Low-level exposure to toxic metals: A risk for clogged arteries?

Being exposed to even low levels of certain toxic metals, including arsenic, cadmium, and titanium, may raise a person’s risk for clogged arteries.

The heart-related hazards of air pollution

Air pollution is an often overlooked yet important contributor to cardiovascular disease. Tiny particles known as PM2.5 travel deep into the lungs, where they irritate receptors and trigger nerves involved in the autonomic nervous system. This irritation also contributes to inflammation, which accelerates atherosclerosis. Climate change can worsen the damaging effects of air pollution in several ways, such as by promoting wildfires and dust storms, which creates more PM2.5. To reduce pollution’s harmful effects, people can check air quality information and use portable indoor air cleaners when pollution levels are elevated.

Even low-level air pollution may harm health

The burning of fossil fuels is a major contributor to climate change, and pollution from this burning has been linked to millions of premature deaths worldwide. And, according to a new report, even low levels of air pollution may harm our health although we can take steps to limit exposure.

Take the lead on lead poisoning

The use of lead in consumer products was banned in the United States in 1978, but lead exposure is still a serious problem today, especially for young children.

When should children be tested for lead exposure, and what should parents do if there is lead in their home?

Most people have heard the nutritional recommendation to eat five servings of fruit per day. But are some fruits better for you than others? Is it okay to eat dried or frozen fruit, or to drink fruit juice? Does it have to be organic?

Chemical in plastics and personal care products linked to heart disease

Exposure to chemicals called phthalates, found in commonly used plastics, may be linked to a higher risk of dying from cardiovascular disease.

Reduce the health risks from "forever chemicals"

Per- and polyfluoroalkyl substances (PFAS) are a group of thousands of manmade chemicals that are widely used in products such as nonstick pans, stain repellants for furniture and carpets, cosmetics, and industrial products. These compounds are dangerous to human health and may lead to immune system problems and increased risk of certain cancers. Avoiding exposure by filtering water and choosing PFAS-free products can help to reduce those risks.

Ban on harmful pesticide: What parents need to know

After two decades of concern, and mounting evidence of its harm to young children, the FDA has banned the pesticide chlorpyrifos from use on food. But it's important to remember that chemicals are everywhere, and there are other steps all parents should take to protect their children from exposure to potentially harmful products and substances.

Air pollution: How to reduce harm to your health

Some air pollution levels have inched up in recent years, and accumulating evidence suggests that higher levels of particulates in the air are linked with increased levels of hospitalization for many serious health problems. But we can make choices to help both the environment and our health.

7 strategies to prevent cancer

Making healthy lifestyle changes can prevent an estimated 40% of cancers. These include eating a healthy diet, exercising regularly, getting adequate sleep, and maintaining a healthy body weight. People can also help prevent cancers by seeking recommended cancer screenings.
