Presentation Transcript

  1. Lecture 6B-21 OCT. 2013 PROTEINS

  2. Proteins in foods Complete-meats, fish, poultry -eggs, milk, cheese -SOYBEANS -QUINOA- BUT CAUTION Incomplete-corn, peanuts, peas -navybeans -grains, nuts, sunflower and sesame seeds

  3. PROTEINS IN FOODS CONTINUED Complementary proteins -corn and beans -rice and beans -bread and peanut butter -macaroni and cheese

  4. Proteins in foods continued Breads, grains, cereals Bread –2 slices -2 grams protein 1 roll-2 grams protein Rice-1/2 cup cooked- 2 grams protein

  5. Proteins in foods continued Fruits and vegetables canned pears-1/2 cup- 1 gram protein 1 apple- medium-400 mg protein carrot sticks- 1 carrot- 1 gram protein asparagus – ½ cup- 2.8 grams protein soybeans-1/2 cup cooked-11 grams protein

  6. Proteins in foods continued Milk and dairy products Fat free milk- ½ cup- 4 grams protein Ice cream-2/3 cup-3 grams protein Cheese-84 grams- 24 grams protein

  7. Proteins in foods continued Meats, poultry, fish and nuts Chicken breast – 84 grams- 26 grams protein Roast pork-84 grams-22.5 grams protein Roast beef –84 grams-22 grams protein Fish- 84 grams-16-20 grams proteins Nuts-84 grams-15 grams most nuts -chestnuts are 1.8 grams protein

  8. FADS IN PROTEIN DIETS DR. ATKINS DIET -the same high protein, high fat, high cholesterol diet reincarnate

  9. ATKINS DIET CONTINUED In the '60's it was the Atkins diet, in the 70's it became the Stillman Diet and in the'80's it became the Scarsdale Diet and the Protein Power Plan in the '90's.

  10. Proteins in nutraceuticals Whey- tripeptides may be blood pressure regulators via enzyme inhibition-proposal

  11. Proteins in nutraceuticals Soy- lowers total and LDL cholesterol -no effect on triglycerides and HDL cholesterol in adults but get triglycerides down in some children -all of this is controversial

  12. PROTEINS IN NUTRACEUTICALS CONTINUED SOY CONTINUED -Prostate cancer -Bone density increases -Allergy issue

  13. PROTEINS IN NUTRACEUTICALS CONTINUED Various enzyme supplements

  14. Proteins in functional foods Hen egg protein- specific proteins- mineral binding-specifically calcium -prevent insoluble Ca Phosphate complexes-proposal

  15. Issues with proteins in nutraceuticals/functional foods Isolation of effects- is the food component identified really functional? Nutraceuticals/functional food proteins-DOSE/PURITY Purity problem - Phytates and minerals issue eg. iron
