New study reveals very bad news for bread lovers

The Chinese authors of this study deserve credit for a very careful and thorough study.  In the end, however the results are no different from less well-controlled  previous studies:  Weak effects.  All the relationships were marginal, meaning that it would be a rare person who suffered ill effects from (say) eating bread.  A bread enthusiast living to be 100 could be expected

There are few things in this world as comforting as a fresh piece of bread straight from the oven.

Spread with some lashings of butter, a dollop of jam or a scrape of vegemite, most of us have grown up with this delicious snack and many enjoy it as part of our daily diet.

While most of us can admit that consuming nothing but bread may leave us with more vitamin deficiencies that a scurvy-riddled pirate, we may not realise the impact our carboholic tendencies are having on our health.

According to a brand new study featured in Nutrients medical journal, the humble loaf of white bread has sadly been found to increase the risk of developing colorectal cancer (CRC), also known as bowel cancer, regardless of genetic factors.

Alcohol was also found to be a contributing factor in a person’s chance of developing this cancer, in addition to the other negative impacts of the drug.

Researchers from the Zhejiang University School of Medicine in China analysed 139 dietary factors and their impact on the risk of developing bowel cancer.

The 118,210 participants from the UK Biobank cohort completed online questionnaires about their food intake.

Following up with their clients after an average of 12.8 years, researchers identified that both white bread and alcohol increased the risks of bowel cancer, while six other vitamins and minerals – fibre, calcium, magnesium, phosphorus, manganese, and carbohydrate – decreased the risk of developing CRC.

The study found that the overall risk was influenced by both a mix of some genetic characteristics, as well as diet and lifestyle habits.

“After a mean follow-up of 12.8 years, we identified 1466 incidents of CRC among 118,210 UK participants,” the study read.

“Of these, 842 were colon cancer and 359 were rectal cancer. The mean age of the 1466 CRC patients was 55.87 years and almost 44.6% of the study population was male.

“Compared to the general population, CRC cases were more likely to be male and white, older, and less educated, and to have a higher TDI (tolerable daily intake), more family history of bowel cancer, a high BMI, less physical activity, more smoking, and a higher prevalence of diabetes at baseline.”

Misagh Karimi, M.D., a medical oncologist and colorectal cancer specialist, was not involved in the study but offered his reaction to its results.

“The findings of this study reaffirm the well-established connection between lifestyle and dietary choices and the prevention of colorectal cancer,” he told Fox News.

“These findings emphasise the critical importance of adopting a healthy lifestyle and dietary habits, which include limiting alcohol consumption and choosing a diet rich in high-fibre foods to mitigate the risk of cancer.”

While the doctor praised the study for involving a large amount of people, he pointed out that it was focused on a European population and further studies might be needed.

“This study also stands out because of its size and design,” Dr Karimi said.

“It involved a large sample population of 500,000 middle-aged people, a long follow-up period and a comprehensive assessment of dietary factors.

“As the researchers state, analysis was limited to a European population. To ensure the applicability of these findings to diverse populations, further studies are needed to validate these results on a wider population.”

Bowel cancer was the third most commonly diagnosed cancer in Australia in 2018, according to Cancer Australia.

In 2020, bowel cancer was the second most common cause of cancer death in Australia, with 5354 (2847 males and 2507 females).

Some common symptoms include a change in bowel habits, blood in stools, abdominal pain, cramping, bloating, weight loss, lumps in the rectum, unexplained fatigue and blood in the urine.

Earlier this year, another study published in the PNAS journal from a research team in Hangzhou, China, found that hot chips and other deliciously fried carbohydrate-laden foods may have a negative impact on mental health.

The study found that these types of meals may be linked to higher rates of anxiety and depression, with the impact found to be more pronounced in “young men, and younger consumers in general”.

The research demonstrate that the frequent consumption of fried foods – especially fried potatoes – was linked with a 12 per cent higher risk of anxiety and a 7 per cent higher risk of depression, compared to people who did not eat fried foods.

However, nutrition experts explained that the results are preliminary, and it is not necessarily clear whether the fried foods were driving mental health issues, or people experiencing symptoms of depression or anxiety turned to fried foods for comfort.

Fried potatoes specifically were found to have a 2 per cent increase in risk of depression over “fried white meat”, such as fried chicken.
