The Mediterranean diet plan or the paleo is followed by millions of Americans, but some of them don't know the benefits of the popular diet, and don't even know if it's right for them. The food of our ancient ancestors is where the paleo, or paleolithic diet was based, whereas Mediterranean-style eating or diet will do fruits and vegetables, legumes and whole grains, and if in moderation it allows wine.

Joy Bauer, a nutrition expert, said on Wednesday, "When it comes to the Mediterranean diet, we're talking about eating primarily plant-based foods." "Using olive oil instead of butter, limiting red meat to a few times a month and eating fish and poultry weekly." Joy Bauer also stated, "The paleo diet is a bit more restrictive," "it wants you to eat all the lean, healthy proteins, but cuts out grains, beans, dairy, added sugars and processed foods."

The United States Department of Agriculture stated, that a person's healthy diet is low in saturated fats, cholesterol, salt and added sugars, thus, the Americans healthy diet is one that emphasizes fruits, vegetables, whole grains and low-fat dairy, and includes lean meats, poultry, fish, beans, eggs and nuts.

The  Cancer Society Research Centre researchers, found out that men with prostate cancer can benefit from a Mediterranean-style diet. The researchers study found that "olive oil, fruit and vegetables, legumes (pulses), whole-grains and poultry with some fish and seafood" will respond favorably to men with prostate cancer.

Dr. Karen Bishop of Auckland, New Zealand, stated, "We showed that dietary change to a Mediterranean-style diet is both achievable and beneficial for men with prostate cancer in New Zealand, albeit in a small and motivated group," Dr Bishop also said, "This is the first time such a study has been carried out in men with prostate cancer in New Zealand. This result adds weight to the notion that a low-inflammatory, high antioxidant diet may benefit men with prostate cancer."

Mediterranean diet can also reduce a person's risk of Dementia. A trained dietitian used a 137-item food questionnaire, to people with and without Mediterranean diet and the result is that the memory of the people with Mediterranean diet was preserved, and slightly improved 4 to 9 percent. And the people which adapt a non-Mediterranean diet have their memory function actually declined by 17 percent.
