Can the food you eat affect your attention, focus, or restlessness? There is no clear scientific evidence that food or nutritional problems directly cause attention deficit hyperactivity disorder, or ADHD. However, some studies show that certain foods may have some effect on symptoms in a small number of people.
So, are there any foods that you should avoid if you have this condition? Or if your child has this condition, should you change their diet? Let's talk about this in a simple way that everyone can understand. But before trying any of these things, you should definitely talk to your doctor , because some foods can affect the medications you take.
What is an 'ADHD Diet' that helps with ADHD?
When it comes to a diet that helps with ADHD, it's not a one-size-fits-all rule. It varies from person to person, depending on their needs. Simply put, it's a set of eating habits that can help your brain function and help reduce symptoms like restlessness and inattention.
There are three main ways to approach this:
- Maintain a balanced diet: Here we focus on the fact that some foods can improve symptoms and some foods can worsen them. Also, you may be missing out on some nutrients that can help reduce symptoms.
- Taking supplements: In this method, you add nutritional supplements, such as vitamins and minerals, to your diet. The idea is that if you don't get enough of these from your diet, the deficiency can worsen your symptoms.
- Elimination Diet: This involves completely eliminating certain foods or their ingredients that you think are affecting your behavior or symptoms.
What is good for someone with ADHD to eat?
There hasn't been much research on specific diets for ADHD. The data is limited and the results are mixed. However, many health experts believe that the foods we eat can help alleviate symptoms .
According to experts, anything that is good for the brain is likely to be good for ADHD.
So let's see what's good to add to meals.
| Food type | Description and importance |
|---|---|
| Protein-rich foods | Beans, peas, cheese, eggs, meat, and nuts like cashews and peanuts are good sources of protein. Including these in your breakfast and afternoon snacks can help you focus better . They can also help ADHD medications last longer. |
| Complex Carbohydrates | These are the "good carbohydrates." Vegetables and some fruits like oranges, pears, apples, and kiwis belong to this group. They are digested slowly in the body and provide energy for hours . When added to your evening or dinner meal, they can also help you get a good night's sleep. |
| Omega-3 fatty acids | These are found in abundance in deep-sea fish like salmon and tuna. Walnuts, Brazil nuts, olive oil, and canola oil also contain omega-3s. These are very important for brain health . If necessary, you can also take an omega-3 supplement on the advice of your doctor. |
What should someone with ADHD not eat?
Some foods do not provide the nutrients you need for a healthy life. If you have ADHD, it is best to stay away from the following.
| Unhealthy food type | Examples and impact |
|---|---|
| Sugary foods | Sugar only adds calories, but it doesn't provide essential nutrients. It also causes diseases like diabetes and obesity. Reduce your intake of soft drinks, sweetened beverages, toffee, chocolate, cakes, biscuits, and packaged foods as much as possible. |
| Simple Carbohydrates | These are like "bad carbohydrates." They are quickly absorbed by the body, causing a sudden spike in blood sugar levels. Then they drop quickly, leaving you feeling tired and irritable. Examples include honey, sugar, bread, white rice, and potatoes without their skins. |
| Unhealthy Fats | Reducing the consumption of fried and baked foods, cream, cheese, full-fat milk, and high-fat meats (pork, beef) that are high in saturated fats like butter, ghee, coconut oil, and palm oil is very good for heart health. |
| Caffeine | If you're taking stimulant medications for ADHD, it's not a good idea to add another stimulant, caffeine. Coffee, tea, energy drinks, some soft drinks, and chocolate all contain caffeine. If these make you feel jittery or have trouble sleeping, it's wise to limit them. |
Things to add to the diet of a child with ADHD
Here are some foods that will help children develop healthy brains as they grow.
Eggs
The protein and nutrients in eggs help children focus . You can boil an egg for breakfast, or make an egg sandwich.
Greek yogurt
Fat is essential for brain health. Greek yogurt, which has more protein than regular yogurt, helps maintain good communication between brain cells.
Green vegetables
Leafy greens like spinach, kale, and collard greens are full of folate and vitamins. These help with brain cell growth. Since some kids don't like to eat greens, instead of a salad, you can make a smoothie with greens, or add them to an omelet or lasagna.
Fish
Fish is a good source of vitamin D and omega-3 fatty acids, which protect against brain aging and memory loss. Fish like tuna and salmon are especially good.
Oatmeal
Oats, which are high in protein and fiber, help keep blood vessels in the heart and brain clean. One study found that children who ate oats before school performed better on memory tasks than those who ate sugary cereal.
Are nutritional supplements good for ADHD?
Some experts say that people with ADHD should take a daily vitamin and mineral supplement. However, others say that if you eat a balanced diet, you don't need to take these supplements. They haven't been scientifically proven to help everyone with ADHD.
Consider this: Some studies have found a possible link between iron, zinc, omega-3, vitamin D, and magnesium deficiencies and ADHD. But these have not yet been widely proven.
So, if you or your child are considering taking a nutritional supplement, be sure to talk to your doctor first. Don't start anything without your doctor's advice. Remember, taking too many vitamins can be toxic to the body.
What is the truth about eliminating certain foods (Elimination Diet)?
In this method, you choose a food that you think is causing your symptoms and stop eating it completely. Then you see if your symptoms improve. Research on this is still ongoing, and the results are not clear. Therefore, most scientists do not recommend it for ADHD management.
However, there are a few things that some people are concerned about:
- Food additives: Artificial colors (especially red and yellow), sweeteners (such as aspartame, MSG), and preservatives are thought to increase hyperactivity in some children. Even the American Academy of Pediatrics now agrees that avoiding these is a reasonable option for children with ADHD.
- Sugar: Some children become hyperactive after eating foods high in sugar, but there is no evidence that this causes ADHD.
- Caffeine: As mentioned earlier, avoiding or limiting caffeine is best for most people.
If you try any of these things, do so only under the guidance of your doctor, as suddenly stopping certain foods can deprive your baby of the nutrients it needs.
Take-Home Message
- Although it has not been proven that diet directly causes ADHD, a balanced, nutritious diet can go a long way toward promoting brain health and managing symptoms.
- Before making any major changes to your or your child's diet, or before starting nutritional supplements such as vitamins, be sure to talk to your doctor.
- Try to include a diet rich in protein, complex carbohydrates (good carbohydrates), and omega-3s.
- Reducing sugary foods and drinks, simple carbohydrates, and artificial additives (colorings, flavors) as much as possible is good for everyone's health.
- Everyone is different. What works for one person may not work for another. So be patient, and with medical advice, find what works best for you or your child.
