Cysteine gum may reduce tobacco, alcohol cancer risk NutraIngredients.com
2006.05.23
So what's a person to do if they want a tipple? l-cysteine might be the answer.
"...The gum, called XyliCyst, is to be introduced by Finnish company Biohit Oyj, which holds the patents to the preparations to use I-cysteine to eliminate the carcinogen acetaldehyde after drinking or smoking...I-cysteine has been understood for many years to have the ability to bind to acetaldehyde, or ethanal, a toxic chemical compound that forms in saliva, especially with alcohol drinking and tobacco smoking...According to Finnish researchers Professors Mikko Salaspuro and Martti Marvola, epidemiological statistics indicating that 80 per cent of cancers of the mouth, pharynx and oesophagus are linked to smoking and drinking could be explained by increased exposure to acetaldehyde in the upper digestive tract..."
If you understand Finnish you can buy the gum here. Being the monoglot that I am, I have to wonder about l-cysteine supplements rather than gum.
Info on l-cysteine here, with this interesting nugget "Cysteine-supplemented mice and guinea pigs have enjoyed significantly extended life spans, and other animals, challenged with various toxins, have, when pre-supplemented with cysteine, survived considerably longer than non-supplemented controls. In one of these studies, 90% of control rats given large doses of acetaldehyde died. But other rats first given a combination of vitamins C and B, along with cysteine, and then exposed to the same dose of acetaldehyde, all survived. Cysteine's protective mechanisms could relate to its own antioxidant properties, its promotion of glutathione (a major antioxidant) or even, it has been hypothesized, to some ability to participate in DNA repair.""
What about dosage? "The usual supplemental dosage of L-cysteine is 500 milligrams to 1.5 grams daily. Those who supplement with L-cysteine should drink at least six to eight glasses of water daily in order to prevent cystine renal stones. Some studies indicate that an intake of 3 to 5 grams daily of vitamin C may prevent cystine stones. However, high-dose vitamin C itself may contribute to renal stones in some (see Vitamin C).""...Another delivery form of L-cysteine is N-acetylcysteine (see N-Acetylcysteine)."
LifeExtension lists their treatments for dealing with alcohol here. They actually sell an anti-alcohol antioxidant supplement. And cysteine is one of the ingredients.
One of the reasons you probably don't want to take this at high doses - might act as a neurotoxin.

More bad news for those of us who occasionally like to imbibe.
"...According to CAMH Principal Investigator Dr. Jürgen Rehm, existing research consistently shows a relationship between alcohol consumption and an increased risk for cancer of the esophagus, larynx and oral cavity...
- The risk of esophageal cancer nearly doubled in the first two years following alcohol cessation, a sharp increase that may be due to the fact that some people only stop drinking when they are already experiencing disease symptoms. However, risk then decreased rapidly and significantly after longer periods of abstention.
- Risk of head and neck cancer only reduced significantly after 10 years of cessation.
- After more than 20 years of alcohol cessation, the risks for both cancers were similar to those seen in people who never drank alcohol.

Some other studies, however, have required much longer periods of supplementation for various antioxidants to improve cognitive performance...The scientists suggested in the paper that long-term supplementation “may be effective in attenuating age-associated cognitive decline by slowing the rate of mitochondrial decay and cellular aging.” Enhancing the function of mitochondria - which provide almost all of a cell’s energy - could literally be providing animals with more “mental energy,” leading to improved memory and learning, the study indicated. The compounds may also cause increased synthesis of a neurotransmitter called acetylcholine...An increasing body of research suggests that mitochondria may be an “Achilles heel” for absorbing age-related damage, as part of the natural process of oxidation in the body and the related “free radicals” that are produced and can cause cellular damage.

"Mice containing a mutated human gene implicated in autism exhibit the poor social skills but increased intelligence akin to the title character’s traits in the movie “Rain Man,”... Some cases of autism are genetically linked and have been associated with mutations that affect molecules called neuroligins, which link nerve cells together... In the latest study, the researchers introduced a mutated human form of the neuroligin-3 molecule into mice. They then tested the animals’ social interactions by exposing them to an unknown mouse in a cage. The genetically engineered mice spent less time near the strange mouse than their normal littermates and preferred to spend time with inanimate objects... The engineered mice were significantly better than normal, though, at learning a water maze, in which they had to find and learn the location of an underwater platform. They were also better at relearning a new position of the platform after it was moved...“When you manipulate a brain, you usually don’t improve it,” Dr. Südhof said. “The fact that we get an improvement is very good. It shows we’re changing something specific; we’re affecting how the brain processes information.”..."

"Embedded deep under its blubber was a 3½-inch arrow-shaped projectile that has given researchers insight into the whale’s age, estimated between 115 and 130 years old. …
Calculating a whale’s age can be difficult, and is usually gauged by amino acids in the eye lenses. It’s rare to find one that has lived more than a century, but experts say the oldest were close to 200 years old."
"...Whether they age or not, whales demonstrate that mammals can live at least twice as long as humans, raising the question of how they do it. As intractable a model system as even small whales might be for the average bench scientist, it would nonetheless be fascinating to study age-related phenomena in these creatures, perhaps in a cell-culture system where we could ask questions about their cellular senescence, DNA repair, and oxidation."

More vitamin D could mean fewer cancers
More vitamin D could mean fewer cancers: study Reuters/Yahoo! 2007.09.04 "Thousands of cases of breast and colon cancers might be averted each year if people in colder climates raised their vitamin D levels...rates of breast, colon and ovarian cancer, for example, are lower in sunnier regions of the world than in Northern climates where cold winters limit people's sun exposure...lab experiments showing that vitamin D helps prevent cancer cells from growing and spreading, as well as some clinical trials in which people given high doses of vitamin D showed lower cancer risks... The protective effect against colon cancer seemed to begin when blood levels of vitamin D reached 22 nanograms per milliliter (ng/mL); for breast cancer, that number was 32 ng/mL. The average late-winter vitamin D level among Americans is 15 to 18 ng/mL, according to the researchers...They argue that, based on their data, if Americans were able to maintain a vitamin D level of at least 55 ng/mL, 60,000 cases of colon cancer and 85,000 cases of breast cancer could be prevented every year. Worldwide, those figures could be 250,000 and 350,000, respectively..."This could be best achieved with a combination of diet, supplements and short intervals -- 10 or 15 minutes a day -- in the sun," lead study author Dr. Cedric F.Garland..."
