After a diagnosis of breast cancer, women tend to re-evaluate their nutrition and health practices. Many wonder what caused this cancer to occur and what lifestyle changes they should be making. Most women believe they must make significant dietary changes to ensure good outcomes following breast cancer treatment. However, a healthy diet is only one of several factors that can affect the immune system; exercise and stress management are just as important in improving your overall health and well being.

Guidelines for Healthy Eating
There are no food or dietary supplements that will act as “magic bullets” to prevent breast cancer from returning. National Cancer Institute guidelines for cancer prevention can be used to decrease the chance of a breast cancer recurrence. These guidelines include:
- Increase intake of fruits, vegetables and whole grains
- Decrease fat intake to < 30 percent of calories
- Minimize intake of cured, pickled and smoked foods
- Achieve and maintain a healthy weight
- Alcohol consumption should be done in moderation, if at all
MYTH: I should eat an organic diet to reduce my chances of a recurrence. Get the facts.
Fruits, vegetables and whole grains are known to contain phytochemicals with antioxidant, antiestrogen and chemopreventive properties that may prevent cancer. We recommend five or more servings of fruit and vegetables daily. Cruciferous vegetables (broccoli, cauliflower, kale, cabbage and brussels sprouts) are especially rich in phytochemicals. Extensive research has been conducted at Johns Hopkins Medicine regarding the nutritional value of broccoli sprouts.
Whole grains are unprocessed foods that are high in complex carbohydrates, fiber, vitamins, minerals and phytochemicals. High fiber intakes may have a positive benefit by altering hormonal actions of breast cancer and other hormonal-dependent cancers. Daily fiber intake should be 25 to 35 grams of insoluble and soluble fiber.

Controversy exists on the role of dietary fat on the promotion of breast cancer. Some animal studies and epidemiological data have suggested that the type of fat consumed may initiate the development of breast cancer. We recommend that you:
- Limit the intake of highly saturated foods such as beef, lamb, organ meats, cheeses, cream, butter, ice cream
- Decrease food containing trans fatty acids, such as commercially prepared baked goods, crackers and margarine
- Increase your intake of poultry, fish and vegetarian proteins (legumes and lentils). Increasing your intake of fish to 3 times per week will increase omega-3-polyunsaturated fat intake. Research has suggested that these fatty acids may inhibit the growth of breast tumors.
How to calculate your ideal body weight and daily fat and calorie needs:
1. Calculate your ideal body weight (IBW) using your height in inches.
- The first 5 feet of your height = 100 pounds
- Add 5 pounds for each additional inch in height
For example: A person is 5 foot, 4 1/2 inches tall
- The first 5 feet = 100 pounds
- To determine the rest of the ideal body weight, multiply 4.5 inches by 5 pounds = 22.5 pounds
- A person 5 foot 4 1/2 inches tall has an ideal body weight of 122.5 pounds: 100 + (4.5 x 5) = 122.5 pounds IBW
2. Account for your frame size:
- Small frame: Subtract 10 percent from IBW = 110.25 pounds
- Medium frame: Use IBW formula only = 122.5 pounds
- Large frame: Add 10 percent to IBW = 134.75 pounds
3. Calculate your recommended daily calorie intake:
- Your IBW x 10 x activity factor = your daily calorie intake
- Sedentary = 1.2
- Moderate = 1.4
- Active = 1.6
4. Calculate your daily fat needs
- Using 30 percent of calories coming from fat: Multiply your calculated number of calories x 0.3 = percentage calories coming from fat
- Divide this answer by 9 = grams of fat needed per day
Obese women have higher levels of circulating estrogen than women at their ideal body weight. Many studies have demonstrated an association between body mass size and breast cancer in postmenopausal women. We recommend weight reduction through a healthy diet (five small meals; more fruits, vegetables and grains; less meat, dairy, fats and sugar) and exercise. We provide weight loss counseling that focuses on healthy eating tips and behavior modifications that will provide long term results.
Several studies have shown an association between alcohol consumption and breast cancer. Alcohol’s role in the development of breast cancer remains unclear. Dietary guidelines suggest that a woman consume no more than one drink per day. Women diagnosed with breast cancer may want to consider avoiding alcohol.
