Approximately 60% of the caffeine consumed in America is not natural caffeine from coffee beans or tea plants. It is synthesized in a laboratory. Companies like Red Bull, Coca-Cola, and Pepsi utilize synthetic caffeine in their drinks to give them the extra energy kick. Emerging research indicates that synthetic caffeine may accelerate aging, while naturally occurring caffeine slows age-related decline.

Problems With Caffeine

A study published in 2017 demonstrated that higher caffeine intake was associated with shorter telomeres (a marker of cellular aging) in adults. However, increased coffee consumption was linked to longer telomeres. This conundrum suggests that compounds other than caffeine in coffee may be providing the anti-aging effects.

These findings validated earlier ones that found greater coffee consumption was associated with longer telomeres. Researchers wrote, "On the surface, it might be assumed that caffeine intake and coffee consumption are essentially the same variable. They are not."

A 2023 study found instant coffee negatively affected telomere length. This was determined to be related to higher DNA-damaging lead content. Standard filtered coffee showed no adverse effects.

Authors of a study investigating caffeine from green tea, coffee, and soft drinks found that green tea protects against telomere shortening, while synthetic caffeine did not. Synthetic caffeine in the soft drinks was associated with DNA damage and accelerated aging.

Why Natural is Better than Synthetic

"Caffeine that is found in coffee or tea exists in a matrix of over 1,000 other chemical compounds, most notably polyphenolic compounds that have potent antioxidant effects," reported nutritionist David Wiss. For this reason, he said, both coffee and tea have anti-inflammatory properties that "isolated caffeine does not offer."

While coffee and tea have demonstrated protective effects against Parkinson's and Alzheimer's, these same studies also conclude that isolated caffeine fails to protect against neurodegeneration.

How Much Caffeine is Safe?

Naturally caffeinated food like chocolate contains about 12 mg of caffeine and beverages like coffee and tea contain up to 95 mg. Energy drinks can contain up to 300 mg of synthetic caffeine (see RockStar xDurance above). This is the reason the spike in caffeine content is associated with heart attacks in young people, while other studies show coffee and tea having a cardioprotective effect.

Dr. Wiss recommends that people "take a three-day (or longer) break from caffeine every three to six months." As I mention in my book , I would recommend avoiding coffee and sticking with water as the safest approach overall.

    Kitchen cooking oils will not last forever. Depending upon the oil, it can go rancid in a matter of months or a few years. You don't want to cook with rancid oil because it smells like wet socks and the living components have lost their vitality. But the good news is, expired oil won't hurt you. There is no water in it, so no mold can grow to make it rotten and dangerous. It can still be used for creative applications. According to the United States Department of Agriculture Forest Service, “Vegetable oils have many good natural properties including good lubricity, good resistance to shear, a high flash point, and a high viscosity index.” These qualities make them quite versatile in a number of applications. You might consider keeping your old oil rather than throwing it out. Recycling expired oil could prove to be a valuable asset in emergency situations.

    Disposable face masks, such as those health officials encouraged (or in some cases, mandated) the public to wear during the COVID-19 pandemic, are made of synthetic fibers and may contain chemical compounds. Many people have questioned the wisdom of wearing masks made of synthetic fibers for long periods, asking whether inhaling the chemical compounds masks release could lead to health problems.

    Deaths from Alzheimer's more than doubled between 2000 and 2019. In 2023, nearly 7 million Americans have been diagnosed with the disease. Today, 1 in 3 seniors dies with Alzheimer's or dementia—the death toll exceeds the total of breast- and prostate cancer combined. Officially, it's the sixth-leading cause of death, but a 2014 study suggests that it is actually one of the top three (just behind heart disease and cancer). The discrepancy being how death certificates underreport the disese because they record the more immediate cause of death (pneumonia or heart attack) rather than listing the underlyings causes.

    True confessions: I never liked flossing, so I rarely used the string. Angie used all of the flossing strings I collected from the dentist to cut the dough when making cinnamon rolls—I thought that was a better and tastier use! I always brushed my teeth (manually and with a battery operated toothbrush). My teeth felt clean enough, but still, I had a lot of dental guilt every 6 months when I had to admit I wasn't flossing. A few years ago, I found a device that removed all my guilt and shame! I discovered the waterpik. A waterpik (also known as a dental water jet) is a brand of water flosser or oral irrigator that sprays water to remove food from between your teeth. Water flossers are a fabulous option for people who have trouble with traditional flossing—the kind that involves threading string-like material between your teeth. The girl in the picture looks like me trying to floss!
