Understanding Sugar and Dopamine

By Courtney Morrissey MS, RDN, LD

It’s true that sugar triggers dopamine release, which can make us feel good temporarily. However, over time, excessive sugar intake can reduce dopamine receptor sensitivity, leading to a cycle where more sugar is needed to achieve the same pleasurable response.

Breaking a sugar addiction is a process that involves making gradual, sustainable changes. Small steps towards a healthier lifestyle can lead to lasting improvements in both physical and mental well-being.
Your emphasis on a balanced diet is crucial. Including a variety of nutrients—proteins, fiber, healthy fats, and complex/high fiber carbohydrates—helps maintain stable blood sugar levels, which in turn reduces cravings. For protein, consider lean meats, fish, eggs, beans, and nuts. High fiber carbs include whole grains, fruits, and vegetables.

Reading nutrition labels is a smart approach to limiting added sugar intake. Besides aiming for less than 8 grams of added sugar per serving, be aware of other terms for sugar in the ingredient list, like sugar, high fructose corn syrup, cane sugar, and syrup.

Consuming regular meals and avoiding meal skipping can help maintain stable blood sugar levels and prevent impulsive eating. Preparing meals ahead of time and incorporating healthy snacks can help manage hunger and reduce the temptation to reach for sugary foods.
Regular exercise boosts dopamine levels naturally and helps regulate mood. Aim for activities you enjoy, making it a sustainable part of your daily routine.

Quality sleep is vital for overall health and can help regulate cravings and mood. Establishing a consistent sleep schedule and creating a restful environment can improve sleep quality.
Including protein in your meals and snacks helps provide the amino acids needed for dopamine production. Foods rich in tyrosine and phenylalanine, such as chicken, turkey, fish, tofu, and legumes, are beneficial.

By adopting these practices, you can gradually reduce your dependence on sugar and support your overall health and well-being.
