To support a training session or competition athletes need to eat at an appropriate time so that all the food has been absorbed and their glycogen stores are fully replenished. High GI foods take 1 to 2 hours to be absorbed and low GI foods can take 3 to 4 hours to be absorbed. Glycogen stores will last for approximately 10 to 12 hours when at rest (sleeping) so this is why breakfast is essential.
For fifty years, scientists told us that too much saturated fat was bad for our hearts, and advised us to switch to polyunsaturated fats instead. It turns out that polyunsaturated fats are not all equal, and some of them actually increase the odds of cardiovascular disease and death. In this week’s Research Review, we’ll explore why mistaken conclusions in science can sometimes become accepted wisdom – and which fats you really should eat for better health. Ever notice how a particular food can become all the rage – only to drop out of fashion a few years later? And how the food or nutrient that our doctors told us to get more of in 1990 can morph into the one they are warning us against in 2013? With so much conflicting information out there, it can be tough to figure out what to believe. Keep that in mind as we explore the complicated world of fats and their role in heart health. In the last half of the 20th century, doctors and nutrition professionals agreed: too much saturated fat was bad for the heart. The recommendations were clear: If you want to avoid heart disease and keep your arteries free of build-up, you should increase polyunsaturated fats and decrease saturated fats in the diet.
And the type of polyunsaturated fat you eat may be just as important as how much of it you eat. For example, you’ll notice that naturally occurring saturated fats (such as coconut) are important in a healthy diet. Want to know why omega-3 fatty acids are special, check the Research Review: How do omega-3 fatty acids work? Are polyunsaturated fats bad for your heart?Every once and awhile a food or nutrient gets vilified. If you’re looking to add good fats to your diet, start with whole food-based fats in their natural, least-processed state. Unless you’re grinding and pressing your own olives or seeds, remember that all oils have undergone at least some processing.
The table below (source) breaks down the fatty acid composition of different types of oils that can be used for cooking – along with butter, for comparison. When you’re cooking, you want to prevent oil from burning because overheating causes chemical deterioration and produces toxic compounds that circulate in your body and lead to inflammation. Cooking with oils high in omega-3 fatty acids is a bad idea because these oils are especially sensitive to heat, and break down easily into trans fats.
To recap: For many years, conventional wisdom held that polyunsaturated fats were good for the heart. So what happens when people with coronary heart disease increase omega-6 fatty acids (linoleic acid) in their diets?
Ramsden CE, Zamora D, Leelarthaepin B, Majchrzak-Hong SF, Faurot KR, Suchindran CM, Ringel A, Davis JM, Hibbeln JR. The original Sydney Diet Heart Study involved a total of 458 men between the ages of 30-59, each of whom had suffered a recent “coronary event.” Coronary events included acute myocardial infarction (86%) and acute coronary insufficiency or angina (14%).
First, they ate more polyunsaturated fatty acids (PUFA), aiming to get about 15% of their daily calories from these fats.
Meanwhile, they reduced their saturated fatty acids to less than 10% of their daily calories and tried to keep dietary cholesterol to less than 300 mg per day. To get their PUFA intake up, researchers gave the men safflower oil and margarine (aka solid safflower oil) for their cooking needs. It wasn’t until the 1990s that eating margarine containing trans fats was linked to heart disease (2).
The authors of the original study (3) hypothesized that eating more polyunsaturated fat would contribute to lower levels of saturated fat in the diet.
Ultimately, they believed that this would reduce the incidence of cardiovascular and coronary disease and lead to lower death rates. In other words, one year into the Sydney Diet Heart Study, all findings supported the original hypothesis. By then, it had become clear that the intervention group was experiencing higher death rates, higher rates of cardiovascular disease and higher rates of coronary disease! How could a clear decrease in cholesterol be linked to higher rates of cardiovascular and coronary disease?
In the meta-analysis under review, the scientists scrutinized a number of other, similar studies to try to figure out what caused the increased death rates in this particular study. Their review of eight different papers revealed that the type of polyunsaturated fats used in an intervention seemed to be key.
Increasing omega-6 oils exclusively in an intervention seemed to lead to a higher risk of cardiovascular disease and death. Eating more polyunsaturated fats in the form of omega-6 fatty acids increases rates of death, cardiovascular disease, and coronary disease.


If you follow PN, the first conclusion – that eating more omega-6 fatty acids could increase the risk of disease – won’t come as a huge surprise. In the Sydney Diet Heart Study, researchers hypothesized that more polyunsaturated fats would decrease death due to cardiovascular and coronary disease, and that cholesterol is a good measure of predicting coronary disease. If you look at the data today, with the benefit of hindsight, it appears that hypothesis was wrong. But back in 1970, all other available data supported a diet low in saturated fat, high in unsaturated fat, and low in cholesterol. It’s almost impossible to publish data that refutes the accepted wisdom in a given period – especially if you have no plausible explanation for your anomalous results. With the advantage of 50 years further study and experimentation, we know that not all polyunsaturated fats are equal. Omega-6 polyunsaturated fats, in particular, can increase the risk of death from coronary disease – probably because they increase inflammation. But in 1970, scientists didn’t distinguish between the sub-types of polyunsaturated fat, and didn’t recognize that cholesterol is not a good measure for predicting coronary disease.
That’s why, in the end, it’s important to understand that science is a process. Knowledge builds over time. This is why we shouldn’t jump on every nutritional bandwagon; sometimes we need context to make sense of recent discoveries. The Sydney Diet Heart study revealed the uncomfortable truth that diets high in one type of fat (omega-6 fatty acids, particularly from processed sources like cooking oils) contribute to higher rates of death from heart disease. The healthiest diets include a balance of different fatty acids, ideally from a diverse diet of whole, unprocessed foods. Here’s an interview by the editors of the British Medical Journal with Christopher E. He briefly discusses polyunsaturated fats, the study findings, how the researchers recovered data, and the possibility of re-examining paradoxical findings from the past in light of current knowledge.
And for more from PN, Ryan Andrews has written several All About articles on fats and oils that will add to your understanding.

Eggs contain many healthy ingredients and are a unique anti-oxidant good for our eyes and weight loss. Several decades ago it was commonly accepted that consuming of fats, especially saturated fat are connected with heart diseases. Lower the intake of grains, especially wheat, because they have very little nutrient substances and easily cause some disease. The data that intake of proteins in the body stimulates the secretion of calcium in the bones for a short while is true. Highly protein food lowers blood pressure and is large opponent of diabetes that lowers the risk of kidneys failure. In the products with low fat all natural fats are replaced with substances which are exceptionally harmful.
The basic attitude is that you must eat low fat food with representation of carbohydrates of 50-60% of the total calories.
In the frequent experiments of optimal correlation of fats and carbohydrates in the nutrition, scientists always come to the conclusion that low-carb, high-fat diets have the advantage. Polyunsaturated fats are considered to be healthy because some studies show that they lower the risk of heart diseases. We get the fact that low-calorie nutrition lowers the weight, eliminates fat in the body and improves health.

After a super-tough ride, run, ski, or climb, what’s your best nutrition option for recovery?  In the world of sports nutrition, there’s a lot of buzz about low-fat chocolate milk.  Since I generally like simple, whole-food nutrition over chemicals and processed foods, the thought of it appeals to me (although many cheap chocolate syrups are made with chemicals – more on this below).  While there are hundreds of sports nutrition foods and drinks available on the shelves, is it possible that a favorite childhood drink holds the secrets to muscle recovery, stronger rides, and lean body mass retention?
Then, earlier this year, the University of Texas conducted a series of studies to test the affects of different drinks used in recovery on the performance of cyclists over a one-month period.  The drinks studied included low-fat chocolate milk, a carbohydrate solution sports drink similar to Gatorade, and a calorie-free drink similar to Vitamin Water. First, it’s no secret that these studies were partially funded by the milk industry.  What does this mean to me? Also, the studies were small in scale.  They were performed on one type of athlete, cyclists, with only 9 and 32 participants in each.
Considering the study conclusions in support of chocolate milk, I think we can take their data and do better. 1.  Organic – I recommend organic milk to avoid any hormones or antibiotics that may have been given to cows in conventional dairies.
3.  Yogurt – If you want to boost the absorption of antioxidants, choose plain organic yogurt with honey over organic milk – the healthy bacteria will promote increased antioxidant absorption and better digestion just in time for all the free radicals that abound after exercise.

Trans fat is bad for you because it raises bad cholesterol and lowers good cholesterol at the same time.
Eat more vegetables, fruits, whole grain products, lower-fat milk products, fish, lean meat and meat alternatives such as beans, lentils and tofu.


Under mandatory nutrition labelling, the Nutrition Facts label on most pre-packaged foods is presented in a standard format making it easy to read. For information on trans fat regulations for foods sold at school visit our School section.
Sugar alcohols occur naturally or may be produced by hydrogenation of monosaccharides and disaccharides. On a weight basis, 74% of this product is carbohydrate (2 grams out of 2.7 grams serving size).
We don't know the proportions of water and mono- and diglycerides, but we can make some estimates.
Unfortunately, the procedure for "expressing" the fatty acids as triglycerides is not defined. The primary ingredients remain the same, but soy lecithin and several more vitamins have been added. And almost anything we swallow can be good or bad for us, depending on whether we have a deficiency or a massive overabundance.
But there’s no “fat” aisle at the grocery store, and most nutrition labels don’t classify fats beyond telling you whether they’re saturated or unsaturated. They took raw data from the Sydney Diet Heart Study and re-evaluated it in light of recent mortality data for coronary heart disease and cardiovascular disease, hoping to learn what kind of fats are really good for the heart. Researchers didn’t ask them to change their diets in any way, although some voluntarily stopped using butter in favor of the (supposedly) healthier margarine.
Lower levels of saturated fat would, in turn, decrease cardiovascular risk factors such as total cholesterol and total triglycerides.
And after years of being told by doctors, nutritionists, and the media to eat vegetable oils high in polyunsaturated fats, they’re understandably confused and exasperated. Start with an idea (hypothesis), gather data, interpret the data, and presto-bingo, you have the answer! And the results of the original study were, quite simply, impossible to interpret, given what the scientific community knew and accepted in 1970.

Most trans fat is artificial because it is created when a liquid vegetable oil is made into a solid fat, like margarine or shortening. Studies show that people who eat more artificial trans fat are at a higher risk of heart disease than people who eat less trans fat.
Too much water causes a decrease in key electrolytes that are really important for important things like your heart pumping. But it’s possible that these findings confused them, because they went against accepted wisdom.
Mostly used grain is the wheat containing the protein called gluten; recently many people are sensitive to it. But, this way of nutrition can be bad for those with high weight, diabetes or metabolic syndrome.
Furthermore, they added more lean muscle mass and shaved off more fat than those who consumed the carbohydrate drink.
Managed to loose 7kg of weight whilst still maintaining all the strength and power output I had previously, equating to around a 10% increase in power to weight ratio in a period of 3 months.
Several studies show that greater risk of colon cancer is in those people who have 4, then those who have 2 meals during the day. Through the use of Kelli’s services, I have been able to make some key changes to the way I eat on a daily basis and I have lost several pounds as a result.
