A nurse is counseling a client about principles that promote weight loss. Which of the following statements by the client indicates an understanding of the teaching?

A. Limits red meat intake to two servings a month: Limiting red meat intake is a protective dietary behavior when it comes to cancer prevention. High consumption of red and processed meats has been linked to colorectal and other cancers. Two servings a month is relatively low and does not place the client at increased risk, but rather may help reduce cancer risk.
B. Eats six servings of whole grains daily: Whole grains contain dietary fiber, antioxidants, and phytochemicals that support digestive health and reduce inflammation, which may protect against certain cancers, particularly colorectal cancer. Eating six servings of whole grains daily is consistent with cancer-preventive nutritional guidelines.
C. Eats at least five servings of fruits and vegetables daily: Fruits and vegetables provide essential vitamins, minerals, fiber, and phytonutrients that have cancer-fighting properties. A daily intake of at least five servings supports immune function, cellular repair, and may reduce the risk of various types of cancer, including stomach and lung cancers.
D. Limits alcohol consumption to two drinks per day: Consuming up to two alcoholic drinks daily may still increase cancer risk, especially for breast, liver, esophageal, and colorectal cancers. The safest approach in cancer prevention is to avoid alcohol or limit it to no more than one drink per day for women.

A. Apples: Apples are naturally low in phenylalanine, the amino acid that clients with phenylketonuria (PKU) cannot properly metabolize. Fruits like apples are generally safe and are encouraged in a low-phenylalanine diet because they help meet nutritional needs without contributing excess protein or phenylalanine.
B. Milk: Milk is high in protein and contains significant amounts of phenylalanine, making it unsuitable for individuals with PKU. Consuming milk can lead to elevated phenylalanine levels, which are harmful to the developing fetus and can cause cognitive impairments and developmental delays. Pregnant women with PKU must strictly avoid high-protein foods such as milk.
C. Carrots: Carrots are low in protein and phenylalanine, making them a safe and beneficial food choice for clients with PKU. They provide important nutrients like beta-carotene and fiber without compromising phenylalanine restrictions. Including vegetables like carrots supports balanced nutrition during pregnancy.
D. Coffee: Coffee itself contains minimal or no phenylalanine unless additives such as milk or cream are used. While caffeine intake should be moderated during pregnancy, plain coffee does not significantly impact phenylalanine levels and is not a food that must be avoided specifically because of PKU.
