Preheat your oven to 350°F (175°C). Grease a loaf pan.
In a mixing bowl, combine flour, sugar, baking powder, and salt.
In another bowl, whisk together eggs, milk, oil, lemon zest, and lemon juice.
Pour the wet ingredients into the dry ingredients and mix until just combined.
Gently fold in the blueberries.
Pour the batter into the prepared loaf pan.
Bake for 60 minutes or until a toothpick inserted into the center comes out clean.
Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
