I think what you are asking about are really several diets, all based on that idea you have heard forever--eat a lot of fruits and vegetables. The reason that fruits and vegetables are brightly colored is that they contain a lot of vitamins, minerals, and phytochemicals. This is also the reason they are healthy things to eat--they are loaded with things that help your body to function well. So the theory goes that it is healthy to eat a lot of foods that are naturally brightly colored. If you have ever seen "You Are What You Eat" on the BBC, this is a point that Gillian MacKeith makes every episode. She lays out a week's worth of what a person has eaten that has helped them become overweight and unhealthy, and it is largely a table of beige and brown food--fried foods, soft drinks, burgers, french fries. The table of food she has them switch to has a multitude of colors, because it is mostly fruits, veggies, and grains.
Any food that is highly colored, can be consumed. The author refers, of course, to the tomatoes intense red colored, not red meat. The basic idea is to eat as many fruits and vegetables.
They are permitted:
- chicken white meat - Egg
- Fruits and vegetables
- Whole grain
- Popcorn (prepared in air)
- Olive oil or avocado.
This diet is based on the principle that food colors signify not only that the food looks good, but that the nutrients present different colors. The more intense a certain color of a food, the more content in certain nutrients is higher .
Basic principles are:
- Red: these foods contain Lycopene, which reduces the risk of cancer, examples of foods that contain it: tomatoes, watermelon, red grapefruit; - Dark red, purple: grapes, red wine, strawberries, blueberries and red apples;
- Orange: foods containing alpha and beta-carotene, which facilitate intercellular communication and slow the progression of cancer, examples: carrots, mango juice, sweet potatoes; - Orange / yellow: These foods contain vitamin C which protect cells and one of the many carotenoids, which Heber recommend them, examples: oranges, tangerines, papaya and nectarines
- Yellow-green: they are rich in carotenoids such as Lutein and Zeaxanthin, which contributes to eye health; examples: spinach and other greens, yellow corn, green peas and avocado - Green: foods containing isothiocyanate which stimulates liver cells to synthesize certain ingredients that fight cancer, caused by chemicals, examples: broccoli, sprouts Burxelles, bok choy and kale (in the mustard) - White / Green: These foods contain flavonoids that protect cell membranes, examples: garlic, onion, celery, white wine, endive and chives. Note that: It is harmful to eat too much of anything, even colored fruit. Herber prohibits the consumption of food with butter or margarine, preferring moderate amounts of olive oil or avocado. Those who are frightened when they hear that it has to eat from 5 to 9 servings of fruits and vegetables a day should start gradually. You can add some bananas and strawberries to cereal when eating in the morning. At lunch we can choose an intensely colorful salad as a additional portion in place of potatoes or pasta.
They are prohibited:
-Meat high in fat content
- Whole eggs
- Butter and margarine
- Farmed salmon.
