Originating in the Orient, soybeans have been around for over 3,000 years. These nutritional legumes contain a delicious, mild nutty flavor. Mainly green in color, soybeans can also be yellow, black, or brown. Today, the United States produces half of the world’s soybeans. Studies have proven these legumes help lower blood pressure and cholesterol in men, and are an excellent source for preventing high blood sugar levels in diabetics. It’s no wonder why soybeans are becoming a common snack choice. These legumes are packed with protein and other vitamins and minerals.
