Study finds strong evidence linking cell phone radiation to cancer
June, 2025
A World Health Organization-backed study determined with a high level of certainty that there are links between cell phone radiation and two types of cancer in laboratory animals— malignant nerve tumors in the heart and gliomas (a type of brain cancer). This is a significant development because, as Dr. Devra Davis, founder of the Environmental Health Trust, points out, “Every agent that causes cancer in humans will produce it in laboratory animals when adequately tested.”
Results of the study prompted this swift response from the International Commission on the Biological Effects of Electromagnetic Fields: “Given this high level of certainty, government policymakers worldwide should immediately move to revise their radiation exposure limits to protect public health and the environment.”
In the meantime, it’s wise to take simple precautions to reduce exposure.
· Keep the phone away from your head and body.
· Avoid carrying your cell phone on your body at all times.
· Avoid using your cell phone when the signal is weak or inside metal vehicles and elevators.
· Use airplane mode and turn antennas off when not in use.
· Children should only use cell phones for emergencies.
· Do not charge a cell phone or sleep with it near your bed.
· Use a corded landline at home.
· Minimize talk time on your cell phone.
· Connect your cell phone to the internet without radiation by using an ethernet cord.

Why I’m cooking with olive oil
By Linda Mason Hunter
June, 2025
Seed oils have been much in the news lately, ever since Robert F. Kennedy, Jr., the current Secretary of U.S. Health and Human Services, described them as “poison.” We’re talking about cooking oils that come from vegetable seeds, like corn, canola, cottonseed, sunflower, safflower, and grapeseed. Many wellness influencers and restaurant chains say they are transitioning away from seed oils in favor of animal fats, chiefly beef tallow and butter.
Wait, what? Are nutritionists now saying animal fat is good for you? I thought it was associated with high cholesterol, heart disease, and cancer. How can plant-based seed oils be worse?
Some studies link seed oils with body-wide inflammation, which accelerates all kinds of disease. At the end of the day, good health is all about reducing inflammation.
However, much of the concern centers on the fact that, due to their high linoleic acid content, seed oils have an over-abundance of omega-6 fatty acids, whereas a balanced ratio of omega-3 and omega-6 is best for health. There’s already an imbalance in the typical Western diet due to widely available seed oils used in fried fast foods and ultraprocessed foods, which comprise roughly 10% of the U.S. food supply.
So, should you cut out seed oil altogether? The answer depends on what you replace it with. Animal fats, like beef tallow and butter, are high in saturated fat which is bad for cardiovascular health. Best to switch to olive oil or avocado oil which contain omega-3 fatty acids, thus lowering the risk of cardiovascular disease and dementia. Extra virgin olive oil has an added bonus: It’s minimally processed, thus retaining beneficial nutrients that get stripped away in the production of most other oils.
After reviewing the pros and cons, I’ve decided extra-virgin olive oil is the healthier choice. That is what I am doing, while also avoiding ultra-processed foods altogether.

How to dispose of plastic
Have you ever gotten to the end of, say, a jar of peanut butter and wondered if it should go in the trash or recycling? Is it worth rinsing out? And where will it actually end up? Those are questions I’ve been wrestling with these days.
Fortunately, I found answers on the NPR radio show “Science Friday,” where Alexander Clapp, journalist and author of Waste Wars: The Wild Afterlife of Your Trash,” offered the best argument for rational disposal.
Don’t think that recycling plastic is the answer. Recycling doesn’t work, and never will, he says. It’s not efficient. Each of the thousands of different kinds of plastic must be sorted according to composition and characteristics, making it impossible to sort the trillions of pieces of plastic into separate types of processing.
Secondly: Recycling is expensive. It’s always cheaper to produce new plastic than to attempt to resurrect old plastic.
Third: Recycling plastic is often dangerous. You can’t incinerate it without introducing a toxic mess of particulates into our soil, air, and water, eventually ending up in our food, causing tiny microplastics to accumulate in our bodies.
And last, but certainly not least, plastic is made from fossil fuels, the major cause of climate change.
So, what’s the best way to dispose of plastic? The answer is easy. Don’t Buy It In the First Place! But that’s virtually impossible in 21st century America. The next best answer? Throw it in the trash. Yes, you heard me. Landfills these days are lined, preventing most toxins and pollutants from escaping into the soil. Until a better, more sustainable solution appears, throwing used plastic in the trash is the best solution we’ve got.

Blueberries are wonderful for health and well-being
A while ago I saw a comment on Facebook that I believe is wrong and must be righted. The comment was that all antioxidants cause cancer, especially blueberries. Not so. Blueberries are packed with antioxidants, which gives them powerful protection against aging, heart disease, cancer, and brain decline by fighting oxidative stress. Wild blueberries contain even higher levels of antioxidants.
There are concerns that antioxidants from supplements may have some risks associated with them, risks that antioxidants from foods don’t have. Especially the really high dose supplements. I’ve always thought it comes back to the Whole Foods theory, better to eat the whole food then take isolated nutrients. Also, during chemo and radiation treatment for cancer, patients are advised against eating blueberries because antioxidants can interfere with the treatment which relies on oxidative stress to kill cancer cells.
Blueberries are one of the best foods for anti-angiogenesis, meaning preventing cancer from forming its own vessels. In this era of high inflammation and skyrocketing cancer diagnoses, eating blueberries often is an excellent idea. Best to buy them organic.

Just a little bit…
