Autophagy means "self-eating". When a cell is damaged or dies, the body quickly breaks down the dead cell’s parts (protein-making, power-generating, and transport systems) into small molecules that can be reassembled to be used for making new cell parts and supplying the energy to power these processes.
Dry skin on any part of the body can be annoying and can cause flaking and cracking, redness due to scratching, and unsightly patches of thick or hard skin. When dry skin occurs on the feet, the symptoms are magnified due to wearing shoes, the stretching of the skin on the feet with every step . . .
For many years I have offered my opinion that sunlight provides benefits that are not gained just from taking vitamin D pills. Recent research is confirming that opinion, and many scientists now believe that low vitamin D blood levels are only a marker for not getting enough sunlight.
Colds and pneumonia are caused by infection. You do not pick up infections from cold weather, you get germs from other people who sneeze or cough in your face or transmit germs with their hands to objects that you touch.
Dementia means loss of brain function, and your chance of having dementia increases with age: it affects three percent of people ages 65-74, 17 percent of those age 75-84 and 32 percent of those age 85 or older. Doctors can now predict increased risk for developing dementia by ordering an MRI which can show decreased volume of grey matter in the brain.
Sunscreens offer only partial protection from the sun. It is dangerous to expose large areas of your sun screen-coated skin to sunlight. If you want to really protect your skin from sun damage, get under a roof when the sun is out in full force. Clothes are next best, and sunscreens are a poor third.
Your body uses inflammation to protect you from invading germs and to heal injuries. When a germ gets into your body, you make cells and proteins to kill that germ. As soon as the germ is gone, your immune system is supposed to dampen down and stop making large amounts of these cells and antibodies.
A study of 58,769 patients over 55 years of age diagnosed with dementia and 225,574 people of the same age without dementia found a 50 percent increased risk of dementia among people who used a strong anticholinergic drug daily for about three years within the 10-year study period
Your liver is the organ that picks up breakdown products of your own metabolism and removes them from your body. The promoters of liver-detoxifying supplements tell you that their products "support healthy liver function" and help it do its job better.
2019 Nobel Prize honors the discovery of how your body responds when you can't meet your needs for oxygen. Their groundbreaking research is now being used to treat certain cancers, strokes, infections, anemia, heart attack risks, and some eye diseases that can cause blindness.
If you belch or have burning in your stomach or chest, particularly when your stomach is empty, you probably have either an infection, a tumor, or a condition called GERD (reflux or regurgitation). Infection with bacteria such as helicobacter pylori is by far the most common cause.
At last, the U.S. Food and Drug Administration (FDA) is proposing new rules on sunscreen safety. Finalizing these rules and actually making changes on the regulation or labeling of sunscreens will take time, so I advise you to follow their recommendations now by reading the labels and avoiding those products with ingredients that are unlikely to be safe or may be found unsafe. Here are the proposed rules.
More than 30 percent of North Americans over the age of 85 suffer from dementia. A study presented recently at the International Stroke Conference 2019 shows that having harmful bacteria in your colon increases risk for dementia.
New studies show that two auto-immune diseases, chronic fatigue syndrome and rheumatoid arthritis, may be caused by having pro-inflammatory bacteria in your gut. These bacteria are likely to punch holes in your intestines, which allows bacteria to slip into your bloodstream to cause inflammation.
A study from Columbia Medical School shows that a high fiber diet that is low in sugar and saturated fat can help you to fall sleep faster and sleep deeper at night. A single day of increased sugar and fat and decreased fiber intake can interfere with your sleep that night.
A study of more than two million people showed that being overweight markedly increases risk for at least nine different cancers in men (bladder, colorectum, gallbladder, kidney, liver, lung, lymphatic system, pancreas, stomach) and eleven cancers in women (gallbladder, kidney, liver, lung, lymphatic system, ovaries, pancreas, stomach, uterus, cervix, and endometrium).
Results from the huge EPIC study (European Prospective Investigation into Cancer and Nutrition) confirm that eating a lot of junk food increases risk for many cancers. Researchers in Paris followed 471,495 adults in 10 European countries for an average of 15.3 years, and the participants developed 49,794 cancers. The participants' diets were scored using the British Food Standards Agency's Nutrient Profiling System (FSAm-NPS), which ranks foods according to their healthful and harmful components. Those who ate more of the harmful and less of the healthful food components were at significantly greater risk for developing cancers, particularly cancers of the breast, prostate, colon-rectum, mouth, throat, esophagus, stomach, lung and liver.
It only takes one injection each year to protect you from the flu. The vaccine is very safe and cannot cause disease because it is made from killed virus. The most common side effect is a sore arm from the injection. Some people may suffer a few hours of fever, muscle pain, and chills.
For many years we have been told to watch existing moles for changes that may signal a melanoma, but a new review of 38 studies covering 20,126 melanomas shows that fewer than 30 percent of melanomas are found on moles. More than 70 percent of melanomas show up on previously normal skin.
Thirteen percent of North American men and seven percent of women suffer from kidney stones which can be incredibly painful to pass from the kidneys to the bladder. Those who get one stone have a 50 percent chance of passing another stone within the next five years. Here are the current recommendations for preventing kidney stones:
More than 1.3 million North Americans have had colorectal cancer, a disease associated with behaviors that encourage cancer-causing bacteria to thrive in your colon. Colon cancer is linked to lifestyle factors that increase inflammation risk: an unhealthful diet, lack of exercise, excess weight, smoking, and alcohol consumption.
More than one million North Americans are diagnosed each year with skin cancers. Twenty percent of people have the bacterium called Staphylococcus epidermidis living on their skin. It produces molecules that have been shown to slow or stop the development of skin cancers in mice.
Nearly fifty percent of people over 85 suffer from symptoms of dementia of which Alzheimer's disease, a progressive loss of brain cells, is the most common form. The second most common type of dementia comes from repeated strokes. This month researchers offer strong evidence that Alzheimer's disease may be started by an infection.
The alcohol industry is downplaying the cancer risks of their products in the same way that the tobacco industry did 70 years ago. The alcohol industry claims that moderate drinking is safe, yet thirty percent of all alcohol–related deaths are caused by cancer, with 60 percent of these deaths from breast cancer.

Debilitating constipation affects 16 percent of North Americans and 33 percent of those older than 60. This epidemic of constipation is largely caused by a food industry that produces mostly ultra-processed foods that contain little or no fiber. People keep looking for constipation cures in a pill, but it is usually curable just with simple lifestyle changes.
Almost all skin cancers are caused by excessive exposure to sunlight. Basal and squamous cell skin cancers are caused by cumulative exposure to sunlight over a lifetime, so every time you expose any part of your skin to direct sunlight, you are adding to the damage that you have received from previous exposures.
Stem cell clinics have sprung up in most states, but are most abundant in Arizona, California, Colorado, Florida, New York and Texas. Last year the FDA sent warning letters to clinics in California, Florida and New York for illegally using stem cells from people's fat tissue to treat conditions such as Parkinson's disease.
Edges of toenails that press into the flesh can cause pain, swelling, redness, and even infection. Your skin may start to grow over the ingrown toenail. Treatments include special chemicals, lasers, and various ways to remove the edge of the nail that presses into the skin.
