Why Your Little Ones May Be Driving You Mad

Food sensitivities and children's behavior have been linked. Believe it or not, what we feed our little ones may be the root cause of many disorders. Diet affects both our neurotransmitters and brain. Food is the building block that becomes our foundation. Food sensitivities may be the culprit to why your little ones are experiencing behavioral problems like attention deficit hyperactivity disorder (ADHD), increased hyperactivity, impulsivity, lack of concentration or cooperation, outbursts, stomachaches, rashes, and headaches. Eliminating certain foods from the diet may significantly help some children.According to recent data from the Centers for Disease Control and Prevention (CDC), 6.4 million American kids have been labeled with the medical diagnosis. Of which, 4.3 million kids received powerful mind-altering stimulant medications. Some things you can try at home before placing your child on a heavy prescription drug includes testing for and eliminating food sensitivities. The following have been linked to behavioral problems and eliminating these from the diet is a great place to start: gluten, processed sugar, artificial sweeteners like aspartame, dairy, eggs, soy, preservatives, pesticides, MSG, genetically modified food, and artificial food dyes such as FD&C blue (1, 2), yellow (5, 6), green (3), red (3, 40), citrus red 2, and orange B.If your child is consuming something they are sensitive to resulting in inflammation in the brain, this can lead to meltdowns, irritability, anxiety, depression, and brain fog. Unaddressed food sensitivities can also lead to leaky gut, which will further impact behavior and may lead to malabsorption of vital nutrients needed for growth and development. A noticeable negative behavioral reaction from food can last anywhere from 24 hours to three days.

What You Can Do

In order for children to stay focused and energized, they should start their days with balanced blood sugar. Protein helps to do this and stabilize healthy growth. However, cereals filled with processed sugars, artificial colors and preservatives promote energy peaks and crashes that can lead to temper tantrums and loss of focus. Add an omega-3 fatty acid DHA supplement, check vitamin D levels, add a wide spectrum probiotic, and increase dietary fat (olive oil, coconut oil, flax oil, nuts, seeds, avocado). Buy organic, become familiar with the Dirty Dozen and read food labels— if you don’t recognize an ingredient, don’t buy the food product and give it to your child to consume. By taking time to prepare healthy food you are showing your children the importance of healthy eating and living.Read more here about food sensitivities and testing.

Bartonella is a bacterial infection that often appears alongside Lyme. In the US there is no current evidence that ticks transmit it, and the question is still under investigation. The proven routes are cat scratches and bites, cat-flea feces, and body lice. It is hard to detect, which is why a thorough Lyme workup checks for it properly.

Babesia is a malaria-like parasite carried by the same tick that carries Lyme. Because it is a parasite and not a bacterium, the antibiotics typically used for Lyme have no effect on it. It is seldom tested for, so people can finish Lyme treatment, still feel sick, and not understand why.

The CDC classifies Washington DC, Maryland, and Virginia as high-incidence areas for Lyme. Standard two-tier blood testing catches only 22 to 36 percent of early infections, so a negative result does not rule Lyme out when symptoms are present. Free state and county programs identify a tick's species but do not test it for disease, and broader co-infection testing is not routinely ordered.
