Prevention first<\/h2>\n\n\n\n
Garattini\u2019s authority comes from a long career in medicine, not from a wellness trend. That makes his message feel sharper, because he is not claiming that cancer is simple or that every tumor can be avoided.<\/p>\n\n\n\n

Prevention often begins before the hospital, in ordinary choices that seem small until they add up.<\/p>\n\n\n\n
Why 40% matters<\/h2>\n\n\n\n
A 2024 American Cancer Society analysis led by Farhad Islami found that four in ten cancer cases and about half of cancer deaths among U.S. adults age 30 and older were tied to modifiable risk factors. <\/p>\n\n\n\n
\u201cModifiable\u201d simply means risks that can be changed or reduced, even if money, neighborhood conditions, work schedules, and access to care make that easier for some people than for others.<\/p>\n\n\n\n
Smoking was the largest factor in that analysis. Excess body weight, alcohol, ultraviolet radiation, physical inactivity, diet, and infections also appeared in the list. That does not make cancer a personal failure, but it does make preventive behaviors hard to ignore.<\/p>\n\n\n\n
Eating less<\/h2>\n\n\n\n
In the main interview, Garattini put his food philosophy in one blunt line: \u201cThe important thing is not so much when you eat, but how much you eat,\u201d he said. He also pointed to animal studies suggesting that reducing food intake by 30% can raise life expectancy by up to 20%.<\/p>\n\n\n\n![\"Dr.](\"https:\/\/okdiario.com\/metabolic\/en\/wp-content\/uploads\/2026\/06\/silvio-garattini-oncologist-longevity-habit.jpg\" "\\"\\"")
Oncologist Silvio Garattini, 97, emphasizes that longevity and cancer prevention rely on consistent daily habits like walking 3 miles and eating moderate portions. <\/figcaption><\/figure>\n\n\n\nThat claim needs a careful reading. Research in rhesus monkeys<\/a> has found that calorie restriction without malnutrition can delay aging-related disease, although results have not always been identical across trials, and humans are not lab animals.<\/p>\n\n\n\nSo, eating less is not the same as starving yourself or copying a fasting routine from the internet. For teenagers, pregnant people, people with diabetes, older adults at risk of frailty, or anyone with an eating disorder history, major diet changes should be discussed with a clinician.<\/p>\n\n\n\n
The 3-mile habit<\/h2>\n\n\n\n
Garattini\u2019s own routine is almost ordinary. In Corriere della Sera, he described walking about 3 miles a day<\/a>, eating little, avoiding tobacco, and giving up alcohol more recently. He still leaves room for pleasure, including dessert.<\/p>\n\n\n\nThat detail keeps the story grounded. The message is not a superhero workout or a perfect kitchen scale. It is closer to a brisk walk after a long day, fewer oversized portions, and stopping before feeling stuffed.<\/p>\n\n\n\n
The National Cancer Institute<\/a> says evidence linking higher physical activity with lower cancer risk comes mostly from long-term observation, but the pattern is strong for several cancers. Sitting all day may also carry risk. <\/p>\n\n\n\nAnyone who has spent hours in traffic, at a desk, or on a couch knows how easily stillness becomes the default.<\/p>\n\n\n\n
Tobacco and alcohol<\/h2>\n\n\n\n
Garattini\u2019s broader warning is not gentle. \u201cWe know perfectly well what we should do, but we do not do it,\u201d he says. Tobacco, alcohol, sedentary living, obesity, poor diet, and certain infections keep showing up because they are repeated exposures.<\/p>\n\n\n\n

Cheap calories are everywhere, alcohol is normalized in many social settings, and screen time makes hours disappear without much movement. That\u2019s why prevention can\u2019t be reduced to willpower alone.<\/p>\n\n\n\n
Still, daily choices are real. Quitting tobacco, drinking less or not at all, keeping up with vaccines and screening, walking more, and eating fewer ultra-processed foods are not flashy moves. They are the kind that change the long game.<\/p>\n\n\n\n
His medication warning<\/h2>\n\n\n\n
Garattini also criticizes what he sees as excessive medication. His personal rule is to take only what is strictly necessary, when it is necessary, and with caution. On cholesterol<\/a>, he has argued that changing \u201cnormal\u201d targets too aggressively can blur the line between medicine and market pressure.<\/p>\n\n\n\nThat critique should not be read as advice to stop prescribed drugs. <\/p>\n\n\n\n

Silvio Garattini advocates for a lifestyle centered on moderate eating, daily movement, and avoiding harmful habits to lower long-term health risks.<\/figcaption><\/figure>\n\n\n\nSmall changes that stick<\/h2>\n\n\n\n
One old saying captures his approach well: leave the table a little hungry. It sounds almost too simple, but in a world built around oversized servings and constant snacking, simple does not always mean easy.<\/p>\n\n\n\n
