This Nutrient Balance Reverses Brain Aging

The right balance between omega-3 and omega-6 fatty acids may help promote healthy cognitive aging, new research finds.

While we are used to hearing about the benefits of the fatty acids in fish and fish oils, that is only half the story.

Omega-6 fatty acids can come from nuts, seeds and other oils.

Typically, Western diets have too much omega-6 and not enough omega-3.

Together, a balance of these fatty acids may help to reduce age-related decline and maintain the integrity of cortical structures.

Ms Marta Zamroziewicz, who led the research, said:

“We studied a primary network of the brain — the frontoparietal network — that plays an important role in fluid intelligence and also declines early, even in healthy aging.
In a separate study, we examined the white matter structure of the fornix, a group of nerve fibers at the center of the brain that is important for memory.”

The researchers examined the levels of polyunsaturated fatty acids in adults aged 65 to 75, along with their brain structure.

The best balance of fatty acids for brain health.

Ms Zamroziewicz explained that it takes more than just fish and fish oils to keep the brain healthy with age:

“A lot of research tells us that people need to be eating fish and fish oil to get neuroprotective effects from these particular fats, but this new finding suggests that even the fats that we get from nuts, seeds and oils can also make a difference in the brain.”

A second study found a link between a balanced amount of omega-3 and omega-6 fatty acids and greater memory preservation in older adults.

Ms Zamroziewicz explained:

“These findings have important implications for the Western diet, which tends to be misbalanced with high amounts of omega-6 fatty acids and low amounts of omega-3 fatty acids.”

Professor Aron Barbey, who co-authored the study, said:

“These two studies highlight the importance of investigating the effects of groups of nutrients together, rather than focusing on one at a time.
They suggest that different patterns of polyunsaturated fats promote specific aspects of cognition by strengthening the underlying neural circuits that are vulnerable to disease and age-related decline.”

The study was published in the journal Nutritional Neuroscience (Zamroziewicz et al., 2017).

Higher IQ Linked To This Type of Fitness

Study of 1.2 million people finds links between fitness and verbal comprehension and logical thinking skills.

Young adults who are fitter have a higher IQ and are more likely to go on to higher education, research finds.

Higher IQ is linked to a higher heart and lung capacity, not to muscular strength.

Heart and lung capacity was most strongly linked to verbal comprehension and logical thinking skills.

Professor Michael Nilsson, one of the study’s authors, said:

 “Being fit means that you also have good heart and lung capacity and that your brain gets plenty of oxygen.
This may be one of the reasons why we can see a clear link with fitness, but not with muscular strength.
We are also seeing that there are growth factors that are important.”

The researchers found that the link is down to environmental factors, not genes.

In other words, it could be possible to increase your IQ by getting fitter.

Dr Maria Åberg, the study’s first author, said:

“We have also shown that those youngsters who improve their physical fitness between the ages of 15 and 18 increase their cognitive performance.
This being the case, physical education is a subject that has an important place in schools, and is an absolute must if we want to do well in maths and other theoretical subjects.”

The conclusions come from a study of 1.2 million Swedish men doing their military service, who were born between 1950 and 1976.

How Your Smartphone Can Make You Smarter

Researchers tested how the mere presence of a smartphone affected cognitive capacity.

The mere presence of your smartphone makes you more dumb, even when it is on silent, new research finds.

It doesn’t even matter if it is turned off!

So, leaving your smartphone in another room actually makes you smarter.

The study found that when people had their smartphones with them, their cognitive capacity was reduced.

Cognitive capacity is the ability to hold and process information in the mind.

Dr Adrian Ward, the study’s first author, said:

“We see a linear trend that suggests that as the smartphone becomes more noticeable, participants’ available cognitive capacity decreases.
Your conscious mind isn’t thinking about your smartphone, but that process — the process of requiring yourself to not think about something — uses up some of your limited cognitive resources.
It’s a brain drain.”

People who left their smartphones in another room performed the best on cognitive tests, the study found.

The researchers tried all sorts of variations to check the effects.

Some people had their smartphones:

  • face up,
  • face down,
  • turned on,
  • and turned off.

It didn’t matter, as long as the smartphone was near them, it decreased their brain power.

The only way to get rid of the smartphone disadvantage was put it in your pocket or, better yet, to put it in another room.

Dr Ward said:

“It’s not that participants were distracted because they were getting notifications on their phones.
The mere presence of their smartphone was enough to reduce their cognitive capacity.”

The researchers also tested how dependent people were on their phones.

How strongly, they were asked, did they feel they needed their smartphone to get through a typical day?

The researchers found that the most dependent people were the most put off when their phone was in the same room with them.

Once it was totally out of the room, then it didn’t have the same negative effect.

 
The study was published in the Journal of the Association for Consumer Research (Ward et al., 2017).

Five Foods That May Increase Your IQ

A healthy diet as you’re growing up may help you have a higher IQ, while a diet high in processed foods, fat and sugar may result in a lower IQ, according to a study published in the Journal of Epidemiology & Community Health in February 2011. Many of the same foods typically recommended for a healthy diet may also be good for your IQ.

Fish and Omega-3 Sources

Omega-3 fats, found in many types of fish and seafood, walnuts and flaxseeds, are important for infant brain development. An article published on the Association for Psychological Science website notes that children given omega-3 fats have higher IQs than those who don’t consume much of these essential polyunsaturated fats. These healthy fats may also help protect against dementia as you get older. Oysters are also a good seafood choice, because they’re rich in zinc. Zinc deficiency may adversely affect brain development, according to a review article published in Frontiers in Human Neuroscience in 2013.

Children and pregnant women are particularly sensitive to contaminants in fish, so choose those that are high in omega-3 fats but low in contaminants, such as wild salmon, sardines, Atlantic mackerel, mussels and rainbow trout for the recommended two servings per week of seafood to maximize benefits while minimizing risks.

Fruits and Vegetables

Antioxidant-rich fruits and vegetables, such as leafy greens and orange and red fruits and vegetables, may help protect your brain function and your memory as you age because of the beta-carotene and vitamin C they contain.

A diet rich in herbs, legumes, raw fruits and vegetables and cheese resulted in a higher IQ in children than a diet that included higher amounts of sweet and salty snacks, according to a study published in the European Journal of Epidemiology in July 2012.

Another study, published in the Journal of Child Psychology and Psychiatry in 2009, came to a similar conclusion, showing that children who ate higher amounts of fruits, vegetables and home-prepared foods had higher IQs.

Iron-Rich Foods

Iron-deficiency anemia may impair your attention span, IQ and ability to concentrate, so eat plenty of iron-rich foods. Increasing iron intake only appears to help IQ when children are deficient in iron, however, according to the Frontiers in Human Neuroscience article. Iron-rich foods include lean meats, oysters, beans, tofu, spinach, sardines and fortified breakfast cereals.

Other Protein-Rich Foods

Diets higher in protein and lower in fat may help improve your concentration because of the dopamine your body releases with protein consumption. Soy protein may be particularly helpful, since it also contains lecithin, which may improve memory and brain function. Lowfat dairy products, lean meats and poultry, eggs, nuts, seeds and legumes are all nutritious sources of protein.

Get Plenty of B Vitamins and Choline

Foods containing folate, vitamin B-12 and choline may also help keep your brain healthy, limiting your risk for dementia, depression and neurological disorders. They are also important for cognitive development, so if children don’t get enough of these vitamins they may have a lower IQ. Folate is available in fortified breakfast cereals, spinach, beef liver, rice, asparagus, black-eyed peas, Brussels sprouts and avocado, and most animal-based foods contain vitamin B-12. Good sources of choline include beef, eggs, scallops, salmon, chicken breast, cod, shrimp, Brussels sprouts and broccoli.
