Healthy Fats in Nuts

The fat contained in nuts and seeds is almost exclusively unsaturated, with a good mix of both monounsaturated and polyunsaturated fats. Nuts and seeds typically feature very limited amounts of saturated fat, about 5-15% or less of their total fat content. The proper balance between these types of fats is important, and many people do not get enough of certain types, especially the polyunsaturated omega-3s. Many nuts and seeds-notably walnuts, flaxseeds, hemp seeds, and chia seeds-are rich sources of a type of omega-3 fat called alpha-linolenic acid (ALA), which belongs to the same family of omega-3 fats as the heart-healthy fats-EPA and DHA-you may have heard about in cold-water fish.

The omega-3 fatty acids found in nuts and seeds may help prevent heart disease and repeat heart attacks in several ways. Omega-3 fatty acids, including ALA, EPA, and DHA are protective fats that have been found to:

Omega-3's and Your Mood

Omega-3 deficiency can have an adverse effect on the mood. The body inefficiently synthesizes DHA, so we need dietary DHA from sources like oily fish. It offers a rich source of omega-3s—especially preformed EPA and DHA, the most neurologically active forms of omega-3s. Awareness of omega-3 benefits is growing; there was a 5% increase in awareness of the importance of omega-3s in brain health (from 17% to 22%) between 2006 and 2007. Omega 3s have been shown to improve the mood of menopausal and perimenopausal women, too, according to a February 2009 study in the American Journal of Clinical Nutrition.

You Can't Always Trust the FDA

Environmental Working Group exposes FDA plan to push mercury-laced seafood

On Friday, December 12, the Environmental Working Group made public internal government documents disclosing the Food and Drug Administration's secret plans to reverse federal warnings that pregnant women and children limit their fish intake to avoid mercury, a neurotoxin especially dangerous to the fetus and infants. EWG obtained both the FDA plan, stamped "CLOSE HOLD," and memos by senior Environmental Protection Agency scientists attacking FDA's rationale. The Washington Post broke the story, and other national stories followed.

Reaction from Capitol Hill was swift and sharp. Sen. Patrick Leahy, D-VT., denounced the FDA: "Now, in the administration's 11th hour, they are quietly trying to water down advisories for women and children about the dangers of mercury in fish, disregarding sound science on this issue. Mercury is a potent neurotoxin capable of impairing childhood development at very low levels."

What's Coming From Your Tap?

America's latest drinking problem isn't about alcohol.

Concerned about the cost of bottled water -- and its environmental consequences -- many people are turning back to tap water to quench their thirst. But as evidence mounts of contaminants in public systems, unease about the water supply is growing.

Engineers say that U.S. water quality is among the world's best and is regulated by some of the most stringent standards. But as detection technology improves, utilities are finding more contaminants in water systems. Earlier this year, media reports of trace amounts of pharmaceuticals in water across the country drew attention from U.S. senators and environmental groups, who are now pushing for regulation of these substances in water systems.

Of particular concern, experts say, are endocrine-disrupting compounds -- found in birth-control pills, mood-stabilizers and other drugs -- which are linked to birth defects in wildlife. Also alarming are antibiotics, which if present in water systems, even in small amounts, could contribute to the rise of drug-resistant strains of bacteria, or so-called super bugs.

The actual health effects of drugs in water systems are unclear. The levels that have been detected are relatively small compared with those of other regulated contaminants, such as mercury and benzene. A 2008 study funded by the Denver-based Awwa Research Foundation -- a nonprofit research group that was established by the American Water Works Association -- concluded that it is "highly unlikely" that pharmaceuticals will pose a threat to human health.

But many medical experts argue that more studies need to be done -- and note that the amount of drugs in the water matters less than who drinks it. Some drugs, even in small amounts, can be especially harmful to infants, pregnant women or those with chronic health conditions, for example.

Drugs are only one category of contaminants found in tap water. A 2005 study released by the nonprofit Environmental Working Group, found that tap water in 42 states is contaminated with more than 140 unregulated chemicals, including MTBE, perchlorate and industrial solvents.

Protesting a Disinfectant

Even chemicals used to clean and disinfect drinking water are causing worry. Citizens' groups in states such as CA, NY and VT are protesting the increasing use of chloramine -- a combination of chlorine and ammonia -- to disinfect drinking water. Utilities are using chloramine because of Environmental Protection Agency limits on chlorine byproducts.

Citizens Concerned About Chloramine in San Francisco, says that hundreds of residents have had reactions, such as rashes and respiratory problems, to the disinfectant. Some byproducts of chloramine can be more toxic than chlorine byproducts, says Michael Plewa, a professor of genetics at the U of Illinois who has studied disinfection byproducts.

The EPA says chloramine is safe in drinking water and has been used for decades.

In the absence of federal regulation of certain chemicals in water systems, some states have stepped in. California, for one, has set standards for various compounds that are not regulated by the EPA, including perchlorate, an ingredient used in rocket fuel that was spilled into groundwater during the Cold War and has been found in many water systems. Massachusetts has set standards for perchlorate and requires that water utilities in the state test for MTBE, a gasoline additive.

Tap Versus Bottled

Health concerns extend to bottled water, says Sarah Janssen, a science fellow at the Natural Resources Defense Council, or NRDC, a nonprofit environmental advocacy group based in NY. "A lot of bottled water is actually tap water, so there is no assurance that what is coming from the bottle is any safer than what is coming from the tap," she says.

In fact, experts say tap water is held to more stringent standards by the EPA, and tested more often, than bottled water, which is regulated by the Food and Drug Administration.

Utilities are required by law to send annual reports to their customers detailing contaminants found in water systems and whether they exceed levels set by the EPA. They're not required to list unregulated contaminants in these reports.

Water that is tested by utilities is generally tested at the plant. It still has to travel through your pipes to get to your tap, so if you have pipes that are a couple of decades old, it may be a good idea to get the water from your tap tested in a lab -- especially if you are pregnant, nursing or have small children, says the NRDC's Dr. Janssen.

Water filters aren't foolproof. Those that are certified by NSF International -- a nonprofit group that tests food and water products -- can get rid of unwanted chemicals to EPA's standards, but consumers should be aware that trace amounts of chemicals may still be left in their water.

Carbon filters, which come in the form of a faucet mount or a pitcher, are the most commonly used and cost about $30, says Rick Andrew, operations manager of the drinking water treatment unit program at NSF. These can be fairly effective in removing many contaminants, but need to be replaced about every two months.

Other options -- such as reverse-osmosis systems, which use a semipermeable membrane to remove contaminants, or ultraviolet light treatment, which prevents micro-organisms from reproducing -- can be more effective, but they cost hundreds or even thousands of dollars. Some consumers have found the cost is worth it, especially if members of the family have certain health conditions.

The Safety of Our Food in Jeopardy!

On October 5, the EPA approved a new chemical fumigant for use on strawberries and other food crops across the U.S. The pesticide, methyl iodide, vaporizes quickly, causing it to drift far distances. Although the state of California has categorized it as cancer causing, and the EPA admits it causes thyroid tumors, the Bush Administration has been advocating approval of the fumigant for the better part of two years. In a letter to EPA Administrator Stephen Johnson on September 25, the nation's leading chemists asked EPA not to approve methyl iodide without further scientific review. The chemical has been used to induce cancer in laboratory experiments and causes neurological and thyroid problems, as well as miscarriages in studies with laboratory animals. Farmworkers, families, rural workers, and the food supply will now be subjected to exposure to the carcinogen unless the EPA revokes the approval immediately.
