Do Black people that take care of themselves, by that I mean don't Smoke, Drink, and eat unhealthy foods live longer than someone of another race? The reason I ask this question is because I was browsing through the oldest people to ever live, and out of the top ten, three were Black American. A lot may say that is not many, But when you think about the fact that the united states has less than 5% of the worlds population, and Black american only make up about 12% of that, How can there be such a large amount? Does it have something to do with the melanin in Black people skin or something? For most of them the odds were against them being born in the 1800s segregated south. Seems like they would not live as long.

The predominant theory is that the race of man was originally dark skinned as that afforded them the greatest protection from the sun in the original territory of the grasslands of Africa. As man migrated around the globe there was a strong movement toward the higher latitudes of Europe and Asia. The peoples in Asia tended to eat more fish and remained dark.

The people in Europe did not eat fish regularly, and lack of vitamin D made them die early. White skin is actually "clear skin" as all humans and apes and chimpanzees have white layers beneath their epidermis or fur. The clear skin allows the lower layers to convert vitamin D from the sun more easily. But the downside is the increased incidence of skin cancer. But evolution does not care about diseases that tend to affect a species past breeding age.

But these differences in longevity would not apply in the modern world where natural factors take a backseat to manmade ones. It is possible that given conditions in the early 20th century, more black people were exposed to a greater number of childhood diseases, and a less rich diet consisting of more beans and vegetables. So while the life expectancy of a black person in the late 1890's was very low compared to a white person, the black people that livee for 100 years and more are more resistant to disease.

No, we are all human and the color of your skin does not affect your internal genealogy.

African American life expectancy at birth is persistently five to seven years lower than European Americans. African Americans have higher rates of mortality than does any other racial or ethnic group for 8 of the top 10 causes of death. The cancer incidence rate among African Americans is 10% higher than among European Americans.

The OP had a reasonable question. In general white skin was not a characteristic chosen by natural selection to prolong life, it provides for a healthier child bearing age in non-tropical climates that had less sunlight. Absent any other factors, white skin generally shortens life because of increased skin disease.

Now ten thousand years ago, the probability of living to an old age was minimal. Despite the best food and care, the first monarch of England or Great Britain to live past the age of 70 only died 250 years ago.
