and menopause. Addressing these alarming statistics, Dr. Rahman emphasized that nutrition isn’t just a factor—it’s a powerful tool in disease prevention and recovery. A plant-based diet has been shown to lower cancer risk, improve insulin sensitivity in PCOS, and support thyroid function.

“The foods we eat and the lifestyle choices we make have a profound effect on our health. Extensive research confirms that a plant-based diet, rich in whole grains, fruits, and vegetables, actively reduces breast cancer risk, improves insulin sensitivity in PCOS, and supports thyroid function,” said Dr. Rahman. “Empowering women with the knowledge to make informed dietary and lifestyle choices is a crucial step in combating these health challenges.”
During her lecture, Dr. Rahman shared scientific evidence supporting plant-based nutrition. Studies have demonstrated that women who consume a low-fat, plant-based diet have a 23% lower risk of breast cancer recurrence and a 17% lower risk of dying from the disease.
Beyond dietary recommendations, Dr. Rahman emphasized the importance of holistic lifestyle modifications, including regular physical activity and maintaining a healthy weight.

The session at Loreto College saw enthusiastic participation from students and faculty members, who engaged in a dynamic discussion about the science behind plant-based nutrition and its practical application in health care. As more research highlights the power of plant-based nutrition, it’s time for a shift in how we approach health care. Prevention must be prioritized, and nutrition should be at the forefront of medical education and public health initiatives.
