世界保健機関（WHO）傘下の専門組織、国際がん研究機関（IARC）は10月26日、ハムやベーコン、ソーセージなどの加工肉を1日50グラム食べると、大腸がんになるリスクが18％高まるなどとする研究結果を発表した。赤身肉についても発がん性の恐れがあるという。
発表によると、IARCの専門家らは800以上の研究から、加工肉や赤身肉の発がんリスクを分析。加工肉はIARCの発がん性の基準で、タバコやアスベストなどと同様に発がん性が最も高い「グループ1」に分類された。専門家は「人によっては、加工肉の摂取による大腸がんのリスクは小さいままであるが、このリスクは肉の摂取量によって高くなる」と指摘している。
一方で、肉の栄養価についても言及しており、バランスよく食事をする必要性を訴えた。
イギリスがん研究所はこの発表について、イギリス政府が推奨している赤身肉及び加工肉の1日あたり摂取量を70グラム以下に抑えるべきとする助言をふまえ、日々の食事の改善例をインフォグラフィックで紹介している。
「あなたの寿命を縮める11の方法」
1. 寿命を縮める食べ物を選ぶ(01 of11)
Over the years, there\'s been a lot of debate related to diet and longevity. But most experts agree that a diet low in sugar and refined carbohydrates is best. And some studies show that eating a traditional Mediterranean diet can add years to your life. (credit:Shutterstock)
2. コレステロールをチェックしない(02 of11)
Just like high blood pressure, high cholesterol can also increase your risk of heart disease and stroke. Therefore it\'s a good idea to have your cholesterol checked to see whether you need to undergo certain lifestyle changes or even possibly take some kind of cholesterol-lowering medication. For more information about cholesterol and saturated fats, go here.\n\nEating certain foods, such as beans, which are rich in fiber and antioxidants, can help lower cholesterol.\n\n (credit:Getty Images)
3. アルコールを、ドラッグや処方薬と一緒に飲む(03 of11)
Even drinking wine with dinner and then taking prescription sleep aides can be a lethal combination. A U.S. Department of Health and Human Services study found 5.8 percent of people age 50 to 59 used illicit drugs in 2010, up from 2.7 percent in 2002. (credit:Alamy)
4. 糖尿病の検査はしない(04 of11)
The number of Americans with Type 2 diabetes is expected to rise from 30 million today to 46 million by 2030, when one of every four boomers -- 14 million -- will be living with this chronic disease, according to the National Center for Chronic Disease Prevention and Health Promotion.

Untreated diabetes can lead to blindness, amputations and clogged arteries that can cause heart attacks and strokes. The test to determine whether you are diabetic is a simple blood test; you should remind your doctor to include it in your annual physical. (credit:Alamy)

5. 体重を増やす(05 of11)
More than one out of every three boomers -- more than 21 million -- will be considered obese by 2030. Already, we are the demographic with the highest and fastest-growing rate of obesity. As we age, our metabolism slows down and we burn fewer calories -- if we don\'t alter our eating and exercise patterns, weight gain is inevitable. \n\nObesity can lead to high blood pressure, heart disease, and a host of other life-threatening ailments. Losing just 10 percent of your body weight has health benefits, so consider that as a goal. (credit:Alamy)
6. 心臓病の兆候を無視する(06 of11)
No chest pain doesn\'t mean no heart attack. Women having heart attacks frequently report experiencing a feeling of indigestion and extreme fatigue, while some men say they feel a fullness or a squeezing pain in the center of the chest, which may spread to the neck, shoulder or jaw. When a diabetic has a heart attack, the pain is often displaced to other areas such as the lower back. (credit:Alamy)
7. 睡眠時間を十分にとらない(07 of11)
Try as you might, you just can\'t stay asleep, right? You pass out before \"60 Minutes\" is over, but then wake up around midnight and count sheep until the alarm goes off. If that sounds like you, you aren\'t alone. The U.S. Centers for Disease Control and Prevention says that boomers report not getting enough sleep between one and 13 nights each month.\n\nIs it life-threatening? In itself, no. But as soon as you slip behind the wheel bleary-eyed, you are putting yourself and others at risk. Your reflexes are slower, you pay less attention and you could become one of the more than 100,000 Americans who fall asleep at the wheel and crash each year. And the National Highway Traffic Safety Administration says that\'s a conservative estimate, by the way. Driver fatigue results in an estimated 1,550 deaths, 71,000 injuries and $12.5 billion in monetary losses. (credit:Alamy)
8. 運動はしない(08 of11)
AARP says the minimum you need to stay healthy are muscle-strengthening exercises twice a week, plus 2.5 hours a week of moderate activity like walking or 75 minutes a week of a more intense activity like jogging. Exercise is also good for your memory: Just one year of walking three times a week can increase the size of the hippocampus, the part of the brain that\'s key to memory. (credit:Alamy)
9. なんでも心配する(09 of11)
We\'re talking about stress with a capital S. Boomers are the sandwich generation, caught in the middle of caring for our parents and our children. We were deeply affected by the recession and boomers have the highest rates of depression by age demographic. Unless we unload, we are going to implode. (credit:Alamy)
10. お腹周りを太らせる(10 of11)
It isn\'t just our extra weight; it\'s where we carry it. An excess of visceral fat causes our abdomens to protrude excessively. We call it a \"pot belly\" or \"beer belly\" or if the visceral fat is on our hips and buttocks, we say we are \"apple shaped.\" Cute names aside, scientists now say that body fat, instead of body weight, is the key to evaluating obesity. And guess what? It\'s all bad. (credit:Alamy)
11. 喫煙を続ける(11 of11)
Gallup found that baby boomers between the ages of 44 and 54 reported higher levels of smoking than those immediately younger or those who are older. Hard to imagine that they haven\'t gotten the word yet about the risks cigarettes carry. (credit:Alamy)
