Whole foods don't contain preservatives, chemicals or pesticides that change their makeup or growth process, and are as close to their natural state as possible. Whole foods are often more expensive than other types, but many people find the health benefits worth the extra cost.
Those who wish to maintain a healthy, organic diet can do so by consuming only whole foods. Whole foods contain more nutrients and less filler than preservative-rich counterparts.
A balanced diet of organic fruits, vegetables and beans contain the fiber a person needs without the aid of oral supplements. Substitute whole grains for refined grains as often as possible for optimal nutritional benefits. For example, brown rice and whole-wheat bread contain more minerals and vitamins than white rice or bread.
Lean meats from grass-fed animals contain higher amounts of omega-3 fatty acids and are more flavorful than meat from grain-fed animals raised on larger farms. Meat from grass-fed animals is also less likely to contain E. coli and other dangerous bacteria that may compromise a person's health after consumption.
Individuals can purchase whole foods from specialty stores or, in some cases, directly from the farms from which they originate. Whole foods contain nutritious components that can help prevent various diseases in humans and help them live a longer and healthier life.
