5 Surprising Sources of Food Poisoning

1.  Fresh Raw Produce  
  • Animal waste can contaminate produce in the field                              
  • Wash foods well before cut for salad; wash foods like melons before cutting in to them
2.  Your Counter Top and Sponge
  • Clean counter tops with antibacterial spray  
  • Replace sponges, wash cloths and kitchen towels often; allow dishes to air dry
  • Use color coded cutting boards: at least one for meats and one for fresh veggies and fruits; do not stack cutting boards in storage
3.  Barbecues  
  • Cold foods (e.g. potato salads, macaroni salad, etc.) left out should not be eaten after 1 hour
  • Remember to use different plates and utensils for raw and cooked foods
4.  Leftovers
  • Store right away in shallow pans- it's safest to put extra food away before the meal starts!
  • Heat leftovers to 165 F for 15 seconds
5.  Your Hands and the Hands of Others
  • Germs often spread in food handling!
  • Wash hands
    • Every time before handling food
    • In between handling raw and cooked foods
    • After touching any part of face, hair, etc.

Five Breakfast Ideas with 30g of Protein Ready in 5 minutes or Less!

New research indicates that a breakfast containing at least 30g of protein may ward off hunger and help with weight loss.  Unfortunately, many people struggle to fit this much protein into breakfast.  Below are five super quick & easy 30g protein breakfast ideas to start your day!

2 cups Kashi Golean cereal with 1 cup high-protein milk (e.g. Fairlife or HEB’s Mootopia):
~400 kcal, 32g protein, 72g carbs (21g fiber) 
3 eggs, 2oz Cabot 50% light cheddar cheese (cut into pieces), whisk all together and scramble in non-stick pan with one 6” whole wheat tortilla:  
~500 kcal, 40g protein, 27g carbs (4g fiber)

1 cup 2% cottage cheese (or two cups plain2% greek yogurt), 1 cup chopped fruit (e.g. pineapple, berries, or peach slices):
~300 kcal, 32g protein, 30g carbs (2g fiber)

And for those who want to put NO effort into breakfast:

At McDonalds: Steak, Egg and Cheese McMuffin with 1% milk jug:
~530 kcal, 34g protein, 42g carbs (2g fiber)

At Subway: Ham, Egg White & Cheese Omelet Sandwich on Flatbread (6") with 1oz extra cheese with water
           ~480 kcal, 30g protein, 44g carbs (2g fiber)

Trans Fat "Ban" Overdue

Removing partially hydrogenated oil from the food supply is a major win for America!  However, claiming that the ban is on "trans fats" is technically incorrect.  Small amounts of natural trans fats are found in dairy and these will not be banned.  The "ban" is on partially hydrogenated fats, which are lab produced fat chemical seriously contributing to heart disease risk.  The Federal Food and Drugs Act of 1906 determines a food is adulterated if it "contain any added poisonous or other added deleterious ingredient which may render such article injurious to health."  For decades, science has indicated that added trans fats are not safe, so now the FDA will finally STOP designating this man-made substance as a safe additive for the US food supply.  It's about time!

Harvard School of Public Health article explaining the history/health risks of artificial trans fats

And don't worry, the food manufacturers will reformulate refrigerator cookie dough and microwave popcorn with another unhealthy solid fat, so junk food will remain readily available...

Limiting Fructose Helps At-Risk Kids Cut Liver Fat

When scientists replaced sugars with complex carbohydrates and fruits in obese kids' diets, they saw dramatic drops in liver fat in only 10 days, even though the kids did not lose any weight. High amounts
of liver fat increase risk for conditions like Type 2 diabetes and heart disease.
Because of the chemical structure of fructose, it is much more likely to be turned into fat in the liver--BOTH regular cane sugar and high fructose corn syrup contain approximately 50% fructose. There is no convincing evidence that either type of sugar is better or worse than the other for health. There is evidence that replacing these sugars with starchy foods, especially whole grains, does improve health and reduce liver fat.
In a study we conducted at GW a few years back, nearly 40% of DC high school students surveyed indicated they would choose to drink soda, rather than water (n=405; unpublished).

Cholesterol Exonerated!

A single cholesterol molecule
According to the Washington Post, Americans' greatest frenemy dietary component may no longer be included on the 'to be avoided' list in the 2015 Dietary Guidelines, the nutrition document guiding America's food and nutrition policies and programs.
'Blood cholesterol' is a misnomer--'cholesterol' in your blood are particles that contain cholesterol*, but also fats, proteins, and other molecules. 'Blood cholesterol' particles are made mostly in the liver and do not come directly from the diet. If your liver is a factory producing proteins and lipids (fat, cholesterol, etc.), 'blood cholesterol(s)' are like boxes shipping these food molecules to other parts of your body. Your liver is likely to make a lot of 'blood cholesterol' particles after eating too much sugar, white starches, artificial trans fats, and excessive Calories from any source.
Your 'total cholesterol' number is the sum of VLDL, LDL, and HDL plus some less common particles:
VLDL (Very Low Density Lipoprotein)- Extra Calories from any kind of food are often turned into fat in the liver. The VLDL packs up these little pieces of fat and moves them into to fat cells elsewhere, often your butt and hips ladies. This sounds bad, but it's really good. In extreme cases, storing fat in the liver leads to cirrhosis and liver failure. Yikes!
LDL (Low Density Lipoprotein)- After the VLDL gives fat to your butt, it gets more dense and turns into a LDL. LDL is called the 'bad' cholesterol. The video above is a graphic of an LDL, where cholesterol molecules are in the center.  But LDL is only bad when there's too much of it**, promoting blocked arteries over time. Otherwise, LDL is kind-of useful. The actual cholesterol molecule in LDL can be dropped off to the gonads to make testosterone or estrogen, and who doesn't love sex hormones?
HDL (High Density Lipoprotein)- HDL picks up excess cholesterol and fat throughout the body and higher amounts are associated with less clogged arteries and heart disease. So some call it 'good cholesterol'
(1) Americans eat too much of their top 10 food choices, mostly crap: (ordered most to least consumed according to the 2010 Dietary Guidelines): 1) starchy dessert; 2) yeast breads; 3) chicken dishes; 4) soda; 5) alcohol; 6) pizza; 7) tacos; 8) pasta; 9) beef dishes; and 10) dairy desserts ---->; THEN
(2) After digestion, the liver receives these foods as simple sugars, fats and amino acids. The liver can and will turn excessive Calories from any source into fat. The liver packs these fats into VLDL. VLDL is released into the blood and gives fat to your butt, love handles, etc. ----> THEN
(3) The VLDL gets more dense and is changed to an LDL ---> THEN
(4) Eating too much over the years (especially white starch and trans fats), promotes chronic inflammation, too much LDL in the blood, and build up of plaque in the arteries ---> THEN
(5) 1 in 4 Americans dies of heart disease, often way too early

The take home message is simple, be active, don't eat more food than you need, and don't eat a typical American diet of cookies, white bread, fried chicken, soda, beer, pizza, tacos, pasta, hamburgers, and ice cream.
I am the food police, but it's out of love.
* The cholesterol added to blood cholesterol' particles is mostly made in the liver, and less from the diet.
**LDL in the blood is affected by diet, but also heavily influenced by genetics. An extreme case is familial hypercholesterolemia. LDL are moved out of the blood and into the liver by special proteins. When the genetic code for these proteins is messed up, the LDL can't be removed from the blood. People with this condition have super high blood LDL.
