Feeling a bit low on gloomy days? You are not alone. When sunlight is scarce, our bodies miss out on producing an essential nutrient: vitamin D.
Recent studies show that this powerhouse vitamin does more than just strengthen your immune system. It might also serve as a secret weapon against colorectal cancer.
In a groundbreaking study, researchers at Semmelweis University in Budapest analyzed data from 1.3 million adults. Their findings were striking: people with higher levels of vitamin D in their blood (80 ng/mL) had a 25% lower risk of developing colorectal cancer than those with lower levels (10 ng/mL).
And this is not the only study highlighting vitamin D’s potential benefits. The Nurses’ Health Study in the United States found that women who consumed around 477 IU of vitamin D daily reduced their colorectal cancer risk by 58% compared to those who only took in 76 IU.
Similarly, the Iowa Women’s Health Study showed that women who increased their vitamin D and calcium intake cut their colorectal cancer risk in half.
Experts explain that vitamin D acts like a superhero for the body, suppressing cancer cell growth, reducing inflammation, and even triggering cancer cells to self-destruct through a process called apoptosis.
It also supports the immune system and may help prevent the formation of high-risk polyps in the colon.
While our bodies naturally produce vitamin D when exposed to sunlight, many of us spend most of our time indoors. So, how can you maintain healthy vitamin D levels? Through food.
Fatty fish like salmon, mackerel, and tuna are excellent sources. Other good options include egg yolks, yogurt, vitamin D-fortified soy milk, and shiitake mushrooms.
The tip is that sun-dried mushrooms offer an even higher concentration of vitamin D. Incorporating these foods into your diet is a simple and tasty way to boost your vitamin D intake.
However, moderation is key. Excessive vitamin D intake can cause unwanted side effects such as hypercalcemia, kidney stones, and digestive issues.
If you are a woman who may become pregnant, it is especially important to monitor your intake. Most adults under 50 should aim for 5 µg (200 IU) daily, while those over 50 should target 10 µg (400 IU). Pregnant and breastfeeding women should add an additional 5 µg to these amounts.
Maintaining sufficient vitamin D levels could be a simple yet powerful strategy in preventing a severe disease like colorectal cancer. If you cannot spend time in the sun, filling your plate with vitamin D-rich foods is easy to support your health. Your future self will thank you.
