New Perspectives on Blue and Purple Colored Foods

It is June and blueberries and blackberries are in season. We look forward to the taste of these delicious berries every summer. But we also need to appreciate their healing benefits.

Blueberries have been shown to decrease free radical damage to DNA by 18% within 1 hour versus a control group. Any time we can decrease DNA damage, we are doing something good for our bodies. This colored food is beneficial for brain health. It may help with cognition and memory.

But there are many other blue or purple foods that we can enjoy and benefit by eating.

  • Asparagus, the purple variety
  • Beets
  • Bell peppers, the purple varieties
  • Berries-black, blue, Boysen, huckle, marion
  • Cabbage, the purple variety
  • Carrots, yes, purple carrots are widely available
  • Corn
  • Currants
  • Eggplant
  • Cauliflower
  • Figs
  • Grapes
  • Kale, lacinato or dinosaur tongue variety
  • Onions
  • Plums
  • Potatoes, the purple varieties
  • Prunes
  • Raisins
  • Rice, like the Forbidden variety
  • Tomatoes, the Indigo varieties

Purple and blue foods may be anti-cancer foods. They help to minimize how cancer-causing compounds are triggered as well as provide some help with detoxification. They may inhibit DNA damage. They may inhibit the invasiveness of cancer cells and their spread.

Resveratrol, the compound found in red wine and other red fruit, is an anthocyanin which may help slow cell aging.  Who would not like to have young cells?

Anthocyanins may help keep the heart healthy, control blood pressure, reduce obesity, improve cholesterol levels, boost immunity, help prevent cancer and inhibit tumor growth, and improve memory.

CAFOs and Your Healthy Eating

This is how we picture beef cattle; the reality is far different, and probably unhealthy.

Concentrated Animal Feed Operations (CAFO) is an industrial agricultural system for raising livestock. These operations started in the 1970s. CAFOs place thousands of animals in a confined area, with large feedlots for cattle, large houses for poultry and pork, and confined netted enclosures for fish. CAFOs pose several threats to you directly and the environment. Let’s start with beef.

In large-scale beef production, the cattle are fed corn and soy, an unnatural diet for them. Cattle should be grazing on grass in pastures. Corn is omega-6 (inflammatory) and grass is omega-3 (anti-inflammatory). Grass–fed and finished beef is healthier for you and more humane for the animal. Cows are also given bovine growth hormone to add weight quickly in order to get to market more quickly. A shorter time from birth to slaughter means more money. You probably don’t need a dose of bovine growth hormone to help you bulk up.

These same types of scenarios can be seen with pigs, chickens, and fish. We would like the animals we raise to live a natural and healthy life eating what nature intended. 

Antibiotic used in livestock accounts for 80% of antibiotic use in the U.S. An animal raised in a CAFO needs antibiotics in order to stay alive in this unhealthy environment.  Antibiotics used in this way support the emergence of superbugs. Superbugs may be antibiotic resistant. You may have heard of the growing concern in medicine over drug resistant bacterial infections. The medical community fears we may one day soon have many drug resistant infections with no antibiotic solutions. This scenario would take our world back to days before antibiotics, like penicillin.

Sweden became concerned about the increase in drug resistant pneumonia infections in the 1990s. To counter this increase, they severely restricted antibiotic use in their animal husbandry practices. By also using antibiotics only for bacterial infections in humans, the Swedes saw that antibiotics used for people drop by 43% – 74%, depending on the age of the population being studied. Would you like to live where infections were down?

The animal urine and feces generated by the animals in CAFOs is placed in liquid manure lagoons which may leak into underground water polluting drinking supplies and the natural ecosystem.

CAFOs also account for 18% of human greenhouse gas production. Greenhouse gas helps to fuel climate change that makes it harder for all the animals, plants and humans to thrive, and some even to survive. We depend on the diversity of our home, Earth, for our health and lives.

New Perspectives on Food Choices and the Environment

Wednesday, April 22nd, is Earth Day, and 2020 is the 50th anniversary. We have made some progress in saving the Earth, our home.

But there is much room for improvement. To celebrate the anniversary of Earth Day, the April 2020 issue of National Geographic highlights How We Lost the Planet and How We Saved the Planet, as seen in the covers of the magazine.

Did you know that your food choices are a powerful way to help the planet sustain us? To eliminate greenhouse gases would be a giant step forward, but what about removing CO2 from the atmosphere? There is a movement working on remove CO2 and it is called Project Drawdown. You can find out more at:

Food touches everything in our world. Food influences our environment. Local sustainably raised food requires healthy soils. Sustainably–raised produce uses less, or better, no pesticides or herbicides. This may allow farm workers to experience less disease due to lower exposure to these harsh chemicals. Court cases are now being won by farm workers harmed by pesticide exposure.

Our bodies need the most nutritious food we can give them.

Food produced with pesticides and herbicides may negatively impact bees, insects, the microbial diversity of the soils, as well as wildlife and ourselves. Sustainably grown produce may be more nutritious because the produce has less pesticide residue. In addition, the soils are healthier fewer beneficial insects and microbes are killed by pesticides.

Locally grown, sustainably–raised produce helps your community. The nearby farms can sustain themselves financially while providing food that is fresher and not grown for shipping, but for taste. Fresher equals more nutritious food since it may be eaten closer to the time it was picked.  Locally grown means lower transportation costs in getting your food to you.

Victory Gardens planted during World War II made up 40% of our food needs. Victory Gardens were instituted not only to help feed people, but also to free up transportation and labor for the war effort. We could learn from those times and reap the benefits of fresher nutritious food grown closer to home. This may be important as we learn how supply chains can be disrupted. COVID-19 gives us the opportunity to appreciate how we can help to make ourselves more resilient going forward.

Our bodies need the most nutritious food we can give them. The building blocks of optimal nutrition need to be present to give us the best possible health. Food can indeed be our most powerful medicine.
