As a cereal grain, rice is the most widely consumed staple food for a large part of the world's human population. It is the grain with the second-highest worldwide production, after corn.
Rice is also the perfect low cost food with an extremely high nutritional value; and it can be even richer when combined with other foods such as beans.
It is the perfect accompaniment to beans because together they form a complete protein. This means that the two contain all of the amino acids that a person needs.
In fact, beans and rice combined have 419 calories, 81.5 g of total carbohydrates and only 1.5 g of total fat.
One serving provides 27 percent of the recommended daily value (DV) for carbohydrates (based on a daily diet of 2,000 calories). White rice has a medium impact on blood sugar (glycemic index of 58), but that's balanced against the low impact of kidney beans (glycemic index of 52 for canned and 34 for fresh).
The total fat includes only 0.2 g of saturated fat and a good amount of heart-healthy fatty acids. Beans and rice have 0.33 g of omega-3 fatty acids (20.6 percent of the recommended intake for men and 30 percent for women) and 0.31 g of omega-6 fatty acids (1.8 percent of daily intake for men and 2.6 percent for women).
