Occurring naturally in the environment, heavy metals can be either beneficial or detrimental to the proper functioning of our bodies. While heavy metals such as magnesium, iron, and zinc contribute to our wellbeing in small amounts, the presence of arsenic, cadmium, lead, and mercury in our blood, even in trace amounts, can wreak havoc on the brain. This is because these heavy metals are neurotoxins.
Infants and toddlers are extremely vulnerable when it comes to exposure to heavy metals, as they have a higher uptake of nutrients by the gastrointestinal tract and underdeveloped detoxification systems.
Since arsenic, cadmium, lead, and mercury directly target the brain and nervous system, exposure to these heavy metals can eventually result in autism spectrum disorders such as Kanner’s syndrome, childhood disintegrative disorder, Asperger’s syndrome, or pervasive developmental disorder.
A congressional report made public in the winter of 2021 revealed that four major baby food manufacturers had allowed products with a tremendous concentration of heavy metals to go on the market. To understand how serious the problem is, let the following eye-opening findings sink in:
- Beech-Nut, one of the oldest baby food companies in the country, used ingredients containing over 900 ppb arsenic when the maximum limit is 10 ppb
- Hain Celestial Group, a company that sells baby food under the brand name Earth’s Best Organic, sold products with up to 260 ppb cadmium when the safe limit is 5 ppb
- Beech-Nut, whose products can be found in stores under the same name, used ingredients containing over 886 ppb lead when the maximum limit is 5 ppb
- Nurture, which sells baby food under the brand name HappyBABY, allowed products with 10 ppb mercury to go on the shelves when the safe limit is 2 ppb
Even though the Subcommittee on Economic and Consumer Policy, which led the investigation, had initially asked seven baby food manufacturers to partake in it, Campbell, Sprout Organic Foods, and Walmart refused.
The investigators were concerned about their lack of cooperation, as it could indicate that these baby food companies had manufactured products that contained even higher concentrations of heavy metals than those of their competitors.
The Effects of Ingesting Toxic Baby Food on Children’s Neurodevelopment
Most baby food on the market contains heavy metals because manufacturers fail to source their raw ingredients from organic farmers, even when they claim to do so.
Crops such as rice, carrots, sweet potatoes, wheat, barley, and quinoa absorb heavy metals from the soil they grow in and from the harmful pesticides that are regularly applied to them.
Organic agriculture entails practices that reduce the amount of heavy metals crops take in, such as alternating irrigation, growing rice in soil with a low arsenic content, and using food strains that are less prone to absorbing these neurotoxins. Unfortunately, organic farming is currently a fringe movement, as only 1% of the entire farmland in the United States is used for organic agriculture.
Because arsenic, cadmium, lead, and mercury are neurotoxins, they accumulate in the cerebral matter of children who are fed mostly toxic baby food. These heavy metals can easily cross the blood-brain barrier. The higher the blood concentration of heavy metals a child has, the greater their chances of developing a form of autism become. At the moment, 1 in 44 children born in or after 2010 in the country is on the spectrum.
Lead is perhaps the most dangerous heavy metal to the neurodevelopment of infants and toddlers, and, disturbingly, over 500,000 children between 1 and 5 in the United States have a blood lead concentration above the safe limit. Even in trace amounts, lead can impact brain development and function. High concentrations of lead in the body may cause infrastructural and metabolic abnormalities in the nervous system.
Once heavy metals settle in the brain tissue, they create free radicals – unstable atoms that can damage cells, causing serious health problems and premature aging. In turn, free radicals generate oxidative stress, which refers to the disruption in the natural balance between the production of free radicals and antioxidant defenses.
Oxidative stress can take a heavy toll on proteins, DNA, and cells. Studies found that children on the spectrum share a chronic flaw in the body’s natural defenses against free radicals.
Finally, it is important to explain how mercury affects the neurodevelopment of infants and toddlers. If a high mercury level exists in the cerebellar areas of the brain, neurotrophin-3, a marker of oxidative stress, will be found in the child’s body. Overall, children with autism spectrum disorders were found to have significantly higher concentrations of heavy metals in their blood and hair than their neurotypical counterparts.
5 Practical Ways You Can Avoid Feeding Your Baby Toxic Food
Luckily, if you are a new parent, there are many things you can do to minimize the amount of heavy metals your baby ingests. The following are five easy ways to avoid feeding your infant or toddler food with dangerous levels of heavy metals.
1. Breastfeed Your Newborn for as Long as Possible
While up to 80% of American mothers breastfeed their babies, fewer than one-third continue to do so for the recommended period of one year. So, if possible, breastfeed your child for as long as you can, as not only will this delay their need for commercial baby food, but it will also benefit their health.
Children who have been breastfed for at least one year have a lower risk of asthma, diabetes, sudden infant death syndrome, obesity, lung infections, stomach bugs, and ear infections.
2. Replace Store Baby Food with Raw, Natural Foods
This advice comes from the 2019 study conducted by the non-profit organization Healthy Babies Bright Futures, which found that a whopping 95% of the baby food on the market contains at least one heavy metal. Still, their researchers also offered valuable advice in the study to help parents avoid heavy metals in their children’s diet as much as feasibly possible, namely:
- replacing teething biscuits with a cold banana to reduce the heavy metal content by 91%
- replacing fruit juice with tap water to lower the heavy metal content by 68%
- replacing rice puff snacks with rice-free snacks to reduce the heavy metal content by 93%
- replacing sweet potatoes with other fresh produce to lower the heavy metal content by 73%
3. Give Your Child Rice Just Occasionally
Rice is a major source of arsenic, as rice crops often absorb up to 20 times more of this heavy metal than other crops. Therefore, it is preferable to feed your baby rice sparingly, and when you do it, you should rinse the grains in water multiple times and cook the rice in plenty of water. The water should be drained off when the meal is ready.
4. Choose the Fish You Feed Your Toddler Carefully
While rice is notorious for containing a lot of arsenic, certain fish is known to contain high concentrations of mercury.
For this reason, you should carefully do your research before deciding which type of fish you will give your toddler. Some of the fish you should avoid are swordfish, marlin, northern pike, fresh tuna, king mackerel, and tilefish, whereas the relatively clean, nutritious fish includes salmon, flounder, mullet, plaice, catfish, haddock, and pollock.
5. Make Your Own Baby Food
In this day and age, you can find millions of baby food recipes at the click of a button. Some of the meals you can prepare for your child do not even require cooking.
The most common and healthy options for infants are fruit and vegetable purées, such as banana, pea, avocado, sweet potato, and carrot purées. As for toddlers, when it comes to recipes, the sky is the limit – blueberry avocado mini muffins, banana pancakes, salmon curry, and the list goes on and on.
