Tropical Oils
This is the latest on tropical oils. I think the key word again is moderation, limit your use of all oils to a minimum and stick to the healthiest oils like olive and grapeseed, and canola. But have fun with the other flavors out there too!

Tropical oils are being touted as a healthier alternative to partially hydrogenated oils, which contain trans fats. Are they really better for you?
Tropical oils were once the favored fats for giving processed foods a pleasing texture and good shelf stability. But starting in the late 1980s, these oils fell out of favor because most of the fats they contain are saturated, and saturated fats were linked to elevated blood cholesterol. Partially hydrogenated oils, which largely replaced tropical oils at the time, were subsequently found to be even worse for your heart because of their trans fat.
Now, tropical oils are back again. You can find them in an increasing number of packaged foods, including crackers, cookies, pie crusts, energy bars and spreads, as well as microwave and movie theater popcorn.
Tropical oils: understudied and unclear
Lab research suggests that palm oil, though highly saturated, may act more like healthful unsaturated fats in the body, in terms of its effects on blood cholesterol. But the evidence is conflicting. One study from Brazil, for example, found that palm oil improved cholesterol in healthy people. In contrast, a study from Thailand found it increased cholesterol in women who already had high cholesterol. Meanwhile, population studies have not consistently linked consumption of palm oil to heart disease. In reality, there have been too few human studies in English-language journals to know if palm oil is detrimental, neutral or possibly even beneficial.
Published research on coconut oil is even more scant. In one study, in Lipids, women who consumed coconut oil for 12 weeks had no undesirable changes in cholesterol. And in some countries where people consume a lot of coconut oil, cholesterol levels tend to be low. There’s no evidence, however, that coconut oil strengthens immunity, improves digestion or prevents heart disease, arthritis or other chronic diseases, as some websites claim. Due to its chemical structure, it does take a few more calories for the body to process coconut oil, compared to other fats—but any calorie-burning effect would be minimal at best. It is certainly no treatment for obesity.
A breakdown of tropical oils
All fats are mixtures of saturated and unsaturated fatty acids. Though most of the fatty acids in tropical oils are saturated, not all saturated fats are harmful. In some studies, palm oil’s main fatty acid, palmitic acid, had no effect on cholesterol. Palm oil also contains a fair amount of monounsaturated fats. Similarly, though coconut oil is highly saturated, its fats seem to have a neutral effect on cholesterol levels in most people.
Moreover, the effect of saturated fat varies from person to person, depending on genetics, weight, other dietary and lifestyle factors and even gender. In addition, tropical oils contain other substances that can affect the risk of heart disease—and how the oils are processed may matter, too. What’s key is your overall diet. Adding tropical oils in the context of a healthy diet is unlikely to affect blood cholesterol significantly.
Our advice
Early research that raised red flags about tropical oils was faulty. You should still limit these oils, however, since their effects on cholesterol aren’t fully understood. And snack foods containing tropical oils tend to be high in calories—and low in nutrients. Be aware, also, that manufacturers may use a process called interesterification, which changes the structure of the oil so that it performs like a partially hydrogenated oil without the trans fat. That sounds great but we don’t yet know whether interesterified fats might have their own adverse health consequences. If you see the term “fully hydrogenated” palm or palm kernel oil on a food label, it may indicate that interesterified fats are present.

Healthy Tidbits
We know about yogurt as a probiotic but sourdough bread?
Sourdough Bread Aids Digestion
The next time you make a sandwich, pay attention to what's holding your cold cuts and cheese. San Francisco's famous sourdough bread contains lactobacilli, a probiotic which may benefit digestion.(Web MD)

Grand Tetons and Yellowstone National Parks
We took another road trip, this time to Yellowstone National Park and the Grand Tetons last week. Beautiful country! Part of the trip was spent in a photo workshop of Yellowstone. The theme was wild life photography. We saw mostly Buffalo, but also Elk, Coyote, Prong horn deer, Bald Eagle and other wildlife.We started our trip in the Grand Tetons park and stayed at Jackson Lake Lodge, very nice.
This is the view from our bedroom picture window!
I wish I could write more about the food we ate while on our trip but alas, the food was marginal. I am sure there are some good restaurants there but with limited time on our hands they were hard to find.
The landscape at Yellowstone was not only spectacular but a little 'creepy' with all the hot springs in the park. As you drive thru the park there are plenty of bubbling pools of hot volcanic water and steam!
I found out that the park sits on a live volcano which is due to erupt one of these days! We watched 'Old Faithful' geyser and had lunch in the historic Old Faithful Inn. Very cool place.

Green Exercise
It is so much more exhilarating to walk outside in the woods or on a beach! You don't even need a walk man to occupy your mind. (probably because you are watching out for bears)!
(Berkeley Wellness)
Exercise is good for your body and mind. But exercising in nature can be especially restorative, recent research shows.
Lately, researchers have been looking at what happens to our brains and bodies when we’re walking in a forest, in the mountains or by the sea. The study of such “green exercise” usually falls under the umbrella of environmental psychology (or ecopsychology). The Japanese, in particular, have been studying what they call “forest bathing” (Shinrin-yoku)—that is, spending time in nature for therapeutic effects.
Studies have found, for instance, that people do better on tests involving memory or attention after trekking through the woods than after walking in a city. People have increased vitality (that is, physical and mental energy) and a greater sense of well-being after walking through a tree-lined river path than after walking indoors. Other studies have even found that patients in hospitals tend to recover more quickly when they can see trees from their windows.
The proposed benefits of green exercise include giving the brain a respite from the multi-tasking of everyday life. If you enjoy hiking, you know that you become more aware of your surroundings—the sounds, smells, colors. Time slows down. Somehow this refreshes the brain and makes thinking clearer. Japanese researchers have found that walking through forests can help reduce stress, lower blood pressure and heart rate, and improve various aspects of immune function for anywhere from a few hours to a few days afterwards—while walking in a city does not. They suggest that various airborne chemicals emitted from plants may play a role.
All it takes is 5 to 20 minutes of green exercise to boost mood and energy levels somewhat, some research has found, though longer forays in nature produce greater benefits. Other studies indicate that there’s a “third-day effect”—a special stage of relaxation and mindfulness that occurs after a couple days of hiking. Being out of the range of cell phones and email may be a factor, too.
Not everyone enjoys hiking or can do it, of course. Other green exercise activities—by the shore or even in a city park—may be your thing. Find what kind of environmentalist you are, and enjoy.

Breakfast at Firesign Cafe
We had another great breakfast at Firesign Cafe on the west shore of Lake Tahoe. We have been eating here for 20+ years, that should tell you how great it is! I love their waffles and I had the granola waffle with real maple syrup. Ron had their special potato and vegetable scramble with eggs which came with their yummy coffee cake. Their portions are plenty big! How great is sitting outside on their deck in beautiful Lake Tahoe having a hearty breakfast!
