Does Coffee Inhibit Iron Absorption? What Are the Effects of Having Too Much Iron?
Coffee and common herbal teas impair iron absorption, which may help explain some of their benefits.
Topic summary contributed by volunteer(s): Linda
Parkinson’s disease is a progressive disorder of the nervous system that affects a person’s movement. Parkinson’s is diagnosed in more than 50,000 Americans each year and is now the 15th leading killer in the U.S.
There have been reported Parkinson’s cases among people who have worked for years in pesticide production plants. There may be a link between dairy product intake and risk for Parkinson’s disease, caused perhaps by low levels of neurotoxic chemicals in cheese and banned pesticides in contaminated dairy products.
Beta-carboline neurotoxins, which can be found in beef, chicken, pork, and fish, have been linked to cases of Parkinson’s disease, tremor, addiction, and cancer. A USDA study found about one in six U.S. lambs infected with the parasite toxoplasma, which has been linked to risk for Parkinson’s, schizophrenia, and bipolar disorder. Excess iron intake and nitrites, found in cured meats, appear to be linked with Parkinson’s. BMAA, a neurotoxin that can be found in seafood and blue-green algae, may be linked to risk for Parkinson’s disease, ALS, and Alzheimer’s disease.
Filtered coffee may protect against Parkinson’s. Regular intake of cooked or sprouted beans may also help lower risk against neurodegenerative disorders like Parkinson’s, Lou Gehrig’s disease, and Alzheimer’s. Many modern drugs, including those used to treat Parkinson’s, are derived from plants. A whole foods, plant-based diet, may help in the treatment of Parkinson’s symptoms.

Oxidized cholesterol can be a hundred times more toxic than regular cholesterol, raising additional concerns about foods such as ghee, canned tuna, processed meat, and parmesan cheese.
Are the health benefits associated with apple consumption simply due to other healthy behaviors among apple-eaters?
The link between Parkinson’s and dairy may not be explained just by the pesticides and lactose.
Neurotoxin contamination of the dairy supply doesn’t explain why the association between Parkinson’s and skim milk consumption is as strong as the disease’s association with whole milk.
In this “best-of” compilation of his last four year-in-review presentations, Dr. Greger explains what we can do about the #1 cause of death and disability: our diet.
Berries counteract the neurotoxic effects of pesticides in vitro, potentially explaining why berry consumption is associated with lower risk of developing Parkinson’s disease.
Might the nicotine content in nightshade vegetables, such as tomatoes, potatoes, eggplants, and bell peppers, protect against Parkinson’s disease?
The tobacco industry points to dozens of studies purporting to show tobacco use is associated with a lower incidence of Parkinson’s disease.
Dr. Greger has scoured the world’s scholarly literature on clinical nutrition and developed this new presentation based on the latest in cutting edge research exploring the role diet may play in preventing, arresting, and even reversing some of our most feared causes of death and disability.
Organic food consumption appears to reduce exposure to pesticide residues and antibiotic-resistant bacteria.
A neurotoxin called BMAA that concentrates in seafood may help explain clusters of Lou Gehrig’s disease.
The neurotoxin BMAA is found in seafood and the brains of Alzheimer’s and ALS victims. Might dietary changes help prevent amyotrophic lateral sclerosis?

For more than 30 years, the medical profession has debated the existence of an intolerance to the wheat protein, gluten, unrelated to allergy or celiac disease. What is the evidence pro and con?
Neurotoxins in chicken, such as the beta-carboline alkaloid harman, may explain the link between meat consumption and hand tremor, the most common movement disorder.
Plant-based diets in general, and certain plant foods in particular, may be used to successfully treat Parkinson’s disease—in part, by boosting L-DOPA levels.
Low levels of neurotoxic chemicals in cheese may explain the connection between dairy product consumption and Parkinson’s disease.
Iron is a double-edged sword. If we don’t absorb enough, we risk anemia; but if absorb too much, we may increase our risk of cancer, heart disease, and a number of inflammatory conditions. Because the human body has no mechanism to rid itself of excess iron, one should choose plant-based (non-heme) sources, over which our body has some control.
Death in America is largely a foodborne illness. Focusing on studies published just over the last year in peer-reviewed scientific medical journals, Dr. Greger offers practical advice on how best to feed ourselves and our families to prevent, treat, and even reverse many of the top 15 killers in the United States.
Phytonutrients, such as vitamin C, prevent the formation of nitrosamines from nitrites—which explains why adding nitrite preservatives to processed meat can be harmful, but adding more vegetables, with their nitrite-forming nitrates, to our diet can be helpful.
Many of the most powerful drugs in modern medicine’s arsenal came from natural products, from penicillin to the chemotherapy agents Taxol® and vincristine.
In a double-blind study, the spice saffron beat out placebo in the treatment of Alzheimer’s disease dementia symptoms.
The risks associated with these supplements may outweigh the benefits.
