It might. Eating more whole-grain foods on a regular basis might help reduce your chance of developing high blood pressure (hypertension).

Whole grains are grains that include the entire grain kernel — they haven't had their bran and germ removed by refining. Whole-grain foods are a rich source of healthy nutrients, including fiber, potassium, magnesium, folate, iron and selenium. Eating more whole-grain foods offers many health benefits that can work together to help reduce your risk of high blood pressure by:

• Aiding in weight control, since whole-grain foods can make you feel full longer
• Increasing your intake of potassium, which is linked to lower blood pressure
• Decreasing your risk of insulin resistance
• Reducing damage to your blood vessels

If you already have high blood pressure, eating more whole-grain foods might help lower your blood pressure.

The Dietary Approaches to Stop Hypertension (DASH) diet and the Mediterranean diet both recommend including whole grains as part of a healthy diet.

According to the Dietary Guidelines for Americans, as part of an overall healthy diet, adults should eat at least 85 grams of whole-grain foods a day — that's about 3 ounces, or the equivalent of three slices of whole-wheat bread.

Yoga might have benefits for caregivers of people with Alzheimer's disease or another type of dementia.

Yoga brings together physical and mental disciplines to help you achieve peacefulness of body and mind. The practice focuses on postures (poses), breathing techniques and meditation.

While research on the benefits of yoga for caregivers is limited, a small number of studies suggest that yoga might:

• Improve depression symptoms
• Lower anxiety levels
• Reduce stress
• Lower blood pressure
• Improve the ability to cope

One study found that caregivers who participated in an eight-week yoga group experienced physical and emotional benefits, which helped lessen any guilt they felt for taking time for themselves. Participants also reported feeling peaceful and relaxed during their yoga practice.

There are many different types and styles of yoga, and some are more intense and vigorous than others. Check with your doctor before starting yoga, especially if you have any health conditions. If finding time to attend a yoga class is challenging, seek out a mix of in-person and online classes.

After having their gallbladder removed (cholecystectomy), some people develop frequent loose, watery stools. In most cases, the diarrhea lasts no more than a few weeks to a few months. There isn't a specific gallbladder removal diet that you should follow if you have this problem, but there are a few things you might consider.

First, it helps to understand why you're having diarrhea. Diarrhea after gallbladder removal seems to be related to the release of bile directly into the intestines. Normally, the gallbladder collects and concentrates bile, releasing it when you eat to aid the digestion of fat. When the gallbladder is removed, bile is less concentrated and drains more continuously into the intestines, where it can have a laxative effect.

The amount of fat you eat at one time also plays a role. Smaller amounts of fat are easier to digest, while larger amounts can remain undigested and cause gas, bloating and diarrhea.

Although there isn't a set gallbladder removal diet, the following tips may help minimize problems with diarrhea after you've had your gallbladder out:

• Go easy on the fat. Avoid high-fat foods, fried and greasy foods, and fatty sauces and gravies for at least a week after surgery. Instead, choose fat-free or low-fat foods. Low-fat foods are those with no more than 3 grams of fat a serving. Check labels and follow the serving size listed.
• Increase the fiber in your diet. This can help normalize bowel movements. Add soluble fiber, such as oats and barley, to your diet. But be sure to increase the amount of fiber slowly, such as over several weeks, because too much fiber at first can make gas and cramping worse.
• Eat smaller, more-frequent meals. This may ensure a better mix with available bile. A healthy meal should include small amounts of lean protein, such as poultry, fish or fat-free dairy, along with vegetables, fruits and whole grains.

You may also try limiting foods that tend to worsen diarrhea, including:

• Caffeine
• Dairy products
• Very sweet foods

Talk with your doctor if your diarrhea doesn't gradually go away or becomes more severe, or if you lose weight and become weak. Your doctor may recommend medicines, such as loperamide (Imodium A-D), which slows down intestinal movement, or medications that decrease the laxative effect of bile, such as cholestyramine (Prevalite). Your doctor may also suggest that you take a multivitamin to compensate for malabsorption of fat-soluble vitamins.

Some complementary and alternative medicine (CAM) practitioners blame common symptoms such as fatigue, headache and poor memory on overgrowth of the fungus-like organism Candida albicans in the intestines, sometimes called "yeast syndrome."

To cure the syndrome, they recommend a candida cleanse diet. The diet eliminates sugar, white flour, yeast and cheese, based on the theory that these foods promote candida overgrowth.

It's considered normal to find candida in the human gut (gastrointestinal tract), but an overgrowth of candida can exacerbate existing gastrointestinal diseases such as ulcerative colitis and Crohn's disease.

However, there is little evidence that dietary changes can improve the effects of a yeast overgrowth if you have these conditions. Doctors usually prescribe antifungal medications to treat yeast overgrowth, which is diagnosed by putting a small scope into your stomach (endoscopy) and taking a tiny sample of your stomach lining (biopsy).

Unfortunately, there isn't much evidence to support the diagnosis of yeast syndrome. And there are no clinical trials that document the efficacy of a candida cleanse diet for treating any recognized medical condition.

Not surprisingly, many people note improvement in various symptoms when following this diet. If you stop eating sugar and white flour, you'll generally wind up cutting out most processed foods, which tend to be higher in calories and lower in nutritive value.

Within a few weeks of replacing processed foods with fresh ones and white flour with whole grains, you may start to feel better in general. That, rather than stopping the growth of yeast in the gastrointestinal tract, is probably the main benefit of a candida cleanse diet.

Some people with MS wonder if cannabis could help relieve their symptoms. More than half of those with the disease say they'd consider trying it if it was legal and there was more scientific data available.

Studies on the use of cannabis and multiple sclerosis (MS) symptoms tell us this:

• Cannabis extract taken in a capsule form can help relieve muscle stiffness (spasticity) and spasms.
• The extract may reduce pain.
• A mouth spray form possibly reduces spasticity, pain and bladder urgency.

But the use of cannabis to treat MS symptoms is complicated.

All cannabis-based medicines have side effects. Some can be serious, such as:

• Difficulty with attention or concentration
• Dizziness or faintness
• Dry mouth
• Hallucinations
• Loss of balance and falls
• Depression or psychosis

Cannabis is a federally controlled substance in the United States. Medical marijuana and cannabis programs are legal in more than half of the country.

To date, the Food and Drug Administration has approved two synthetic forms of marijuana for medical use: dronabinol (Marinol) and nabilone (Cesamet). They are capsules that you take by mouth.

Both drugs are approved for treating chemotherapy-related nausea and vomiting that does not get better with standard treatment. Dronabinol is also approved for people with AIDS who have loss of appetite with weight loss. At this time, the drugs are not approved for other uses.

A cannabis extract mouth spray, nabiximols (Sativex), is not currently available in the U.S. Also, smoked marijuana has not been adequately studied for safety and benefit.

The role of cannabis for MS symptoms isn’t fully clear. Future research will help determine more about cannabis' benefits and risks, and compare its effects to other therapies used to treat spasticity, pain and other MS symptoms.

Not necessarily. Fresh foods generally have a higher nutrient content than do cooked or canned foods. But in this case, both fresh pumpkin and canned pumpkin are packed with nutrients, such as potassium, vitamin A and iron.

If you want to use fresh pumpkin, look for pumpkins without blemishes that are firm and heavy for their size. Whole pumpkins can be stored in a cool dark place for up to two months. If you use fresh pumpkin for bread, soup, pie or other recipes, don't throw away the seeds. You can bake them for a wholesome, crispy snack.

If you're looking for convenience, canned pumpkin without salt is a healthy alternative. Just check the Nutrition Facts label on the can so that you know what you're getting. Canned pumpkin products may be labeled as "pumpkin," "100 percent pumpkin" or "pumpkin pie mix." Canned pumpkin pie mix — which some recipes call for — usually contains added sugar and is therefore higher in calories than regular canned pumpkin. Try using regular pumpkin and reducing the amount of sugar the recipe calls for.

Health concerns about canola oil are unfounded. Canola oil, which is extracted from the seeds of the canola plant, is generally recognized as safe by the Food and Drug Administration.

Misinformation about canola oil may stem from the fact that the canola plant was developed through crossbreeding with the rapeseed plant. Rapeseed oil contains very high levels of erucic acid, a compound that in large amounts can be toxic to humans. Canola oil, however, contains very low levels of erucic acid.

Canola oil is also low in saturated fat and has a high proportion of monounsaturated fat, which makes it a healthy and safe choice when it comes to cooking oils.

Car sickness is a type of motion sickness. Motion sickness occurs when the brain receives conflicting information from the inner ears, eyes, and nerves in the joints and muscles.

Imagine a young child sitting low in the back seat of a car without being able to see out the window — or an older child reading a book in the car. The child's inner ear will sense motion, but his or her eyes and body won't. The result might be an upset stomach, cold sweat, fatigue, loss of appetite or vomiting.

It's not clear why car sickness affects some children more than others. While the problem doesn't seem to affect most infants and toddlers, children ages 2 to 12 are particularly susceptible.

To prevent car sickness in children, you might try the following strategies:

• Reduce sensory input. Encourage your child to look at things outside the car rather than focusing on books, games or movies. If your child naps, traveling during nap time might help.
• Carefully plan pre-trip meals. Don't give your child spicy or greasy foods or a large meal immediately before or during car travel. If your travel time will be short, skip food entirely. If the trip will be long or your child needs to eat, give him or her a small, bland snack — such as dry crackers and a small drink — before it's time to go.
• Try ginger candies. Hard ginger candy reportedly provides some relief from nausea associated with motion sickness, although research has not demonstrated a clear benefit.
• Provide air ventilation. Adequate air ventilation might help prevent car sickness. Try to keep the air clear of any strong odors, too.
• Offer distractions. If your child is prone to car sickness, try distracting him or her during car trips by talking, listening to music or singing songs.
• Use medication. If you're planning a long car trip, ask your child's doctor about an over-the-counter medication to prevent car sickness. Dimenhydrinate (Dramamine) is approved for kids 2 and older. The antihistamine diphenhydramine (Benadryl), approved for kids 6 and older, may also prevent symptoms. Both medications work best if taken about an hour before traveling. Read the product label carefully to determine the correct dose and be prepared for possible side effects, such as drowsiness. Nondrowsy antihistamines don't appear to be effective at treating motion sickness.

If your child starts to develop car sickness, stop the car as soon as possible and let your child get out and walk around — or have your child lie on his or her back for a few minutes with closed eyes. Placing a cool cloth on your child's forehead also might help.

If these tips don't help or if your child's car sickness makes travel difficult, talk to your child's doctor about other options.

Cardiac asthma is not a form of asthma. It's a type of coughing or wheezing that occurs with left heart failure. Depending on how severe your symptoms are, this wheezing can be a medical emergency.

Heart failure can cause fluid to build up in your lungs (pulmonary edema) and in and around your airways. The latter causes signs and symptoms — such as shortness of breath, coughing and wheezing — that may mimic asthma.

True asthma is a chronic condition caused by inflammation of the airways, which can narrow them, leading to breathing difficulties. True asthma has nothing to do with fluid in the lungs or heart disease.

The distinction is important because treatments for asthma and heart failure are different. Treatments for heart failure can help improve your symptoms for both the heart failure and the cardiac asthma. Overusing treatments for true asthma, such as rescue inhalers, could be dangerous and lead to a worsening of symptoms.

Family members often struggle with how to support a loved one who has diabetes. Here are some tips:

• Educate yourself. Learn everything you can about diabetes and your loved one's situation. Tag along to diabetes education classes and diabetes appointments if your loved one agrees. Don't offer unsolicited advice.
• Walk the walk. Join your loved one in making healthy lifestyle changes. Make changes together as a team or household. Set small goals such as taking a walk after dinner or trying a new healthy recipe. Don't play the food or exercise police.
• Be patient. Allow your loved one time to process what can be an overwhelming amount of information and recommendations. Be patient with the extra time your loved one may need to read labels, count carbohydrates, monitor blood glucose, administer insulin, perform foot care or pack for a trip. Don't disregard the fact that managing diabetes is hard work.
• Communicate your support. Ask your loved one how you can be helpful. Be specific about what you're able to help with. If your offer is refused, let your loved one know the door is open if and when they're ready. Don't offer help you're not willing to provide.
• Take care of yourself. Recognize your limitations. No one can be helpful if they're exhausted or overly stressed. Look for a support group for caregivers.
