‘Feel-good’ food may be addictive, though direct evidence has not been found

‘Feel-good’ food may be addictive, though direct evidence has not been found | Longevity science | Scoop.it

High levels of sugar, fat and salt, and various flavors and food additives might actually hijack the pathways of the brain in ways that are similar to opiates and other drugs.

The evidence suggests that sugar in particular stimulates a greater release of chemicals in the brain — including dopamine, the “pleasure molecule” — than releases triggered by, say, fruit and vegetables. Over time, the brain’s circuitry might become rewired to produce less dopamine in response to high-calorie, flavor-enhanced foods.

Parkinson’s breakthrough could slow disease progression | KurzweilAI

Parkinson’s breakthrough could slow disease progression | KurzweilAI | Longevity science | Scoop.it

Northwestern University scientists have developed a new family of compounds that could slow the progression of Parkinson’s disease.

 

Parkinson’s, the second most common neurodegenerative disease, is caused by the death of dopamine neurons, resulting in tremors, rigidity and difficulty moving. Current treatments target the symptoms but do not slow the progression of the disease.

 

The compounds work by blocking calcium. The compounds target and shut a relatively rare membrane protein that allows calcium to flood into dopamine neurons.
