SUPERFOODS AND HEALTH caspian
Superfood is used to describe food with high nutrient or phytochemical content that may confer health benefits, with few properties considered to be negative, such as being high in saturated fats or artificial ingredients, food additives or contaminants.
An often-cited example of a superfruit is blueberries which contain moderate-rich concentrations of anthocyanins, vitamin C, manganese, and dietary fiber, pterostilbene (an undefined phytochemical under preliminary research) and low calorie content. Other examples of superfoods include broccoli, spinach, pumpkin and tomatoes which are rich in various nutrients.
All these fruits and
vegetables contain a variety of nutrients and
Citations for superfood in the general sense of "a food considered
especially nutritious or otherwise beneficial to health and

Nutrition in the August edition of 1998, which stated, "Humans have
many options when it comes to fueling their bodies, but the benefits
of some options are so nutritious that they might be labeled as
Many recent superfood lists contain common food choices whose nutritional value has been long recognized. Examples of these would be berries, nuts and seeds in general, dark green vegetables (such as kale, collard greens, Swiss chard, Brussels sprouts and broccoli), citrus fruits, fatty fish such as salmon, mackerel and sardines, vegetables with bright, dark or intense colors (such as beets and their greens, and sweet potatoes), many legumes (peanuts, lentils, beans (with some beans being significantly higher in certain nutrients than others)), and whole grains as a group. Possibly the most studied superfood group, berries, remain under scientific evaluation.
For example, green tea and its extracts have been studied over decades for their potential benefits, including possibly weight loss, as well as for polyphenol content that might supply other potential benefits. Many weight loss supplements contain green tea extracts as a key ingredient, due to a tea flavanol called epigallocatechin gallate (EGCG).
