Chocolate And Brain Health

Published

on

Cocoa, especially if it is minimally processed, contains high levels of health enhancing antioxidant flavnols – a distinct group of naturally occurring compounds that can be found in a variety of foods such as tea and red wine.
Now a recent study has shown how this protection can extend to the brain.
It is normal for cognitive function to slightly deteriorate with age. Memory capacity begins to worsen, along with processing speed and the ability to form long-term memories. This decline is different from the cognitive decline that signals possible dementia. Finding a way to slow it down is becoming increasingly important as our population ages.
While previous studies have demonstrated the benefits of cocoa flavanols for people suffering from mild cognitive impairment, the current study focused on healthy people experiencing the usual mental wear and tear that comes with older age.
The researchers, from Italy’s University of L’Aquila and chocolate company Mars enrolled men and women aged 61-85 years with no evidence of cognitive dysfunction, the participants in this controlled, randomized, double-blind study were assigned to one of three groups and given a cocoa drink to consume for  daily for 8 weeks.
The drinks were nutritionally matched except for their flavanol content which was either high (993 mg), intermediate (520 mg) or low (48 mg).
Significant improvements
The high- and intermediate-flavanol cocoa drinks were produced using Mars’ Cocoapro® a specially prepared, though not commercially available, flavanol-rich powder, while the low-flavanol drink was made with a highly processed, alkalized cocoa powder that you might find in everyday cocoa products.
Other than the inclusion of the test drink, normal diets and regular lifestyle were maintained throughout the study.
At the start of the study and again after eight weeks, cognitive function was assessed using a battery of tests that examined memory, retention, recall, as well as executive function. Among those individuals who regularly consumed either the high- or intermediate-flavanol drinks, there were significant improvements in overall cognitive function after only eight weeks.
The volunteers who drank either the high- or medium-flavanol drinks showed significant improvements in their overall cognitive function after only eight weeks. Plus, the group showed reduced blood pressure and improved insulin resistance. The researchers believe these positive results may be due, in part, to improved vascular function.
Study shows that even cognitively healthy individuals can quickly benefit from the regular inclusion of cocoa flavanols in their diets.
In addition to evaluating cognitive function, the researchers also monitored insulin resistance, blood pressure and other metabolic markers. Excitingly, there was also evidence of improvements in these cardiometabolic outcomes.
In the high- and intermediate-flavanol groups, both systolic and diastolic blood pressures were reduced and insulin resistance was significantly improved. In contrast, only a modest improvement in diastolic blood pressure was observed in the low-flavanol group, with no significant improvements in either systolic blood pressure or insulin resistance among the consumers of the low-flavanol drink.
It is not yet fully understood how cocoa flavanols bring about improvements in cognitive function, but the study’s authors suggest that the improvements in insulin resistance and blood pressure could be revealing.
“Earlier studies suggest a central role for insulin resistance in brain aging,” said Dr. Giovambattista Desideri, lead author on the paper. “These results could therefore provide some insight into a possible mechanism of action for the cognitive improvements we have observed.”

Getting Trimmed Naturally

Published

on

There are a lot of misconceptions about weight gain.
The first is that weight gain comes from extra calories we do consume that we do not expend. Experts say we eat too much and exercise little. So if one get fatter, then, surely he or she must be eating too much.
The other misconception is that once we cut our food, then, we will naturally become trimmed. All these are hinged on the diet theory, which only works for some time.
Over the past 40 years, studies have shown that you can not get clinically significant effect from cutting down on your calories. Even though experts are saying that sloth is responsible for weight gain- they overlook one basic truth that dieting only works for a short period.
The new study that seems to break those myths about body fat is now revealing some stunning facts. The kind of food we eat makes us fat. Two scientists at University of Pennsylvania, Mitchell Lazar and Cardiologist Allan Sniderman at McGill University, all in the United States have shown that food that we eat often makes us pack in flesh. These include bread, plain baked potatoes, and plain pasta, rice, sweet corn. They confirmed that fatty foods are not the enemy but easily digested carbohydrates, while steak, burgers, cheese or sour cream help us lose weight and keep our heart healthy.
This sounds ironical, but it has been discovered that those who do diet and avoid those foods end up getting hungry. What happens is that when you conserve energy or burn less energy, you are bound to add more flesh. Many public health authorities want us to practise energy balance, which is a new way to say that you should not take more calories than one expends.
No matter how one counts what he or she eats, it is impossible to determine calories and know when we are over board. No matter how good you are at counting calories, you can’t do it. So its couple of sips of soft drinks and few bites of humburger that can make you add weight. That means it at the point when we eat extra than the body want that the body store excess as fat.
The myth of exercising to reduce weight is really making waves. Exercise is helpful but it is not the main ingredient for fat burning. The funny truth is that the two things we tell people to do in order to lose weight-eat less and exercise more- are the exact two things that make one more hungry. Thus, there is need for balance. If one must exercise, then it should be done moderately so as to allow the body to recover the strenght.
The reality is that insulin is the primary hormone that makes one to add weight, especially one eats food that spikes insulin like bread, biscuits, sweets, soft drinks. It is refined carbohydrates that raise insulin levels in the body. Explained in simple terms, your fat tissue is more like your wallet, and your meals are like going to the ATM. You know how you use the ATM: You put the cash in your wallet and gradually spend it, and when you get too low on cash, you go back to the ATM. It is the insulin that locks the money in your wallet, so you keep going to the ATM, and your fat cells are getting fatter and fatter. More often, you become hungry and you eat again because the insulin can not get at the fatty acids leading to weight gain.
Low carb diet is key if you are to get trimmed. In Africa where stables are more of carbohydrate it is best to choose those with fibre. It is difficult to follow the Atkins diet like eating skinless chicken and green salad, melted mozzarella cheese and all those western diet.
An example of a workable diet is to include eggs more often and cut down on processed foods, especially processed carbohydrate. Complex carbohydrate, and vegetables have more fibre and make you get filled quickly. Instead of Irish potato, go for sweet potatoes, oats that have more fibre. I advise people to eat garri than processed plantain and wheat meals. By the way, processed wheat can worsen the body ails.

Eye Expert Cautions On Rays From Electronics

Published

on

An optometrist, Dr. Matthew Daniels says many Nigerians are suffering from refractive eye problem which can be corrected.
Besides, he disclosed that most of the eye problems common these days come from rays from long use of electronic devices.
The one time Chairman of Business Development Committee of the Nigeria Optometery Association(NOA) explained that rays emitted from electronic devices such as phones, television, computers have effects on the eyes.
He urged for caution and toning down of light from phones and computers so as to reduce eye irritation and other eye maladies that may affect sight.
In a chat with The Tide, Dr. Daniels said the refractive eye error maybe long sight or short sight which can be corrected.
However, he decried that most Nigerians do not take the health of their sight seriously and as such, suffer from eye defects which could have been treated without much expenses.
Commenting on the planned program me by the Federal Government to provide eye glasses to Nigerians, Dr Daniels observed that it may be difficult to provide free eye glasses to five million Nigerians.
For him, what the people need is more eye clinics and hospitals at the grassroots, as he lamented that most eye sight challenges are common in the rural areas.

WHO Raises Alarm Over Increased Incidence Of TB, Others

Published

on

The World Health Organisation(WHO) has raised alarm over increased incidence of tuberculosis, HIV and malaria as it charged member countries to make health an urgent matter of  policy focus.
Dr. Tedros Adhanom Ghebreyesus, WHO Director-General made the charge at the 78th session of the United Nations General Assembly (UNGA 78) in New York stressing need to put health for all on the highest political agenda.
WHO’s DG appeal comes as the world faces multiple humanitarian and climate-related crises which are threatening lives and livelihoods around the world.
The world health  apex body observed that progress in reducing infant and maternal mortality has stagnated (in some regions, while progress in tackling infectious diseases like HIV/AIDS, tuberculosis (TB) and malaria has also declined.
It noted that many parts of the world are also witnessing rollbacks in sexual and reproductive health and rights, as
access to life-saving tools is becoming uneven across the world, with millions unable to afford or obtain needed care.
In addition it said  no communicable diseases and mental disorders, which account for over 70% of deaths globally, threaten social and economic development across the world.
“Ill health robs individuals, families, communities and entire nations of opportunities to grow and flourish,” Dr Tedros said.
The body decried  that billions of people cannot access or afford essential health services and as such are exposed to poverty, abd other preventable and treatable diseases like TB.
WHO’s call to accelerate the achievement of health targets comes ahead of the Sustainable Development Goals Summit (SDG Summit) and an unprecedented number of health-focused high-level meetings at UNGA, aimed at strengthening pandemic prevention, preparedness, and response, delivering universal health coverage (UHC) and ending TB.
As government leaders gather to make commitments around three major health issues, they have a chance to demonstrate that health is an investment, not a cost, and is fundamental to thriving, resilient families, societies and economies.
“If COVID-19 taught us nothing else, it’s that when health is at risk, everything is at risk,” WHO DG said .
Recalling the effect of the Covid19 pandemic, he lamented the  enormous economic, social and political upheaval, and effect on progress towards the health-related targets in the Sustainable Development Goals.
