Low glycemic for eye health -
In early stages, AMD results in blurred vision. In advanced stages, AMD can make life very challenging. The National Eye Institute estimates that the number of people with AMD will double by , from 2. In the United States, white Americans are most likely to develop AMD and, in , 2.
The disease is typically diagnosed only when vision loss has already begun. Unfortunately, there is no cure.
Using an aged mouse model, the researchers randomized 59 mice into two groups: 19 low-glycemic fed mice and 40 high-glycemic fed mice. The diets differed only in carbohydrate source. Carbohydrates comprised 45 percent of the diet in both cases. The carbohydrate source varied in the ratio of amylose and amylopectin, the two starches used for this work.
The high-glycemic starch was percent amylopectin while low-glycemic starch was 70 percent amylose and 30 percent amylopectin. After six months, the high-glycemic group of mice either remained on the high-glycemic diet or were switched to the low-glycemic diet. The researchers observed that a high-glycemic diet resulted in the development of many AMD features, including loss of function of cells at the back of the eye called retinal pigmented epithelial atrophy RPE and of the cells that capture light, called photoreceptors — precursors to dry AMD — whereas a low-glycemic diet did not.
Importantly, switching from a high-glycemic diet to a low-glycemic diet arrested damage to the retina. The researchers also identified potential biomarkers of AMD features.
Such biomarkers can be used to predict who will get the disease. The biomarkers included advanced glycation end products AGEs that are formed when sugar metabolites react with proteins. They also included oxidized fats, C3-carnitine and serotonin levels.
The low-glycemic diet limited the accumulation of AGEs and the oxidation of long-chain polyunsaturated fats. AGEs can be a factor in aging and the development of many degenerative diseases, in addition to AMD. Fat oxidation results in the degradation of fats in cell membranes, which can lead to cell damage.
The researchers also found that higher levels of C3-carnitine and serotonin in the blood were related to consuming the low-glycemic index diet and less AMD features. C3-carnitine, also known as propionylcarnitine, plays a role in fatty acid metabolism in cells and is found in many low-glycemic foods, such as whole wheat and legumes.
Serotonin is made in the intestine, in response to signals that are produced by microbes in the gut. The researchers showed that the composition of gut microbes, collectively called the gut microbiome, changes in response to the diet. Higher serotonin levels are associated with retinal health and reduced frequency of AMD features.
The researchers identified several other metabolites that were associated with protection from AMD and with the composition of the gut microbiome, which together led the authors to speculate on a potential gut-retina axis that may communicate diet to eye health. Altogether, the findings suggest that changes in metabolism associated with the different glycemia diets, AGEs accumulation, production and oxidation of fats, and C3-carnitine and serotonin levels are related to development of AMD features.
These findings add to a growing body of research on the relation between dietary carbohydrate control and the development of AMD, led by senior author Allen Taylor, Ph. Our findings show an interaction between dietary carbohydrates, the gut microbiome, specific biochemical molecules, and AMD features.
This work should lead to new approaches to understand, diagnose and treat early AMD — perhaps before it affects vision. A screening of C3-carnitine levels is a standard part of the newborn screening profile, so it would not be challenging to adapt the existing screening to evaluate levels in AMD.
Recently, an eye doctor at New York Eye and Ear Infirmary of Mount Sinai NYEE conducted a unique research study exploring the potential link between long-term dietary changes and preventing primary open angle glaucoma POAG.
These results were published in Eye-Nature July 22 issue. Many eye diseases can be quickly and easily diagnosed during a Comprehensive eye exam , Pediatric eye exam and Contact lens eye exam.
If you were diagnosed with an eye disease, such as Myopia or Nearsightedness , Cataracts , Glaucoma , Macular degeneration , Diabetic retinopathy , or Dry eye , you may be overwhelmed by the diagnosis and confused about what happens next. Will you need medications or surgery — now or in the future?

Currently, glaucoma is the 1 cause of blindness in the United States, and primary open-angle glaucoma is the most common type of this dangerous eye disease. Due mainly to elevated pressure levels inside the eye, POAG leads to optic nerve degeneration — causing vision loss.
Usually, patients experience no symptoms of POAG until the disease progresses, and visual problems motivate them to visit a nearby eye clinic for an eye exam.
In addition to routine eye exams, following a low carb diet may fortify people with another way to help prevent devastating vision loss.
Eating foods that are low in carbohydrates and higher in fats and proteins causes the production of metabolites that are favorable for the optic nerve head, which is the specific site of damage in primary open-angle glaucoma.
While the low-carb diet cannot stop glaucoma progression in a patient who already has the disease, it may be a helpful way to prevent glaucoma in high-risk groups, such as people with a family history. Subsequently, the rate of vision loss due to glaucoma would be reduced.
Does a low-carb diet have the same effects as a ketogenic diet? In the past, studies have demonstrated the protective effects that a ketogenic diet can have against neurologic disorders. However, additional studies have shown that following a low-carb diet, not specifically ketogenic, may have similar properties for protecting against neurologic problems.
