Oily, fatty fish such as herring, wild or organic salmon, mackerel and trout contain the essential omega-3 fats that are proven to sharpen your mind. In fact, blood levels of omega-3s in newborn infants correlate with their IQ at the age of five.
If you don’t like eating fish, supplement an omega-3-rich fish oil every day, for you and your children.
Eggs contain phospholipids that also help improve memory and concentration. Don’t fry them, as this destroys the valuable nutrients, and always go for organic or free range.
