If drugs and supplements aren’t your thing, or you have been advised by a medical professional that they might not be suitable for you, there is still hope; small modifications to diet have been shown to induce mild benefits for symptoms of ADHD.
A landmark study was published in 2011 in the Lancet Journal, setting the ADHD field on fire by suggesting that diet, without drugs, could help alleviate ADHD symptoms.
Certain foods have long been known to increase dopamine, especially sugar. It has also been shown that children (and adults) with ADHD tend to pursue sugary foods to a larger degree than those without ADHD, likely as a subconscious craving to improve their impulsivity and lack of focus.
Elimination diets have also been tested, where certain foods are eliminated to see their effects, if any, on health and function.
One such diet is the oligoantigenic diet, a dietary approach that involves temporarily removing certain foods from the diet that are considered potential allergens or triggers for adverse reactions.
This study showed a significant reduction in ADHD symptoms immediately after a four-week oligoantigenic treatment, where the “responder rate”, defined as a 40% decrease in ADHD Rating Scale (ARS) total value, was about 64% after four weeks of the diet. Other studies have reported similar response rates, ranging from 60% to 73%.
The study found that eliminating foods that children have mild allergies to can dramatically improve their ADHD symptoms. It seemed as if eliminating simple sugars was the most dramatic factor.
There are a notable number of critics of this sort of diet, however. Opponents suggest that the structure of such experiments has so far been poor and that when children are not exposed to certain foods, such as nuts and seeds, they can later develop allergies to them.
While the verdict is still out on oligoantigenic diets, abundant evidence has shown that avoiding high-sugar diets (those containing simple sugar foods) is beneficial for many health aspects, and potentially for ADHD.
Like all natural supplements, it is important to note that diet does not mediate ADHD – it only indirectly modulates it. You will never solve ADHD with diet alone, but it might help offset and soften some of its symptoms.
