Crazy as it sounds, what you eat has a direct effect on your foot health. For example, a sugar-filled diet can cause inflammation that irritates existing foot problems; a diet rich in red meat and alcohol can lead to gout, a type of arthritis that affects the big toe; and a poor diet high in sugar, fat and refined starches can lead to diabetes, a condition that causes circulation issues, foot numbness and other severe foot problems that may require amputation. Conversely, a diet rich in fruits, vegetables, whole grains, and healthy fats keeps the structure of your feet strong, your foot skin soft and the rest of your body happy and healthy.
