:## Vitamin C and Cancer Risk: A Complete Look
Vitamin C is an essential nutrient widely recognized for its role in protecting the body against oxidative stress and supporting immune health. According to a comprehensive umbrella review published in 2022 in Nutrients[1], low vitamin C intake or deficiency is linked to a notably higher risk of developing several cancers, including those of the stomach, oesophagus, and lungs. This review analyzed multiple studies and concluded that higher dietary or supplemental vitamin C consistently correlates with a lower incidence of these cancers.
Vitamin C deficiency and oesophageal cancer risk
Table of Contents
The oesophagus is the tube that connects your throat to your stomach. Research shows that people who consume more vitamin C have a lower chance of developing oesophageal cancer, which affects this vital passageway. A major study[2] found that every 50 mg increase in daily vitamin C intake – roughly what you’d get from an orange-was linked to a 10-13% decrease in the risk of oesophageal cancer. This protection was seen across all main types of this cancer. Vitamin C’s antioxidant effects help neutralize harmful molecules that can damage the delicate cells lining the oesophagus, preventing changes that can lead to cancer.
Vitamin C’s role in stomach cancer prevention
Stomach cancer, sometimes called gastric cancer, has been connected to dietary factors and vitamin deficiencies. Several significant studies, including large-scale population-based ones like the US cancer Prevention Study II and research conducted in Linxian, China, have found that people with higher vitamin C intake have a lower risk of developing stomach cancer. Vitamin C seems to help by acting as an antioxidant, reducing inflammation, and preventing the formation of precancerous lesions in the stomach. Ensuring adequate vitamin C may slow down or even block processes that can lead to cancer in this organ.
The link between Vitamin C and lung cancer
Lung cancer remains a significant health concern.Analysis of studies suggests that adequate vitamin C intake may play a protective role. [3] Vitamins are nutrients found in the foods we eat, needed for growth, metabolism, and nervous system activities.
