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!
Shingles is a viral infection caused by the activation of the varicella-zoster virus (VZV), also called human herpesvirus 3. That's the same virus that causes chickenpox. If you have ever had chickenpox, you were exposed to the varicella-zoster virus, which stays in your body for the rest of your life. If this occurs, the virus can reactivate as shingles years later. Being exposed to children with chickenpox keeps adult immunity up and reduces the chance of shingles in the future. Unfortunately, because we have largely eliminated chickenpox in kids, there is no repeated exposure to the virus to keep shingles at bay. The medical community has traded a kid's disease with few side effects for an adult disease with a lot of pain and discomfort. The VZV is a member of the herpes family of viruses. When shingles develops, it affects the nerves throughout the body resulting in painful, uncomfortable symptoms.
There are no easy answers for those who struggle with sleeping at night. Without a good night's sleep, our body's repair systems begin to struggle. A hormone we are familiar with has a little-known role in managing sleep. Cortisol is a steroid hormone that helps the body respond to stress and danger. It's also known as the "stress hormone" and is produced in the adrenal glands, which sit on top of each kidney. The hypothalamus-pituitary-adrenal axis regulates cortisol production and secretion. But I didn't realize it played an important role in keeping us from sleep.
A recent study on sialic acid (a sugar) shines a bright light on an established risk factor for cancer. Scientists and doctors have known long-term consumption of red meat (beef, pork and lamb) is highly correlated to cancer. For years, researchers have looked for specific mechanisms in the meat that would cause human carcinomas. Grilling red meat was thought to create DNA damage due to mutagens, which are chemicals that mutate DNA. But that theory didn’t pan out. Grilling poultry and fish generates the same mutagens, but fish and poultry are not associated with an increased risk of cancer.
A false paradigm is a belief system that is incorrect. For centuries, people believed the sun went around the Earth. People looked up in the sky and it happened every day without fail. However, it was Copernicus in 1543 and Galileo in the 1600s who finally advanced the idea that what everyone saw each day was an illusion: the Earth actually went around the sun. Mark Twain stated, "It's not what we don't know that prevents us from succeeding; it's what we KNOW that just ain't so." I will discuss 5 false paradigms below.
The diverse roles glycans play in the body are simply astounding. As communication sugars, they represent the language of life. That is impressive enough by itself, but they do much more. Glycoproteins hold cells together. When they perform this function, they are referred to as cell adhesion molecules (CAMs). They govern the stickiness of cells—how they clump or align and stick together. When adhesion fails in cancer cells, scientists call this metastasis.
