Ötzi's DNA is most similar to modern-day Sardinians.

A new study of the genetic history of Sardinia... tells how genetic ancestry on the island was relatively stable through the end of the Bronze Age, even as mainland Europe saw new ancestries arrive. The study further details how the island's genetic ancestry became more diverse and interconnected with the Mediterranean starting in the Iron Age, as Phoenician, Punic, and eventually Roman peoples began arriving to the island.
The people of Sardinia have long been studied by geneticists to understand human health. The island has one of the highest rates of people who live to 100 years or more, and its people have higher than average rates of autoimmune diseases and disorders such as beta-thalassemia and G6PD deficiency. Many villages in Sardinia also have high levels of relatedness, which makes uncovering the genetics of traits simpler. Across the island, the frequencies of genetic variants often differ from mainland Europe. These factors have made Sardinia a useful place for geneticists like senior author Francesco Cucca from the Università di Sassari in Italy to uncover genetic variants that may be linked to disease and aging.
The results also show the development of Sardinia's distinctive nuraghe stone towers and culture (after which the Nuragic period is named) did not coincide with any detectable, new genetic ancestry arriving to the island.
The group's results help explain similarities with DNA from mainland European individuals of the Neolithic and Copper Age, such as "Ötzi the Iceman," an almost perfectly preserved, 5,300-year-old human discovered in alpine ice in northern Italy in 1991. Specifically, among modern Europeans, Ötzi's DNA is most similar to modern-day Sardinians. The new study supports the theory that this similarity remains because Sardinia had less turnover of genetic ancestry over time than mainland Europe, which experienced large-scale migrations in the Bronze Age.

It’s the sardines that give them longevity.
I offer my kids sardines or anchovies and they look crooked at me and say “no, I don’t eat bait”
