In six countries, plant-based diets or pescatarian diets were associated with lower odds of moderate-to-severe COVID-19. These dietary patterns may be considered for protection against severe COVID-19 In 2884 front-line healthcare workers from six countries (France, Germany, Italy, Spain, UK, USA), individuals who reported following plant-based diets and plant-based diets or pescatarian diets that were higher in vegetables, legumes and nuts, and lower in poultry and red and processed meats, had 73% and 59% lower odds of moderate-to-severe COVID-19, respectively.

The traditional Mediterranean dietary pattern includes mainly whole, minimally processed plant foods including cereal grains, legumes, vegetables, fruit, nuts, and fish with small amounts of meat, milk, and dairy products and a regular modest amount of alcohol.4 The DASH diet emphasizes fruit, vegetables, and low-fat dairy products and includes whole grains, poultry, fish, and nuts, and is reduced in fats, red meat, sweets, and sugar-containing beverages.4 Combining the two diets, the MIND diet emphasizes natural, plant-based foods, specifically promoting an increase in the consumption of berries and green leafy vegetables, with limited intakes of animal-based and high saturated fat foods.
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.
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.

By many measures, the population of the United States is the unhealthiest of any high-income country despite spending much more money, as a share of the economy, on health care. The incidence of chronic disease is higher and life expectancy is lower.
Many chronic conditions plaguing Americans, such as obesity, diabetes, and high blood pressure, are avoidable with a prudent diet and lifestyle. Today, more than 42% of American adults have obesity, as do 19.3% of children of age 19 and under. The U.S. has the world’s 12th-highest obesity rate, after Kuwait. (The top 10 are all small Pacific island nations.)
Diet makes a difference. Nearly half of all deaths in the U.S. from heart disease, stroke, and type 2 diabetes are associated with diet, such as the over-consumption of processed meats and sugar-sweetened beverages and insufficient intake of fruits, vegetables, and whole grains.
Conclusion All NAFLD histological stages were associated with significantly increased overall mortality, and this risk increased progressively with worsening NAFLD histology. Most of this excess mortality was from extrahepatic cancer and cirrhosis, while in contrast, the contributions of cardiovascular disease and HCC were modest.
Published in the British Journal of Nutrition the research has found higher consumption of cruciferous vegetables, such as broccoli, Brussels sprouts and cabbage, is associated with less extensive blood vessel disease in older women.
Using data from a cohort of 684 older Western Australian women recruited in 1998, researchers from ECU’s School of Medical and Health Sciences and The University of Western Australia found those with a diet comprising more cruciferous vegetables had a lower chance of having extensive build-up of calcium on their aorta, a key marker for structural blood vessel disease.
Dr Blekkenhorst said women in this study who consumed more than 45g of cruciferous vegetables every day (e.g. ¼ cup of steamed broccoli or ½ cup of raw cabbage) were 46 percent less likely to have extensive build-up of calcium on their aorta in comparison to those consuming little to no cruciferous vegetables every day.
Research professor of medicine Martha Shrubsole, Ph.D., and colleagues at Vanderbilt University Medical Center have published the first study to evaluate intakes of meat, cooking methods and meat mutagens and risk of developing sessile serrated polyps (SSPs, also called sessile serrated lesions). Shrubsole previously reported that consuming high levels of red meat increased the risk of developing all types of polyps, but that the likelihood of developing SSPs was two times greater than the risk of developing adenomas and hyperplastic polyps (HP).
Conventional colorectal adenomas are the precursor lesions for most colorectal cancers. SSPs, however, represent an alternative pathway to carcinogenesis that may account for up to 35 percent of colorectal cancers. Because a diagnostic consensus for SSPs was not reached until 2010, few epidemiologic studies have evaluated risk factors.
In conclusion, these two outstanding studies support the fact that (1) it is not the quantity of calories per se that matters but the quality of the diet and (2) even in subjects of advanced age, adherence to a MedDiet is rapidly associated with different metabolic effects and reduced disease risk factors.
The media is extremely loud on this subject and the percentage of vegetarians in the United States is approximately 5% or less.
Fast food is still fast food, meat or no meat.
My post is not an endorsement.
I haven’t eaten at a Taco Hell in years. And the availability of 50 meat free items is not going to entice me to start eating there again. If you’re eating less meat for health reasons that’s fine. But don’t pursue your meat-free lifestyle with fast food.
