1. 6 Similarities Between Sugar, Junk Food and Abusive DrugsSugar and highly processed junk foods are addictive, just like drugs.Not only are the behavioural symptoms the same, but the biology also happens to agree.Here are 6 disturbing similarities between sugar, junk food and abusive drugs.
2. 1. Junk Foods Flood The Brain With DopamineWhen we eat, a brain hormone called dopamine is released in an area of the brain called the reward system. We interpret this dopamine signal as "pleasure" and this is actually a good thing... without dopamine, life would be miserable.But the problem is that some modern things (like drugs) can flood our brains with dopamine, way more than we were ever exposed to throughout evolution. Sugar and highly processed junk foods can have the same effect – they flood the brain with much more dopamine than we would get by eating real food, like an apple or an egg.This is why highly processed, sugar-laden foods can make (some) people lose control over their consumption. They hijack the same brain pathways as drugs of abuse.
3. 2. Junk Foods Can Lead to Powerful CravingsCravings are a powerful feeling. People often confuse them with hunger... but the two are not the same thing. Some people get cravings despite having just finished a fulfilling, nutritious meal.This is because cravings are not about satisfying your body's need for energy, instead it is your brain calling for "reward."Cravings for junk foods are actually very similar to cravings for drugs, cigarettes and other addictive substances. The obsessive nature and thought processes are identical.
4. 3. Junk Foods Light up the Same Brain Areas as Drugs of AbuseResearchers often use devices called functional MRI scanners to sense changes in blood flow in specific areas in the brain.Because the blood flow is directly tied to the activation of neurons, they can use these devices to measure which areas in the brain are being activated.Using such devices, studies have shown that both food and drug cues activate the same brain regions, and that the same areas are activated when people crave either junk food or drugs.
5. 4. A Tolerance to The "Rewarding" Effects Builds upWhen the brain gets flooded with dopamine, the brain starts reducing its number of dopamine receptors in order to keep things balanced. This is a well known feature of drugs of abuse. People need progressively larger and larger doses because the brain reduces its number of receptors.This implies that people who are addicted to junk food don't necessarily get any more pleasure from eating... because their brain cuts back on dopamine receptors in response to the repeated overstimulation.Tolerance is one of the hallmarks of addiction. It is common to all drugs of abuse... and applies to sugar and junk food as well.
6. 5. Many People Binge on Junk FoodsWhen addicts become tolerant to the effects of a drug, they start increasing the dosage. Instead of 1 pill, they take 2... or 10.Because there are now fewer receptors in the brain, a larger dose is needed to reach the same effect. This is the reason why some people binge on junk food.Binge eating is a well known feature of food addiction, as well as other eating disorders that share common symptoms with drug abuse.
7. 6. Abstaining Can Lead to Withdrawal SymptomsWithdrawal symptoms are another key feature of addiction. This is when addicted individuals experience adverse symptoms when they stop ingesting the substance they are addicted to.A prominent example is caffeine withdrawal. A lot of people who are addicted to caffeine get headaches, feel tired and become irritable if they abstain from coffee for long periods of time. There is evidence that this applies to junk food as well.
