A diet rich in olive oil, vegetables, potatoes, legumes, blue fish, pasta, and meat seems to counteract frailty onset in older people. A Spanish study on 1872 non-hospitalized older people (60 years of age or more) has assessed the correlation between dietary habits and the frailty onset. Two dietary patterns were identified: the first was called the “prudent” pattern due to the high consumption of olive oil, vegetables, potatoes, legumes, blue fish, pasta, and meat; and the second was called the “Westernized” pattern because of the high consumption of refined bread, whole dairy products, and red and processed meat, as well as the low intake of whole grains, fruit, low-fat dairy, and vegetables. In older adults, a “Westernized” pattern showed a direct relationship with some components of frailty, while a “prudent” dietary pattern seemed to have a protective effect against frailty.
