70 is the new 60 (but not for everyone in the U.S.)

“The 21st century is a great time to be alive”

From Market Watch:

Better living conditions, easier work, and better health care are all helping shave years off our effective ages, researchers have said. The progress is steady and consistent, they have found. A typical American woman of 67 today is about as healthy as her mom was at age 60, and at 89 she’s likely to be as healthy as her mom was at 75, the report released this week said.

Health-wise, older people are 10 years younger than their grandparents. “A 70-year-old born in 1960 is predicted to be about as healthy as a 60-year-old born in 1910,” the authors wrote. The authors, Ana-Lucia Abeliansky, Devil Erel and Holger Strulik, economists and statisticians at the University of Goettingen in Germany, crunched medical data on thousands of Americans.

Elderly African-Americans didn’t see the youthfulness gain.

Furthermore:

From 1950 to 2000, average life expectancy has risen more in Western Europe than in the U.S. Europeans have gained 11.3 years, on average, compared with 8.6 years for Americans.

Testosterone Supplementation May REDUCE Risk of Prostate Cancer

…which is contrary to what we’ve been told for years.

From Nature:

The relationship between testosterone therapy and prostate cancer continues to challenge historic and current beliefs. A new cohort analysis revealed a ~33% reduction in prostate cancer incidence in men with increased testosterone use. The mechanisms underlying this protective effect are unclear, but these findings challenge current paradigms and warrant further investigation.

Dietary Fiber Promotes Weight Loss on Calorie-Restricted Diets

Almost no fiber in these cookies

ABSTRACT

Background

The effects of dietary composition on weight loss are incompletely understood. In addition to energy intake, fiber intake, energy density, macronutrient composition, and demographic characteristics have all been suggested to contribute to weight loss.

Objective

The primary aim of this analysis was to assess the role of dietary fiber as a predictor of weight loss in participants who consumed calorie-restricted diets (−750 kcal/d from estimated energy needs) for 6 mo, using data from the POUNDS Lost (Preventing Overweight Using Novel Dietary Strategies) Study—a randomized trial that examined the effects of calorie-restricted diets varying in macronutrient composition on weight loss in adults.

Methods

Data were randomly partitioned to a training data set (70%) in which the effects of fiber and other weight-loss predictors were identified using adjusted Least Absolute Shrinkage and Selection Operator and model averaging. The retained predictors were then fit on the testing data set to assess predictive performance.

Results

Three hundred and forty-five participants (53.9% female) provided dietary records at baseline and 6 mo. Mean ± SD age and BMI for the full sample was 52.5 ± 8.7 y and 32.6 ± 3.9 kg/m2, respectively. Mean ± SD (99% CI) weight change at 6 mo for the full sample was −7.27 ± 5.6 kg (−8.05, −6.48 kg). The final, best fit model (R2 = 0.41) included fiber, energy density, fat, age, adherence, baseline weight, race, and changes from baseline in carbohydrate, fiber, PUFA, and MUFA intake, but the most influential predictor was fiber intake (⁠β̂  = −0.37; P < 0.0001). In addition, fiber was strongly associated with adherence to the macronutrient prescriptions (P < 0.0001). Interactions between race and adherence, age, baseline weight, carbohydrate, energy density, and MUFAs were also retained in the final model.

Conclusion

Dietary fiber intake, independently of macronutrient and caloric intake, promotes weight loss and dietary adherence in adults with overweight or obesity consuming a calorie-restricted diet.

Can Diet Prevent Chronic Kidney Disease and Albuminuria?

Once your kidneys start to go, life gets complicated. There are certain nutrients you need to avoid overdosing on (e.g., potassium). Your drug doses may need to be adjusted. You may retain fluid, causing high blood pressure, swollen legs, and trouble breathing. You may end up needing dialysis, which is a major pain in the ass.

One early sign of kidney disease in some cases is leakage of albumin (a protein) into the urine.

A healthy diet may help preserve kidney function. But what to eat?

The diet described in this Renal and Urology News article sounds like the Mediterranean diet to me.

Adhering to a healthy diet may reduce the risk of chronic kidney disease (CKD) and albuminuria, according to a new systematic review and meta-analysis.

Such a diet is rich in vegetables, fruit, legumes, nuts, whole grains, fish, and low-fat dairy products and low in red and processed meats, sodium, and sugar-sweetened beverages.

Jaimon T. Kelly, PhD, of Bond University in Australia, and collaborators, analyzed 18 studies that included a total of 630,108 healthy adults followed for a mean 10.4 years. Their meta-analysis of low to moderate grade studies found that a healthy dietary pattern was associated with a 30% lower incidence of CKD and a 23% lower incidence of albuminuria, according to results published in the Clinical Journal of the American Society of Nephrology.

The dietary patterns that were most frequently studied included the Mediterranean diet, DASH (Dietary Approaches to Stop Hypertension) diet, and US dietary guidelines.

Ramen Linked to Higher Fatal Stroke Risk in Japan

I rarely eat ramen, but understand it’s fairly popular among young adults in the U.S, particularly among college students because it’s cheap, quick, and tasty.

Click for details of the study in Nutrition Journal. Some background from the article:

Ramen is one of the most popular foods in Japan, despite being of Chinese origin [11]. Since its original introduction in Japan, ramen has been adapted and now consists of wheat noodles served in broth topped with sliced pork, seaweed, or menma (a Japanese condiment made from lacto-fermented bamboo shoots; Additional file 1). Being tasty and inexpensive, ramen became a popular food that was available from street food stands in Japan after World War ΙΙ. Although the number of ramen stands has decreased markedly, ramen remains highly popular in Japan. High dietary sodium content was recently reported to be a risk factor for stroke [12]; ramen has a high sodium content. However, the relationship between stroke and ramen consumption remains unclear. In this study, we investigated the association between the number of ramen restaurants in each Japanese prefecture and stroke mortality in that prefecture.

The Jerusalem Post: Has The Mediterranean Diet Gone Keto-Crazy? 

Olive oil is a prominent component of the Mediterranean diet

The Jerusalem Post has an article comparing and combining the Mediterranean and ketogenic diets:

Why choose a favorite when you can have both? Instead of making the tough Keto vs Mediterranean diet decision, many people have instead decided to combine the most appealing parts of the two diets to create a new option called the Keto Mediterranean Diet (KMD). Macronutrients are divided as follows:

• 7-10% carbs

• 55-65% fat

• 22-30% protein

• 5-10% alcohol

What is The Keto Mediterranean Diet Food List?

• Fats – olive oil, coconut oil and avocados

• Proteins – fish, cheese, eggs and lean meats • Vegetables – non-starchy varieties

• Red wine – moderate amount

• No sugars, starches, grains allowed

Carbs are limited, the way they are with the Keto diet and red wine is allowed, like in the Mediterranean diet. For people who want keto results and still enjoy going out at night for a drink, this seems like a good compromise!

Keto Mediterranean Diet Pros and Cons

Pros:

• Benefits of the Keto diet while still enjoying a glass of red wine

• More flexibility in food choices

• Healthy option  for diabetes sufferers

• Lower risk of experiencing keto-flu symptomsCons:

• Constant checking to make sure you are still in ketosis

• No strong boundaries which could weaken the results you experience

“Sweat Pea, let’s schedule a check-up with Dr. Gupta.”

From UPI:

Married men in 2017 had an age-adjusted death rate of 943 per 100,000, compared to 2,239 for widowers. The death rate was 1,735 per 100,000 for lifelong bachelors and 1,773 for divorced men.

Married women had a death rate of 569 per 100,000, two-and-a-half times lower than the 1,482 rate for widows. The death rate was 1,096 for divorcees and 1,166 for never-married women.

*  *  *

While the death rate for married men and women declined by the same 7 percent, women’s overall death rate was much lower.

But the death rates among men in all other marital categories remained essentially the same between 2010 and 2017, researchers found.

On the other hand, the death rate for widowed women rose 5 percent, while the rate for never-married women declined by 3 percent and remained stable for divorced women.
