Brushing Our Teeth with a Plastic Toothbrush with Petroleum-Based Bristles, Not Good


Brushing with a plastic toothbrush causes microplastic ingestion because the mechanical friction of brushing breaks down the petroleum-based bristles. Most of the time, the bristles are made of nylon or polyester. The friction, combined with our toothpaste's abrasives and our saliva, causes non-visible to our human eye...tiny fragments that sliver off into our mouths, which are then swallowed. We have all heard of microplastics getting onto our bodies and wreaking havoc with them. Yikes!!


Research indicates that an estimated 30 to 120 microplastic particles are released per brushing session. Unbelievable! 


Here is how the process works: 


Mechanical Breakdown: The bristles scrape against teeth and gums. This friction wears out the synthetic polymers, causing them to fragment into microscopic pieces. 


Chemical Exposure: The pH of our saliva and the chemical compounds in our toothpaste further weaken the plastic fibers over time. 


Ingestion: These broken fibers and fragments mix with our toothpaste and saliva. While some are spit out with the foam, a big portion is inevitably swallowed along with the toothpaste residue. 


While dental experts say that regular brushing is still essential for oral health, ongoing studies are tracking how the ingested plastics might trigger inflammatory responses and even disrupt the necessary bacterial balance in our guts and mouths.


Scientific proof is available at: https://pubmed.ncbi.nlm.nih.gov/37689132, We found on Amazon a great choice: Sea Turtle Plant-Based Bristles, Bamboo Toothbrushes, Soft Natural Toothbrush for Adults (4 Pack) for just $7.99. The bristles are made from Nylon 1010, a 100% plant-based and bio-based polymer extracted directly from castor bean oil. They are an eco-friendly, renewable, and petroleum-free alternative to traditional plastic nylon bristles.

Our family is using them. Fantastic!

Feel Young: Increase your Bone Density, Sweetheart!

Image
  You Got This! 💜 Bone density naturally declines with age, but the right nutrition and exercise can slow or even reverse that process. Here’s what really helps: Eat for Bone Strength 1. Calcium-rich foods: Dairy products, fortified plant milks, leafy greens, almonds , and canned fish with bones (like sardines or salmon). 2. Vitamin D: Supports calcium absorption. Get it from sunlight, fortified foods, or supplements if needed. 3. Protein: Essential for bone structure. Include lean meats, eggs, beans with rice, and tofu . 4. Magnesium and Vitamin K: Found in nuts, seeds, whole grains, and green vegetables —these nutrients help regulate bone metabolism. Exercise for Bone Health 1. Weight-bearing workouts: Walking, jogging, dancing, climbing stairs, or hiking stimulate bone growth. 2. Resistance training: Lifting weights or using resistance bands strengthens both muscles and bones. 3. Balance and flexibility: Yoga or tai chi reduce fall risk and support joint stability. Consi...

The "Calorie Ceiling" Shock: Why Science Says You Can't Outrun Your Diet in 2026

Image
If you have ever felt like you were sweating away hours at the gym with zero weight loss to show for it, new research from early 2026 has finally vindicated you. A groundbreaking update to the "Constrained Energy Expenditure" model suggests that for many people, the body actively fights to keep daily calorie burn stable, regardless of how much you exercise. Unlike the old "machine" model—where more movement equals more fuel burned—these new findings indicate our metabolism functions more like a budget. When you spend too much energy running or lifting, your body doesn't necessarily pull from your fat reserves; instead, it aggressively "refunds" that energy by dialing down other invisible systems, such as immune function, inflammation responses, and even fidgeting, effectively capping your total daily burn. This "shocking but true" discovery upends the decades-old dogma of "calories in, calories out." It explains why chronic cardi...

Whodathunk that Tart Cherry Juice Has So Much Power to Heal the Human Body?!

Image
Might want to replace one cup of your of coffee for a glass of tart cherry juice. You will love you for it! Tart cherry juice, particularly from Montmorency cherries, is quite effective for reducing inflammation, relieving joint pain/arthritis, speeding up exercise recovery, and improving sleep quality even due to its high concentration of anthocyanins and natural melatonin. Now, why did TropicFeather's Jill and I, Suzanne, come up with this as a topic for our health blog? Suzanne has suffered from a pinched nerve for 5 1/2 months now. She received physical therapy twice a week that only relieved the pain for a few hours each time. She's tried all kinds of things, but guess what seems to be working all of a sudden? Tart cherry juice! She's drinking about 8- 12 ounces per day for the last 3 days, and the pain has lessened quite a bit. The tingling and numbing of her left hand and forearm still acts when she holds something heavy in the hand or leans over to pick something up...
