Nurse Josie should instruct the client to eat which of the following foods to obtain the best supply of Vitamin B12?
A. Dairy products
B. Vegetables
C. Grains
D. Broccoli
Correct Answer: A. Dairy products
Good sources of vitamin B12 are dairy products and meats. Among animal products, those from ruminants are particularly rich in vitamin B12, which is naturally synthesized by the ruminal microflora and transferred to milk. Dairy products retain, in general, a major part of the vitamin B12 naturally present in milk, some processing conditions may even add to the basal level by production of vitamin B12 from propionic bacteria in Swiss-type cheeses.
Option B: Vegetables are good sources of potassium, dietary fiber, folate, vitamin A, and vitamin C. Adding vegetables can help increase intake of fiber and potassium, which are important nutrients that many Americans do not get enough of in their diet.
Option C: Grains are important sources of complex carbohydrates, dietary fiber, thiamin, riboflavin, niacin, folate, iron, magnesium, and selenium. Consuming whole grains as part of a healthy diet may reduce the risk of heart disease. Consuming whole grain foods that contain fiber, as part of an overall healthy diet, can support healthy digestion.
Option D: Broccoli is rich in fiber, vitamin C, potassium, vitamin B6, and vitamin A. Broccoli is also packed with phytochemicals and antioxidants. Phytochemicals are chemicals in plants that are responsible for color, smell and flavor. Research shows that they have numerous healthful benefits, according to the American Institute for Cancer Research. Phytochemicals in broccoli are good for the immune system. They include glucobrassicin; carotenoids, such as zeaxanthin and beta-carotene; and kaempferol, a flavonoid.
