There are several things you can do to prevent or minimize the aches and pains that might accompany statin use.

If you're not taking a statin now, you may well be soon. These medications are commonly prescribed to lower "bad" LDL cholesterol and have been shown to reduce the risk of heart attack, stroke, and death. They are routinely recommended for people who have cardiovascular disease and for many people ages 40 to 75 who don't have cardiovascular disease but have at least one risk factor (high blood pressure, high cholesterol, diabetes, or smoking) and a 7.5% or greater risk of a stroke or heart attack in the next decade. Moreover, recent research indicates that they may benefit high risk individuals over age 75 as well.

Muscle pain and other statin side effects

Taking a statin may give you some assurance that you're doing all you can to avoid heart attack and stroke, but you may also experience side effects. Reported side effects include an increased chance of developing diabetes — which is largely restricted to people who are already at risk for diabetes, and who can be monitored with glucose or hemoglobin A1c tests. Statin use has also been associated with difficulties with memory and reasoning, although there is no clear evidence that the drugs were responsible. In very rare cases, statins may cause liver problems or a potentially life-threatening breakdown in muscle cells.

Take advantage of the many delivery options to keep your diet fresh, healthy, and full of variety.

Getting groceries or prepared meals without leaving your couch is easier than ever in this era of home delivery. That's important for people who have difficulty getting to the grocery store because they don't drive or because they're struggling with a chronic condition.

But the many options for food delivery may have you wondering where to begin. Here's a look at some widely used services and what to keep in mind when you use them.

Prescription and over-the-counter medications may affect you differently now.

Despite the beneficial effects of medications, some drugs need to be used with increasing caution as you age. Drugs that caused few if any side effects in your youth can now cause discomfort or even put you at risk for serious problems such as falls or bleeding.

What's different in older age?

Even though you may have taken a medication for decades, your body may react differently to it later in life. One reason for this is that your metabolism has slowed down. Some medicines need to be processed by your liver to benefit your health; slower digestion and liver function mean it may take longer for a drug to get into your bloodstream. Later, remnants of the medicine need to be eliminated from your body by the liver and kidneys. Slowdowns at this stage mean it may take longer for a drug to leave your body, so its effects last longer.

Vitamins and supplements won't help stave off dementia, but a healthy lifestyle might, suggest new guidelines released May 19, 2019, by the World Health Organization (WHO). The WHO warns that the number of new dementia cases around the world — currently 10 million per year — is set to triple by 2050. While there's no cure for any kind of dementia (such as Alzheimer's disease and vascular dementia), the WHO says it may be possible to delay the onset of the disease or slow its progression. The key: managing modifiable risks, such as chronic disease and unhealthy habits. The guidelines recommend that you keep your weight, cholesterol, blood pressure, and blood sugar under control; get lots of exercise; and eat a Mediterranean-style diet (which emphasizes olive oil, fruits, vegetables, nuts, and fish; minimizes red meats and processed meats; and includes a moderate amount of cheese and wine). The WHO also advises that you don't smoke and you avoid harmful use of alcohol (no more than one drink per day for women, no more than two drinks for men). But don't count on supplements to help you stave off dementia. The WHO says there's no evidence that vitamin B, vitamin E, multivitamins, or fish oil supplements help reduce the risk for dementia. The agency recommends against using supplements as a means to ward off cognitive decline.

Eating food that's ultra-processed — not just chips or cookies, but also things like breakfast cereal, deli meat, or canned fruit in syrup — makes people overeat and gain weight, compared with eating food that's unprocessed. That's according to a small randomized controlled trial published online May 16, 2019, by Cell Metabolism. It involved 20 men and women who stayed at a research facility for a month and were randomly assigned to one of two diets. One group was given ultra-processed foods (such as a breakfast of a bagel with cream cheese and turkey bacon), and the other group was fed unprocessed foods (such as a breakfast of oatmeal with bananas, walnuts, and skim milk). After two weeks, participants were switched to the opposite diets. Both diets were evenly matched for total calories, macronutrients, fiber, sugars, and sodium, and participants were allowed to eat as much or as little as they wanted. But they ate more calories when they were eating ultra-processed foods, compared with when they ate unprocessed foods, and they gained more weight on the ultra-processed diet. Why? It's not exactly clear, but researchers did find that appetite-suppressing hormones decreased and hunger hormones increased when people ate processed foods. Bottom line: Eat whole, unprocessed foods with as few ingredients as possible.

How many daily calories do you really need? It depends on many factors.

When it comes to nutrition, calories embody the ultimate love-hate relationship. Consume too little, and you don't have the energy to function at your best. Eat too much, and you risk weight gain. It's no surprise, then, that counting calories can be such an obsession.

But how much do you really need every day? Unfortunately, there is not a single, simple answer. Men ages 50 and older require 2,000 to 2,800 calories per day, or an average of about 2,500, says Dr. Qi Sun, associate professor in the Department of Nutrition at the Harvard T.H. Chan School of Public Health.

Another way to lower LDL (bad) cholesterol levels? Eat more soy protein, suggests a study published online April 22, 2019, by The Journal of Nutrition.

Researchers examined 43 trials to evaluate the effect soy had on LDL levels. (High LDL levels can lead to a buildup of cholesterol in arteries and increase a person's risk of cardiovascular disease.)
