More people are developing Alzheimer's disease, dementia and memory loss than ever before. But the newest scientific breakthroughs, for the first time, may turn the tide, says Dr. Mehmet Oz. He revealed the latest ways to reduce your risk of developing Alzheimer's disease and strengthen your brain on his April 1 talk show.

You may not even think about pesticides like DDT when you buy food in the grocery store. But Dr. Oz's guest expert Cynthia Green warned that patients with Alzheimer's disease were discovered to have four times as much DDT in their bodies in a recent study. She's the author of "Brainpower Game Plan: Sharpen Your Memory, Improve Your Concentration, and Age-Proof Your Mind in Just 4 Weeks" (click for details) and "Your Best Brain Ever: A Complete Guide and Workout."

A memory loss expert, Cynthia recommends being cautious about foods imported from other countries, such as spinach, grapes and strawberries. Consider buying local at a Farmer's Market or growing your own pesticide-free food.

In recent years, some controversy has existed about whether fish oil supplements are beneficial in battling dementia and Alzheimer's. Cynthia cites studies showing a connection between shrinking brain tissue and levels of omega-3s. She recommends eating three servings a week of cold water fish such as salmon or take 1,000 mgs of fish oil supplements daily.

Here's a new term to keep in mind when you want to lower your risk of Alzheimer's disease: Pulse pressure. You can determine your pulse pressure by subtracting your blood pressure numbers. Example: If you have a blood pressure of 130 over 90, your pulse pressure is 40. If your pressure is higher than 60, Dr. Oz is concerned because that puts you at a higher risk of Alzheimer's disease. Talk with your doctor about options for reducing your blood pressure.
