Common Vitamin Found in Nuts and Seeds: In recent years, the spotlight on nutrition and disease prevention has only grown brighter. But now, a major new study is adding a surprising twist: a simple snack of nuts and seeds may play a role in reducing the risk of skin cancer. Researchers have found that a common vitamin found abundantly in foods like almonds, pistachios, sunflower seeds, and cashews not only boosts overall health but may also protect the skin from harmful UV damage.
The vitamin in question is Vitamin B3, also known as niacin or nicotinamide. This essential nutrient has long been recognized for supporting healthy nerves, skin, and digestion. But recent research shows its role could be far more powerful — potentially reducing the risk of skin cancer and helping people with a history of the disease prevent recurrence.

FAQs
1. How does Vitamin B3 help prevent skin cancer?
Vitamin B3 (niacin or nicotinamide) supports the skin’s natural ability to repair DNA damage caused by UV rays. It also reduces immune suppression triggered by sun exposure, lowering the chances of abnormal cell growth that can lead to cancer.
2. Can eating nuts and seeds provide enough Vitamin B3 for protection?
Nuts and seeds are excellent natural sources of Vitamin B3, but the amounts may vary. For therapeutic benefits, especially in preventing skin cancer recurrence, supplements are often recommended. A healthcare provider can guide on dosage.
