Research methods in the sociology of the family can be broken down to three major approaches, each with its own strengths and weaknesses; which need be employed in a study, then, relies largely on the subject of, and questions posed by, the research. One approach is survey research of contemporary families.
Potassium pills only provide potassium, but bananas also provide a variety of other nutrients. Each medium banana contains 12 percent of the daily value for fiber, 17 percent of the DV for vitamin C, 22 percent of the DV for vitamin B-6 and 16 percent of the DV for manganese.
Bananas are a great dietary source of potassium. One medium-sized banana (118 grams) contains 9% of the RDI. A potassium-rich diet can help lower blood pressure, and people who eat plenty of potassium have up to a 27% lower risk of heart disease (22, 23, 24, 25). Furthermore, bananas contain a decent amount of magnesium, which is also important for heart health (26, 27). Bottom Line: Bananas are a good dietary source of potassium and magnesium, two nutrients that are essential for heart health.
