Another way of maintaining an appropriate weight is to eat a balanced diet. The nutrients may also help prevent varicose veins. For example, vitamin C and protein are both components of the production of collagen. Collagen, while a significant factor in anti-aging products, is also one part of the development of veins and valves. If you have enough collagen in your veins and valves and in good shape, you are more likely to be resilient to varicose veins.
While standing for too long can be an issue, so can sitting. Some experts theorize that even sitting for extended periods can contribute to the development of varicose veins. The theory is that the bending of knees and hips will slow the return of blood to the heart. So, it is important to routinely move the legs during any long car ride, plane ride, or sitting at a desk.
