Zeaxanthin is one of the two main types of carotenoids present in the central part of the eye’s retina, in the macula.
Together with lutein, zeaxanthin plays an important role in maintaining eye health and protecting them from the effects of high-energy blue light and oxidative stress.
Zeaxanthin, along with lutein, act as natural sunscreens, absorbing certain wavelengths of light and preventing their negative impact on the eye’s photoreceptors.
Thus, they help maintain visual acuity and prevent age-related eye diseases such as macular degeneration and cataracts.
Zeaxanthin is found in many foods, especially in green leafy vegetables, yellow and orange fruits.
Below is a list of foods high in zeaxanthin:
In the context of the ketogenic diet, it is important to note that not all sources of zeaxanthin are equally suitable.
For example, fruits that are good sources of zeaxanthin contain sugar and carbohydrates, which can be a limiting factor for people following the keto diet.
Instead, attention should be paid to zeaxanthin-rich vegetables with low carbohydrate content, such as spinach and kale.
Eggs are also an excellent source of zeaxanthin and fit well into a keto diet regimen.
