The Childhood Foods That Increase IQ

The more of the foods they consumed, the higher their IQs.

A diet low in sugars, fats and processed foods consumed at a young age may increase your intelligence, research finds.

Children under 3-years-old fed diets that are packed full of nutrients and vitamins have higher IQs.

The more healthily they eat, the higher their IQ.

The study followed the wellbeing and health of 14,000 children born between 1991 and 1992 in the UK.

What they ate was tracked up to the age of 8, when they were given an intelligence test.

The results showed that children who ate a health-conscious diet including more salad, rice, pasta, fish and fruit had higher IQs at age 8.

Those consuming more junk food high in fats and sugars had lower IQs.

The study’s authors conclude that:

“…a poor diet associated with high fat, sugar and processed food content in early childhood may be associated with small reductions in IQ in later childhood, while a healthy diet, associated with high intakes of nutrient rich foods described at about the time of IQ assessment may be associated with small increases in IQ.”

There was little effect on IQ from what children ate between ages 4 and 7.

The authors say:

“This suggests that any cognitive/behavioural effects relating to eating habits in early childhood may well persist into later childhood, despite any subsequent changes (including improvements) to dietary intake.
It is possible that good nutrition during this period [under 3 years-old] may encourage optimal brain growth.”

The study was published in the Journal of Epidemiology and Community Health (Northstone et al., 2011).

Fun Fact Friday

  • Intelligent men tend to be more faithful.

  • If you eat pizza once a week it can decrease the risk of esophageal cancer.

  • Cheaters think everyone cheats. Liars think everyone lies.

  • People with anxiety perceive the world differently — their brain lumps both safe and unsafe things together and labels them all unsafe.

Can Eating Fish Make Kids Smarter?

Myth has it that fish is brain food – but it just might be more than myth, a new study suggests.

Kids who ate fish at least once a week had intelligence quotients, or IQs, that were nearly 5 points higher than the IQs for kids who ate less fish or none at all, the study found. Fish eaters also slept better.

Though the study was done among Chinese children, American kids are just as likely to benefit from fish, according to lead researcher Jianghong Liu, an associate professor of nursing at the University of Pennsylvania School of Nursing in Philadelphia.

“We need to modify the American diet for the betterment of our children,” she said.

“If parents want their children to be healthy and higher-performing, they should put fish on the table once a week,” Liu said. “That is not too much to ask.”

Although the study cannot prove that eating fish accounted for the higher IQs and better sleep, they do seem to be associated, she said.

According to the researchers, the benefit in IQ can be pinned to the better sleep afforded by omega-3 fatty acids found in many types of fish.

Good foods for brain health

To find out if fish was linked to benefits in children’s health, Liu and her colleagues studied the eating habits of more than 500 boys and girls in China, 9 to 11 years old. The children completed a questionnaire about how often they’d eaten fish in the past month, with options that ranged from never to at least once a week.

The kids also took the Chinese version of an IQ test that rates verbal and nonverbal skills, called the Wechsler Intelligence Scale for Children-Revised.

In addition, the children’s parents answered questions about their child’s sleep quality. The information collected included how long kids slept, how often they woke during the night and whether they were sleepy during the day.

Liu’s team also took into account other factors that could influence the findings, such as the parents’ education, occupation and marital status and the number of children in the home.

The team found that children who ate fish at least once a week scored 4.8 points higher on the IQ tests than those who seldom or never ate fish. Kids whose meals sometimes included fish scored slightly more than 3 points higher.

Moreover, eating more fish was linked with better sleep.

One U.S. nutritionist, however, says that advice to eat fish should be taken with a grain of salt.

“It’s not that eating fish is unhealthy per se, but there are issues that need to be considered before parents go overboard feeding fish to their kids to make them smarter and sleep better,” said Samantha Heller, a senior clinical nutritionist at New York University Medical Center in New York City. She was not involved with the study.

Fish is a good source of lean protein and is high in omega-3 essential fatty acids, she said. These acids are highly concentrated in the brain and play important roles in neurological function. They are essential for brain, eye and neurological development in fetuses. They are also necessary for eye, heart and brain health in adults and may reduce systemic inflammation, Heller said.

“The concern with eating fish is not only the overfishing of our seas, but the amount of mercury – a neurotoxin – found in fish,” she said.

The U.S. Food and Drug Administration recommends only one to two 2-ounce servings of low-mercury fish a week for children ages 4 to 7; 3 ounces for children 8 to 10; and 4 ounces for children 11 and older, Heller said.

Five commonly eaten fish that are low in mercury are shrimp, canned light tuna, salmon, pollock and catfish, according to the FDA.

“A healthy, balanced diet, plenty of exercise and limited computer and screen time can all help kids sleep better and do better in school,” Heller said.

The study was published online Dec. 21 in the journal Scientific Reports.

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).
