‘Cut out booze altogether to avoid risk of cancer’

"This means that for those kids that you can, in school healthcare, catch and if you can change their trajectory during puberty you can do a lot for their risk of colon cancer".

Mirroring a 2015 World Health Organization warning that linked the consumption of processed and red meats to forms of cancer including bowel, the report recommended a diet featuring wholegrains, vegetables, fruit and pulses.

The report also advises satisfying nutritional needs through diet alone, instead of counting on supplements.

"It's unlikely that there are "magic bullet" specific foods or nutrients that in themselves cause or protect against cancer", Dr. Kate Allen, WCRF executive director of science and public affairs, said in a blog post.

WCRF says one in six deaths globally are already caused by cancer.

Their analysis linked obesity or being overweight to 12 cancers, including those affecting the liver, ovary, prostate, stomach, mouth and throat, join bowel, breast, gallbladder, kidney, oesophagus, pancreas and womb. As many modifiable risk factors are shared between cardiovascular disease and cancer, researchers broadened the scope to assess the impact this intervention may have had on cancer risk. Red meat's cancer risks include colorectal, lung, pancreatic, and nasopharyx. It also encouraged people to reduce consumption of fatty and sugary fast foods, as the number of new cancer diagnoses is expected to jump to 24 million by 2035.

Avoiding obesity as well as maintaining a stable weight in middle adulthood could help prevent certain cancers in women, according to new research presented at this year's European Conference on Obesity (ECO) in Vienna, Austria (23-26 May).

The aim of the report is not to worry people, she said.

A separate presentation at the conference suggests that obesity plays a part in malignant melanoma - a form of skin cancer that is the fifth most common in the United Kingdom, causing 2,000 deaths a year.

Caroline Cerny, the lead of the Obesity Health Alliance comprised of over 40 health charities, medical colleges and campaign groups, said carrying excess weight cannot only raise the risk of cancer, but also type 2 diabetes, heart and liver disease and mental illness. WCRF recommends that people cut down on fast and processed convenience foods.

Emma Shields, from Cancer Research U.K. told Newsweek: "Although it can seem as though we're constantly bombarded with new messages about cancer prevention, this expert report highlights how remarkably consistent the advice has stayed".

Living an active life full of exercise and eating a diet packed with whole grains, vegetables, fruit, and beans will also keep cancer at bay. It's what you do most days that matters.
