Are Your Daily Supplements Putting You at Risk for Cancer? Find Out Which Ones Experts Warn Against!
- Replies 0
In an age where health consciousness is at an all-time high, many of us are reaching for that bottle of vitamins or dietary supplements to give our bodies a perceived edge in the battle against illness and aging. But could this well-intentioned habit be doing more harm than good? According to recent warnings from health experts, the answer might be more complex than we'd like to think.
Nichole Andrews, an oncology dietitian based in Washington State, has raised concerns about the potential risks associated with taking certain common supplements, particularly when consumed in high doses. While vitamins like C and B12 are essential for maintaining a healthy immune system and aiding in the formation of red blood cells, respectively, the 'more is better' approach to supplementation could be misguided and even dangerous.
The issue at hand is that the body has a limited capacity to process these vitamins, and when taken in excess, they can't be excreted quickly enough. This can lead to a buildup in the bloodstream, where these surplus nutrients may begin to attack healthy cells and potentially stimulate the growth of cancerous tumors. Andrews starkly points out that at high levels, these vitamins 'will harm your cells.'
This warning is particularly alarming considering the widespread use of dietary supplements. In the United States, over half of the population reports taking at least one dietary supplement, and the accuracy of labeling on these products is questionable. Experts estimate that up to 90 per cent of these supplements may be incorrectly labelled, leaving consumers in the dark about the true dosages they're ingesting.
The lack of strict regulation by authorities like the United States Food and Drug Administration further complicates the issue, as it's challenging to determine the actual content and daily value of the supplements we take. This regulatory gap underscores the importance of sourcing nutrients from food whenever possible, as the risk of reaching toxic levels through diet alone is significantly lower.
Studies have shown that when nutrients like vitamin C are consumed through food, they act as antioxidants, helping to neutralize free radicals—unstable molecules that can damage DNA and disrupt cell function. However, when these same nutrients flood the bloodstream in supplement form, they can contribute to the formation of these harmful molecules.
Research has highlighted some concerning associations. For instance, a study found that cancer patients and those at increased risk who took high doses of vitamins C and E experienced accelerated tumor growth due to the formation of new blood vessels within the tumors. Another study from The Ohio State University revealed that male smokers taking high doses of vitamins B6 and B12 faced a significantly increased risk of lung cancer.
While these studies are observational and don't establish a direct cause-and-effect relationship, they do suggest a need for caution. The takeaway from experts like Andrews is clear: unless you have a specific deficiency diagnosed by a healthcare professional, you're likely better off getting your vitamins and minerals from the food you eat.
Foods rich in vitamin C, such as citrus, and those high in vitamin B12, like red meat, eggs, and fish, can provide you with the necessary nutrients without the risk associated with high-dose supplements. And when it comes to other nutrients like calcium and fiber, which have been linked to a reduced risk of certain cancers, the advice remains consistent—food sources are preferable to supplements.
For our members here at the Seniors Discount Club, this information is particularly pertinent. As we age, we may be more inclined to turn to supplements to fill nutritional gaps or boost our health. However, it's crucial to consult with a healthcare provider before starting any new supplement regimen, especially if you're already managing health conditions or taking other medications.
We invite you to share your thoughts and experiences with dietary supplements. Have you noticed any health changes since starting or stopping supplements? Do you prefer to get your nutrients from food, or do you rely on pills? Let's discuss in the comments below how we can all make informed choices for our health and well-being.
