Meal replacement means that instead of eating a meal or snack, you replace it with the formulated product. Generally these products are marketed towards convenience and specific dietary related functions. However they all contain considerable risks to health if not consumed in moderation (meaning occasionally, not the majority of the diet). Proper nutrition requires ingestion and absorption of fibre, vitamins, minerals, and food energy in the form of carbohydrates, proteins,vegetable oils, and fats. These types of products also tends to be quite high in chemical additives.
Beverages and Bars With modern Australians becoming more and more busy, meal replacement beverages and and bars are becoming more common.
Weight Control Products The food market has an abundance of weight and diet control products available today. Some meal-replacement products, such as milk shakes, soups, bars and powders claim to aid weight loss.
Whilst weight loss may occur initially, these types of diets are difficult to sustain and can become boring. The dieter does not learn how to make healthier food choices and eventually re gains the weight when they return to their usual diet. There are also a range of meal replacement products, aimed mostly at men, which are promoted to increase body mass and muscle due to their high protein, vitamin and mineral content.
There are health concerns about meal replacement products as excessive intake of some vitamins and minerals may be dangerous and excess protein can be stored as fat.
Snack Bars Snacking is an important part of the diet, and traditionally snacks were considered to be a piece of fruit, or ingredients that were commonly available in the home, such as leftovers. Research now indicates that Australians are replacing meals with snacks.
With the trend of convenience, packaged snack foods are now a significant business. Snack foods are typically designed to be portable, quick and satisfying. Processed snack foods are designed to be less perishable, more durable, and more portable than prepared foods. They often contain substantial amounts of sweeteners, preservatives, and appealing ingredients such as chocolate, peanuts, and specially-designed flavors (such as flavored potato chips).
Snack foods are often subjectively classified as junk food because they typically have little or no nutritional value,and are not seen as contributing towards general health and nutrition. With growing concerns for diet, weight control and general health, government bodies are recommending that people make a conscious effort to eat more healthy, natural snacks – such as fruit, vegetables, nuts and cereal grains – while avoiding high-calorie, low-nutrient junk food.
A 2010 study showed that children in the United States snacked on average six times per day, approximately twice as often as American children in the 1970s.
Electrolyte Replacement Drinks Electrolyte replacement drinks are designed to help athletes rehydrate and replace electrolytes (sodium, potassium, chloride) and salts that have been lost through sweating during training or competition. Whilst these drinks were originally intended for athletes, they are now also promoted to the general public. They come in an array of colours and flavours to appeal to young people. These beverages should be drunk in moderation as they contain high amounts of glucose, to provide energy, but also large amounts of electrolytes such as sodium can contribute to health problems such as hypertension.
