More than four out of 10 cancer cases in U.S. adults ages 30 and older are attributable to potentially modifiable causes.1
Start making these 10 changes now to transform your general health for years to come:
Calculate your body mass index (BMI) to see if you’re at a normal weight. Even if you are, still watch your waistline and belly fat, as higher amounts of body fat are associated with increased risks of a number of cancers.2
Eat more fruits and vegetables, and less meat, starches, and desserts. Using smaller plates and measuring amounts while cooking are all handy ways to keep your excess intake down too.3
Exercise for 30 minutes a week. Break it up—15 minutes twice a week, or 10 minutes three times a week. As long as you’re getting physical activity—rather than, say, watching TV, browsing the web, or playing video games—you’ll get the same health benefits.3
Don’t exceed two alcoholic beverages a day if you’re a man or one beverage a day if you’re a woman.3
Smoking can cause cancer and then block your body from fighting it by changing or damaging a cell’s DNA and weakening the body’s immune system. While nine out of 10 deaths from lung cancer are caused by cigarette smoking or secondhand smoke exposure, smoking can also cause cancer of the blood; bladder; cervix; colon and rectum; esophagus; kidney and renal pelvis; larynx; liver; lungs, trachea, and bronchus; mouth and throat; pancreas; and stomach.6

Try to avoid lamb, beef, and pork, as they’ve been classified as “probably carcinogenic to humans” by the World Health Organization (WHO). Also avoid processed meats, which include hot dogs, ham, corned beef, beef jerky, and certain deli meats, as they’re classified as “carcinogenic to humans” that can increase cancer risk.4
90% of Americans consume too much salt.5 Substitute herbs and spices, ensuring you don’t consume more than 2,300 mg of sodium in a day. Check labels on “low-sodium” foods and condiments, as they may still contain a lot of salt.3
Try your best to meet your nutritional needs through diet alone, but if you feel strongly about adding supplements, talk to your doctor—as they aren’t recommended for cancer prevention.3
Limit the sugar in your daily caloric intake to 10% or less, avoid eating fast food, and refrain from drinking beverages that are processed or high in added sugar.3
Aim to eat at least five servings of fruits and vegetables daily; two plant-based foods out of every three servings you consume; and steamed, broiled, microwaved, sautéed, or baked foods vs. fried or cream sauce–covered foods.3
