Fruit During Pregnancy Boosts Baby’s IQ and Cognitive Development

fruit in pregnancy

Fruit isn’t typically linked with cognition and intelligence, but this may change. A baby’s cognitive development is directly linked not only to intelligence, but to avoiding neurological issues such as autism and intellectual disability (once called mental retardation.)

The reality is, fruit has some very important nutrients and phytochemicals. These functionally perform as brain foods during the developing fetus and infant years.

There are many different types of fruits. But they have something in common: Plants work hard to protect their fruit. They want to protect their fruits because they contain their own offspring.

Fruit, seeds and synchronicity

Fruit is an encasement of seeds. These seeds are the plant’s offspring. So they create these gorgeous fruits with complex layers of peels and various phytochemicals in order to protect their seeds from the damaging effects of the sun or any number of invaders. These include bacteria, fungus and so many others.

But the fruit that plants produce are not intended to protect the seeds from being picked and eaten by humans or animals. In fact, their colors even attract us to eat them. Why?

Because when humans and animals eat fruits, they will not digest the seeds. The seeds are wrapped in a hard shell that will either be spit out or be ejected through the feces. This means, of course, that humans and animals that eat fruit are actually working for the plants – to spread their seeds far and wide, along with the fertilizer to nourish their early growth.

This is just one of those beautiful synchronicities of nature. But it is also one of intelligence. Plants are very intelligent. They know what is happening to their seeds. They also know how to protect their seeds. Take a look at practically any tree or bush that produces fruit. Each tree produces a tough combination of peel and phytocompounds that protect their seeds from invasion.

These very same phytocompounds are also protective for those who ingest the fruits. Fruits provide numerous important nutrients for humans and other critters. These range from many vitamins and minerals to phenolic acids such as gallic acid and many others.

These functional compounds help nourish our bodies but also our brains. And as new research has confirmed, when a pregnant mother eats more fruit, this boosts her baby’s cognitive development.

The Living Cleanse

Mother’s eating fruit helps baby’s cognitive development

The research comes from University of Alberta’s Faculty of Medicine & Dentistry in Canada. The researchers utilized data from the Canadian Healthy Infant Longitudinal Development (CHILD) Study. This nationwide study of infants included more than 3,500 Canadian infants and their families.

The study, published in the journal EbioMedicine, followed over 800 children from Edmonton, Canada. In the final analysis, 688 children were tracked and followed through one year of age. Location along with other controls helped the scientists rule out other factors that affect a child’s cognitive development. This includes family income, parent’s education, gestational age and so on.

The study utilized a food frequency questionnaire developed by the Fred Hutchinson Cancer Research Center. This was modified for ethnic foods. The mothers completed the 175-item questionnaire at the beginning of the study. The pregnant mothers were asked for portion size and frequency of each food type eaten during their pregnancy.

Total fruit intake utilized servings of fruit. A serving of fruit was measured as either a three-quarters cup of 100% fruit juice, half a cup of fresh fruit, or a quarter cup of dried fruit.

The researchers measured cognitive development using the Bayley Scale of Infant Development (BSID-III). This is validated system of measuring cognitive development for infants between one and 42 months of age. The BSID-III scale has 91 items, and includes visual preference, attention, memory, exploration, manipulation, and concept formation. It also uses a 241-item behavior questionnaire that measures communication, behavior and other situations.

The researchers found the children of the fruit-eating mothers had a 2.38 point increase in cognitive development during the one-year period.

Translating this to a traditional IQ scale, the scientists found that children of pregnant mothers who ate an average of six or seven servings of fruit or fruit juice per day had between six and seven IQ points higher at the end of their first year.

Senior researcher of the study and professor of pediatrics, Dr. Piush Mandhane, found the correlation. “It’s quite a substantial difference—that’s half of a standard deviation. We know that the longer a child is in the womb, the further they develop—and having one more serving of fruit per day in a mother’s diet provides her baby with the same benefit as being born a whole week later,” said Dr. Mandhane.

The average IQ is 100, and the standard deviation is 15. This means that two-thirds of the population will have an IQ of between 85 and 115. So six or seven points greater IQ on average is a significant difference. Especially just for eating more (delicious) fruit.

The effect of eating fruit during pregnancy was translated to a 30 percent increase in cognitive development when the researchers applied the results to a laboratory model. They utilized using fruit flies, which have similar brain development to humans.

Blueberry boosts memory for 8-10 year-olds

A study from the UK’s University of Reading tested 14 children between 8 and 10 years of age. The researchers gave half the children a drink spiked with blueberry and flavonoids. (Fruit contains lots of flavonoids). The other half received a placebo drink with similar flavoring.

Two hours after drinking the drink, the researchers gave the children a battery of cognition tests. These included tests for memory, attention, moods, and responsiveness.

The children drinking the blueberry drink had significantly increased scores in the delayed recall of a list of previously learned words.

Caution on fruit juice

We should note that the study included fruit juices. Other research has illustrated – as we’ve reported in this publication – that fruit juice does not have the same health benefit as consuming raw fruits.

One of the reasons for this is that fruit juices are typically pasteurized. Many of the nutrients and phytocompounds in fruits are heat sensitive. Thus, they will disappear or be substantially decreased in fruit juice.

And because fruit juice producers typically filter out most of the pulp and fibers from the fruit, those phytochemicals found in the inner peels and fibers of the fruit are typically absent or minimized in fruit juice.

Because of this lack of fiber, fruit juices can spike blood sugar levels significantly. This can have a negative effect upon a baby’s development.

My suggestion is to therefore eat raw fruit. If a beverage is desired, putting the raw fruit into a blender – to make a fruit smoothie. Fruit smoothies can also be spiked with green foods and flaxseeds, and even probiotics yogurt. All of these will assist in boosting cognitive development of mother and baby.

I had just spent the last two hours explaining how diet, sleep and other lifestyle choices create health problems and how changes in these, along with certain herbal medicines and other natural strategies can radically yet safely turn ones health around. As I drove home that night, I realized I needed to get this knowledge out to more people. So I began writing about health with a mission to reach those who desperately need this information.
