Although cashews are one of the lowest-fiber nuts, they are packed with vitamins, minerals and antioxidants. These include vitamins E, K, and B6, along with minerals like copper, phosphorus, zinc, magnesium, iron, and selenium, all of which are important for maintaining good bodily function.
The best times to visit the Grand Canyon are March through May and September through November when daytime temperatures begin to cool and the crowds begin to thin. If you decide to visit during the summer (the park's peak season), be prepared for hordes of tourists and very limited lodging availability.
Give some thought to the time of day you want to photograph. According to a number of websites I read, the best times to photograph Horseshoe Bend are between 1pm and 3pm. The sunlight illuminates even the deepest parts of the canyon at that time. To see photographs of the bend at all hours of the day, reference this site.
