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 continuedFruits 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 continuedMeats, 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

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 NUTRACEUTICALSCONTINUED

Various enzyme supplements

14

Proteins in functional foods

Hen egg protein- specific proteins- mineral binding-specifically calcium-prevent insoluble Ca Phosphatecomplexes-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
