Salt is a cheap, easy way to turn on taste buds. That’s one reason why it’s in so many of the foods we eat. It’s so commonly used that most Americans consume more than double the recommended daily limit for it. Three new studies in BMJ (formerly the British Medical Journal) once again confirm the relationship between salt intake and health problems. They show that reducing salt intake can help lower blood pressure and lower the odds of having a heart attack or stroke or developing heart failure. They also show that consuming more potassium is also linked to lower blood pressure and lower risk of stroke. Current dietary guidelines recommend that Americans get no more than 1 teaspoon of salt a day. That’s the equivalent of 2,300 milligrams (mg) of sodium a day. Most Americans get much more than that. It’s possible to cut back by avoiding processed and packaged foods, using herbs and spices to season food instead of salt, and other strategies. It’s best to get potassium from food, especially fruits and vegetables. Green leafy vegetables, beans, and bananas have a lot of potassium.

Taking care of yourself and your nuclear family is not always easy. Add the need to take care of an aging and ailing parent or family member and the stress can become overwhelming. According to some estimates, more than 40 million adults in the United States care for older or sick adult relatives or friends on a regular basis. AARP has estimated that these family and friends provide up to $450 billion worth of care. The responsibility often falls on family members, because long-term care outside the home can be very expensive and most Americans can’t afford private long-term care insurance that might cover these costs. Regular health insurance, or Medicare, does not pay for the kind of regular daily care many adults need later in life. A new ad campaign sponsored by AARP (formerly the American Association of Retired Persons) and the nonprofit Ad Council wants caregivers to know that they are not alone and that help is available. The goal of the ads is to raise awareness of the effects that family caregiving can have and to help people find the resources they need to reduce the stress.
Thanks to medical advances in detecting and treating stroke, the risk of dying from one is now lower than it used to be. Unfortunately, many stroke survivors are left with a disability. In fact, stroke is the leading cause of serious long-term disability in the United States. A new study from Indianapolis suggests that yoga may benefit some stroke survivors. In this study, 47 stroke survivors were divided into three groups. Some took part in a twice weekly group yoga session for eight weeks, and others received standard follow-up but no yoga. There were several benefits in the yoga group, including improved balance, improved quality of life, reduced fear of falling, and better independence with daily activities. Although small, this study adds to findings from other research that yoga may help stroke survivors in several ways.
