For The Love of Food

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

My heart goes out to those affected by the shooting this morning in Newton, Connecticut.

This week the food industry can’t handle the truth, false memories can make you feel more full or hungry, and why vegetables may be good for bone health.

“I’ve always wondered what the scientific perspective of alcohol consumption is. I have been doing some research but the actual effects of it on the body range from beneficial to cancerous.”

The clinical science on alcohol consumption is vast and diverse. It’s easy to find studies that demonstrate the benefits of alcohol, but it is equally common to find research showing its dangers. Sorting through the data is not trivial, and getting the right answer from news reports is virtually impossible.

Let’s start with the facts:

1. Alcohol is addictive

Alcohol addiction is one of the most well-understood and dangerous risks of drinking. A propensity for addiction can run in families, but can affect anyone who drinks in excess. None of the health benefits of alcohol can negate the destruction caused by addiction, and anyone who drinks should be careful to avoid this terrible condition.

2. Alcohol damages the liver

Alcohol metabolism occurs in the liver and can cause severe damage when consumed in large quantities. Liver damage can usually be reversed if alcohol consumption stops.

3. Alcohol is associated with breast cancer (sort of)

Drinking is weakly associated with an increased risk of breast cancer. This is likely because alcohol increases aromatase activity in the human body, which increases estrogen production. Estrogen imbalance is a known cause of breast cancer. However, the association between drinking and breast cancer is negated by sufficient folate intake. Folate or folic acid is a B vitamin found in leafy green vegetables, fruits and legumes (and fortified foods). In other words, a healthy diet protects against alcohol induced breast cancer risk.

4. Alcohol protects against mortality from heart disease

Drinking alcohol reduces your risk of dying from a heart attack by preventing blood clotting. This effect is not limited to red wine, all spirits elicit substantial protection. The association appears to be dose-dependent, meaning that the more you drink the more protection you get. HOWEVER, you start raising your risk for the above mentioned problems with every additional drink per day. For men the ideal dosage is 2 drinks per day, for women it is 1 drink per day.

5. Alcohol raises good HDL cholesterol

Moderate drinking also reduces your risk of getting heart disease in the first place by raising beneficial HDL cholesterol without raising LDL cholesterol. Low HDL is a serious problem in America, and alcohol could be a significant benefit for some people. Here are other ways to raise your HDL cholesterol.

6. Red wine may slow aging

Aging research has been revolutionized by the discovery of a compound in red wine called resveratrol. Resveratrol has been shown to slow aging substantially in several model organisms. Though the effect in humans is still unknown, red wine is associated with many benefits that seem to go above and beyond the benefits of alcohol in general.

7. Red wine may protect against Alzheimer’s disease

Several studies have shown that red wine is associated with a decreased risk for Alzheimer’s Dementia, a devastating neurodegenerative disease that affects 1 in 4 people over the age of 90. The mechanism of action is unclear, but the benefits may be linked to the effect of red wine on fatty acids in the blood (raising the good stuff), or by slowing the aging process itself.

8. Alcohol causes accidents and behavioral problems

Even relatively safe levels of drinking can be deadly when combined with poor decision making. If you do choose to drink alcohol, always be sure that you’re in a safe environment and can get help if you need it. Being safe sometimes, or even usually, is simply not good enough.

There are plenty of good reasons to avoid alcohol if you choose, and many of the benefits can be garnered by simply increasing the amount or intensity of your daily physical activity.

However, the evidence is pretty clear that moderate alcohol consumption (1-2 drinks per day) can improve health and may be an important component of a healthy lifestyle. This is even true for those who pick up the habit later in life.

And last but certainly not least, some of the best times of my life have been over a drink with friends. And I guarantee you most of us aren’t thinking about our heart health while enjoying a great bottle of wine. As long as you consider safety first, never forget that smiling is one of the healthiest things you will ever do.

Here’s a fun question: what’s your favorite drink??

• Some HDL, or ‘Good’ Cholesterol, May Not Protect Against Heart Disease <<For those interested in the biochemistry of heart disease, this is an absolutely fascinating new discovery regarding HDL. Looks like current tests really aren’t sensitive enough. (ScienceDaily)

Last week we talked about the pros and cons of eating soy including it’s role in breast cancer and it’s affect on the, errr, manly arts.

As always, show notes are below.

July 19, 2011 | Tonight on Summer Tomato Live we’re discussing soy. Some say it prevents cancer, others think it promotes it, and some claim it’s evil for causing man boobs. We’ll get to the bottom of these issues and more today during the show.

Join us at 6:00pm PST to learn about how soy affects your health and what to do about it.

To watch live and join the discussion click the red “Join event” button, login with Twitter or your Vokle account, and enter the password when prompted.

I encourage you to call in with video questions, particularly if your question is nuanced and may involve a back and forth discussion. Please use headphones to call in however, or the feedback from the show is unbearable.

See you soon!

Soy sauce

Someone asked during the show how this advice applies to soy sauce. Turns out there are 2 different methods of brewing soy sauce. The traditional way is fermented and has the same attributes as fermented soy products mentioned in the episode. The other method creates the sauces by hydrolyzing soy, which creates a number of unwanted byproducts including MSG and potentially some carcinogenic chemicals. The Wikipedia article on soy sauce is very informative.

One of the biggest fears men have about eating soy is the possibility of phytoestrogens demasculizing men, creating sexual dysfunction, infertility and the dreaded man boobs.

Indeed, there have been several studies in rodents suggesting that soy can interfere with reproductive pathways and fertility. However, human and monkey studies show that most men have no need to fear soy.
