Healthy Eating Tips – Top 10 Most Filling Foods

Just found this article on the Top 10 most filling foods - thought it might be of use. One thing I notice is that people who come into my clinic are rarely satisfied after they eat and so tend to then crave sweet things afterwards. Try eating meals that have both some form of protein (nuts and seeds, beans and lentils, eggs or lean meat) and some form of whole grain carbohydrate (brown rice, wholewheat pasta, quinoa or brown bread) and you'll notice those cravings reduce!

We all know we need to eat less to lose weight but doing so can be much harder ‘said’ than ‘done’ when hunger pangs, food cravings and the irresistible urge to snack takes hold.  That’s why the ‘Satiety Index’ developed by experts at the University of Sydney really can be a dieters best friend.

What is the ‘Satiety Index’?

At its simplest, the satiety index, is a measure of how long a particular food will stop you from feeling hungry.  It was first developed by Dr Susanne Holt back in 1995.  Holt and her colleagues fed volunteers 240 calorie portions of a wide variety of different foods in an attempt to discover which would be the most filling.  The foods were served from under a hood to minimize the influence of appearance, and, if possible, they were served at the same temperature and in the same size chunks.
After eating, the volunteers told the researchers what their appetite ratings were, but they were not allowed anything else for the next two hours. Then, after two hours, they were allowed to eat from a small buffet where the scientists measured how much they nibbled from a variety of other foods. Their consumption was closely monitored, and every 15 minutes they were questioned about their hunger to see if their subjective impression of satisfaction matched their eating behaviour. Using this information, Holt and her colleagues were able to put together the satiety index .  White bread was taken as the baseline of 100 and other foods were scored on their comparative ability to satisfy hunger.  Foods scoring higher than 100 were more satisfying than white bread whereas those scoring under 100 were less satisfying.

So, what are the top ten most filling foods?

1.    Potatoes (323% more satisfying than white bread)
2.    Fish (225%)
3.    Porridge/Oats/Oatmeal (209%)
4.    Apples (197%) and Oranges (202%)
5.    Wholewheat Pasta (188%)
6.    Beef (176%)
7.    Beans (168%)
8.    Grapes (162%)
9.    Wholemeal Bread (157%)
10.   Popcorn (154%)
What Makes These Foods So Filling?

Protein

Protein has been shown by numerous studies to be one of the most satiating nutrients.  Scientists at the National Institute for Medical Research in France have recently discovered that during its digestion, glucose is produced in the small intestine. The liver senses this and relays a message to the brain to slow down or stop eating — an effect that lasts well after the food has been swallowed.

Fibre

Unlike protein, fibre promotes satiety by slowing the rate at which the food is actually digested.  It also triggers stretch receptors in the stomach which automatically sends a signal to the brain to stop eating.

Water Content

Foods with a high fluid content such as apples, oranges and grapes also trigger thestretch receptors however, they are mostly made of water and sugars therefore the speed at which they are digested means that, unlike most other high S.I foods initial feelings of fullness can drop of fairly quickly.  “This is why” explains Dr Holt “ that when a dieter eats a meal based on several pieces of fruit and some rice cakes (also very quick to digest) they invariably feel ravenous a few hours later.  Despite the meal being low in fat and calories it isn’t at all filling.  Far better to eat a wholesome salad sandwich on wholegrain bread with some lean protein like tuna or beef and an apple. This kind of meal can keep hunger at bay for a very long time."

Volume

Another thing that increases a food’s S.I rating is its bulk.  Popcorn for example only contains 55 calories per cup but it takes up a lot of space in the stomach helping to create the feelings of fullness.  Fat on the other hand is the exact opposite.  At 9 Kcal per gram fat is the most energy dense nutrient we can eat.  Just one tablespoon of clotted cream has almost four times more calories than a whole cup of popcorn and yet it takes up far less space in the stomach making it incredibly easy to over consume.  Fat greatly enhances the taste of a food too, another reason why we find it so easy to over consume.

Chemical Compounds

The chemical constituents of foods can also make a difference to satiety.  Beans and lentils, for example, contain anti-nutrients which delay their absorption.  Another reason why they have a tendency to make you feel full for longer.

Chewing

Chewing promotes satiety, partly because it slows down eating but also because it encourages the release of enzymes that register fullness in the brain.
