HIV Causes Premature Brain Aging

A new research is showing that people infected with the HIV virus have premature aging of the brain. The research has shown that blood flow in HIV patients is the same as uninfected people who are 15 to 20 years older. In the study, researchers used MRI scans to study blood flow in the brains of 26 people infected with HIV and 25 people who were not infected. The ages and the educational levels all of the individuals were similar. Researchers found reduced blood flow in the brains of younger people infected with HIV recently infected with HIV as well as the older patients. It is unclear whether this is caused by the virus, the medication to treat the disease, or both. Currently, 14 to 18 percent of all AIDS patients in the United States are over 50 years old and older generations have an increasing high rate of new infections. By 2015, more than half of all AIDS patients may be over 50 years old.

Improve Memory with Apples

It is found that eating apples could help to improve and prevent Alzheimer's disease. Eating two or three apples a day causes the levels of acetylcholine to increase. Acetylcholine is a neurotransmitter that is important to maintaining memory that decreases with age. Neurotransmitters are chemicals that are released from nerve cells that transmit messages to other nerve cells. Apples also have an antioxidant called quercetin, which has been proved in studies to help prevent Alzheimer's disease and it improves memory. Quercetin is found in the flesh and skin of an apple. The juice in apples may protect against oxidative damage that contributes to age-related disorders, such as Alzheimer's disease.

Stop a Heart Attack by Coughing

It is found that coughing deeply and vigorously can stop a heart attack from turning deadly. Properly timed and performed coughs could allow a heart attack victim to remain conscious and regain an effective heart beat. If you feel palpations or lightheaded, take deep breaths and cough repeatedly and very vigorously and hard several times. This could support your circulation for a while until help arrives. A deep breath should be taken before each cough and the cough must be deep and prolonged. A breath and a cough should be repeated every two seconds until help arrives or until the heart is beating normal again.

Coughing deeply would cause a pumping action that would cause blood to be pushed through the body and to the brain. Coughing also increases and decreased chest pressure, which can raise a slow heart rate, increase cardiac output, and sometimes stop an arrhythmia. Taking deep breaths get oxygen into the lungs and coughing causes the heart to squeeze and helps the the blood to circulate. The squeezing pressure on the heart also helps it to have a normal rhythm.

Ease Stress with Scents

It is found that the scents of lavender, lemon, orange, grape, mango, and basil are good at easing stress. They all contain linalool, which is a chemical that can offset the effects of stress. Linalool has a calming effect on the limbic center of the brain, which is involved in processing emotions.

Lavender is a good scent that is good at aiding relaxation and reducing anxiety. Lavender oil can be used to treat pain from tension headache when it is breathed in as a vapor or diluted and rubbed on the skin. When it is added to a vaporizer, it can help to treat cough and respiratory infection. The scent of lemon has shown in studies to enhance mood and ease stress and depression. Basil can help to ease depression and relieve headaches and migraines.

Aid Weight Loss with Calcium

Calcium is found to be good at helping weight loss. It is good at reducing hunger and studies have shown that calcium stored in fat cells in the body play an important role in regulating how fat is stored and broken down by the body. More calcium in a fat cells means more fat will be burned. It is also assumed that when a person is calcium deficient, the brain detects this and compensates by telling your body that it needs food, which works against someone who is trying to lose weight. A research found that when women who were calcium-deficient took a supplement, they lost 4 times more weight than women who didn't take a calcium supplement. Foods that are rich in calcium include low-fat yogurt, milk, beans, and dark leafy greens.

How to Stop Onions From Making You Cry

There are simple ways that you can stop from tearing up when you are around onions. The tearing up mechanism happens because when you cut into an onion, its cells rupture and releases enzymes that produce a gas called propanethial sulfoxide. When the gas reaches your eyes, it reacts with tears to produce a mild sulfuric acid. The brain signals the eyes' tear glands to produce more liquid to flush it out. The more that onions are chopped, the more your eyes tear up.

It is a good idea to chill an onion in the freezer before cutting it because cold temperatures can slow down the release of enzymes. You can also pour a tablespoon of vinegar onto the cutting board. The acid in the vinegar stops the chemical reaction of the sulfur in the onion and causes a reduction in tears. It is another good idea to put an onion under water before chopping it. The water would absorb the onion's gas.

Ignite the Body's Weight Loss Hormone

There is a hormone called leptin in the body that can suppress hunger. It is produced in the fat cells of the body and it travels to the brain after a meal to tell the body that you are full and don't need to eat anymore. When the meal is digested, leptin levels decrease and you gain an appetite again. There are things that you can do to help leptin levels and reduce hunger.

It is a good idea to eat foods that are low in triglycerides. Triglycerides are negative in the fact that it prevents leptin from reaching the brain. Studies have found that foods higher in carbohydrates and lower in fat can raise leptin levels.

It is also a good idea to sleep 8 hours each day and exercise regularly. Sleeping less than 8 hours lowers leptin levels in the blood and brain. Regular exercise lowers triglyceride levels and helps the brain to absorb more leptin.

Fight Cancer with Fruits

Citrus fruits, such as oranges, tangerines, lemons, and grapefruit, contain flavonoids, which are anti inflammatory compounds that stimulate the detoxification of carcinogens by the liver. There are certain flavonoids in the skin of tangerines that promote the death of brain cancer cells. In some fruits there are compounds that give them their dark color and contain powerful cancer fighting properties. Citrus fruits have been shown in studies to reduce the risk of developing certain types of cancer in the digestive system, such as the esophagus, mouth, and stomach. They also have anticancer molecules that affect the growth of cancer cells.

Scientists Developing Foods To Help You Lose Weight

At the Institute of Food Research in Norwich, England, foods are being developed that would help a person lose weight by slowing down the digestive system and triggering a signal to the brain to suppress appetite. It would control appetite by tricking the brain into thinking that you have eaten too much when you actually haven’t. The products could possibly be sold on the market in a few years.

Scientists at the University of Newcastle are testing a seaweed extract called alginate that would reduce fat absorption by cutting the level of glucose that is digested by the body before it is broken down in the large intestine. In taste testings done with several dozen people, it is found that most people felt that the foods enhanced by alginate tasted as good or even better.

Scientists in North America and Europe are developing products to control appetite, such as chemical injections and implantable devices that would interfere with the digestive system. It is not certain if appetite controlling foods could cure all cases of obesity.

The Health Benefits of Omega-3s

Omega-3s are a family of unsaturated fatty acids that are important for good health but are not naturally made by the body. They are mostly found in fish and offer good healthy benefits for the heart, eyes, joints, and brain.

Omega-3s have been found to reduce the rate of fatal and nonfatal heart attacks and can slightly lower blood pressure levels. It can reduce heart attacks by reducing inflammation and blood clots. It also slows the buildup of plaque in the arteries that can cause a heart attack. It can lower blood pressure by making it possible for blood to flow better in the veins through the reduction of plaque buildup.

Omega-3s can protect against the development and progression of retinopathy, which is the deterioration of the retina. DHA is in the omega-3 group and it is used by the photoreceptor cells of the retina in the eye. Not getting enough omega-3s in your diet can cause vision problems.

When it comes to the joints, omega-3s can improve morning stiffness and joint pain related to rheumatoid arthritis and reduce inflammation in the joints.

Omega-3s have an effect on the brain because they can increase the grey matter in the brain that is related to mood and behavior. This could help depression and improve mood and emotions.

Cell Phones Bad For Kids

There have already been links between cell phone use and brain cancer. The microwave radiation that is emitted from cell phones can affect a child's brain worse than an adult because younger skulls are thinner and less protective. The worse effects come from long term and frequent use of using wireless phones. Radiation levels vary by phone and wireless phones are assigned a number called the Specific Absorption Rate (SAR). It is recommended to choose a cell phone with a lower SAR rating.

The risks of tumor growth and damage decreases as a wireless phone is moved farther from the face. It is recommended that anyone using a wireless phone should use a headset or a wireless Bluetooth device.

Good Ways to Ease Stress and Fatigue

Stress can trigger a surge in hormones, such as cortisol and adrenaline, which can cause fatigue, headaches, or back pain. There are foods and drinks that can be used to ease stress.

Carbohydrates are good at easing stress. They can boost the levels of serotonin in the brain and make you feel calmer. Serotonin is a chemical that controls the stress management system in the brain.

Dark chocolate contains high levels of caffeine and theobromine, which can improve mood and energy levels. Chocolate can have an affect on the levels of endorphins released into the brain that can ease pain and stress. It also contains tryptophan, which is a chemical that causes the release of serotonin.

It is found that combining caffeine and the amino acid L-theanine, both which are present in tea, can decrease mental fatigue and improve alertness, reaction time, and memory. Black tea can help to ease stress by lowering the stress hormone cortisol.

Use Blueberries to Help Memory

Eating at least a cup of blueberries each day can improve your memory in just a matter of weeks. Blueberries, blackberries, cranberries, and cherries contain flavonoids, which are compounds that are contributed to the growth of brain cells. Blueberries are also phytochemical rich so that they are good at reversing age-related memory problems. They also have an effect on neurons by enhancing neuronal connections in the brain to improve cellular communications and stimulate neuronal regeneration.

Celery For a Healthy Mind

t is found that eating celery and bell peppers can help keep your brain healthy. They both contain a plant compound called luteolin than can prevent inflammation in the brain that is connected to aging and other diseases, such as Alzheimer's and multiple sclerosis. Celery also has compounds that can fight Alzheimer's and other degenerative diseases.

Why Fish Oil Is Healthy For You

Fish oil products are healthy because they contain the Omega-3 fatty acids DHA and EPA, which can lower blood pressure, prevent arrhythmias, reduce inflammation, grow new brain cells, improve memory, and improve brain function. There hasn’t been a daily value set but it is recommended to consume 1,000 mg of DHA and EPA combined per day.

Scientist Find Possible Alzheimer’s Gene

There are scientists that have found a gene that might raise the chances of getting the most common kind of Alzheimer’s disease by 45 percent in people who inherit a certain form of the disease. The gene affects a brain cell’s ability to take in calcium. Hopefully, drugs can be made to fight this effect. Most people are over the age of 65 that are affected by the disease.

Only one gene, called CALHM1, has been found to affect the risks associated with people over the age of 65. There are many other genes that are being studied as having the possibility to affect the disease.

Common Causes of Strokes

Most strokes happen when clot blocks blood flow to the brain. Strokes can also happen when a blood vessel bursts in the brain. High blood pressure encourages strokes because it can cause a buildup of arterial plaque, which can cause blood clots.

Birth control pills and hormone therapy increases the risk of having a stroke. Hormone therapy for menopause symptoms has less estrogen than birth control pills but still increases the risk of stroke a little bit.

Sleep apnea is a condition that interrupts the breathing process while a person is asleep. It raises blood pressure and the risk of having a stroke.

Other things that increase the risk of stroke include blood clotting disorders and having migraines with auras. Auras are visual changes that happen before having a migraine.

The risk of having a stroke can be cut in half just by lowering high blood pressure and high cholesterol. If a female has high cholesterol, hypertension, obesity, or diabetes, then she should be very cautions when taking birth control pills so that she can lower the risk of having a stroke.

Ways to Prevent Memory Loss

Memory loss usually starts at 16 years old and it is a common problem for people by the age of 40. There are things that can be done to prevent it.

Regular exercise can help to prevent the arterial aging that plays a part in memory loss. Exercise uses concentration and coordination, which are two things that require the use of brain neurons and keep them active.

There are some nutrients that fight memory loss. Omega-3 fatty acids help to keep the arteries clear and improve the process of message-sending brain neurotransmitters. They are found in fatty fish, such as salmon and mahimahi. It is recommended to eat 13 ounces of fish each week or take two grams of fish oil supplements, DHA, each day.

How Hormones Affect Food Cravings

It is found that how tempting food may seem could depend on a person’s level of the hormone leptin. Weight is not only controlled by calorie intake and exercise, but also by complex brain complexes. Someday, scientists might be able to develop weight-loss drugs that modify the brain’s reaction to food.

Body Dysmorphic Disorder

People who have body dysmorphic disorder (BDD) believe that at least one part of their appearance is very unattractive, even after cosmetic surgery. Researchers have found that people with BDD process visual information differently that most other people do and rely more on the analytical left side of the brain. Their brain also focuses on details without putting them into the context of the whole face, which can lead to a distorted self image. BDD can be biological and genetic so that it is not just caused because of society’s obsession on appearance.
