Foods to Avoid for Anxiety

Foods to Avoid for Anxiety

Table of Contents

Anxiety and panic attacks affect millions of people worldwide, and while therapy, medication, and lifestyle changes are critical, one often overlooked factor is diet. Research increasingly points to how what we eat can either exacerbate or help alleviate anxiety symptoms. The gut-brain connection plays a crucial role, as the foods you consume influence neurotransmitter production, hormonal balance, and inflammation levels.


This blog dives deeper into the science behind dietary triggers, exploring foods that cause anxiety and panic attacks and those that can help reduce these symptoms. By understanding the foods to avoid and incorporating mood-boosting alternatives, you can build a diet that supports your mental health.

1. The Surprising Role of Sugar in Anxiety and Panic Attacks

Many people don’t realize that sugar can be one of the leading foods that cause anxiety. While it may provide a quick energy burst, sugar can cause a rapid spike in blood glucose levels, followed by a sharp drop, triggering cortisol (the stress hormone) release. This cycle leads to a feeling of hangriness—hungry and angry—which can contribute to anxiety after eating. Over time, frequent sugar consumption can worsen anxiety sensitivity by disrupting the hypothalamic-pituitary-adrenal (HPA) axis, which regulates stress response.


Hidden sugars to watch:

  • Flavored yogurts (up to 6 teaspoons per serving)
  • Granola bars marketed as “healthy”
  • Sauces like ketchup or barbecue sauce

Practical swaps:

  • Pair natural sugars (e.g., berries) with protein or fat to slow absorption. Try almond butter-stuffed dates as a snack.
  • Incorporate anti-inflammatory spices like cinnamon to satisfy sweet cravings without the glucose spikes.

By cutting back on sugary foods, you’ll reduce the foods that make anxiety worse and prevent blood sugar crashes that can contribute to mood swings.

2. Caffeine: A Hidden Anxiety Aggravator

While caffeine might give you a temporary energy boost, it can also have a significant impact on your anxiety symptoms. Caffeine works by blocking adenosine receptors, which prevents your brain from sensing fatigue, while simultaneously increasing adrenaline and norepinephrine—hormones that mimic the fight-or-flight response. For those prone to anxiety, even small amounts of caffeine can overstimulate the nervous system and trigger anxiety.
Beyond coffee:

  • Medications like Excedrin Migraine (65mg caffeine per tablet)
  • Matcha, despite its L-theanine content, still contains 70mg caffeine per cup
  • Decaf coffee (2-15mg per cup)

Tapering strategy:

  • Mix regular and decaf coffee over two weeks to avoid withdrawal headaches.
  • Replace afternoon caffeine with adaptogenic drinks like rhodiola or ashwagandha tea for sustained energy without overstimulation.

By eliminating caffeine, you’ll reduce foods that trigger anxiety, ensuring that your nervous system remains in balance throughout the day.

3. The Dangers of Processed Foods and Artificial Sweeteners

Processed foods and artificial sweeteners, commonly found in packaged snacks, can wreak havoc on your gut and brain. Artificial sweeteners and anxiety are linked in studies, showing that they can increase oxidative stress and affect the amygdala—the brain’s fear center—making anxiety worse.


The issue with processed foods:

  • Ultra-processed foods contain emulsifiers like polysorbate-80, which can increase intestinal permeability (“leaky gut”) and allow inflammatory compounds to cross into the bloodstream, potentially activating microglial cells linked to anxiety disorders.
  • Artificial sweeteners like aspartame increase oxidative stress, contributing to mood instability and heightened anxiety.

Label literacy tips:

  • Avoid anything with “hydrogenated oils” or “natural flavors” (a catch-all term for 100+ chemicals).
  • Opt for frozen vegetables over canned to minimize sodium benzoate exposure.

By replacing processed snacks with whole, nutrient-dense foods, you can reduce foods that contribute to anxiety and stabilize your mood.

4. Dairy Sensitivities and Anxiety: What You Need to Know

Dairy can be a surprising culprit for some people when it comes to anxiety. Does dairy cause anxiety? For those who are lactose intolerant or sensitive to casein (milk protein), dairy can cause inflammation, making panic attacks after eating more likely. During digestion, casein breaks down into casomorphins, opioid-like peptides that may impair cognitive function in sensitive individuals.


Non-dairy alternatives:

  • Calcium sources: Sardines with bones, bok choy, tahini
  • Probiotic-rich swaps: Coconut kefir, sauerkraut, kimchi
  • Baking substitutes: Aquafaba (chickpea brine) for whipped textures

Elimination protocol:

  • Remove dairy for 21 days, then reintroduce fermented options like Greek yogurt. Track sleep quality and morning anxiety levels to determine if dairy impacts your mental health.

Switching to non-dairy alternatives can help you avoid foods that make you anxious and support better gut health.

5. The Impact of Junk Food on Mental Health

Junk food—especially those high in trans fats—can have a detrimental impact on mental health. Trans fats integrate into neuronal cell membranes, reducing fluidity and impairing serotonin receptor function. Studies show that every 1% increase in trans fat consumption correlates with a 12% higher risk of anxiety symptoms.


Brain-damaging additives:

  • Monosodium glutamate (MSG) in chips: Overexcites neurons.
  • Butylated hydroxyanisole (BHA) in crackers: Linked to neuroinflammation.

Healthy snack alternatives:

  • Kale chips tossed in nutritional yeast
  • Air-popped popcorn with turmeric and black pepper

Replacing junk food with nutritious snacks can reduce foods that affect your mood negatively, stabilizing your mental health.

6. Foods That Help Reduce Anxiety and Promote Calm

Building an anxiety-resilient diet involves including foods that nourish both the body and mind. Here are some of the best foods for anxiety:
Magnesium-rich foods:

  • Pumpkin seeds (156mg per ¼ cup)
  • Spinach (78mg per ½ cup cooked)
  • Dark chocolate (64mg per ounce)

Omega-3 fatty acids:

  • Wild salmon (EPA/DHA reduces amygdala hyperactivity)
  • Walnuts (ALA converts to EPA in some individuals)

Fermented foods:

  • Kombucha (contains GABA-producing bacteria)
  • Miso soup (enhances BDNF for neural plasticity)

Sample anxiety-smart meal: Grilled salmon over quinoa with roasted Brussels sprouts and a side of kimchi. Dark chocolate-covered almonds for dessert.


These foods can help calm your nervous system and reduce foods that trigger anxiety while promoting a more balanced mood.

Conclusion: Managing Anxiety Through Diet

Diet plays a crucial role in how we feel, both physically and mentally. If you’re wondering, “Can food cause anxiety?” the answer is yes. But the good news is that small changes in your diet can make a big difference in how you manage anxiety. Start by swapping out one high-anxiety food each week and track how your body responds.

  • Week 1: Swap soda for sparkling water with crushed berries.
  • Week 2: Replace milk chocolate with 85% dark chocolate.
  • Week 3: Try cauliflower rice instead of fried side dishes.

By incorporating more foods for anxiety and reducing foods that make you anxious, you’ll create a foundation for a calmer, more resilient mind. Remember, dietary changes work best when combined with other anxiety-reducing practices like breathwork and mindfulness meditation.

10. Does eating cause anxiety?

Eating itself doesn’t typically cause anxiety, but the type of food consumed can influence how you feel afterward. Foods high in sugar or caffeine can spike anxiety symptoms, while a balanced diet can help keep you calm and prevent anxiety attacks. Eating smaller, balanced meals throughout the day is a good strategy for managing anxiety.
