According to the Merck Manual, a significant decrease in potassium levels can cause muscle weakness, cramping, and twitching. This confirms that yes, tricep twitching is related to potassium deficiency, also known as hypokalemia, though it's not the only possible cause.

The brain is one of the fattiest organs in the human body, composed of more than 55% fat. Far from being a dietary villain, fat is a critical component for nervous system function, serving as a primary structural and functional building block for neurons. Research increasingly shows that dietary fats and the body's lipid metabolism are inextricably linked to neuronal health, function, and resilience against disease.

According to researchers at Stanford Medicine, the ketogenic diet may help stabilize the brain by providing an alternative fuel source for those with energy dysfunction. This metabolic shift, known as ketosis, significantly alters brain chemistry and energy usage, raising important questions about what the keto diet does to your brain.

Recent research, including a 2025 study in *Biomedicines*, showed that fecal nervonic acid was significantly elevated in patients with inflammatory bowel disease, demonstrating a link between this fatty acid and inflammatory conditions. So, what does it mean when your nervonic acid is high, and what are the potential underlying causes?

While most forms of human prion disease occur spontaneously or are hereditary, one specific type, variant Creutzfeldt-Jakob disease (vCJD), has been linked to eating meat contaminated with Bovine Spongiform Encephalopathy (BSE). This connection first gained widespread attention during the 'mad cow disease' outbreak in the UK in the 1990s, raising serious food safety concerns. However, thanks to rigorous international regulations, the risk of contracting a prion disease from meat is now extremely low.

Studies have shown that over half of the adult population can be vitamin D deficient, a condition significantly associated with fatigue and reduced muscle strength, including weak grip strength. This reduction in manual strength often points to underlying nutritional issues that impact both muscle and nerve function.

According to reports, clinical copper deficiency is now more frequently recognized, presenting with a wide range of symptoms that can be easily misdiagnosed, highlighting the importance of understanding what diseases are associated with low copper. This essential trace mineral plays a critical role in numerous bodily functions, and its deficiency can lead to severe and systemic health problems.

According to research by food scientists, people offered a variety of foods can consume up to 60% more calories, illustrating a key principle behind the phenomenon of craving sweets even after a large meal. This complex interplay of biology and psychology explains why there's always room for dessert.

According to studies, high-dose intramuscular thiamine has been shown to rapidly and remarkably improve tremors in some patients with Essential Tremor. This vitamin, also known as B1, is essential for a properly functioning nervous system and plays a vital role in addressing various conditions that can cause shakes.

According to research on individuals with severe eating disorders, prolonged malnutrition can lead to brain atrophy, or shrinkage. This startling fact prompts the question: can being underweight affect your brain? The answer is a resounding yes, and the effects range from cognitive impairment to significant mood changes.
