New York, Nov 18: A computer brain training exercise designed to improve the speed and accuracy of visual attention can help seniors reduce risk of dementia by nearly a third, suggest results of a 10-year study.
This exercise is known as “speed of processing training”, “useful field of view training”, or “UFOV training.
“Speed of processing computer brain training resulted in decreased risk of dementia across the 10-year period of, on average, 29 per cent as compared to the control,” said lead study author Jerri Edwards from University of South Florida in the US.
“When we examined the dose-response, we found that those who trained more received more protective benefit,” Edwards added.
The study, published in the journal Alzheimer’s & Dementia: Translational Research & Clinical Interventions, enrolled 2,802 healthy older adults in the US and followed them as they aged from an average of 74 to 84 years.
Participants were divided into a control group or one of three intervention arms using different types of cognitive training.
One group received instruction on memory strategies and another group received instruction on reasoning strategies. The third group received individualised computerised speed of processing training.
Researchers found no significant difference in risk of dementia for the strategy-based memory or reasoning training groups, as compared to the control group.
However, as compared to the control group, the computerised speed training group showed significantly less risk of dementia — averaging a 29 per cent risk reduction.
When reviewing the impact of each computerised speed training session completed, researchers found those who completed more sessions had lower risk.
The computerised speed training task or the computer brain training exercise was designed to improve the speed and accuracy of visual attention, including both divided and selective attention exercises.
The computer brain training exercise was developed by Karlene Ball of the University of Alabama Birmingham and Dan Roenker of Western Kentucky University – both in the US. (IANS)
People who drink three to four cups of coffee a day are more likely to see health benefits than harm, experiencing lower risks of premature death and heart disease than those who abstain, scientists said on Wednesday.
The research, which collated evidence from more than 200 previous studies, also found coffee consumption was linked to lower risks of diabetes, liver disease, dementia and some cancers.
Three or four cups a day confer the greatest benefit, the scientists said, except for women who are pregnant or who have a higher risk of suffering fractures.
Coffee is one of the most commonly consumed drinks worldwide. To better understand its effects on health, Robin Poole, a public health specialist at Britain’s University of Southampton, led a research team in an “umbrella review” of 201 studies based on observational research and 17 studies based on clinical trials across all countries and all settings.
“Umbrella reviews” synthesize previous pooled analyses to give a clearer summary of diverse research on a particular topic.
“Coffee drinking appears safe within usual patterns of consumption,” Pool’s team concluded in their research, published in the BMJ British medical journal late on Wednesday.
Drinking coffee was consistently linked with a lower risk of death from all causes and from heart disease. The largest reduction in relative risk of premature death is seen in people consuming three cups a day, compared with non-coffee drinkers.
Drinking more than three cups a day was not linked to harm, but the beneficial effects were less pronounced.
Coffee was also associated with a lower risk of several cancers, including prostate, endometrial, skin and liver cancer, as well as type 2 diabetes, gallstones and gout, the researchers said. The greatest benefit was seen for liver conditions such as cirrhosis of the liver.
Poole’s team noted that because their review included mainly observational data, no firm conclusions could be drawn about cause and effect. But they said their findings support other recent reviews and studies of coffee intake. (VOA)
Researches assert that blood group affects our health and well-being
Blood Type Diet focuses on the consumption of specific foods that aid bodily functions
Staying active, regular exercise and the right food consumption are key to a healthy lifestyle
New Delhi, August 24, 2017 : Exhausted after meager activity? Are you tired of your dull face? Do you suffer from recurring diseases? Are you trying to lose weight? Do you want to adopt a healthier lifestyle? You can change your diet, or begin a new work out. But there is nothing that you can possibly do to change your blood type. Wondering what is the connection between a healthy life and your blood type?
Various studies assert that our blood group is the primary genetic factor that affects our health and well-being to a large extent.
If your friend is having troubles gaining weight, while you struggle to lose some of it despite a healthy diet and regular exercise, it may be because of your blood type. Alternatively, it also interacts with our immune system altering our risk for several common diseases. According to the blood type, mood swings and temperament of the person may also fluctuate and vary between individuals.
How Does Blood Type Affect Our Health And Body
Determines susceptibility to specific diseases
According to researches, people with certain blood groups are at a higher risk of some diseases. For example, individuals with blood type O are understood to be at a high risk of stomach ulcers but at a lower risk of heart diseases and blood type A is believed to have higher risk of microbial infections.
Reaction to stress
People with type O blood tend to overproduce adrenaline as a reaction to stress. Thus, they take longer to recompose following a stressful situation as they take a while to clear the adrenaline from their bodies.
Influence on gut bacteria
Different types gut bacteria are known to have been found in people of different blood types. For example, the micro-biome present in individuals with blood type A break down carbohydrates more efficiently than those with blood type O, who store carbs as fats in their bodies.
Food fads are just that, fads. They come and go. Not everybody has the same primary nutritional requirement.
Deepika Dua Arora, a Dietitian at Mutation Diet Clinic, Gurugram asserts the complementary relationship between one’s blood group and the nutritional aspect. According to her, the blood group diet allows us to keep in check our hereditary medical troubles like cholesterol, diabetes, hypertension, etc.
What Is Blood Type Diet?
The Blood Type Diet focuses on the consumption of specific foods that aid bodily functions like allow better digestion, increase the body’s energy level, prevent illnesses and diseases and additionally help lose weight.
Dietitians strictly stress the importance of Rh factor while planning diets.
Rhesus factor is a category of protein present on the surface of red blood cells (RBCs). Individuals with Rhesus factor are Rh positive while those who lack the compound are Rh negative.
Rh factor plays an important role in diets as individuals with Rh negative blood type are more prone to lgE allergies than Rh positive.
Rh negative reacts with multiple foods like nuts, beans eggs among other things, thus, their diets must be planned accordingly. Individuals with Rh negative blood groups should consume more starch like brown sugar, poha, wheat burger, etc.
Right Food For Your Blood Type
An important concept to understand is that not everybody has the same primary nutritional requirement. In addition to this, there are several nutrients that are not absorbed by specific blood groups. Together, this can give rise to serious health problems. Thus, it is recommended to have food that is complimentary to one’s blood type.
We provide you with a list of foods that are great for specific blood types,
Individuals with this blood type should consume more of wheat and roughage based vegetarian food- wheat bran, brown rice, brown poha, soya, besan chilla etc. They should avoid animal protein as it can prove to be unsuitable for them.
Blood Group: B
Green vegetables, Eggs, Low-fat dairy.
Individuals with this blood type should consume more milk products and animal proteins, however, wheat does not suit them much – paneer, eggs, fish, oat meal, and oat bran.
Consumption of wheat starches is not good for individuals with this blood type.
Blood Group: A
Banana, coconut, cashew, papaya, pistachios, beer
Individuals with this blood type should avoid animal foods- chicken, fish, eggs. Additionally, oats are also not good for them.
Blood Group: B
Corn, tomatoes, sesame seeds, peanuts
Individuals with this blood type should also avoid oats and animal foods- chicken, fish, eggs
Blood Group: AB
Whole milk, caffeine, alcohol, black tea, corn, coconut, mangoes, bananas
Individuals with this blood type must not starve themselves as the gap in between meals is not healthy for them.
4 Rules To A Healthier Life
Break the myth that one needs to have three meals in a day. Always have small, healthy meals throughout the day at regular intervals. This will manage insulin levels, keep hunger in check and supplement the body with a constant source of energy.
Do not confuse thirst with hunger. This can add a few extra, unnecessary calories which might be difficult to be digested and processed by the body.
Always read the label on food products. Calculate the calorie information provided to accommodate the product into your calorie allowance while on a weight loss schedule.
If you think only food is going to lead you to a healthier life, you need to think again. Staying active and regular exercise are key to a healthy lifestyle.

Regular physical has a positive impact on brain metabolism
The findings showed that physical activity prevented an increase in choline – a very important macro-nutrient
Magnetic resonance tomography (MRT) and magnetic resonance spectroscopy (MRS) were used to measure brain metabolism and brain structure
London, July 23, 2017: Regular physical exercise not only enhances fitness but also has a positive impact on brain metabolism, researchers say.
The findings showed that physical activity prevented an increase in choline — a macro-nutrient that’s important for liver function, normal brain development, nerve function, muscle movement, supporting energy levels and maintaining a healthy metabolism.
The concentration of this metabolite often rises as a result of the increased loss of nerve cells, which typically occurs in the case of Alzheimer’s disease, said Johannes Pantel, Professor at the Goethe University Frankfurt in Germany.
In the study, physical exercise led to stable cerebral choline concentrations in the training group, whereas choline levels increased in the control group.
The participants’ physical fitness also improved. They showed increased cardiac efficiency after the training period. Overall, these findings suggest that physical exercise not only improves physical fitness but also protects cells.
To understand the positive influence of physical activity on the brain, gerontologists and sports physicians examined the effects of regular exercise on brain metabolism and memory of participants aged between 65 and 85 on movement-related parameters, cardiopulmonary fitness and cognitive performance.
The participants were asked to mount an exercise bike three times a week over a period of 12 weeks for 30-minute training sessions.
Magnetic resonance tomography (MRT) and magnetic resonance spectroscopy (MRS) were used to measure brain metabolism and brain structure.
The results showed that regular physical exercise seems beneficial in the prevention of cognitive impairment and dementia in old age. (IANS)
