Causes, Diet: Prevention, Willett clip 2
Professor Willett explains that we can't be 100% sure if the lycopene from a supplement is really going to be the same as eating tomatoes, which are high in lycopene.
Walter Willett is the Fredrick John Stare Professor of Epidemiology and Nutrition at the Harvard School of Public Health. HIs research focuses on how dietary factors may contribute to and cause health-related conditions. He has written a book entitled Eat, Drink and Be Happy, which summarizes some of the results from his research. â€œWe can't be 100% sure if the lycopene from a supplement is really going to be the same as eating tomatoes, which are high in lycopene. First of all, what we see in our studies is that people who eat more tomatoes and tomato products have had a lower risk of prostate cancer. And it's a hypothesis that lycopene is the active agent but it's actually possible that it's something else in tomatoes or the combination of several factors in tomatoes that's related to lower risk of prostate cancer. And it will really require a separate study giving supplements of lycopene for many years to see if that specifically was the active factor that was related to lower risk of prostate cancer and that study hasn't been done yet.â€

986. Causes, Diet: Prevention, Willett clip 1
Professor Willett explains that for overall cancer reduction by diet, the most important thing is keeping calories in balance with our physical activity, which means staying as lean and active as we can throughout our life.
984. Causes, Diet: Prevention
In addition to enzymes produced by the body, certain components in food can also react with damaging chemicals, and an increased consumption of these foods may lower a person’s risk of cancer development.
1025. Causes, Diet
In order to identify cancer causes and prevention strategies, researchers conduct a cohort of studies where they collect information from large groups of individuals over many years.
988. Causes, mold
Aflatoxin, a byproduct of molds, is a potent cancer-causing agent. Long-term exposure to aflatoxin has been linked to increased incidence of liver cancer.
993. Causes, Mold: Incidence, Groopman
Professor Groopman explains that we have an effective vaccine against the hepatitis B virus, but because the transmission of this virus occurs very early in life, we need to have the resources and the ability to vaccinate the world for the rest of the 21s
990. Causes, Mold: Aflatoxin, Groopman
Professor Groopman explains that Aflatoxin is produced by a variety of molds and these molds contaminate the grains either outside or they can actually penetrate inside the grains.
995. Causes, Mold: Aflatoxin action, Kensler
Professor Kensler explains that the importance of aflatoxin and the causation of liver cancer results from a life long series of exposures.
994. Causes, Mold: Aflatoxin action
Aflatoxin causes DNA damage and with prolonged exposure to aflatoxin, cells accumulate DNA mutations and thus are at increased risk of developing into cancer cells.
992. Causes, Mold: Incidence
Mold-contaminated crops can be a serious problem especially in countries where proper storage facilities are limited.
954. Causes, Smoking, all sections
This section explains that lung cancer is the leading cause of cancer deaths in the United States and it is almost entirely preventable, since the vast majority of cases are due to cigarette smoking.
