Climate and Seasons. Arizona's climate varies widely by altitude. Southern Arizona, including Phoenix and Tucson, has very hot summers and mild winters, with cooler summertime temperatures in the Chiricahua Mountains in the southeast corner of the state. Best times to visit are fall, late winter and early spring or higher elevations in summer. Northern Arizona, including Flagstaff, Sedona and the Grand Canyon, has four seasons but weather is mild enough to visit any time. Topography. Arizona covers 113,909 square miles, with about 350 square miles of water surface.
The staple food in different parts of the world is a function of weather patterns, local terrain, farming constraints, acquired tastes and ecosystems. For example, the main energy source staples in the average African diet are cereals (46 percent), roots and tubers (20 percent) and animal products (7 percent).
Fat, in addition, plays a vital role in the digestion of vitamins. Vitamins A, D, E, and K are fat soluble vitamins, meaning they need fat in order to be absorbed into the body. 3. Carbohydrates. Carbohydrates are the main energy source of the body. They are chains of small, simple sugars that are broken down and enter the body as glucose. Glucose is essential for the body, as it is the preferred source of energy in our brain, heart and central nervous system. For this reason, your diet should consist of at least 45 to 65 percent carbohydrates. Carbohydrates are found in many foods. However, you should stay away from sweet foods with excess sugar.
