The calories that children and adolescents consumed from ultraprocessed foods jumped from 61% to 67% of total caloric intake from 1999 to 2018, according to a new study from researchers at the Friedman School of Nutrition Science & Policy at Tufts University. Published August 10, 2021, in JAMA, the study analyzed dietary intake from 33,795 children and adolescents nationwide.
The largest spike in calories came from such ready-to-eat or ready-to-heat dishes as takeout and frozen pizza and burgers: from 2.2% to 11.2% of calories. The second largest spike in calories came from packaged sweet snacks and desserts, the consumption of which grew from 10.6% to 12.9%.
Frozen pizza and burgers? Is this a problem?
Findings In this serial cross-sectional study of nationally representative data from 33 795 US youths aged 2-19 years, the estimated percentage of total energy consumed from ultraprocessed foods increased from 61.4% to 67.0%, whereas the percentage of total energy consumed from unprocessed or minimally processed foods decreased from 28.8% to 23.5%.
Older people with prediabetes who followed a diet rich in sardines for 1 year show significant reductions in risk of developing type 2 diabetes compared with those placed on a similarly healthy diet but without the sardines, results from a new randomized trial show.
“A 1-year, sardine-enriched type 2 diabetes-preventive diet in an elderly population with prediabetes exerts a greater protective effect against developing type 2 diabetes and cardiovascular events, by improving anthropometric parameters, blood chemistry profile, lipid composition in erythrocytes membranes, and metabolomics data,” report the authors in research published in Clinical Nutrition by Diana Díaz-Rizzolo, PhD, of the Hospital Clinic of Barcelona, Spain, and colleagues.
When the researchers looked at the functions of the genes in the three sample types, they found that the ancient and non-industrial groups contained a diverse array of genes linked with the breakdown of starches. This indicates that the diets of the ancient and non-industrialised populations were high in complex carbohydrates, like vegetables and grains.
Researchers examined data from over 50,000 people residing in Denmark taking part in the Danish Diet, Cancer, and Health Study over a 23-year period. They found that people who consumed the most nitrate-rich vegetables had about a 2.5 mmHg lower systolic blood pressure and between 12 to 26 percent lower risk of heart disease.
Lead researcher Dr Catherine Bondonno from ECU’s Institute for Nutrition Research said identifying diets to prevent heart disease was a priority.
“Our results have shown that by simply eating one cup of raw (or half a cup of cooked) nitrate-rich vegetables each day, people may be able to significantly reduce their risk of cardiovascular disease,” Dr Bondonno said.
In Mexico obesity reached epidemic proportions after it joined NAFTA with the United States and Canada in the early 1990s, making processed food more easily available. Diets quickly changed as many people, particularly those on lower incomes, replaced largely healthy traditional staples (corn tortilla, frijoles, Jamaica Water) with highly processed alternatives (hotdogs, nuggets, sodas). Sugar consumption soared and waistlines exploded. In the past 20 years the number of obese and overweight people has tripled, with 75% of the population now overweight.
Mexico also has the sixth highest mortality rate from Covid-19, which has spurred the government to escalate its war against obesity.
In a review published this week in mBio, microbiologist Heenam Stanley Kim, Ph.D, from Korea University’s Laboratory for Human-Microbial Interactions, in Seoul, examined emerging evidence suggesting that poor gut health adversely affects COVID-19 prognosis. Based on his analysis, Kim proposed that gut dysfunction — and its associated leaky gut — may exacerbate the severity of infection by enabling the virus to access the surface of the digestive tract and internal organs. These organs are vulnerable to infection because they have widespread ACE2 — a protein target of SARS-CoV-2 — on the surface.”There seems to be a clear connection between the altered gut microbiome and severe COVID-19,” Kim said.
High consumption of UPF in this Mediterranean cohort was associated with a 58% increased risk for CVD mortality and 52% higher risk of dying from ischemic heart disease (IHD) and cerebrovascular causes, independently of known risk factors for CVD, even among individuals who otherwise adhered to the Mediterranean diet.
The foods that contributed most to total UPF consumed were processed meat, which accounted for 19.8% of UPF intake; pizza (16.8%); and cakes and pies (13.4%).
The researchers found a direct linear dose-response relation between a 5% increase in the proportion of UPF in the diet and risk for all-cause and CVD mortality.
After reading the full summary of the study I had some issues with the study findings on pizza. Apparently I’m not alone. From the comment section:
Pizzas were mentioned by the authors and Dr. Walter Willet (for whom I have always had great admiration and consider him among my 3 most valued nutrition resources) as a UPF. However, even as a consistent follower of Mediterranean diet for >40 years, I see nothing wrong with occasional enjoyment of two or three slices of Margherita pizza (which is not covered with any processed meats or extra cheeses).
Participants also answered questions about their food and alcohol consumption at baseline and through two follow-up assessments. The Food Frequency Questionnaire asked participants about their intake of fresh fruit, dried fruit, raw vegetables and salad, cooked vegetables, oily fish, lean fish, processed meat, poultry, beef, lamb, pork, cheese, bread, cereal, tea and coffee, beer and cider, red wine, white wine and Champaign and liquor.
Here are four of the most significant findings from the study:
Cheese, by far, was shown to be the most protective food against age-related cognitive problems, even late into life;
The daily consumption of alcohol, particularly red wine, was related to improvements in cognitive function;
Weekly consumption of lamb, but not other red meats, was shown to improve long-term cognitive prowess; and
Excessive consumption of salt is bad, but only individuals already at risk for Alzheimer’s Disease may need to watch their intake to avoid cognitive problems over time.

Chemical compounds in foods or beverages like green tea, muscadine grapes and dark chocolate can bind to and block the function of a particular enzyme, or protease, in the SARS-CoV-2 virus, according to a new study by plant biologists at North Carolina State University.

I don’t think this is a game changer but it is interesting nonetheless.
If you’ve been anywhere near the internet I’m sure the headlines caught your eye. But a 43% higher risk of fractures just seemed really high to me with a meat free diet as the cause. I found the following article online. Since most people nowadays can’t get past the headlines you’ll find the second paragraph completely ignored by the media.
Compared with people who ate meat, vegans with lower calcium and protein intakes on average, had a 43% higher risk of fractures anywhere in the body (total fractures), as well as higher risks of site-specific fractures of the hips, legs and vertebrae, according to a study published in the open access journal BMC Medicine. Vegetarians and people who ate fish but not meat had a higher risk of hip fractures, compared to people who ate meat. However, the risk of fractures was partly reduced once body mass index (BMI), dietary calcium and dietary protein intake were taken into account.
The authors caution that they were unable to differentiate between fractures that were caused by poorer bone health (such as fractures due to a fall from standing height or less) and those that were caused by accidents because data on the causes of the fractures were not available. No data were available on differences in calcium supplement use between the different diet groups, and as in all dietary studies the estimates of nutrients such as dietary calcium or dietary protein are subject to measurement error. As the study predominantly included white European participants, generalisability to other populations or ethnicities may be limited, which could be important considering previously observed differences in bone mineral density and fracture risks by ethnicity, according to the authors.
As I was gathering my thoughts the algorithms started doing what they do and this popped up in YouTube.
Let’s discuss the latest paper from the EPIC database. Excuse me eating while working. Not enough hours in day. Short version: this is a database from 90’s. Average fiber intake is 20 gm so not healthiest plant based eaters. Meat eaters got more vitamin D. Also (forgot to mention in video) used hormone replacement therapy up to 50% more. Both associated with stronger bones. Other studies have shown that plant based eaters have great bone health BUT you have to be healthy. Get dark greens. Drink or eat soy (studies show as good dairy for bones). Exercise and use resistance training. And take supplements if needed. I like multivitamins that have K2 as that may be a nutrient vegans are deficient in unless you eat natto 🤮. Definitely vitamin D if deficient. The EPIC Oxford cohort are not the healthiest vegans and vegetarians BUT have less ischemic stroke, weight less, generally better heart and less of certain cancers despite poor supplementation and diet habits.

I love it when someone else does the work for me. If you have eleven minutes listen to Dr. Davis’ analysis. I am now less confused.
