NUT ITION BYTES By Geoff Brokx and Aryn Doll Increased Fruit and Vegetable Intake Reduces ADHD Symptoms in Children Recent research suggests that eating more fruits and vegetables may improve attention

consistent with previous studies that show lower fruit and vegetable intake is associated with a higher prevalence of ADHD diagnosis. Fruits and vegetables are well known to be nutrient dense in a wide variety of vitamins, minerals, and phytonutrients, unique plant compounds known for their health benefits. The micronutrients found in fruits and vegetables play important roles in neurotransmitter synthesis, necessary for healthy brain function. While the MADDY study did not analyze the di erences between organic and conventional fruits and vegetables, other studies have found a significant association between pesticide exposure and severity of ADHD symptoms. Based on the current research, incorporating more organic fruits and vegetables into your children’s diet is a smart move toward better brain health.

in children with attention deficit hyperactivity disorder (ADHD). This research comes at a time when ADHD—a neurodevelopmental disorder characterized by a pattern of inattention and/or hyperactivity—a ects one in 10 children in the United States. While ADHD is related to a variety of factors, researchers are looking at modifiable environmental factors, such as diet, for clues on how to help.

The MADDY Study, completed in May 2022, analyzed the diets of 134 children between six and 12 years old and compared various aspects of their diet with symptoms of ADHD. The study found children who ate less fruits and vegetables were more likely to have severe symptoms of inattention. The findings of this study are

LowVitamin K Status Associatedwith Cognitive Decline

Previous research has shown that low vitamin K status is associated with aging-related diseases, including osteoporosis and osteoarthritis, and now a brand-new study adds to these findings, demonstrating a potential connection between vitamin K insu ciency and cognitive impairment in older individuals. In the study, 800 older adults with an average age of 75 and living in Tokyo, were given a comprehensive geriatric health examination. The evaluation consisted of a Mini Mental State Examination (MMSE) to assess cognitive function and a blood test to measure levels of undercarboxylated osteocalcin (ucOC), with higher levels of this protein indicating greater vitamin K insu ciency. Researchers then evaluated the relationship between cognitive function and vitamin K status, finding that as levels of ucOC increased or vitamin K insu ciency worsened, so too did the likelihood of cognitive impairment. More specifically, individuals with the highest levels of ucOC had an increased prevalence of worse scores on the MMSE, particularly in the areas of orientation, calculation, and language.

Vitamin K is an often forgotten about nutrient, but studies like the one just described are an important reminder that getting adequate amounts is vitally important for maintaining our health throughout our years, including our cognition and mental faculties. Technically not a single vitamin, but a group of fat-soluble vitamins that includes two main forms (K1 or phylloquinone and K2 or menaquinone), adequate vitamin K is also essential for proper blood clotting, calciummetabolism, and cardiovascular, immune, bone, and reproductive health.
