Avoid sugary drinks and limit consumption of energy-dense foods. It's not that these directly cause cancer, but they could blow your calorie limit if you often overindulge. It is suggested to filling up on fruits, vegetables and whole grains.
Eat more of a variety of vegetables, fruits, whole grains and legumes such as beans. Go for a variety of colors (like deep greens of spinach, deep blues of blueberries, whites of onions and garlic, and so on). Most people are stuck in a habit of eating the same vegetables over and over.
Always avoid alcoholic drinks. The pros and cons of drinking is something that women may particularly need to consider, weighing the heart benefits and increased breast cancer risk.
Limit red meats (beef, lamb) and avoid processed meats. Limit red meats to 18 ounces per week. It is suggested to use chicken, seafood or legumes in place of red meat. But it is not that never eat red meat, just do so in moderation.
Limit consumption of salty foods and foods processed with sodium. Don't go over 2,400 milligrams per day, and use herbs and spices instead. Processed foods account for most sodium intake nowadays, not salt you add when cooking or eating.
Don't use supplements to protect against cancer, It's not that supplements are bad, they may be "valuable" apart from cancer prevention, but there isn't evidence that they protect against cancer, except for vitamin D.
It's best for mothers to breastfeed babies exclusively for up to six months and then add other foods and liquids. Doctors could encourage this more.
