New research upholds the longstanding advice to eat five fruits and vegetables a day: https://bit.ly/2TRkwbR #HarvardHealth


Here’s a medical news story that combines a common habit (drinking coffee) with a common skin condition (rosacea) — and it even has a happy ending.
Rosacea is probably something you’ve seen plenty of times and didn’t know what it was — or perhaps you have it yourself. It’s that pink or red discoloration on the cheeks some people have, especially fair-haired women. Sometimes there are small bumps that may look a bit like acne. If you look closely (after asking nicely for permission, of course), you’ll see tiny blood vessels just under the surface of the skin. In more severe cases it may involve the chin, forehead, nose, ears, and other skin surfaces. It may affect the eyes, eyelids, and cause thickening of the skin over the nose.
We don’t know what causes rosacea. However, there are theories that it may be, at least in part, a genetic condition, as it can run in families. Because the immune system seems to be involved in the inflammation of rosacea, and because other autoimmune conditions (such as type 1 diabetes and multiple sclerosis) may accompany rosacea, abnormal immune function may play a role. Medications (such as topical anti-inflammatory drugs) and antibiotics can reduce redness and inflammation but there is no cure. Many people seem to be able to reduce signs of rosacea by modifying their diet to avoid foods that trigger it.
Rosacea affects more than 14 million people in the US, including some celebrities, such as Bill Clinton and the late Diana, Princess of Wales. And while it’s not dangerous, it can have a significant cosmetic impact. Caffeine, sun exposure, spicy foods, and hormonal factors are thought to be able to trigger rosacea’s development or make it worse once present. Yet, a new study challenges the connection between caffeine and rosacea.
A recent study analyzed health data from surveys provided to nearly 83,000 women over more than a decade and found that:
These results of this study are more than just interesting observations. If other research can confirm the findings, it could lead to a better understanding of why rosacea develops in some people and not in others. Because inflammation driven by the immune system is thought to play an important role in rosacea, insights into the development of this disease could extend to advances in other autoimmune disorders. Finally, many people with rosacea (or a family history of the disease) who like coffee may avoid it because of the widespread notion that coffee will make it worse. The findings of this study suggest that’s not true.
As with all research of this type, there are limitations to consider. For example, this study
Coffee is one of the mostly widely consumed beverages on the planet, and it’s also among the most widely studied. While it can cause problems for some people (such as heartburn, tremor, or palpitations), it’s a source of pleasure and enjoyment for millions. In addition, coffee has been linked with a number of health benefits, ranging from reductions in type 2 diabetes and liver cancer to greater longevity. From this latest research, it appears that you can add the possible prevention of rosacea to the list.

Protein in Greek yogurt: Greek yogurt is a protein powerhouse. It has almost twice the protein of traditional yogurts and provides the same gut-friendly bacteria. #HarvardHealth

Tropical fruits are those native to warm, tropical climates and include everyday favorites such as bananas and oranges. Here, we’re highlighting a few slightly more exotic choices that deserve a place on your shopping list at least once in a while. Try these suggestions when you’re craving something sweet for a snack or after dinner.

Pineapple. Sure, canned pineapple is convenient, but the flavor of a fresh pineapple is far more vibrant. Try pineapple chunks tossed with chopped fresh mint.

Mango. The pale orange, creamy flesh of ripe mango has a sweet, slightly spicy or pine-like flavor, according to some people. To serve, slice the mango close to the pit, then score the flesh crosswise, as shown above. If you like spicy food, sprinkle with a little chili powder.

Papaya. These large, pear-shaped fruits have reddish-orange flesh with a flavor akin to a melon with a faint floral quality. If you like, you can eat the black seeds, which have a peppery bite. Scoop the flesh out with a melon baller or spoon. A squeeze of fresh lime juice helps temper the sweetness.

Everyone likes a bargain, and lap swimming is a good deal when it comes to exercise. Swimming is a remarkably effective workout because it combines three important types of exercise in one: aerobics, stretching, and strengthening. “Simply keeping yourself afloat activates the core muscles in your back and abdomen. And you have to move all of your muscles to swim,” says Leigh de Chaves, a physical therapist and clinical supervisor of rehabilitation services at Harvard-affiliated Brigham and Women’s Hospital. (She also swam competitively in college.)
Consider lap swimming if you’re generally healthy, you’re a good swimmer, and your doctor says it’s okay. It’s no problem if you’re not a fan of the crawl: “Any stroke is fine. The breast, side, and back strokes are often favored because a lot of people don’t like putting their face in the water, like you have to do with the crawl,” de Chaves says.
However, lap swimming might be not be doable if you have an underlying condition, such as heart disease or a seizure disorder, that puts you at risk for a life-threatening event in the water. You may also need to skip lap swimming if you’re not strong enough to climb in and out of the pool easily. And you should be careful if you have injuries to your shoulders or neck. Lap swimming may increase your pain.
A green light for a lap swimming routine doesn’t mean you should start with 20 laps. Ease into it. “Focus on the amount of time you spend swimming, at first. For example, swim for five or 10 minutes, a few times per week. Gradually increase the amount of time each week, and note how many laps you can do within that time. Eventually, set goals to increase your speed by doing more laps in your set time, so that you can measure your progress,” de Chaves explains.
Once you’re in the swim of things, you’ll notice lots of benefits to lap swimming. It’s easy on the joints, thanks to buoyancy in water, and it has a meditative quality that forces you to focus on your movement and breathing.
Lap swimming also
De Chaves points out that it’s important to warm up your muscles before diving into a lap swimming workout. All it takes is a few minutes of gentle paddling, and then static stretches of your shoulder and leg muscles.
Some other dos and don’ts:
If you’re not a lap swimmer, you can still benefit from aquatic exercises — exercising in the shallow end of a pool. You might take a class with a trainer who leads a group through a set of exercises with special water weights or flotation devices (like a pool noodle). Or you can simply try water walking; working against the resistance of the water is good for your muscles and bones.
“If you have balance problems, it’s a good idea to exercise with a friend who can assist you. I also recommend wearing a buoyancy belt around your waist to keep you upright,” de Chaves advises.
Look for aquatic exercise classes — such as strengthening or aerobics — at the local YMCA, a fitness center, or a community center.

A modest uptick in the amount of fruit and vegetables you eat can help ward off type 2 diabetes, according to a study published online July 8, 2020, by The BMJ. From a much larger study involving some 340,000 people from eight European countries, scientists selected 9,754 participants who were newly diagnosed with diabetes over a decade. Researchers compared the fruit and vegetable intakes of these people to those of about 13,000 participants who remained diabetes-free during the study period. Researchers also measured blood levels of seven key plant-derived nutrients, including vitamin C and brightly colored antioxidant pigments called carotenoids. People with the highest intakes of fruit and vegetables and the highest blood levels of the plant-derived nutrients were 25% to 50% less likely to get diabetes during the study period, compared with those who ate the least of these food groups or had the lowest nutrient levels. Even better, it didn’t take a whole lot of extra green, red, yellow, and orange on the plate to make a dent in diabetes risk. The equivalent of only two-thirds of a medium apple or just over one-third of a cup of mixed fruit each day offered protection.
