Carbs Anxiety

Have you ever felt anxious or jittery after consuming a meal high in carbs? You’re not alone. Many people experience a connection between their carb intake and their anxiety levels, leading some to ask, “Why do I get anxiety when I eat?” In this blog, we’ll explore the relationship between carbs and anxiety, the science behind it, and what you can do to manage it. WebMD provides a wealth of resources on diet and anxiety management.

Carbs Anxiety: Understanding the Connection

Carbs are a staple in many people’s diets, providing the body with the necessary energy to function properly. However, it’s common for people to feel anxious or jittery after consuming a meal high in carbs. This phenomenon has been coined “carb anxiety.”

The connection between carbs and anxiety can be attributed to the way the body processes these nutrients. When we consume carbs, our body breaks them down into glucose, which provides energy to the brain and body. However, this process also triggers the release of insulin, a hormone that regulates blood sugar levels.

The Science of Carbs and Anxiety: How It Works in the Body

Insulin release can cause blood sugar levels to drop rapidly, leading to hypoglycemia. Hypoglycemia can cause shakiness, sweating, and even anxiety or panic attacks. The American Diabetes Association offers more information on hypoglycemia and its symptoms.

Additionally, consuming simple carbs, such as those found in sugar and processed foods, can lead to a spike in blood sugar levels followed by a rapid drop, causing similar anxiety symptoms.

Types of Carbs and Their Effect on Anxiety Levels

Carbohydrates are a type of macronutrient that the body uses for energy. They are found in many foods, including grains, fruits, vegetables, and sweets. However, not all carbs are created equal, and some may have a greater impact on anxiety levels than others.

Simple Carbs: Simple carbohydrates comprise one or two sugar molecules and are quickly absorbed by the body. These carbs can cause a rapid spike in blood sugar levels, followed by a quick crash. Simple carbs include sugar, honey, fruit juice, and white bread.

Complex Carbs: Complex carbohydrates comprise long chains of sugar molecules and take longer for the body to digest. These carbs provide a more sustained energy source and help regulate blood sugar levels. Examples of complex carbs include whole grains, legumes, fruits, and vegetables.

Refined Carbs: Refined carbohydrates are processed carbohydrates with bran and germ removed, leaving only the starchy endosperm. These carbs are often found in processed foods, such as white bread, pasta, and sugary snacks. Refined carbs have a high glycemic index, which means they can cause a rapid increase in blood sugar levels and may contribute to anxiety symptoms.

Unrefined Carbs: Unrefined carbohydrates are whole foods that are not processed or refined. These carbs are often high in fiber, which can help regulate blood sugar levels and promote feelings of fullness. Examples of unrefined carbs include whole grains, fruits, vegetables, and legumes.

Generally, a diet high in simple and refined carbohydrates and low in complex and unrefined carbohydrates may contribute to anxiety symptoms. On the other hand, a diet that is rich in complex and unrefined carbohydrates, such as a Mediterranean-style diet, may help reduce anxiety levels.

The Glycemic Index and Its Impact on Anxiety

The glycemic index measures how quickly a food raises blood sugar levels. Foods with a high glycemic index, such as white bread and sugar, cause a rapid rise in blood sugar levels, followed by a quick drop, leading to anxiety symptoms.

Foods with a low glycemic index, such as whole grains and vegetables, are processed more slowly in the body, leading to a steadier release of glucose and a more stable blood sugar level, reducing the risk of anxiety symptoms.

Managing Carbs and Anxiety: Tips and Strategies

If you experience carb-related anxiety, there are several strategies you can try to manage your symptoms. These include:

  • Choosing complex carbs over simple carbs
  • Eating small, frequent meals throughout the day
  • Balancing carbs with protein and healthy fats to slow down digestion and prevent blood sugar spikes
  • Incorporating stress-reducing activities, such as yoga or meditation, into your daily routine
  • Getting regular exercise to help regulate blood sugar levels and reduce anxiety

Foods that Cause Anxiety and Panic Attacks

As previously mentioned, consuming carbohydrates can temporarily relieve anxiety symptoms, but some foods can exacerbate anxiety and even trigger panic attacks. Some of these include foods to avoid anxiety:

  1. Caffeine: Found in coffee, tea, chocolate, and many sodas, caffeine is a stimulant that can increase heart rate, elevate blood pressure, and trigger anxiety symptoms in some people.
  2. Alcohol: Although alcohol can initially reduce feelings of anxiety, it can also lead to rebound anxiety once it wears off. In addition, excessive alcohol consumption can cause various physical and mental health problems.
  3. Sugar: Similar to carbohydrates, consuming large amounts of sugar can cause a spike in blood sugar levels followed by a crash, leading to feelings of fatigue, irritability, and anxiety.
  4. Processed and fried foods: These types of foods can be high in trans fats, which have been linked to an increased risk of depression and anxiety.
  5. Foods high in histamine: Certain foods such as aged cheeses, fermented foods, and processed meats can be high in histamine, which can cause symptoms such as anxiety, headaches, and dizziness in some people.

It is important to note that everyone is different, and what triggers anxiety or panic attacks in one person may not affect another person. Keeping a food diary and tracking how different foods affect your mood and anxiety levels can help identify triggers and make dietary changes accordingly.

Foods that Reduce Anxiety Fast: Antianxiety Diet, Carbohydrate diets, Ketogenic Diet

The antianxiety diet is a diet that focuses on consuming foods that have been found to reduce anxiety and promote calmness. Some of the foods recommended on this diet include dark chocolate, salmon, turmeric, chamomile tea, and spinach. These foods are rich in nutrients such as omega-3 fatty acids, magnesium, and antioxidants, which are thought to affect mood and anxiety positively.

Carbohydrate diets are another dietary approach that has been suggested to help reduce anxiety. Carbohydrates are known to stimulate the production of serotonin, a neurotransmitter that is linked to mood regulation. Complex carbohydrates, such as whole grains, fruits, and vegetables, are recommended over simple carbohydrates like candy, soda, and other sweets, which can lead to blood sugar spikes and crashes, leading to anxiety symptoms.

The ketogenic diet is a low-carbohydrate, high-fat diet that has been found to help manage anxiety symptoms. The theory behind this diet is that by reducing carbohydrate intake, the body enters a state of ketosis, which leads to increased production of ketones, which can help reduce anxiety. However, research on the effectiveness of the ketogenic diet in managing anxiety is limited, and this diet is not recommended for everyone.

Carb and Mental Health

In recent years, there has been growing awareness of the connection between diet and mental health. While most people understand that a balanced diet is important for physical health, many are unaware of how food can impact mental health. In particular, there has been increasing interest in the link between carbs and anxiety. While some believe that carbs can worsen anxiety symptoms, others suggest they may benefit mental health.

The Connection Between Carb Restriction and Anxiety

Can carbs cause anxiety? Low-carb diets have become increasingly popular recently, with many people following them for weight loss and other health benefits. However, some experts have raised concerns about the potential negative impact of carb restriction on mental health. Studies have shown that low-carb diets may increase the risk of mood disorders, including anxiety and depression. This is thought to be because carb restriction can decrease serotonin levels in the brain.

Low Carb Diet Cured My Anxiety?

Some studies have shown that a low-carb diet may positively impact anxiety symptoms. This is because low-carb diets can stabilize blood sugar levels and reduce inflammation, which can contribute to anxiety. Nonetheless, it is important to note that individual experiences may vary and that a low-carb diet should not replace professional mental health treatment. It is always advisable to consult with a healthcare professional before making significant dietary changes.

Finding a Balance

While the relationship between carbs and anxiety is complex, there are steps you can take to optimize your diet for better mental health. Focus on eating a balanced diet that includes a variety of whole, nutrient-dense foods, including complex carbs. This will help ensure you get the nutrients you need to support both physical and mental health. If you are considering a low-carb diet, talk to your doctor or a registered dietitian to determine if it is right for you.


While the link between carbs and anxiety is not fully understood, growing evidence suggests that carbs can play a role in regulating mood and reducing anxiety symptoms. By focusing on a balanced diet that includes complex carbs, you can help support both physical and mental health. If you are concerned about your diet and its impact on anxiety, talk to your doctor or a registered dietitian for guidance and support.
