Minerals

Brown sugar provides 83 times more calcium, 67 times more potassium, 16 times more manganese, 114 times more iron, seven times more copper, three times more zinc, and two times more selenium. 

Brown sugar also contains magnesium, choline, and phosphorus, whereas sugar lacks these. At the same time, sugar has less sodium. In a 100g serving, brown sugar and sugar have 28mg and 1mg of sodium, respectively.

Glycemic Index

Compared to sugar, brown sugar has a higher glycemic index value. The glycemic index of brown sugar is 71, whereas sugar has a glycemic index of 65. Brown sugar falls in the high-GI food category, whereas sugar is medium-GI food.

Acidity

The PRAL number indicates the food's capacity to degrade into bases or acids within the body. The PRAL level for brown sugar is -3.9 (alkaline). Sugar has a PRAL of -0.1 (neutral).

Antioxidant Activities

The polyphenolic contents of sugar and brown sugar, such as flavonoids, polyphenols, and phenolic acid, are responsible for their antioxidant action. Nevertheless, brown sugar's antioxidant value is higher (1, 2, 3).

Nervous System

Consuming high amounts of sugar may increase the production of free radicals in the brain and adversely affect the nervous system.

Due to their effects on blood levels of BDNF (brain-derived neurotrophic factor), high brown sugar and sugar intakes are not recommended. BDNF is involved in neuronal survival and development, neurotransmitter modulation, and neuronal plasticity, which is necessary for learning and memory. White sugar is more effective than brown sugar at decreasing serum BDNF levels (3).

Diabetes

According to the study, consumption of sugar and brown sugar has an adverse effect on insulin resistance. Insulin resistance is estimated using the homeostatic model assessment for insulin resistance (HOMA-IR) algorithm. Compared to the control group, sugar and brown sugar have substantially higher HOMA-IR values (3).  

Excessive intake of sugar also can deteriorate the management of diabetes (4).

Obesity

Overall, long-term sugar consumption may raise the risk of obesity and other related disorders. The group that consumed white sugar gained more weight than the group that consumed brown sugar (3).

Cancer

Sugar may be a modifiable risk factor for cancer prevention (5). 

Phenolics such as tricin and apigenin have antiproliferative and chemopreventive properties (2).

According to the study, brown sugar consumption is linked to a lower risk of stomach and breast cancer (6).

Cardiovascular Health

Section reviewed by cardiologist Astghik Grigoryan

Consuming excessive amounts of sugar is strongly discouraged, especially for individuals who have cardiovascular diseases. It significantly increases the risk of cardiovascular diseases and accelerates atherosclerosis by reducing HDL and triglyceride levels (4).
