Apples are rich in soluble fiber pectin, polyphenols and natural antioxidants that are closely related to metabolic health, including regulating blood sugar, cholesterol levels and reducing inflammation - key factors affecting kidney function.
Soluble fiber helps bind excess metabolic products and cholesterol in the intestines, thereby reducing the load on the digestive system and reducing the kidney's blood filtration burden.
US nutrition experts also emphasize that apples contain polyphenols - a group of plant compounds with biological activity that contributes to protecting cells from oxidative stress and inflammatory reactions.
Apples contain soluble fiber and antioxidants that play a role in reducing blood sugar and post-eating cholesterol levels - two factors related to kidney dysfunction if prolonged.
When blood sugar and cholesterol are well controlled, the metabolic and blood filtration burden of the kidneys also decreases, helping the kidneys function more efficiently.
Apples are rich in soluble fiber, which helps the digestive system function smoothly, thereby promoting digestion and eliminating waste through feces and urine.
When the digestive system is "gentle", the kidneys also have less to process difficult-to-digest metabolic products, reducing pressure on the filtering mechanism of this organ.
A systematic study conducted in Taiwan with thousands of adults showed that consuming a lot of vegetables and fruits is associated with the slowdown of kidney function over time, meaning that the group that ate a lot of fruit (including apples) had a lower risk of kidney filtration function than the group that ate less vegetables and fruits.
To optimize the benefits of apples:
Eat the whole skin instead of just eating the flesh, because the skin contains the most polyphenols and fiber.
Eat fresh apples daily, a medium-sized apple is a reasonable portion.
Apples can be combined in breakfast or snacks with unsweetened yogurt, oats, and vegetable salad to increase fiber and nutrients.
Although apples are safe fruits for most people, people with severe gastrointestinal stenosis or stomach problems when eating a lot of fiber should start with small amounts for the body to adapt.
