Multiple Choice Question Sunlight is the best source of vitamin D. However, if you cannot spend enough time in the sun to synthesize adequate vitamin \( D \), which of the following is the best dietary strategy to obtain vitamin D? Eat a serving of fatty fish twice per week. Eat one cup of fresh berries each day. Drink one cup of black coffee each day. Eat one serving of green, leafy vegetables every day.

Eating a serving of fatty fish twice per week is indeed one of the best dietary strategies to obtain vitamin D. Fish like salmon, mackerel, and sardines are not only delicious but also packed with this essential vitamin, making them a fantastic choice for those who may not get enough sun exposure. Plus, they’re a great source of omega-3 fatty acids, which are beneficial for your heart and brain! For those who think fresh berries or coffee might help, it's important to remember that while these options are healthy, they don't contain significant amounts of vitamin D. Berries are fantastic for antioxidants and vitamins, and coffee has its own set of benefits, but they won't do the trick for your vitamin D levels. So, stick to that fish and keep your body happy and healthy!
