Goji Berries: A Promising Weapon Against Macular Degeneration?

This study investigated whether eating Goji berries could help people with early age-related macular degeneration (AMD). AMD is a common eye disease that affects central vision, especially as we age.

Link to the study:

Macular pigment and serum zeaxanthin levels with Goji berry supplement in early age-related macular degeneration - PMC (nih.gov)


The Experiment:

- Researchers recruited 114 patients with early AMD, aged 51 to 92.
- Half the group (57 people) received a daily supplement of 25 grams of Goji berries for 90 days.
- The other half (57 people) continued their regular diet for 90 days (control group).

What They Measured:

Macular pigment: A light-filtering layer in the eye that helps with sharp vision. They measured its density using a special light test.

Serum zeaxanthin and lutein: These are pigments found in Goji berries and other foods, important for eye health. They measured their levels in the blood.

Visual acuity: This is how well you see at a distance, measured with a standard eye chart.


The Results:

- Goji berry intake significantly increased levels of serum zeaxanthin in the blood compared to baseline and the control group.
- Goji berries also led to a thicker macular pigment layer in the eye compared to baseline and the control group.
- However, Goji berries did not affect levels of serum lutein or improve visual acuity scores.

What This Means:

- Eating Goji berries for 3 months seems to increase levels of a key eye health pigment (zeaxanthin) in people with early AMD.
- This increase is linked to a thicker macular pigment layer, which might help protect against AMD progression.
- More research is needed to confirm these findings and see if Goji berries actually improve vision in the long run.

Important Notes:

This study was relatively small, so larger studies are needed for confirmation.

Goji berries may not be suitable for everyone, so consult your doctor before starting any supplements.

Overall, this study suggests that Goji berries hold promise as a natural way to support eye health in people with early AMD. However, more research is needed before they can be recommended as a standard treatment.
