In the quest for health and longevity, many of us turn to the supplement aisle, hoping to find the magic pill that will ward off disease and keep us feeling young. However, a top dietitian specialising in nutrition for cancer patients has sounded the alarm on the potential dangers of these seemingly benign pills and potions. With millions of Australians regularly consuming dietary supplements, it’s crucial to understand the risks involved and the importance of approaching these products with caution.
Nichole Andrews, a Washington-based dietitian with a significant following on social media, has warned that the majority of vitamins and supplements we take could be detrimental to our health. She points out that while many supplements, such as apple cider vinegar, collagen, and vitamin C, are marketed for their health benefits, excessive doses can lead to imbalances and even increase the risk of cancer.
Apple cider vinegar capsules, for example, are often touted as a weight loss aid and a remedy for high blood pressure. However, Andrews emphasises that the evidence for these claims is weak, primarily based on studies conducted in petri dishes rather than in humans. She cautions that these capsules can irritate the digestive system and damage tooth enamel due to their high acidity. Instead of reaching for a supplement, Andrews suggests natural alternatives like lemon water or fermented foods such as kimchi or sauerkraut to aid digestion.
Collagen supplements are also on Andrews’ list of products to avoid. While collagen is vital for skin and joint health, the body typically produces enough if you maintain a well-balanced diet. Excessive collagen intake can interfere with nutrient absorption. Andrews recommends getting your collagen from natural sources like chicken, fish, eggs, citrus fruits, and berries, which are also high in vitamin C.
Biotin, or vitamin B7, is another supplement that Andrews advises against in pill form. Found naturally in eggs and bananas, biotin is often recommended for strengthening hair and nails. However, too much biotin from supplements can interfere with blood tests and may not be necessary if you’re consuming a balanced diet rich in eggs, nuts, leafy greens, avocados, and sweet potatoes.
Turmeric, praised for its anti-inflammatory and pain-reducing properties, can cause stomach irritation and affect liver function at high levels. Andrews suggests incorporating turmeric into meals, such as curries or smoothies, with healthy fats to enhance absorption, rather than taking it as a supplement.
Vitamin C supplements are also a concern. While vitamin C is crucial for wound healing and maintaining healthy skin, blood vessels, bones, and cartilage, excessive intake can lead to kidney stones and digestive issues. Andrews stresses that whole fruits and vegetables like oranges, strawberries, bell peppers, and broccoli provide ample vitamin C without the risks associated with supplements.
Recent studies support Andrews’ concerns. A 2023 study published in The Journal of Clinical Investigation found that antioxidants like vitamins C and E could help tumours grow by boosting a protein that increases blood supply to tumours. While these vitamins are beneficial at the levels found in food, taking them in supplement form could potentially aid cancer growth.
