ISLAMABAD, June 20 (Online): Our diet is one of the environmental factors that can influence our risk of cancer.
\nPast studies show following a healthy diet may lower a person\u2019s cancer mortality risk, while eating unhealthy foods may increase a person\u2019s risk of dying from cancer.
\nResearchers from the Nagoya University Graduate School of Medicine in Japan have found eating small fish whole may reduce all-cause and cancer mortality risk in Japanese women.
\nThere are many factors involved in a person\u2019s risk of both developingTrusted Source and dying from cancer. Previous research shows that one of those influencers is what we eatTrusted Source.<\/p>\n
Past studies have linked following a healthy dietTrusted Source such as the Mediterranean dietTrusted Source to a lower risk of dying from cancer. On the flip side, following an unhealthy diet high in sugarTrusted Source, saltTrusted Source, and ultra-processed foodsTrusted Source may increase a person\u2019s cancer mortality risk.<\/p>\n
Now, researchers from the Nagoya University Graduate School of Medicine in Japan have found eating small fish whole may reduce the risk of death by cancer or any other cause in Japanese women.<\/p>\n
The study was recently published in the journal Public Health Nutrition.<\/p>\n
Significant cancer death reduction by eating small fish whole
\nFor this study, researchers analyzed food frequency questionnaire data from more than 80,000 participants \u2014 about 34,500 men and 46,000 women \u2014 between the ages of 35 and 69 in Japan. Based on the questionnaires, scientists noted how frequently study participants ate small fish whole.<\/p>\n
Researchers followed the participants for an average of nine years, during which about 2,400 participants died with about 60% attributed to cancer.<\/p>\n
At the study\u2019s conclusion, scientists discovered there was a significant reduction in all-cause and cancer death among female participants who habitually ate small fish whole.<\/p>\n
When researchers factored in lifestyle habits that may impact mortality risk, such as smokingTrusted Source, BMITrusted Source, and alcohol consumptionTrusted Source, they found female participants who ate small fish frequently were less likely to die from any cause.<\/p>\n
\u201cPrevious studies have revealed the protective effect of fish intake on health outcomes, including mortality risks,\u201d explains Chinatsu Kasahara, PhD, professor in the Department of Preventive Medicine at the Nagoya University Graduate School of Medicine in Japan and lead researcher of this study. \u201cHowever, few studies have focused on the effect of the intake of small fish specifically on health outcomes. I was interested in this topic because I have had the habit of eating small fish since childhood. I now feed my children these.\u201d<\/p>\n
Smaller fish have the benefits of being sustainable as they are not normally overfished like larger fish and generally have lower levels of mercury.<\/p>\n
\u201cI regularly recommend the consumption of small fish due to their impressive nutritional value and low levels of toxic mercury compared to large fish,\u201d Molly Rapozo, RDN, registered dietician nutritionist & senior nutrition and health educator at Pacific Neuroscience Institute in Santa Monica, CA, who was not involved in this study, told Medical News Today.<\/p>\n
\u201cSmall fish are a component of traditional Japanese and Mediterranean diets, which are both touted for their longevity,\u201d she said.<\/p>\n
The health benefits of eating small fish
\nIn addition to being a healthy protein source, small fish also provide a variety of nutritional benefits including omega-3 fatty acids and micronutrients such as calcium, vitamin A, iron, zinc, and vitamin B12.<\/p>\n
\u201cThe health benefits that have been associated with fish overall such as being a rich source (of) essential and protective nutrients such as protein and healthy fats such as omega-3 fatty acids, as well as a source (of) calcium from the bones and a host of other vitamins and minerals has been pretty consistent in the research,\u201d Monique Richard, MS, RDN, LDN, a registered dietitian nutritionist and owner of Nutrition-In-Sight explained to MNT.<\/p>\n
\u201cOften when someone is eating small cold-water fish sources they are also choosing other foods that complement the health benefits offered by fish such as fruits, vegetables, and whole grains,\u201d Richard continued.<\/p>\n
\u201cTiny fish do not typically lend themselves well to being battered, deep fried, and served with french fries but are more delicate as well as naturally portion controlled. They tend to be more rich and flavorful in taste to the palate which lends itself to slower eating, savoring the bites and possibly needing less to feel satisfied,\u201d she said.<\/p>\n
\u201cThis study adds to the existing evidence of fish consumption and cancer mortality. We\u2019ve seen in previous studies that regular fish intake is associated with a reduced risk of gastrointestinal cancersTrusted Source, as well as being a potential benefit for cancer survivorsTrusted Source who have diets high in oily fish.\u201d
\n\u2014 Molly Rapozo, RDN<\/p>\n
\u201cThis kind of research is important because what we eat has a significant impact on chronic disease. Lifestyle changes, such as food choices, are an opportunity to decrease the risk of early death and disability. Evidence-based dietary strategies offer a practical approach to reducing the burden of chronic diseases, including cancer, and improving longevity,\u201d Rapozo said.<\/p>\n
Importance of battling cancer through diet
\nMNT also spoke with Anton Bilchik, MD, PhD, surgical oncologist, chief of medicine, and director of the Gastrointestinal and Hepatobiliary Program at Providence Saint John\u2019s Cancer Institute in Santa Monica, CA, about this study.<\/p>\n
Bilchik said he found the study interesting that eating small fish whole may offer protective factors against the development of cancer.<\/p>\n
\u201cBut I think that this is very early in terms of \u2026 what exactly it means, what\u2019s a whole small fish in terms of the anti-cancer chemicals, vitamins, and the big buzzword in cancer right now is inflammationTrusted Source. So within a whole fish, are there various compounds and vitamins that have an anti-inflammatory effect? But there\u2019s still a lot to be worked out,\u201d he said.<\/p>\n
Because many young people are being diagnosed with cancer, particularly colorectal cancer, Bilchik said it is important for researchers to continue to find new ways of protecting the body from cancer, including through what we eat.<\/p>\n
\u201cThe usual causes such as obesity, smoking, family history, are not commonly found in these young people that are being diagnosed,\u201d he explained. \u201cAnd so the only other potential linker can be looked at is diet at a young age \u2014 whether these individuals that are getting early onset cancer, such as colorectal cancer, are eating processed food, are being exposed to environmental factors that may influence cancer at a young age.\u201d<\/p>\n
\u201cSo there\u2019s a lot of work that needs to be done to better understand why so many young people are being diagnosed with cancers, particularly colorectal cancer,\u201d Bilchik added.<\/p>\n","protected":false},"excerpt":{"rendered":"
