YOU ARE WHAT YOUR GRANDPARENTS ATE

The following post expresses the views of a blog titled Doctor’s Digest and not necessarily the views of Food, Facts and Fads. However, in the field of nutrition, there are always many controversies and it is wise to keep these in mind when seeking diet advice. The following article presents some concepts that are not yet proven by research; however, the future of epigenetics may provide more insight into these hypotheses. The source was based on the book, You Are What Your Grandparents Ate that was sent to me by the authors for review. See the Source below.

In other words:

“This book explains why we are suffering the largest health epidemic in human history, why we need better wholesome foods to buy, why we need better food policy and why we must pay careful attention to the health and nutrition of our young women and men as they prepare to bear the next generation.”

Nutrition News: No Nonsense

Are those eggs OK to eat?

Too many of us end up throwing out food that is still perfectly safe to eat. Eggs are often on the top of the list of things people think go bad quickly. But eggs are safe to eat up to five weeks after the sell by date. If you’re curious about when those eggs were packed just look at the number under the sell by date, the three-digit number in the middle.

The problem with potassium.

Many people load up on bananas and potatoes because they are high in potassium, which can help lower blood pressure. But more isn’t always better. Too much potassium can cause irregular heartbeat and other side effects. While the National Institutes of Health has not released an upper limit for potassium, the supplements in the US do not contain more than 99 milligrams. Taking more potent forms can have serious adverse side effects including confusion, temporal paralysis, low blood pressure, weakness, and coma.

Reduce Your Risk of Stroke

What is the biggest benefit of getting enough protein? If you said building muscles, you’d be close, but it might not be the biggest benefit. Recent studies show people who ate the most protein had higher levels of HDL ( good cholesterol) and those who eat the most protein (not including red meat ) were 20% less likely to suffer a stroke than those with the lowest intake. What’s more, people who ate more protein and fewer carbohydrates had better numbers for blood pressure, LDL cholesterol, and triglycerides.

Bacon as Bad as Smoking?

Is that slice (or two or three) of bacon on your BLT as dangerous as smoking a cigarette? Processed meats like bacon and cold cuts are listed as a Group One carcinogen, the same as smoking or asbestos. But that doesn’t mean they’re equally as dangerous. The classification reflects the strength of evidence linking processed meats – think: bacon, sausages, hot dogs, jerky, and cold cuts to cancer risk. Basically, any meat that’s been tweaked to enhance the flavor or improved preservation by salting, curing, fermentation or smoking is considered processed. Just one 0.75 ounces of bacon (about two slices a day) is linked to an 18% greater risk of colorectal cancer. That’s the equivalent of 1 hot dog or a couple slices of cold cuts. While it isn’t a good idea to load up on these foods, they’re often high in saturated fat and salt too, let’s put the risk in perspective. The lifetime risk of an average American of developing colorectal cancer is 5%. An 18% increase raises that number to about 6%, so an occasional ballpark dog or B LT should be fine. Important note: simply choosing nitrate-free meats may not reduce your risk of cancer. High temperature cooking methods like pan frying and grilling may produce more carcinogens in meat. Choosing lower temperature cooking methods like braising or roasting may reduce your risk. Ever tried cooking bacon in the oven? Works well!

Zinc can help boost your immunity as you age.

A new study showed that 30% of nursing home residents have low blood levels of zinc, and those with low levels were at significantly higher risk of pneumonia. Ensuring adequate zinc consumption could reduce chances of deadly infections. Zinc helps to improve the function of T-cells, a special type of white blood cell that targets and destroys invading bacteria and viruses. Zinc supplementation not only increased the number of T- cells, but it improved effectiveness, too. Get more zinc in your diet with shellfish, pork, cashews, peanuts, and chickpeas.

Is All Sugar Equal?

Simple sugars are considered simple because they are small molecules that require little or no digestion before they can be used by the body. They come in two types: monosaccharides and disaccharides. First, here is a little sugar biochemistry.

Types of Carbohydrates

Carbohydrates are chemical compounds that contain carbon, hydrogen, and oxygen. Simple carbs, also called sugars include monosaccharides (fructose, glucose, and galactose) and disaccharides (sucrose, lactose, and maltose). They are found in foods such as table sugar, honey, milk, and fruit.

Complex carbohydrate include oligosaccharides and polysaccharides. Glycogen is a polysaccharide found in animals, and starch and fiber polysaccharides are found in plants. Sugars and starches consumed in food are broken down in the digestive tract to monosaccharides which can be absorbed in the bloodstream.

The simple sugars the body uses directly to form energy are glucose and fructose. Galactose is readily converted to glucose by the body. So, basically, all sugars and starches (chains of glucose) end up as glucose in the body. When the body has more glucose than it needs for energy, it converts the excess to fat and and glycogen. The glycogen is stored in the liver and muscles. When the body needs energy, glycogen is broken down making glucose available for energy formation. Glucose can also be obtained from certain amino acids and the glycerol part of fat. A constant supply is needed for the brain, red blood cells, white blood cells and some special cells in the kidney.

What are Added Sugars?

It is now a requirement to state the amount of added sugars on the Nutrition Facts Panel of most food products. Most of the simple sugars in our diet comes from foods and beverages sweeteners as sucrose and high-fructose corn syrup. Added sugars make up 15% of the total caloric intake of Americans.

High-fructose corn syrup is a liquid sweetener found in many soft drinks, fruit drinks, breakfast cereals and other food products. It consists of 55% fructose and 45% glucose, compared to sucrose that contains 50% glucose and 50% fructose. For example, one 12 oz serving of a soft drink contains about 9 teaspoons of sugar. That’s a lot of sugar and far more than is good for health.

The American Heart Association recommends that women consume no more than 6 teaspoons a day and men only 9 teaspoons a day.

Nutrition News in Brief

Drinking Tea and Healthy Brains

Tea has been a popular beverage since antiquity dating back to the dynasty of Shen Nong (2700 BC). Drinking tea has become increasingly popular in western countries today. It is assumed that the types of tea were both black and green teas; however, this was not designated in the abstract below.

A study from the journal Aging reported that drinking tea was associated with a healthy brain.

Method: The current study compared 15 tea drinkers aged 60 and older to 21 people in the same age group who did not regularly consume tea.

The researchers gave neuropsychological tests to the participants that evaluated cognitive function and used magnetic resonance imaging (MRI) to assess brain connectivity.

Results and Conclusion

The tea-drinking group had better organized brain regions and cognitive functions compared to those in the group who were not tea drinkers.

The authors stated: “Our results offer the first evidence of positive contribution of tea drinking to brain structure and suggest that drinking tea regularly has a protective effect against age-related decline in brain organization.”

Blueberry Intake May Reduce Cardiovascular Risk

A study reported in the American Journal of Clinical Nutrition found a lower risk of cardiovascular disease among men and women with metabolic syndrome who consumed the equivalent of a cup of blueberries daily for six months. Metabolic syndrome is a collection of health risks, including high blood pressure, altered blood lipids, high blood glucose and a large waist circumference, that increases the chance of developing heart disease, stroke and diabetes type 2.

Method: A total of 138 individuals were randomized into groups that were given either 26 grams of powdered blueberries (equivalent to a cup of fresh blueberries), 13 grams of powdered blueberries plus 1/2 cup of a mock blueberry placebo, or 26 grams of the placebo.

Insulin resistance, flow mediated dilatation (a measure of endothelial function), augmentation index (which measures artery stiffness), cholesterol and other factors were measured before and after the intervention. Endothelium refers to the cells that line the interior surface of blood vessels in the body as well as the lymphatic vessels

Results: The researchers observed an improvement in endothelial function and arterial stiffness in the group that received 26 grams of blueberry powder.

Conclusion: The authors stated: “The simple and attainable message to consume one cup of blueberries daily to consume one cup of blueberries daily should be given to those aiming to improve their cardiovascular health.”

How to Like Vegetables?

Americans need all the help they can get in eating more vegetables (nutrient dense, low in calories, loaded with fiber). If you have children, It’s even more important My personal advice?

Roast them – they caramelize and take on a whole new flavor and texture. Add a little honey and/or butter for more appeal. And it’s so easy on a foil-lined baking pan. Easy clean-up, too. – yes it can be done.

Enjoy the advice and bon appetit.

Nutrition Myths

It is time to put to rest some nutrition misinformation that has dominated the media for a number of years now. Here is the nonsense and the sense of some of the most prevalent myths – it’s time to move away from them.

Gluten -Free Foods are Healthier. Unless you are truly sensitive to gluten or have been diagnosed with celiac disease, you may miss out on some healthy whole grains if you choose gluten-free foods.

You only need to limit salt intake if you have high blood pressure. 90% of us will develop high blood pressure and some of us are sodium sensitive. We get plenty of sodium in processed foods and should try to limit our total intake to no more than 2,300 milligrams a day.

Sugar is toxic. There is no evidence that shows that sugar causes disease on its own. However, a high sugar intake can replace the healthier habits of learning that carbohydrate intake can be healthier if we consume more complex carbs (fruits, whole grains, vegetables) and less highly refined carbs (sugary drinks and foods with added sugars).

Fresh Produce is healthier than canned or frozen. Foods which are picked fresh and immediately canned or frozen may even have more nutrients than fresh produce. In fact, your body more easily absorbs nutrients like lycopene when they’ve gone through the canning process.

The term “natural” means healthier. The term natural on a food label has no FDA defintion, so it has no meaning in terms of health or that it is “organic.”

Farm-raised fish isn’t healthy. Today’s farm-raised fish has just as much and maybe more healthier omega-3 fats than wild-caught. Also farm-raised fish may have less mercury. They are now more sustainable and when from reputable farms can be raised with fewer antibiotics and no added coloration.

Margarine is loaded with unhealthy trans fats. This depends on whether the margarine is in stick form or tub form. A better choice is the softer tub margarine that is less hydrogenated and thus has less trans fat than the more saturated and trans fat content found in the stick form.
