Inflammation can be a beneficial sign that the body's immune system is fighting an infection, but it can also linger over time, damaging the body. There is evidence that eating a diet heavy in foods that promote inflammation can increase the risk for certain health problems, and also that a healthy diet can reduce inflammation.

Bleeding gums are a sign of gingivitis, an early stage of periodontal disease, but they may also signal low vitamin C in your diet, suggests a study published online Feb. 1, 2021, by Nutrition Reviews. Researchers examined 15 published studies involving 1,140 healthy people as well as data on 8,210 people from the CDC's Health and Nutrition Examination Survey. They found that low vitamin C levels in the bloodstream were associated with an increased risk for gum bleeding with gentle probing. The researchers also observed that increasing vitamin C intake may help resolve the problem.

Increased bleeding in general is one of the symptoms of scurvy, a disease caused by severe vitamin C deficiency. Scurvy, which often affected 18th-century sailors without access to fruits and vegetables, is rare today. Still, this new study sheds light on a potential cause of gum bleeding related to vitamin C levels that are only slightly low — not enough to cause scurvy.

The Chinese gooseberry — more commonly known as kiwifruit or simply kiwi — is a brown, fuzzy, egg-sized fruit with bright green flesh. You can sometimes find gold kiwis, which have yellow flesh, or kiwi berries, which are the size of a grape and have smooth, green skin. Sweet yet slightly tart, kiwi's flavor has been described as a cross between a strawberry and a banana with a hint of citrus.

One kiwi provides nearly all (about 80%) of an adult's daily vitamin C requirement. It's also a good source of fiber, potassium, and vitamin K.

Whether you're an exercise novice or a gym regular, these tips can help you get the most out of your workout.

When it comes to exercise, timing is everything — but not in the way we normally think about timing. What matters most is making the time to exercise regularly, not when it happens. That said, your personal experience and specific goals may influence what workout schedule works best for you.

"If you're just starting a physical activity routine, any time that you feel motivated and energized enough to exercise is the best time for you," says Dr. Beth Frates, clinical assistant professor of physical medicine and rehabilitation at Harvard Medical School. For some people, that's in the morning; for others, the afternoon works better. But if you can work out with a friend, choose a time that works best for both of you, she suggests. Teaming up with an exercise buddy is more enjoyable, and you can hold each other accountable.

You have the power to reduce certain risk factors for the disease.

We've come a long way in our understanding and treatment of age-related macular degeneration (AMD), the leading cause of vision loss for people ages 50 or older in the United States. We've learned that certain genes and lifestyle factors increase the risk for developing AMD, and discovered treatments that often slow the disease's progression.

Yet for all our advances, we still don't have a guaranteed way to prevent AMD. You are at greater risk if one of your parents had the condition. "One needs to be concerned, but it doesn't mean you're destined to get it. It's a complex disease, and it takes a combination of factors for it to develop," says Dr. Joan W. Miller, chief of ophthalmology at Harvard-affiliated ­Massachusetts Eye and Ear and ophthal­mology chair at Harvard Medical School.

It takes a one-two punch to lower these risks for heart disease, heart attack, and stroke.

High cholesterol has long been known as a bad actor in heart health. Too much LDL (bad) cholesterol in your blood can lead to fatty deposits in your arteries and the formation of artery-narrowing plaque (atherosclerosis), heart attacks, and strokes.

But LDL doesn't act alone. Chronic inflammation — a persistent activation of the immune system — also fuels heart attack and stroke risks. That means you must address both high LDL levels and chronic inflammation to protect your health.
