Holcomb et al. (1991) reported that both L. acidophilus and
Bifidobacterium were able to survive and grow in soft-serve frozen yogurt after freezing [Holcomb, J.E., Frank, J.F. and McGregor, J.U. (1991), Viability of Lactobacillus acidophilus and Bifidobacterium bifidum in soft-serve frozen yogurt. Cult. Dairy Prod. J. 26, 4-5.]

pre-frozen yogurt can contain active cultures — just have to check the label.

How to tell if Yogurt is bad, rotten or spoiled?


Although not a perfect test, your senses are usually the most reliable instruments to tell if your yogurt has gone bad. A small amount of liquid is ok in most yogurts, it is called whey and actually contains several nutrients that should be mixed into the yogurt before eating. But an increased amount of surface liquid (or, in the case of Yoplait yogurt and a few others that do not have any excess liquid to begin with, it’s when a puddle begins to form) and a curdling texture near the bottom of the container are the first signs of yogurt going bad. The final signal that your yogurt has indeed gone bad is the formation of mold and at that point you must throw the entire container away, no matter what. Live bacterial cultures in yogurt act as a preservative, but once those cultures start to die off then mold can start to form. Never consume mold in any shape or form!”

Are You a Carboholic? Why Cutting Carbs Is So Tough – The New York Times

July 25, 2017

QT:{{”
The conventional thinking, held by the large proportion of the many researchers and clinicians I’ve interviewed over the years, is that obesity is caused by caloric excess. They refer to it as an “energy balance” disorder, and so the treatment is to consume less energy (fewer calories) and expend more. When we fail to maintain this prescription, the implication is that we simply lack will power or self-discipline.

“It’s viewed as a psychological issue or even a question of
character,” says Dr. David Ludwig, who studies and treats obesity at Harvard Medical School.

The minority position in this field — one that Dr. Ludwig holds, as do I after years of reporting — is that obesity is actually a hormonal regulatory disorder, and the hormone that dominates this process is insulin. It directly links what we eat to the accumulation of excess fat and that, in turn, is tied to the foods we crave and the hunger we experience. It’s been known since the 1960s that insulin signals fat cells to accumulate fat, while telling the other cells in our body to burn carbohydrates for fuel. By this thinking these carbohydrates are uniquely fattening.

Glycemic Index and Glycemic Load Chart

Q: What is glycemic load in very simple terms?
Susan Weiner: Glycemic load is a ranking system for carbohydrate-rich food that measures the amount of carbohydrates in a serving of food.
Foods with a glycemic load (GL) under 10 are considered low-GL foods and have little impact on your blood sugar; between 10 and 20 moderate-GL foods with moderate impact on blood sugar, and above 20 high-GL foods that tend to cause blood sugar spikes.
Q: How is glycemic load related to glycemic index?
SW: The glycemic index indicates how rapidly a carbohydrate is digested and released as glucose (sugar) into the blood stream. In other words, how quickly foods break down into sugar in your bloodstream. A food with a high GI raises blood sugar more than a food with a medium to low GI.
But the glycemic index does not take into account the amount of carbohydrate in a food. So glycemic load is a better indicator of how a carbohydrate food will affect blood sugar.

Diabetic Diet – Great Veggies – Meals – Diabetes

June 5, 2017

Gr8 Low-carb #Veggies http://www.HealthCentral.com/diabetes/c/17/20167/good-veggies Top: collards, spinach, #kale, chard, red peppers; Bottom: cukes, eggplant, mushrooms, alfalfa

QT:{{"

“In fact, the healthiest of all vegetables, according to "Nutrition Action Health Letter," is one that I had never prepared before: collard greens, with a score of 461.

The number 2 vegetable, spinach, with a score of 424, is one that I eat both raw and cooked. Like collards, and number 3 kale (score 410) and number 4 Swiss chard (322) all of these green leafy vegetables pair extraordinarily well with ham or bacon or other smoked meat and vinegar (a tip I picked up from Ruth Reichl’s Gourmet Cookbook).
Then comes red pepper (score 309), which I usually add to my salad but is also great cooked. Skipping a couple of high-carb veggies, the list then goes to broccoli at 179.
Next in order are okra, 165; Brussels sprouts, 143; lettuce, 141; and asparagus, 84. I was surprised that tomatoes and avocados, two honorary vegetables (technically fruit), ranked at 76 and 71 respectively. Wonderful cauliflower ranked even lower at 64, cabbage at 44. Near the bottom of the list are cucumber, eggplant, mushrooms, and alfalfa sprouts.

My attention went in that direction anyway after reading Michael Pollan’s He notes there that when we largely switched from eating leaves to seeds (as in grain), the problems with the so-called "Western Diet" began. It is indeed striking how many of the top veggies are leaves.”

Baths Versus Exercise, a Study in Calories – The Atlantic

Baths vs #Exercise, a Study in Calories
https://www.theAtlantic.com/health/archive/2017/04/baths-and-calories/522756 In 1hr, burn 60 in a hot bath vs ~550 on a bike ride. Laziness has benefits!

QT:{{”
The researchers set out to see how exposure to heat can alter the molecules in our bodies. There were only 14 people (all men) in the study. They took hour-long baths at 104-degrees Fahrenheit and did burn calories, which were also measured, since energy is required to keep our cores around 98.6-degrees. But the men only burned an average of about 61 calories more than if they had been sitting at room temperature. When they exercised on a bike for the same amount of time, they burned between 515 and 597 calories.
