Dave from Ferndale emails asking about HDL-good cholesterol. What are the benefits of keeping his good cholesterol high?
Well Dave - it could fight against Alzheimer's disease.
A new study found high levels of HDL-the good cholesterol-appears to help preserve mental function in older people. Now, it's just the opposite if you have high levels of LDL-the bad cholesterol.
Scientists learned some damage from Alzheimer's comes from deposits of sticky protein in vital areas of the brain. They found people with high levels of LDL - or bad cholesterol - have more of these proteins and have an increased risk of developing Alzheimer's.
To keep your cholesterol in check you should avoid saturated and trans fat foods. Make sure you fill your plate with lean meats, fruits and vegetables.
Nancy from Howell emails saying she doesn't seem to have any energy. Is there anything she can do?
Fatigue is one of the most common reasons adults head to the doctor. Numerous studies found people who go to the doctor complaining of fatigue have suffered with it for a while, anywhere from six months to several years.
First, eat a well balanced diet including protein, fruits, vegetables and whole grains. Make sure you're drinking enough water. 75 Percent of most americans suffer with dehydration. This can lead to depression, mood swings and fatigue. You should drink 8 glasses a day.
You also need to exercise! even if you feel too tired-get up and get moving-it's one of the best ways to fight fatigue.
Jan from Sylvan Lake says she worries all the time, to the point where it's overtaking her life. What can she do?
Excessive worry can be a serious problem and can lead to physical illness.
Researchers found when worry escalades it can cause fatigue, headaches, stomach aches and other pains. Some studies even found excessive worry can lead to cardiovascular problems. So what can you do? Talking to friends, relatives and coworkers about what worries you can help. As well as getting enough rest and staying physically active. Exercise keeps the brain busy so it doesn't have time to worry.
Studies also found relaxation techniques, such as breathing exercises, can help some people with general anxiety disorder.
Penny from waterford emails asking about mercury levels in fish- do the health risks outweigh the benefits.
A recent study by the institute of medicine and harvard school of public health found the levels of pollutants in fish are below what the food and drug administration would consider *unsafe*. The study also determined eating fish is worth any "minimal" risk the contaminants may cause.
Fish is packed with Omega 3 fats which can protect against heart disease. Experts suggest eating two 3 ounce servings of fish a week.
This does not apply to pregnant women or nursing mothers. They should steer clear of certain types of fish like king mackerel, tilefish, shark and swordfish. But it is recommended to add 12 ounces of other types of fish to your diet to make sure you're getting the health benefits.
Andrew from Detroit says his vision isn't what it used to be. Is he losing his sight as he gets older?
Unfortunately it is possible.
Almost 1 million Americans over age 40 are considered legally blind. Another 2.4 Million have significantly reduced vision. The four eye disorders that pose the greatest risk of vision problems as you age are cataract, glaucoma, age related macular degeneration and diabetic retinopathy.
But you may be able to help yourself. A new study found people with diabetes who kept their blood sugar at near normal levels cut their risk of developing eye disease by 75 percent. Exercise and proper nutrition is also key! studies found fruits, vegetables and fish are full of nutrients that are good for your eyes.
