Lowering cancer risk is not just about medical treatments your daily food habits also play a major role. Experts have argued that a small but steady change in what and how you eat can overall have a tremendous positive influence on the long-term health of whoever you are. Cancer experts currently lay stress on the basic diet tips and conscious fasting as potent instruments of prevention. In this article, Cancer Surgeon Dr Arun Kumar Giri, Director - Surgical Oncology, Aakash Healthcare, explains how to lower cancer risk naturally by simple diet and fasting hacks and making healthy changes in lifestyle.
Dr Giri notes the direct correlations between nutrition and levels of inflammation, metabolism, and cell health in general. He says, "Ancient accruing knowledge on cancer continues to point out the feasibility of daily eating patterns in establishing a substantial effect on cancer risk over the long term, and several basic interventions have been found to have a strong effect on cancer prevention. By maintaining a healthy diet that gives priority to whole foods and minimally processed foods, inflammation of cells lessens, metabolic stability is maintained and a habitat that cancer cells enjoy developing in is made less favourable." This implies that the more natural and real the foods you consume, the more your body is able to defend itself.
Vegan food contains the nutrients and antioxidants your body requires. The expert recommends, "The plant-based diets and more so the leafy greens, cruciferous vegetables, seasonal fruits, whole grains, nuts and legumes are good sources of the sustained availability of the antioxidant, fibre and phytonutrients that assist in repairing the cells and enhancing the natural surveillance functions of the immune system. Such foods aid in cell repair, reduce inflammation and boost immunity."
Dr Giri emphasises the necessity of minimising unhealthy food options. Lifestyle change through the reduction of frequent consumption of high-sugar foods, deep-fried food, processed meats, and excessive red meat reduces the exposure to carcinogenic compounds and allows insulin levels to remain stable, which is increasingly associated with lower risk of cancer. Reducing these foods will aid in minimising toxins and staying in good metabolic condition.
Mellowed routine starvation improves recovery in your body. There have also been beneficial results associated with incorporation of gentle fasting practices. Intermittent fasting like 12-14 hours of overnight fasting enables the body to go into a metabolic state that helps the body to increase its insulin sensitivity, decrease oxidative stress, and increase autophagy, a natural process of clearing the damaged parts of the cell that would otherwise lead to malignant transformation. He also recommends early dinners to support circadian rhythm and hormonal balance.
Good fats, hyperhydration and fermented foods matter a lot. As Dr Giri explains, "Hydration is also very critical fermented foods like yoghurt, kefir, and homemade pickles lead to a healthier gut microbiome, which is now also known as a significant regulator of immune reaction and cancer risk." He adds that regular schedules, colourful meals, less stress, and adequate sleep are essential.
Dr Gir is the most eloquent in summarising the prevention of cancer by diet. It is not possible to protect adequately with any diet and food pattern. The described approach to nutrition includes the small and sustainable daily modifications which are capable of lowering the exposure risks and improving overall resilience. Consuming fresh fruits in the morning, home-cooking meals, increasing the amounts of fibre in the diet, decreasing alcohol intake, eating dinner early enough, and going without supper can assist an individual in reaching the needed control when it comes to matters of long-term health.
A body resistant to cancer can be made through simple, consistent, and regular practices, i.e., eating more plan-based foods, eating early, practising conscious fasting, and home-cooked food.
