5 surprising benefits of #walking: Any physical activity is a boon to your overall health. But walking in particular comes with a host of benefits. https://bit.ly/3uyNvhI #HarvardHealth

The next time you have a check-up, don’t be surprised if your doctor hands you a prescription to walk. Yes, this simple activity that you’ve been doing since you were about a year old is now being touted as “the closest thing we have to a wonder drug,” in the words of Dr. Thomas Frieden, former director of the Centers for Disease Control and Prevention.

Of course, you probably know that any physical activity, including walking, is a boon to your overall health. But walking in particular comes with a host of benefits. Here’s a list of five that may surprise you.

1. It counteracts the effects of weight-promoting genes. Harvard researchers looked at 32 obesity-promoting genes in over 12,000 people to determine how much these genes actually contribute to body weight. They then discovered that, among the study participants who walked briskly for about an hour a day, the effects of those genes were cut in half.

2. It helps tame a sweet tooth. A pair of studies from the University of Exeter found that a 15-minute walk can curb cravings for chocolate and even reduce the amount of chocolate you eat in stressful situations. And the latest research confirms that walking can reduce cravings and intake of a variety of sugary snacks.

3. It reduces the risk of developing breast cancer. Researchers already know that any kind of physical activity blunts the risk of breast cancer. But an American Cancer Society study that zeroed in on walking found that women who walked seven or more hours a week had a 14% lower risk of breast cancer than those who walked three hours or fewer per week. And walking provided this protection even for the women with breast cancer risk factors, such as being overweight or using supplemental hormones.

4. It eases joint pain. Several studies have found that walking reduces arthritis-related pain, and that walking five to six miles a week can even prevent arthritis from forming in the first place. Walking protects the joints — especially the knees and hips, which are most susceptible to osteoarthritis — by lubricating them and strengthening the muscles that support them.

5. It boosts immune function. Walking can help protect you during cold and flu season. A study of over 1,000 men and women found that those who walked at least 20 minutes a day, at least 5 days a week, had 43% fewer sick days than those who exercised once a week or less. And if they did get sick, it was for a shorter duration, and their symptoms were milder.

“Eat your broccoli,” may be a familiar refrain from your childhood. Maybe you didn’t love broccoli as a kid, but your parents were onto something. The “little trees” are full of fiber, folate, vitamins and more. Beth Czerwony, RD, LD. @ClevelandClinic

“Eat your broccoli,” may be a familiar refrain from your childhood. Maybe you didn’t love broccoli as a kid, but your parents were onto something. The “little trees” are full of fiber, folate, vitamins and more.

Broccoli is a member of the Brassica genus of plants, also known as the cabbage family. Broccoli’s relatives include Brussels sprouts, cabbage, cauliflower, chard and watercress. Many Brassicas have strong flavors and mix well with meats and other vegetables.

“A pile of steamed broccoli doesn’t appeal to everyone,” recognizes registered dietitian Beth Czerwony, RD, LD. “But broccoli is incredibly versatile and can be used in so many different dishes. Toss it in with your stir fry, chop it fresh in a salad or roast it with your baby potatoes. And with an abundance of nutrients, there are many benefits of eating broccoli.”

Broccoli benefits

It’s worth finding ways to add broccoli to your diet because it’s a health-boosting dynamo. Here’s some motivation for you to get your green on: Some of the beneficial substances in broccoli are somewhat unique to the Brassica family of vegetables. Broccoli provides nutrients that may:

  • Reduce your risk of cancer.
  • Help control blood sugar.
  • Protect your gut.
  • Boost immunity.

As a superfood status, broccoli can improve your health with these five components:

1. Compounds to reduce cancer risk

“Broccoli offers some powerful molecules that protect your cells from damage,” says Czerwony. “Some of them even destroy cancer cells.”

Cancer-fighting molecules in broccoli include DIM, indole-3-carbinol and sulforaphaneAccording to studies, they may help:

  • Detoxify certain substances that promote the growth of cancer cells, which means they don’t remove the substances, but they remove the harmful effects.
  • Provide antioxidants, which prevent cell damage that can lead to cancer.
  • Stop the growth and spread of cancer cells.
  • Support apoptosis, your body’s process for destroying cells that could turn into cancer.

These anticancer molecules are in several of broccoli’s cruciferous veggie relatives, too. These nutrients don’t survive cooking or freezing. So, to get the benefits, raw broccoli is best.

“Some of these compounds are even more concentrated in broccoli sprouts,” notes Czerwony. “You can find broccoli sprouts in health food stores and many grocery stores. Sprouts are also easy to grow at home using a sprouting kit.”

2. Nutrients to help manage blood sugar

Both human and lab studies suggest compounds in broccoli may help lower blood sugar in people with Type 2 diabetes. This effect may be due to the antioxidants in broccoli, like vitamin C.

Research shows that fiber can also help with blood sugar management. At 2.5 grams of fiber per cup, broccoli is a good source of this nutrient.

3. Ligands to protect your gut

In a nonhuman study, researchers found that broccoli can help protect the lining of your small intestine. Compounds found in broccoli, called aryl hydrocarbon receptor ligands, help keep small intestine cells working well.

Why do those cells matter so much? When your small intestine lining is healthy, it only allows water and nutrients to pass through it into your bloodstream.

But when the cells of the lining are damaged, undigested food particles, bacteria and other disease-causing particles may pass through. A damaged small intestine lining can lead to infections and inflammation. It can also prevent you from absorbing the nutrients you need.

4. Vitamin C to boost immunity

Vitamin C is well-studied as an immune-boosting nutrient. When you don’t have enough vitamin C, you’re more likely to get infections.

The antioxidant effects of vitamin C also help your body keep free radicals under control. “Free radical damage is linked to all kinds of problems, including Alzheimer’s disease, autoimmune diseases, cancer, heart disease and Parkinson’s disease,” says Czerwony. When you don’t have enough antioxidants to neutralize free radicals, they damage your cells.

Surprising but true: Broccoli has more vitamin C than oranges. In 1 cup of the green cruciferous veggie, you get a whopping 81 milligrams of vitamin C. That’s 90% of the daily U.S. recommended dietary allowance (RDA) for adults. (An orange has about 70 milligrams.)

5. Nutrients to help heart health

Research suggests certain bioactive compounds in broccoli may boost your heart health in a variety of ways. It may:

  • Lower triglycerides and LDL (“bad”) cholesterol: “High LDL can lead to fatty deposits on your artery walls, increasing your risk of artery disease, stroke and heart attack,” Czerwony explains. Research shows that eating broccoli can lower triglycerides, a type of fat, as well as LDL.
  • Provide fiber: According to a review of 22 clinical trials, fiber can reduce your risk of cardiovascular and coronary artery disease.
  • Reduce calcium buildup in blood vessels: When calcium builds up on your blood vessel walls, it increases your risk of heart attack and strokeAccording to research, broccoli can help reduce this calcium buildup.

Is frozen broccoli healthy?

“If you want those anticancer compounds like sulforaphane, choose fresh broccoli,” advises Czerwony. Freezing inactivates sulforaphane.

“Frozen broccoli also loses a bit of its vitamin content. But overall, frozen broccoli is still very healthy. It’s better than not eating any broccoli because you still get a lot of the health benefits,” she continues.

The relationship between alcohol consumption and menstrual cycle: a review of the literature:

Abstract

Alcohol use affects men and women differently, with women being more affected by the health effects of alcohol use (NIAAA, 2011). Yet, a dearth of information investigating the alcohol use in women exists (SAMSHA, 2011). In particular, one dispositional factor hypothesized to contribute to alcohol consumption in women is the menstrual cycle. However, only 13 empirical papers have considered the menstrual cycle as related to alcohol consumption in women. These studies fall out with somewhat mixed findings suggesting that the premenstrual week is associated with increased, decreased, or no change in alcohol consumption, likely due to methodological differences in menstrual cycle determination and measures of alcohol consumption. These methodological differences and possible other contributing factors are discussed here with recommendations for future research in this area. Understanding the contribution of the menstrual cycle to alcohol consumption is one step in addressing an important women’s health concern.
