Their advice comes amid warnings that rates of the deadly brain disease will triple in the next 40 years unless preventative measures are taken.
Increasing scientific evidence has shown that following a specific diet and exercise routine can reduce the risk of developing dementia by more than half.
Leading US researcher Dr Neal Barnard launched the seven guidelines at the International Conference on Nutrition and the Brain in Washington.
Taking regular exercise, eating plenty of vegetables, beans and pulses and limiting bad fats are all key.
The guidance says vegetables, fruits, legumes - beans, peas, and lentils - and whole grains should be daily staples along with a handful of nuts or seeds for vitamin E.
People are also encouraged to ensure they get vitamin B12 daily either from milk and eggs or a supplement providing at least the recommended daily allowance.
Dr Barnard suggests avoiding the use of cookware, antacids, baking powder, or other products that may add aluminum to the diet, although its role remains unclear.
Finally, he advises regular aerobic exercise, equivalent to 40 minutes of brisk walking three times a week.
