Within the video above, Dr. Eric Berg, a chiropractor and well being educator, opinions what he believes are among the finest pure alternate options to stop and/or deal with cataracts.
Cataracts1 is a watch situation that causes your imaginative and prescient to blur as a result of a buildup of proteins on the lens of your eye. Left untreated, cataracts may end up in progressive lack of imaginative and prescient and, in the end, blindness.
Danger components for cataracts embody heavy alcohol use, smoking, older age, diabetes, poisonous substances, sure drugs and trauma to the attention.2 Indicators and signs that cataracts are forming embody:3,4
Blurry, cloudy or foggy imaginative and prescient
Modifications in shade notion
Problem driving at night time as a result of glare from lights

Cataract Surgical procedure Is Not Danger-Free
The most typical remedy for cataracts is surgical procedure, however as famous by Berg, it’s not with out dangers. In 42% of instances, cataract surgical procedure leads to dry eyes, and in 20% of instances, it leaves the affected person with a droopy eyelid. Different potential unintended effects embody floaters, retinal detachment, eye an infection, glaucoma, additional imaginative and prescient loss and secondary cataracts.5
Like Berg, I might strongly encourage making an attempt a number of pure cures earlier than resorting to surgical procedure. He factors out that scientific proof displaying the efficacy of pure cures are usually scant, however that doesn’t imply they’re ineffective. The rationale for this lack of scientific proof is as a result of few are keen to speculate the funds required to check a compound that can by no means flip a revenue.
You can not patent meals or pure vitamins, for instance, and dietary supplements don’t maintain a candle with respect to profitability in comparison with medication. You can not cost tons of or 1000’s of {dollars} for a bottle of dietary supplements. However, the chance you are taking by making an attempt a pure treatment is close to nonexistent.
Including extra vitamins to your weight loss plan just isn’t going to harm you. At worst, you received’t see a profit. Understand that after we’re speaking about meals, and even dietary supplements, it’ll usually takes a number of weeks or months earlier than results develop into noticeable, so stick with it lengthy sufficient to make a distinction.
Your Eyes Are Affected by Blood Sugar
As defined by Berg, your eyes are considerably affected by blood sugar. Chronically excessive blood sugar from poor vitamin and lack of train can set off long-term harm to your physique and make you extra vulnerable to eye illnesses, together with cataracts, glaucoma and blindness.6,7,8 Berg explains:9
“When your blood sugar is excessive, it creates a number of oxidative stress in several tissues, together with the eyes. Our our bodies produce [endogenous] antioxidants to guard towards this oxidation and free radical harm. However sure issues, like age and weight loss plan, may cause our our bodies to make fewer antioxidants.
Nevertheless, vegetation additionally make potent antioxidants that we will make the most of to assist counter the consequences of oxidative stress. The 2 classes that we’re specializing in as we speak are carotenoids and anthocyanins.”
Carotenoids and Anthocyanins Assist Eye Well being
Carotenoids and anthocyanins are pure pigments present in fruits, berries and greens. Meals excessive in carotenoids embody yellow, orange, purple and purple vegatables and fruits, pasture-raised egg yolks and grass-fed meats.
Key carotenoids identified for his or her protecting results on eye well being embody beta-carotene (a precursor for vitamin A), lutein, zeaxanthin and astaxanthin. I’ll evaluate among the advantages and mechanisms of motion of lutein and astaxanthin additional beneath.
Antioxidants present in leafy greens and colourful berries and greens might help forestall and/or deal with cataracts. Key vitamins embody carotenoids like lutein, zeaxanthin, astaxanthin and vitamin C.
Meals excessive in anthocyanins are purple, purple and blue, corresponding to bilberries, blueberries, blackberries, chokeberries, black currant and purple cabbage (particularly purple cabbage sprouts), simply to call just a few. Berg’s selfmade cataract treatment is a once-daily shake consisting of:
1 cup purple, purple or blue berries of your selection
1 cup kefir (grass-fed, complete milk, unsweetened)
Kefir incorporates calcium and probiotics, each of that are considered protecting towards cataracts. Combine the 2 elements in a blender and both devour with a spoon or add a small quantity of water to make it simpler to drink. Additionally, devour a weight loss plan that’s low in fructose, sucrose and different sugars, together with lactose from milk, to stop persistent elevations in blood sugar.
Antioxidant Eye Drops for Cataracts
Different pure cures for cataracts talked about by Berg embody N-acetylcarnosine (NAC) drops. This shouldn’t be confused with N-acetylcycsteine, which is also called NAC. N-acetylcarnosine has been proven to penetrate your cornea into the lens of your eye, the place the cataract is positioned.
There, the NAC is metabolized into L-carnosine, which has an antioxidant impact on the cataract-affected lens. Based on a scientific evaluate by the Cochrane Library,10 “NAC eye drops could reverse and even forestall development of cataract, thereby enhancing imaginative and prescient and high quality of life.”
A 2017 research11 additionally discovered that N-acetylcysteine amide (NACA) drops had been efficient in reversing cataracts, whereas a 2022 research12 concluded oxysterol, an oxygenated ldl cholesterol spinoff, successfully reversed cataracts in mice. As reported by Medical Information Right now:13
“The researchers used oxysterol to aim to change the degrees of alpha-crystallin B or alpha-crystallin A proteins current within the lenses of 26 mice. These proteins typically trigger cataracts to develop in growing older.
The research confirmed that oxysterol improved lens opacity 61% of the time. It is a promising signal that oxysterol could also be an efficient, nonsurgical remedy for cataracts.”
Lutein Protects Towards Eye Illnesses
As talked about earlier, lutein is a carotenoid that’s actually vital for eye well being and helps to guard towards not solely cataracts but additionally glaucoma and age-related macular degeneration (AMD), which is the No. 1 reason for blindness within the aged.
Lutein concentrates in your macula, which is the a part of your retina liable for central imaginative and prescient. Together with zeaxanthin and mesa-zeaxanthin (a metabolite of lutein), these three carotenoids type the retinal macular pigment, which not solely is liable for optimizing your visible efficiency but additionally serves as a biomarker for the chance of macular illnesses.14
Lutein can also be discovered within the lens, the place it helps defend towards cataracts and different age-related eye illnesses. Amongst carotenoids, lutein is essentially the most environment friendly at filtering out blue gentle — the sort that comes from cellphones, computer systems, tablets and LED lights. Blue gentle induces oxidative stress in your eyes, which will increase the chance of cataracts and macular illnesses. Lutein, nevertheless, acts as a protect towards it.
Your physique can not make lutein, so you have to get it out of your weight loss plan. Following are 10 meals which can be notably wealthy sources of lutein.
Darkish leafy greens
Carrots
Broccoli
Egg yolks
Crimson and yellow peppers
Candy corn
Avocados
Raspberries
Cherries
Paprika
The phrase lutein comes from the Latin phrase “luteus,” which implies “yellow.” For those who bear in mind this, it might show you how to select greens more likely to include greater quantities.
Lutein and zeaxanthin are sometimes discovered collectively in meals, though zeaxanthin is way scarcer than lutein. Based on a 1998 research within the British Journal of Ophthalmology,15 orange pepper had the very best quantity of zeaxanthin of the 33 vegatables and fruits examined.
How A lot Lutein and Zeaxanthin Do You Want?
Whereas there is no really helpful every day consumption for lutein and zeaxanthin, research have discovered well being advantages for lutein at doses between 6 milligrams (mg) and 20 mg per day16,17,18 and a couple of mg per day for zeaxanthin.19
Analysis evaluating the impact of lutein, zeaxanthin and meso-zeaxanthin together, utilizing a dose of 10 mg of lutein, 10 mg of meso-zeaxanthin and a couple of mg of zeaxanthin per day for one 12 months, discovered it helped enhance imaginative and prescient in those that had regular imaginative and prescient on the outset.20
Optimize Lutein Absorption
Lutein and different carotenoids are fat-soluble, so to optimize absorption, be sure you add a bit little bit of wholesome fats to your meal. For instance, analysis exhibits that including a few eggs — which include each lutein and wholesome fat — to your salad can improve the carotenoid absorption from the entire meal as a lot as ninefold.21,22 Egg yolks are additionally a main supply of choline, which helps counter dry eye.23
Ideally, go for organically raised, free-range pastured eggs. Not solely do they have a tendency to have a greater dietary profile, by choosing pastured eggs you’ll additionally keep away from pesticide publicity and genetically modified organisms.
Most commercially obtainable eggs come from concentrated animal feeding operations (CAFOs), the place the hens should not permitted to forage on pasture. As a substitute, they’re usually fed a weight loss plan of corn and soy, the overwhelming majority of that are genetically engineered. CAFO eggs are additionally much more vulnerable to trigger foodborne sickness attributable to salmonella contamination.
For those who reside in an city space, visiting a neighborhood well being meals retailer is usually the quickest path to discovering high-quality native egg sources. Your native farmers market is one other supply for recent free-range eggs. Cornucopia.org additionally affords a useful natural egg scorecard24 that charges egg producers based mostly on standards which can be vital for natural customers.
You’ll be able to typically inform the eggs are free-range by the colour of the egg yolk. Foraged hens produce eggs with brilliant orange yolks, indicative of upper quantities of lutein and zeaxanthin. One other option to enhance absorption of lutein out of your greens is so as to add some uncooked natural butter or coconut oil to your salad.
Vitamin C Combats Cataracts
Different vitamins are additionally helpful for imaginative and prescient well being. As an illustration, vitamin C is related to a decrease danger of cataracts. One research25 in contrast vitamin C consumption and the development of cataracts in additional than 320 pairs of feminine twins over the course of a decade.
It discovered that those that ate extra vitamin C-rich meals lowered their danger of cataracts by one-third. Curiously, vitamin C dietary supplements weren’t related to a discount in danger.
Citrus fruits corresponding to kiwis, oranges, lemons, limes and grapefruits are well-known for being excessive in vitamin C, however the fruit with the very best focus of all is definitely acerola cherries (also called Barbados cherries). Every cherry has only one calorie, however 80 mg of vitamin C and related micronutrients.
Astaxanthin — The Most Highly effective Promoter of Eye Well being
Saving the perfect for final, astaxanthin is much more potent an antioxidant than each lutein and zeaxanthin, and lots of researchers consider it to be essentially the most highly effective antioxidant ever found for eye well being.26,27
Astaxanthin is produced by the microalgae Haematococcus pluvialis when its water provide dries up, forcing it to guard itself from UV radiation. In addition to the microalgae that produce it, the one different supply are the ocean creatures that devour the algae, corresponding to wild salmon, shellfish and krill.
It has been discovered to have protecting advantages towards a variety of eye-related issues, together with cataracts, AMD, cystoid macular edema, diabetic retinopathy,28 retinal arterial occlusion and venous occlusion, glaucoma,29 and inflammatory eye illnesses corresponding to retinitis, iritis, keratitis and scleritis.
Astaxanthin simply crosses into the tissues of your eye and exerts its results safely and with extra efficiency than any of the opposite carotenoids, with out opposed reactions. Particularly, astaxanthin has been proven to ameliorate or forestall light-induced harm, photoreceptor cell harm,30 ganglion cell harm and harm to the neurons of the interior retinal layers.
Astaxanthin additionally helps preserve applicable eye stress ranges which can be already inside the regular vary and helps your eyes’ vitality ranges and visible acuity. Relying in your particular person scenario, you might need to take an astaxanthin complement. I like to recommend beginning with 4 mg per day and dealing your approach as much as about 8 mg per day — or extra in the event you’re affected by persistent irritation.
Taking your astaxanthin complement with a small quantity of wholesome fats, corresponding to grass-fed butter, coconut oil, MCT oil or eggs, will optimize its absorption. Krill oil additionally incorporates prime quality animal-based omega-3 fats together with naturally occurring astaxanthin, albeit at decrease ranges than what you will get from an astaxanthin complement.
Different Pure Methods That Assist Defend Your Imaginative and prescient
Regardless of what your eye physician could say, for my part, there are pure, common sense methods you possibly can make use of to assist defend your wholesome imaginative and prescient, beginning together with your weight loss plan. As mentioned above, sure meals are roughly crucial for optimum imaginative and prescient and may go a great distance towards defending your eyesight all through life.
This contains leafy greens and brightly coloured greens, natural pastured egg yolks, black, blue and purple berries, and seafood wealthy in astaxanthin, such wild caught Alaskan salmon. In addition to these dietary strategies, listed below are just a few different way of life methods that may assist optimize your eye well being.
Keep away from blue gentle, corresponding to that from digital screens, as blue gentle reduces melatonin in your lens, which is an enormous trigger for cataracts. Avoiding blue gentle turns into much more vital if in case you have cataract surgical procedure, as your pure lens has some built-in safety towards blue gentle whereas the synthetic lens doesn’t.
(UV-blocking synthetic lenses can be found by means of particular order, nevertheless it’s not customary.) So, in the event you get cataract surgical procedure, put on blue-blocking glasses when taking a look at screens and when in synthetic lighting indoors.
Stop smoking — Smoking ramps up free radical manufacturing all through your physique and places you in danger for less-than-optimal well being in some ways. If you would like wholesome imaginative and prescient on your complete life, you can not afford to danger less-than-optimal eye well being with cigarettes.
Care on your cardiovascular system by getting common train — Hypertension may cause harm to the miniscule blood vessels in your retina, obstructing free blood movement. A daily train program can go a great distance towards lowering your blood stress. It’s additionally vital for optimizing your insulin and leptin ranges.
Normalize your blood sugar — As talked about earlier, chronically elevated blood sugar can harm your eyes and impede blood movement to your retina. To maintain your blood sugar in a wholesome vary, observe my complete vitamin pointers.
Keep away from seed oils and processed meals — Your eyes are extremely vulnerable to and broken by polyunsaturated fat (PUFAs) corresponding to linoleic acid (LA), so keep away from cooking with seed oils (a.ok.a. vegetable oils) and keep away from processed meals.
I’ve beforehand interviewed Dr. Chris Knobbe, an ophthalmologist who wrote a ebook on the historic development of AMD, displaying the way it rose in tandem with the consumption of seed oils. His conclusion is that seed oils or excessive doses of omega-6, particularly LA, had been the first perpetrator not simply in AMD however persistent illnesses of all types.
Keep away from aspartame — Imaginative and prescient issues are one of many many potential acute signs of aspartame poisoning.
