True: When tomatoes are heated -- like in sauce or the processing of ketchup -- the benefits of lycopene are enhanced because it's more easily absorbed by the body than when in raw tomatoes. Studies show that the body uses lycopene for protection against breast cancer, prostate cancer and heart disease.
The benefits of grapes come from a valuable nutrient called grapetine, which is necessary to keep the squishy substance in your eyeballs replenished.
False: Grapes are full of beneficial nutrients and antioxidants; however, grapetine is not one of them. In fact, it's not real at all. A study from the Journal of Nutrition shows that eating fresh grapes may prevent the accumulation of harmful oxidized cholesterol and those naturally occurring antioxidants in fresh grapes, known as polyphenols, are believed to be responsible for this positive effect.
One polyphenol in particular, resveratrol, has demonstrated its ability to help protect against arterial wall damage caused by "bad" (LDL) cholesterol. Another polyphenol, tannin, was shown in a Canadian study to eliminate disease-forming viruses and tumors. Grapes also include high levels of caffeic acid, which is a strong cancer-fighting agent.
Mushrooms are good for more than just making tie-dye shirts groovy.
True: Mushrooms are an underappreciated, low-calorie food rich in nutrients. Mushrooms surpass all other items in the produce category in selenium, which was shown in one study to decrease prostate cancer by 60 percent. Also, mushrooms are an excellent source of three essential B-vitamins: riboflavin, niacin and pantothenic acid.
Additionally, mushrooms are an under-recognized source of potassium, which has been shown to help regulate blood pressure, keep the right balance of water in fat and muscle tissues, and ensure the proper functioning of cells. One 3-ounce portabella mushroom cap provides more potassium than an orange or even a banana.

The banana is an appealing fruit, packed with nutrients, that won't cause you to slip off your diet. True: Bananas are a great source of vitamin C, potassium and dietary fiber. Potassium is an essential mineral for protein synthesis and the building of muscle because it stimulates nerve impulses for muscle contraction. Since bananas are sodium-free and very rich in potassium, they can be eaten as part of a diet to reduce the risk of high blood pressure. Plus, bananas contain a good supply of vitamin B6, which is significant in the production of antibodies in the immune system, as well as helping in protein metabolism, red-blood-cell formation and functioning of the central nervous system. Bananas have no fat, cholesterol or sodium.
