A small daily amount of olive oil, roughly half a tablespoon to two tablespoons, is tied to real cardiovascular and brain health benefits.
A Harvard analysis of more than 92,000 adults followed for 28 years found that people who took in more than 7 grams of olive oil daily had a 28 percent lower risk of dementia related death regardless of the overall quality of their diet.
Drinking it straight, such as taking a morning shot, does not add extra benefit over using the same amount in cooking or on food.
