For The Love of Food

Welcome to Friday’s For The Love of Food, Summer Tomato’s weekly link roundup.

This week some interesting new data on the ideal amount of salt to eat, frightening news about BPA and canned soup, and a series of fascinating articles on how to maintain cognitive health.

Want to see all my favorite links? Be sure to follow me on on Digg. I also share links on Twitter (@summertomato), Google+ and the Summer Tomato Facebook page. I’m very active on all these sites and would love to connect with you.

Links of the week

• Study Calls Sodium Intake Guidelines Into Question <<I’ve always been skeptical of the super low sodium recommendations suggested by the USDA and other agencies. Processed food is always a major cofounder, and likely the real problem. (ScienceDaily)
• BPA Levels Spike After Eating Canned Soup: Study <<Wow, this is no small difference. I think it is time to majorly reconsider eating anything from a BPA-containing can. (Medline)
• Cigarettes may be useful for distance runners?!? (or, How to prove anything with a review article) <<This is an excellent piece about the dangers of over-interpreting correlations (e.g. all epidemiological data) in science. (Obesity Panacea)
• Low vitamin D linked to heart disease, death <<This is interesting because, for once, it shows a benefit of taking supplements to protect health. (Medline)
• Americans’ ‘ideal weight’ shifts upward <<I find this very disturbing, though not surprising. Look at photos or videos from 30 years ago and most of the people would be considered “too thin” by today’s standards. But they were much healthier. (Los Angeles Times)
• How Exercise Benefits the Brain <<Workouts are important for more than just looking great, they can also help you perform better at work or school. (New York Times)
• Non-Fried Fish Might Help Ward Off Alzheimer’s: Study <<Surprisingly low amounts of fish consumption were shown to be beneficial in preventing cognitive decline. (Medline)
• It Could Be Old Age, or It Could Be Low B12 <<Another interesting piece regarding the importance of nutrition in maintaining cognitive ability, this time vitamin B12. (New York Times)
• This is your mind on meditation: less wandering, more doing <<I’m a big advocate of mindful eating, but mindfulness can also be important in helping you focus in general. (Los Angeles Times)
• Barley Risotto <<Such a lovely, hearty winter dish. Looks delicious. (Mark Bittman)

For The Love of Food

Welcome to Friday’s For The Love of Food, Summer Tomato’s weekly link roundup.

This week’s top 10 require careful reading and a little extra thinking, but it’s worth it. Learn why daily activity is more important than formal exercise, how habits can affect your food intake, some encouraging news from the USDA and more.

Want to see all my favorite links? Be sure to follow me on on Digg. I also share links on Twitter (@summertomato) and the Summer Tomato Facebook fan page. I’m very active on all these sites and would love to connect with you.

Links of the week

• Routine Chores Might Help Keep Dementia at Bay <<This title is misleading, because the most interesting part of this story is that daily activity is more effective than formal exercise for burning calories. Also, this preserves your mind. (Medline)
• People eat out of habit, a study finds, even when food is stale <<This is exactly why I’m always encouraging you to eat mindfully. Interestingly, in this study even eating with your non-dominant hand seemed to help. (Los Angeles Times)
• Nutrition: A Low-Calorie Meal Is Shown to Pay Off <<BS of the week. I’m all for eating less and I think you can be successful at it, but this is a poorly designed study using junk food as a meal and it only lasted 2 weeks. How that can be considered “effective” is beyond me. (New York Times)
• USDA seeks method to compensate farmers for GM contamination <<Remember in the movie Food Inc. when Monsanto sues an organic farmer because their seeds contaminated his crop? Hopefully this works out and puts and end to ridiculous things like that. (Food Politics)
• Why I never eat breakfast cereal. <<Breakfast cereal isn’t really food, and my friend Yoni who works with obesity patients for a living thinks it may also prevent weight loss. Worth considering. (Weighty Matters)
• Eating purple potato may lower blood pressure for the overweight <<This really isn’t necessarily restricted to purple potatoes. What it shows is that at least some potatoes aren’t as bad for you as bread. (Los Angeles Times)
• Helpful Gut Microbes May Differ Based on Diet <<I find this new area of research absolutely fascinating. This study shows heavy meat eaters have different microbial gut patterns than herbivores. At this point there’s no reason to prefer one to the other, but down the line it may help explain why dietary patterns are more important to your health than short-term changes. (Medline)
• Vitamin D levels tied to colon cancer risk <<Yet another reason to be sure your vitamin D levels are in a healthy range. Mine weren’t until I started taking supplements. (Medline)
• Hyperinsulinemia: Cause or Effect of Obesity? <<For geeks’ eyes only. Understanding this article requires a fairly sophisticated understanding of human metabolism and biochemistry, but if you have those things and are interested in exploring some of the fallacies of Gary Taubes’ carb argument, you’ll love this one. (Whole Health Source)
• roasted tomato and thyme soup <<A beautiful looking recipe, though I would personally leave out the sugar since tomatoes are so sweet right now. (the sophisticated gourmet)

Show notes:

There is a huge amount of politics surrounding this science, because of the powerful influence of dairy industries around the world. This makes data difficult to interpret. The following review and its rebuttal regarding the role of milk in type 1 diabetes is a perfect example of what I mean:

Dairy & type 1 diabetes

• Literature review

• Vitamin D, calcium, fruits and vegetables, protein important for bone health
  • http://www.ncbi.nlm.nih.gov/pubmed/19968914
• Diet “acidity” (from protein & other sources) is not a factor in osteoporosis
  • http://www.ncbi.nlm.nih.gov/pubmed/19754972

Dairy and acne

• Dairy consistently shown to promote acne, probably via hormonal mechanisms
  • http://onlinelibrary.wiley.com/doi/10.1111/j.1365-4632.2009.04002.x/full
• Treat acne with low GI foods (skip sugar & flour) and omega-3 fatty acids

Dairy/calcium and heart disease

• Calcium supplementation increases CVD risk
  • http://www.ncbi.nlm.nih.gov/pubmed/20671013
  • http://www.bmj.com/content/341/bmj.c3856.long

Dairy/calcium and prostate cancer

• Milk from cows given rBGH (hormone from Monsanto) increase cancer risk
  • http://www.preventcancer.com/press/releases/july8_98.htm

Dairy & weight loss (very tough to find studies not funded by dairy industry)

• Moderate weight loss from dairy (but rarely from intervention studies w/o caloric restriction)
  • http://www.ncbi.nlm.nih.gov/pubmed/21320381
• Possible mechanisms include:
  • Ca++
  • protein
  • conjugated lineoleic acid (CLA)
  • medium-chain fatty acids
• My interpretation: dairy not likely to have big impact on body weight

Cheese protects against cancer and heart disease?

For The Love of Food

Welcome to Friday’s For The Love of Food, Summer Tomato’s weekly link roundup.

Tough decisions were made this week to narrow it down to 10 stories. Love the calorie infographic, also the commentary by Dr. Ludwig on industrial food and the “small” 32 oz. soda at a SF movie theater.

Want to see all my favorite links? Be sure to follow me on on Digg, Twitter (@summertomato) or the Summer Tomato Facebook fan page. I’m very active on all these sites and would love to connect with you.

Links of the week

• Where Do Americans Get Their Calories? (Infographic) <<This is REALLY cool. Notice grain consumption increased nearly 50% (just like the AHA recommends), same with added fat (aka processed vegetable oils) and sugars. Veggie intake hasn’t changed, nor has dairy, and barely “meat, egg and nuts”. Fruit has gone up. Sounds like we’re obeying the food pyramid, yet eating 25% more calories and gaining weight and disease faster than ever. Lovely. (CivilEats)
• Food technology has been bad for human health since long before the invention of high-fructose corn syrup <<The wonderful Dr. Ludwig tells a more complete story about the nature of obesity. It’s not just the fructose. (Los Angeles Times)
• Food is cheap at market, but costs a lot elsewhere <<Food prices are going up, but are you confused why experts say calories are “cheap”? Learn the gory details from Marion Nestle. (SFGate)
• When did a “small” soft drink become 32 ounces? <<This saddening fact qualifies for BS of the week. Like seriously, this is disgusting. (SFGate)
• Sweet! Candy eaters surprisingly slimmer <<Interestingly, this study relied on a 24hr recall questionnaire, meaning that it didn’t actually test candy eating, but the awareness of candy eating. Mindful eating may be the key factor. (MSNBC)
• Vitamin D Can Decrease — Or Increase — Breast Cancer Development and Insulin Resistance, Study Finds <<Just in case you needed more convincing, relying on supplements is scary (especially if you over do it). (ScienceDaily)
• Food Day Campaign is Launched! <<Think real food is important? Me too! We now have a day to celebrate it! (CSPI)
• Routine Periodic Fasting Is Good for Your Health, and Your Heart, Study Suggests <<Fasting data is a lot more convincing than the “eat every 2-3 hrs” data. Just saying. (ScienceDaily)
• Substance in Tangerines Fights Obesity and Protects Against Heart Disease <<It would be nice if stuff like this ever panned out. We’ll see. (ScienceDaily)
• Not Your Mama’s Deviled Eggs <<I completely love deviled eggs, and these sound absolutely divine. Cheers to springtime (The Novice Chef)
