10 foods that make you more aggressive

While diet plays a significant role in our overall health and well-being, it can also impact our mood and behaviour. Recent research suggests that certain foods might contribute to increased aggression or irritability. This article explores ten such foods and the scientific reasons behind their potential effects on aggression. This is especially in the light of the recent London riots!

1. Sugary Foods

Reason: Blood Sugar Spikes and Crashes

• Science: Consuming high-sugar foods can lead to rapid spikes and crashes in blood sugar levels. This rollercoaster effect can affect mood stability, leading to irritability and aggression.
• Study: Research published in the journal Frontiers in Endocrinology indicates that fluctuations in glucose levels can alter brain function, affecting mood and emotional responses .

2. Refined Carbohydrates

Reason: Impact on Serotonin Levels

• Science: Refined carbohydrates, such as white bread and pasta, can lead to similar blood sugar fluctuations as sugary foods. They may also impact serotonin levels, a neurotransmitter that influences mood and behavior.
• Study: A study in the American Journal of Clinical Nutrition found a correlation between the consumption of refined carbohydrates and increased depression and mood swings, which can manifest as aggression .

3. Trans Fats

Reason: Inflammatory Effects on the Brain

• Science: Trans fats, commonly found in processed and fried foods, can lead to inflammation in the brain, which may affect mood regulation.
• Study: A study published in PLOS ONE showed that individuals with high trans fat intake had more aggressive behaviors and were more likely to experience mood disorders .

4. Caffeine

Reason: Increased Stress Hormones

• Science: Caffeine stimulates the release of adrenaline, a hormone associated with the body's "fight or flight" response, which can increase feelings of anxiety and aggression.
• Study: Research in the journal Psychopharmacology indicates that caffeine consumption can increase irritability and aggression, especially in people sensitive to its effects .

5. Alcohol

Reason: Lowered Inhibitions

• Science: Alcohol can reduce self-control and increase impulsive behavior, leading to aggressive outbursts.
• Study: A study in Addiction found a strong link between alcohol consumption and aggressive behavior, particularly in social settings .

6. Artificial Additives

Reason: Neurotransmitter Disruption

• Science: Certain artificial colors and preservatives can interfere with neurotransmitter function, affecting mood and behavior.
• Study: Research in The Lancet highlights the impact of artificial food additives on behaviour, including increased hyperactivity and aggression in children .

7. Processed Meats

Reason: High Levels of Sodium and Preservatives

• Science: Processed meats often contain high levels of sodium and preservatives like nitrates, which can affect neurological health and behaviour.
• Study: A study published in the journal Neuropsychobiology linked high sodium intake with increased aggression and mood disorders .

8. Dairy Products

Reason: Lactose Intolerance and Inflammation

• Science: Some individuals are sensitive to dairy, leading to inflammation and discomfort, which can exacerbate irritability and aggression.
• Study: Research in Nutrition Journal suggests that inflammation from dietary sources, like dairy, can affect mood and lead to behavioural changes .

9. Red Meat

Reason: High Levels of Saturated Fat

• Science: Diets high in saturated fats, commonly found in red meat, can lead to inflammation and alter brain chemistry, affecting mood regulation.
• Study: A study in The Journal of Nutrition found that high saturated fat intake is linked to increased aggression and mood swings .

10. Spicy Foods

Reason: Increased Stress Response

• Science: Spicy foods can trigger the release of stress hormones, potentially leading to increased irritability and aggression.
• Study: Research published in Appetite indicates that spicy foods can affect emotional responses, including increasing feelings of anger and frustration in some individuals .

While the foods mentioned above can contribute to increased aggression, it is essential to note that individual responses can vary. Factors such as genetics, overall diet, and lifestyle choices play significant roles in how these foods affect mood and behaviour. For those looking to manage aggression or mood swings, maintaining a balanced diet rich in whole foods and low in processed ingredients can be beneficial. Consulting with healthcare professionals or nutritionists can also provide personalised guidance to support mental and emotional well-being.
