This is what happens if you eat 14 g goji berries every day
If you eat 14 g goji berries every day for six weeks your waist measurement will decrease by a few centimetres. Your cholesterol balance will also improve and the concentration of antioxidants in your blood will increase. Brazilian researchers at the Universidade do Oeste de Santa Catarina discovered this when they did an experiment with 50 participants. Their study was published in Oxidative Medicine and Cellular Longevity.
The researchers did an experiment with 50 people whose insulin balance was suboptimal. Most of them were overweight, had high cholesterol levels and were on medication. All participants were advised to eat more healthily.
The researchers gave half of the participants 14 g goji berries to eat each day. The experiment lasted 45 days. The researchers examined the participants just before the experiment started, on day 15 and on the last day too.
Supplementation with goji berries [white bars] had no effect on 'good cholesterol' HDL but did lower the concentration of 'bad cholesterol' LDL, and the 'really bad' cholesterol VLDL [and therefore also the triglycerides in the participants' blood]. Black bars = control group.
The goji berries had no effect on the fasting glucose level of the participants, however.
The concentration of antioxidants in the blood increased in the goji berry-eating group. The same happened to the concentration of the antioxidant enzymes GSH and catalase. The goji berries also lowered TBARS, a marker of oxidant activity.
The concentration of the liver enzymes AST and ALT also decreased slightly in the goji berry group. It appears that goji berries have a protective effect on the liver.
The goji berries had no effect on the participants' bodyweight, but did reduce their waist measurement, probably because they reduced the amount of abdominal fat. Large amounts of abdominal fat are unhealthier than subcutaneous fat and raise the likelihood of developing all sorts of chronic diseases.
"The results of this study demonstrated an increase in serum antioxidant capacity and GSH and a decrease in lipid peroxidation, LDL cholesterol, and waist circumference after long-term ingestion of goji berries, suggesting that this is an effective dietary supplement for the prevention of cardiovascular diseases in individuals with metabolic syndrome following a free diet," the researchers concluded.
