Foods That Prevent Disease
In the past few years, researchers have studied whether eating certain foods actually prevents disease. Scientists have begun to identify thousands of natural chemicals in foods that seem to have preventative powers. These aren’t just vitamins and minerals, they are phytochemicals.
Below are 6 foods that pack a nutritional punch. When used correctly they may have the power to prevent all kinds of serious ailments, including heart disease, diabetes and even cancer.
1. Fiber: Fiber helps to lower cholesterol, reducing risk factors for cardiovascular disease. Researchers at the University of California have said that fiber also reduces the risk factors for colon cancer and breast cancer. Fiber also helps control blood sugar levels, which is important for diabetics. Lastly, diets high in fiber help to keep you feeling full on few calories which will lead to weight loss.
2. Tomatoes: Tomatoes are high in lycopene- which is one of the most powerful antioxidants. Lycopene mops up free radicals thus reducing the risk for prostate cancer. Lycopene is best released from cooking tomatoes, so ketchup and tomato sauces are great sources. Tomatoes are also a great source of vitamin C.
3. Salmon: Salmon has lots of omega- 3 fatty acids which help the heart. Omega- 3s prevent platelets in the blood from clumping together and sticking to arterial walls in the form of plaque. They also drive down triglycerides and LDL cholesterol. Researchers suspect that omega- 3’s may block the production of inflammatory substances linked to arthritis and lupus and may even help fight against Alzheimer’s. That’s because omega 3’s interact with the fatty layers that surround brain cells and may help protect them.
4. Spinach: This vegetable is oaded with iron and folate. Folate lowers blood levels of homocysteine, an amino acid that irritates blood vessels and is linked to heart disease. Spinach also contains two phytochemicals that ward off macular degeneration, a leading cause of blindness. One cup has 41 calories, which means you don’t have to worry about excess calories.
5. Blueberries: Out of all fruits and vegetables blueberries have the most antioxidants per serving. Blueberries contain a phytochemical called anthocyanins that reduce risk factors for cancer and cardiovascular disease and may boost brain power as well. In a recent study, rats were fed blueberry extract for 9 weeks. Those that were fed the extract performed better as tasks such as navigating mazes and memory tests. Another blueberry benefit, like cranberries, they seem to fight urinary tract infections.
6. Pistachios: They are loaded with fat and can be salty but these filling little snack foods are nutritional powerhouses. Nuts are high in monounsaturated and polyunsaturated fats, which help to lower triglycerides and LDL cholesterol (bad cholesterol) while raising HDL levels(good cholesterol), thus reducing the risk factors for heart disease. Pistachios are also a good source of Vitamin E which is a potent antioxidant that may help ward off cancer. The downside? At about 160 calories per ounce, they are a sure ticket to the fat farm. Eat them by the handful, not bowlful.

Thank you for your comments on these “power house” foods. I think that lack of nutritional education is a leading cause of the obesity in this country.

This article was quite interesting – particularly in regard to the effect that Omega-3’s may have on Alzheimer’s.
Ongoing research and clinical trials that test potential new treatments are the best chance we have for fighting the disease.
I’m not surprised to see salmon, though I’m surprised that there is no mention of cancer causing chemicals found in the fat cells of most fish and no mention of the dangers of eating putrid-oil-fried salmon, which is the most common form at inexpensive restaurants.
I’m quite surprised to see pistachios, as I’ve never seen that make a top health foods list before. Walnuts can be eaten as they come and provide better fat ratios, generally at a more affordable price. Even almonds, pecans, or cashews would seem more likely recommendations.
Whole grains or seeds should be on the list somewhere, perhaps in place of #1?
“so ketchup and tomato sauces are great sources” – when made at home. Commercial products contain high amounts of sodium and HFCS. Bad choices for people.
“Out of all fruits and vegetables blueberries have the most antioxidants per serving.” – While awesome, they don’t have the most antioxidants per serving when grown on a commercial scale. Plus Acai berries knock them out of the park.
“At about 160 calories per ounce, they are a sure ticket to the fat farm. Eat them by the handful, not bowlful.” – Another fallacy. Fat doesn’t cause people to get fat, long term overeating of high sugar carbohydrates such as white bread, candy, soda…etc does. Don’t feed people this B.S. Remember the consumer is smarter than you think.
Don’t forget your spices. Curcumin (tumeric) is a cancer fighter. In studies it has been shown to kill cancer cells and it blocks Alzheimer’s pathogenesis. Also oregano has 30 to 20 times more antioxidant activity than any other herb, more than many fruits and vegetables.
