Calorie-free fats

Although fat substitutes may reduce the caloric contents of the foods in which they are used, caution is still necessary. Foods labeled fat free are not calorie free. If an individual feels that he or she can eat more of a food containing a fat substitute, his or her total caloric intake may actually increase. see also Detergents Lipids Soap. 

Function Calorie-free substitute for fats and oils. 

The fat-labeling claims do not provide any indication of the caloric content of the food product. However, products containing one-third to one-half fewer calories of the reference food may be labeled as light. If more than 50% of calories in a food are derived from fat, the fat content of the reduced-fat version must be reduced by 50% or more. The term calorie free and low calorie only can be used on products with less than 5 calories per serving and less than 40 calories per serving, respectively, and reduced or fewer calories only can be used on products that have less than 25% of the calories in the regular product (12). 

Gamble Co. (Cincinnati, Ohio), petitioned the FDA in 1987 for use of olestra as a calorie-free replacement for fats and oils. The petition included results of more than 150 safety studies, several chronic feeding studies, and clinical studies. According to the FDA, these studies included (44) ... 

As regards fat labeling, the nutrition panel must include total fat, calories from fat, saturated fat, and cholesterol. Declaration of polyunsaturated or monounsatu-rated fat content are mandatory only if the other is declared or if a claim about fatty acids or cholesterol is made, unless the product meets the criteria for a fat-free claim. All fat amounts are expressed to the nearest 0.5-g increment below 5 g, to the nearest gram above 5 g, and as zero if a serving contains less than 0.5 g. Saturated fat includes all fatty acids that do not contain a double bond. Polyunsaturated fat includes only cis, cri-methylene-interrupted fatty acids, and monounsaturated fat is defined as cis-monounsaturated fatty acids. Saturated, polyunsaturated, or monounsaturated fat is declared as weight of the fatty acids, while fat is expressed as the weight of triglyceride based on the total amount of lipid fatty acids. 

The body synthesizes all of our manly androgens including testosterone from fat. In fact several studies have documented that diets containing less than 10% fat can significantly decrease a male s androgen production and increase estrogen synthesis. In most cases a diet that provides a minimum of 20% of its calories from fat will also augment a male s total and free testosterone production. 

Cooking spray lets you apply a thinner layer of oil them you could probably achieve by pouring normal liquid vegetable oil out of a bottle. The FDA states that any food substance with less than five calories and less than 0.5 g of fat per serving can be labeled calorie-free and fat-free, respectively. So manufacturers of cooking spray adjust the recommended serving size to contain less than those limits. As a result, your can of spray contains hundreds of servings—go check your pantry if you don t believe it ...

Nowadays, food scientists are including in their research and product development equations the production of snacks with minimal fat calories and fat decomposition products to counter contents known to have adverse effects on human health. At the same time they seek to produce snacks with similar sensory properties (flavor, texture, and overall acceptability) compared to the norm. A healthful balance of fatty acids (saturated monounsaturated polyunsaturated and omega 6 omega 3) and the production of snacks free of trans fatty acids are taken into consideration. 

In the United States, additional ramifications maybe expected from FDA s announcement of final regulations for new food labeling requirements under the directive of the Nutrition Labeling and Education Act of 1990 (2). Among other things, these regulations limit health claims that can be made on food labels. They also require new information on nutrient content, and limit the use of descriptors such as low and free in association with calories, fat levels, and other food product characteristics. 

Essential fatty acid deficiency is rare but can occur with prolonged lipid-free parenteral nutrition, very low fat enteral formulas, severe fat malabsorption, or severe malnutrition. The body can synthesize all fatty acids except for linoleic and linolenic acid, which should constitute approximately 2% to 4% of total calorie intake. 

Although these experiments showed growth was possible using casein hydrolysate, Rose also demonstrated that when the amino acid mixture was used rather than the intact protein, additional calories had to be provided as fat plus carbohydrate, if nitrogen balance was to be maintained. It was later shown that the carbohydrate was needed to protect the free amino acids from oxidation in the intestinal epithelium in the course of absorption. Further, amino acids are poorly tolerated by mouth, causing vomiting and/or diarrhea. After World War II attempts to feed very emaciated prisoners in concentration camps with protein hydrolysates were unsuccessful. It was then recognized that osmotic effects from the amino acids were responsible for the unpleasant consequences. 

The flour made from Jerusalem artichoke tubers is a low-calorie, fat-free source of energy and fiber, which is rich in nutrients, including calcium, potassium, and iron. For the health food market, Jerusalem artichoke flour is often included in products that also contain live bacteria, especially bifidobacteria. The bacteria (probiotic) and food substrate (prebiotic) act to maintain a healthy balance of microflora in the colon (see below). 

Q3 The thyroid hormones thyroxine and triiodothyronine have many metabolic effects. In adults they increase metabolic rate, oxygen and calorie consumption, stimulate carbohydrate metabolism and turnover of protein, deplete fat stores and increase catabolism of free fatty acids. Thyroid hormones stimulate heart rate and force and increase pulmonary ventilation, gastrointestinal motility and central nervous system (CNS) activity. Actions on the heart can result in an increased incidence of dysrhythmias. Thyroid hormones are critical for the normal growth and development of the infant, particularly in respect of skeletal growth and maturation of the CNS. 

Yet there are definitely ways you can, at the very least, limit the amount of weight you will gain. Follow a healthy diet that s low in fat, nutrient-poor carbohydrates, and calories. When choosing snacks and nibbles to replace cigarettes throughout the day, opt for those lowest in calories, such as pretzels, popcorn, sugar-free hard candies, carrot sticks, celery stalks, and the like. And be certain to engage in some physical activity each and every day. 

A calorie intake of 1,800-2,500 kcal/day (ca. 30 kcal/ kg BW/day) is guaranteed by the adequate administration of fats (70-140 g) and carbohydrates (280-325 g). Consideration should be given to the fact that cirrhotic patients show a resistance to insulin and a glucose intolerance, with a tendency to develop a diabetic metabolic condition. For this reason, it might well be necessary to administer insulin. Carbohydrates reduce the plasma levels of ammonia and free tryptophan. 

Lactose-free, liquid for replacement feedings (Ensure, Isocal, and Osmolite), consisting of 50% carbohydrates, 15% protein, 15% fat, and 20% other nutrients in an isotonic solution (300-340 mOsm/kg H20). Provides 1 calorie per milliliter of feeding. 

Another area that attracts the consumer s attention is weight control, it is estimated that 34 million people in the U.S. weigh 20% in excess of what is ideal (13). It is not surprising, therefore, to see a rising tide of diet beverages, sugar-free snacks, desserts, cereals, low calorie frozen foods, low-fat processed meats, and a host of calorie-controlled prepared meals. This trend is expected to continue — a challenge and an opportunity for the food industry.
