A Cancer Survivor Questions His Vitamins

Meet a 68-year-old man, fit and active, who recently underwent prostate cancer treatment. After a successful surgery in 2023 and finishing radiation, he faces a new battle—his daily vitamins. For years, he's relied on Centrum Silver multivitamins, fish oil, calcium, and vitamin D, but now he’s filled with doubt.

The Hidden Dangers of Supplements

In his quest for health, he stumbled upon some shocking news: selenium and vitamin E, both present in his multivitamin, could actually increase prostate cancer risk! Conflicting studies about fish oil only added to his concerns. Should he continue taking these supplements, or stop altogether? And could they have worsened his condition?

Dr. Roach Weighs In

In a detailed response, Dr. Roach sheds light on the potential dangers of these supplements. He explains that vitamin E has been linked to a staggering 17% increased risk of prostate cancer according to a study that was halted midway for safety reasons. He strongly advises against taking vitamin E for anyone with a history of prostate cancer.

As for fish oil, the evidence is murky. While some studies suggest it may elevate risks, others show no connection. Dr. Roach suggests avoiding fish oil unless it's recommended for specific health needs.

Diet: The Best Medicine?

Dr. Roach emphasizes the importance of a healthy diet over relying on supplements. A plant-rich diet loaded with fruits, vegetables, and whole grains is vital for prostate cancer survivors. While lean meats are fine, he advises cutting back on unhealthy fats and processed meats.

Another Health Concern

In a separate case, a 78-year-old man is seeking clarity on whether to fast for a metabolic blood test as advised by his nephrologist. Typically, fasting leads to more accurate test results, yet the doctor insists he shouldn’t.

Dr. Roach reassures him to follow his nephrologist's guidance. Non-fasting tests reflect the patient’s usual condition, and while diet might slightly affect creatinine levels, it's not a major concern.

Your Health Choices Matter!

Both stories highlight critical health decisions that can have serious implications. Whether you're a cancer survivor or managing other health conditions, the choices you make about supplements and diet can significantly impact your wellbeing. It's essential to stay informed and consult healthcare professionals before making any changes to your regimen.
