Brain Detects Disease in Others Even Before it Breaks Out

Because my family history includes both Alzheimer’s Disease and dementia, I am fascinated by every aspect of the brain and its functions. The following is from Neuroscience News.

The human brain is much better than previously thought at discovering and avoiding disease, a new study led by researchers at Karolinska Institutet in Sweden reports. Our sense of vision and smell alone are enough to make us aware that someone has a disease even before it breaks out. And not only aware – we also act upon the information and avoid sick people. The study is published in the scientific journal Proceedings of the National Academy of Sciences (PNAS).

By injecting harmless sections of bacteria, the researchers activated the immune response in participants, who developed the classic symptoms of disease – tiredness, pain and fever – for a few hours, during which time smell samples were taken from them and they were photographed and filmed. The injected substance then disappeared from their bodies and with it the symptoms. NeuroscienceNews.com image is for illustrative purposes only.

Whole grains improve immune response – Studies

Consumption of fast foods and processed foods took another hit today according to a couple of studies from Tufts.

In a clinical trial, adults who consumed a diet rich in whole grains rather than refined grains had modest improvements in healthy gut microbiota and certain immune responses. The research was conducted in tandem with a study that looked at the effects of a whole-grain diet on energy metabolism. Both studies are published online today in the American Journal of Clinical Nutrition.

Whole grain consumption has been associated with reduced risk of heart disease, type 2 diabetes, and some cancers. Researchers have speculated that whole grains lessen risk for diseases through reducing inflammation, but studies comparing the effects of whole grains versus refined grains consumption have not controlled the diets of study participants and have not evaluated cell-mediated immune responses to uncover the impact of whole grains on immune and inflammatory responses.

The research team analyzed the results from an eight-week randomized, controlled trial with 81 participants to see what effect a diet rich in whole grains, as opposed to a diet rich in refined grains, would have on immune and inflammatory responses, gut microbiota, and stool frequency in healthy adults. For the first two weeks, participants consumed the same weight-maintaining Western-style diet rich in refined grains. For the next six weeks, 40 of those participants stayed on that diet, while 41 participants consumed a diet rich in whole grains. Continue reading

How healthy are sweet potatoes?

I have posted on the health benefits of sweet potatoes previously, but, I think good information bears expanding. Here is a very useful infographic.

health-benefits-of-sweet-potatoes.jpg

Here are a couple of highlights, but click on this link for the entire spread.

In addition, WebMD has an informative spread on them, too. Under the  heading Antioxidants Aplenty it offers: “Not all sweet potatoes are orange. Their skins and insides can be white, yellow, brown, red, pink, and purple. The range of color brings different nutrients to the table. Purple-fleshed sweet potatoes are thought to contain super-high levels of antioxidant and anti-inflammatory agents. As these substances pass through your system, they balance out free radicals — chemicals that harm your cells.”

Under the heading Healthy Prep Is Easy it says: “The way you cook your sweet potatoes can make a big difference in the nutrition you’ll get from the dish. One study measured how many carotenoids, like beta-carotene, stayed in the food afterward. The simplest method, oven baking, turned out to be the best.”

Use Vitamin C for a healthy immune system

It’s that time of year again, not just holiday season, but cold season. And, for many of us, it’s vitamin C season. As a person just getting over his Christmas cold, I was interested to learn more about vitamin C. Turns out it is a very powerful force for good health.

main-foods-that-pack-more-vitamin-c-than-an-orange.jpg

Here’s what Marisa Moore, MBA, RDN, LD from the Academy of Nutrition and Dietetics as to say about it.

“Vitamin C, or ascorbic acid, is a water-soluble vitamin well known for its role in supporting a healthy immune system. Because your body cannot make vitamin C, it must come from the foods you eat every day. Continue reading

10 Top Health Benefits of Broccoli – Infographic

Popeye had his spinach, but broccoli is really healthy, too.

There are lots of fancy ways to fix it, but my favorite, that is to say, Mr. Lazy Cook’s favorite, is to steam it a couple of minutes and dig in. If you aren’t familiar with steaming, it is wonderfully quick and brings out the most brilliant colors in your veggies.

Health Benefits of Pineapple in Arthritis Management and Others

One of the most celebrated uses of pineapple in terms of health is its ability to reduce the inflammation of joints and muscles, particularly those associated with arthritis, a truly debilitating disease that affects millions of people around the world.

As a long time arthritis (hands) sufferer, I drink pineapple juice daily. It’s nice to see all the benefits of this tasty fruit.

One of the most celebrated uses of pineapple in terms of health is its ability to reduce the inflammation of joints and muscles, particularly those associated with arthritis, a truly debilitating disease that affects millions of people around the world.

Pineapples contain a relatively rare proteolytic enzyme called bromelain, which is primarily associated with breaking down complex proteins, but it also has serious anti-inflammatory effects, and has been positively correlated with reducing the signs and symptoms of arthritis in many test subjects.

Green Ginger Grapefruit Smoothie – Guest Post Kelli Jennings

Regular readers know that I am a nearly daily bike rider here in Chicago. As such I read some cycling blogs, too. One of my faves is Loving the Bike.

And, one of that blog’s regular contributors is Kelli Jennings, an Expert Sports Nutritionist who writes Ask the Sports Nutritionist.

Kelli is not only a world class athlete, but also a first rate nutritionist who writes clearly and accurately about her subject.

She recently wrote an item Green Ginger Grapefruit Smoothie   that I thought would interest you.

I hate to be a downer, but I’ve got some bad news.  Grapefruits are tough to come by in the summer.  The prices go up and they’re not as plentiful.  I know, this likely ruined your Thursday.  I guess the only thing to do is eat ‘em up, while you can.

This week, we’ll review why grapefruits should be one of your go-to fruits and we’ll “wake it up” with a wonderfully refreshing grapefruit smoothie.  Grapefruits go above and beyond the nutrients of many foods, even other ones found in produce section.  Did I mention they can help you lose weight?  Bring on the grapefruits!

Recipe of the Week: Green Ginger Grapefruit Smoothie

Ingredients:
3/4 cup Greek yogurt or 1/2 scoop protein powder
1/2-1 pink grapefruit, peeled well
3/4 cup berries
1/4 avocado
1 cup spinach or other greens
1/2″ slice ginger
2 Tbsp chia seeds
1/2 cup water ice, if desired for consistency

Instructions:
Place all ingredients in the blender and process until smooth. Enjoy!

Nutrition information: Approximately: 385 calories, 44 gm carbs, 11 gm fiber, 15 gm protein.

Comments:

1) In the picture, this smoothie is obviously not green. I call it “green” because it includes a grapefruitsmoothie1-225x300whole cup of green. The berries’ color overtake the green. Either way, it’s not easy being green, and it’s all good stuff.

2) This is not Jamba Juice. If you want your smoothie to taste like Jamba Juice, you’ll have to go there and pay for a smoothie much higher in sugar and processed ingredients. If not, I think you’ll feel refreshed and satisfied having started your day with some ginger, greens, and grapefruit. I know I do!

Next, there’s lots of good reasons to eat grapefruits while you still can. On the list, is potential weight/fat loss. You’ve heard of the grapefruit diet, right? Eat grapefruits and lose weight. And of course, most cyclists wouldn’t mind losing fat and improving strength to weight ratio. But, is it science or quackery? Is there something magic to the grapefruit? Well, you can rest assured that I’m certainly NOT recommending you eat nothing but grapefruits. But, it may help to add them. Here’s some food for thought: Continue reading
