Different Glycemic Indexes of Breakfast Cereals Are Not Due to Glucose Entry into Blood but to Glucose Removal by Tissue.
This is another older paper that I wanted to talk about since it ties in somewhat with the feedback on milk below. In way of introduction, I should probably define glycemic index (GI) for readers who aren’t familiar with it.
The GI is used to rate carbohydrates by examining the blood glucose response to 50 grams of digestible carbohydrates. After fasting, subjects are first given some reference food; this used to be glucose but researchers now use white bread. The blood glucose response to white bread is defined as 100. Then, the test food is given and the blood glucose response is measured and compared to that of the test food. A food that shows 60% of the blood glucose response to white bread is given a GI of 60.
Milk as an Effective Post-Exercise Rehydration Drink
The effectiveness of low-fat milk, alone and with an additional 20 mmol/l NaCl, at restoring fluid balance after exercise-induced hypohydration was compared to a sports drink and water. After losing 1·8 (SD 0·1) % of their body mass during intermittent exercise in a warm environment, eleven subjects consumed a drink volume equivalent to 150 % of their sweat loss. Urine samples were collected before and for 5 h after exercise to assess fluid balance.
Extremely Limited Synthesis of Long Chain Polyunsaturates in Adults: Implications for Their Dietary Essentiality and Use as Supplements
In many, if not all, of my books, I tend to highly recommend that people take some form of preformed fish oils on a daily basis. For various reasons, either related to people not liking to swallow pills, or occasional vegetarian concerns, a question I often get is whether or not flaxseed oil can take the place of preformed fish oils in the diet. As well, there is often a great deal of confusion on various internet forums as to whether or not flax oil is an appropriate source of the essential fatty acids.
