More Cheese Please

Relative risks (RR) for colorectal cancer were calculated for intakes of all 97 dietary factors, with significant associations found for 17 of them. Calcium intake showed the strongest protective effect, with each additional 300 mg per day – equivalent to a large glass of milk – associated with a 17% reduced RR. Six dairy-related factors associated with calcium – dairy milk, yogurt, riboflavin, magnesium, phosphorus, and potassium intakes – also demonstrated inverse associations with colorectal cancer risk.

The Best Replacements for Meat and Milk (no, it’s not plant milks, veggie burgers or tofu)

Beans and peas are the best meat and milk replacement from nutritional, health, environmental, and cost perspectives.

Our findings suggest that suitable alternatives to meat and milk exist and are available and affordable without necessarily requiring new technologies or product development. This contrasts with discussions in high-income countries on the needs to develop novel replacement foods, especially those that would completely mimic meat and dairy (18). Our nutritional, health, environmental, and cost analyses suggest that if one is prepared to consider foods for their properties instead of whether they are completely mimicking meat or dairy—and surveys suggest that consumers are (49)—then unprocessed legumes are, for the most part, superior to processed alternatives. This is also relevant for low and middle-income countries where legumes are readily available, but discussions on processed meat and milk alternatives are at an earlier stage, despite diets rapidly becoming similarly imbalanced as in high-income countries (1, 50).

Prioritize Protein, Polyphenols, Healthy Fats, Calcium and Vitamin D

Research suggests that those who consume more protein tend to live longer and stay stronger and healthier later in life than those who consume less. But where you get your protein matters. Plant-based sources like legumes, nuts and whole grains seem to be especially beneficial, whereas protein from red and processed meat has been linked with shorter lives, Dr. Lars Fadnes, a professor of global public health at the University of Bergen in Norway, wrote in an email. How to Eat for a Long and Healthy Life – https://www.nytimes.com/2024/09/02/well/eat/foods-longevity-aging.html

Nice article. The last time I checked the link the NYT article was freely available and not sitting behind their paywall.

One key point was not covered in the article. Pizza! Tomato sauce for polyphenols and cheese for healthy fats and calcium. You already know what not to put on your pie to improve the health benefits.

Blueberries Make You Smarter?

Half a cup of blueberries a day improved the average participant’s language skills, improved their short-term memory, and enhanced their decision-making, planning, and organizational skills. Scientists Just Discovered That Eating Blueberries Will Make You Smarter and ‘Significantly’ Improve Your Memory — https://www.inc.com/jeff-haden/scientists-just-discovered-that-eating-blueberries-will-make-you-smarter-significantly-improve-your-memory.html

So I suppose not eating blueberries for most of my life was the main driver behind my impaired language skills, memory and decision making.

I wonder if the effects are dose dependent?

Sorry Hon, I ate all the blueberries. Again.

Seed Oils – Updated 08.24.24

If you consume social media, you may have heard: Seed oils are terrible for your health–even toxic! Cooking oils derived from seeds cause everything from heart disease to inflammation to fatigue to bad skin–according to a certain subset of Internet influencers. Yet contrary to the posts demonizing the common ingredients, a bevy of scientific research disagrees…

And broadly, the best path to a healthy diet is probably what you’d expect. A diet rich in fruits and vegetables, with whole grains and lots of fiber, is best, say Calder and Johnson. “It’s what your mother told you,” Johnson adds. Moving more and eating slightly less overall, are probably also good ideas for most Americans, notes Harris. “It’s not sexy, but that’s the way it is.” What science actually says about seed oils — https://www.popsci.com/health/are-seed-oils-bad-for-you/

Update

The American Heart Association supports the inclusion of omega-6 fatty acids as part of a healthy diet. There’s no reason to avoid seed oils and plenty of reasons to eat them — https://www.heart.org/en/news/2024/08/20/theres-no-reason-to-avoid-seed-oils-and-plenty-of-reasons-to-eat-them

You’re welcome.

Beans for Breakfast – 06.11.24

Lead author Yanni Papanikolaou and colleagues analyzed data from the National Health and Nutrition Examination Survey’s What We Eat in America program to study how often U.S.-based adults consume beans. In their analyses, they focused on how often Americans consumed white and red kidney beans, black beans, chickpeas, and pinto beans. The researchers observed that adults who routinely consumed these beans had improved ratios of polyunsaturated fatty acids, monounsaturated fatty acids, and saturated fatty acids compared to those who did not consume beans. Those who ate beans also consumed 30% more fruits and 20% more vegetables. Higher Intake Of Beans Linked To More Nutritious Diet — https://www.forbes.com/sites/anuradhavaranasi/2024/06/11/higher-intake-of-beans-linked-to-more-nutritious-diet/

Remember Research Reveals One Simple Habit That Promotes Longevity AND Provides Extra Income in Retirement.

I’ve expanded my collection of cookbooks in search of more bean recipes.

It’s bean a lot of fun.

Eat The Real Paleo Diet…(eat more plants)

It has long been thought that meat played an important role in the diet of hunter-gatherers before the Neolithic transition. However, due to the scarcity of well-preserved human remains from Paleolithic sites, little information exists about the dietary habits of pre-agricultural human groups. A new study challenges this notion by presenting compelling isotopic evidence of a strong preference for plants among 15,000-year-old hunter-gatherers from Morocco. This is the first time a significant amount of plant consumption has been measured for a pre-agricultural population, shedding new light on the dietary practices of ancient human societies.

More Cranberries

Cranberry is associated with multiple health benefits, which are mostly attributed to its high content of (poly)phenols, particularly flavan-3-ols. However, clinical trials attempting to demonstrate these positive effects have yielded heterogeneous results, partly due to the high inter-individual variability associated with gut microbiota interaction with these molecules. In fact, several studies have demonstrated the ability of these molecules to modulate the gut microbiota in animal and in vitro models, but there is a scarcity of information in human subjects. In addition, it has been recently reported that cranberry also contains high concentrations of oligosaccharides, which could contribute to its bioactivity. Hence, the aim of this study was to fully characterize the (poly)phenolic and oligosaccharidic contents of a commercially available cranberry extract and evaluate its capacity to positively modulate the gut microbiota of 28 human subjects. After only four days, the (poly)phenols and oligosaccharides-rich cranberry extract, induced a strong bifidogenic effect, along with an increase in the abundance of several butyrate-producing bacteria, such as Clostridium and Anaerobutyricum. Plasmatic and fecal short-chain fatty acids profiles were also altered by the cranberry extract with a decrease in acetate ratio and an increase in butyrate ratio. Finally, to characterize the inter-individual variability, we stratified the participants according to the alterations observed in the fecal microbiota following supplementation. Interestingly, individuals having a microbiota characterized by the presence of Prevotella benefited from an increase in Faecalibacterium with the cranberry extract supplementation.

Short term supplementation with cranberry extract modulates gut microbiota in human and displays a bifidogenic effect — https://www.nature.com/articles/s41522-024-00493-w

The further I got into reading this study the more I realized it was way over my pay grade.

I’ll sumarize – eat more cranberries because they’re good for you.

My earlier post Cranberries was much easier to understand.
