Though people are living longer, the proportion of years spent in good health remains the same. Recent research has shown that dietary flavonoids delay biological aging (J Transl Med. 2023;21(1):492). A massive new study has added to the evidence that flavonoids help people to age more healthily. People with the most flavonoids in their diet had 15% lower risk of developing frailty, 12% lower risk of developing impaired physical function and 12% lower risk of developing poor

Can resveratrol improve cholesterol? It can if you take enough, as this new study found out. Resveratrol is a polyphenol similar to flavonoids. It is found primarily in the skin of grapes and mulberries as well as in dark chocolate, raspberries, blueberries and peanuts. Resveratrol in supplements usually comes from the herb Japanese knotweed. This meta-analysis of 17 controlled studies, which included 968 people, found that resveratrol significantly reduces total cholesterol,

Despite all the research on the myriad benefits of flaxseeds, this study is the first meta-analysis of flaxseed’s effects on prediabetics and type 2 diabetics. What did it find? Flaxseeds are loaded in fiber and omega-3 fatty acids, both of which could help diabetics. This meta-analysis of 7 controlled studies put the powerful seed to the test. The studies used 13-40 grams a day of ground flaxseed, and most of the studies lasted 12 weeks. The results showed that flaxseed sign

95% of women undergoing radiation for breast cancer experience radiation induced dermatitis. A new 5 week double-blind, placebo-controlled study has found that a 2% curcumin gel significantly reduces redness and irritation. The curcumin gel also significantly reduced pain in the 2nd, 3rd, and 4th weeks. Cancer Invest. 2025 Mar ;43(3):173-182

Pneumonia is a leading cause of hospitalization and death, and the challenge gets bigger as you get older. New research suggests that many of those deaths can be prevented by just getting enough vitamin D. Community-acquired pneumonia can be caused by bacteria, viruses and fungi. The leading bacterial causes are S pneumoniae and H influenzae. Some of the leading viral causes are rhinovirus, influenza and COVID. It is a very common concern that increases with age.

The science is quickly building supporting the use of saw palmetto berry extract to reduce hair loss and enhance hair growth in both men and women. This new study adds to the growing evidence. Though often thought of as a male problem, thinning hair is a big problem for women too. 80% of men will experience male pattern hair loss by the age of 80; 40% of women will experience female pattern hair loss by the age of 50. This new study included 30 men and 30 women. They were all

A new double-blind study of 98 people with mild-to-moderate osteoarthritis found that boswellia extract (30% 3-acetyl-11-keto-β-boswellic acid ) at a dose of 300- 600mg a day significantly improves scores of pain, stiffness and physical function on the WOMAC Arthritis Index, walking distance and quality of life. But that’s not all it does. Remarkably, boswellia even improved joint space in the knee in 44.1% of the 600mg group, suggesting that boswellia can actually help rever

This new study shows that a combination of two herbs that are traditionally used for skin increases collagen and hydration and improves skin elasticity, pores and wrinkles. The study included 150 men and women over the age of 20. 30% of them were between 20 and 40, and 70% of them were over 40. The herbs being studied were astragalus and gotu kola in equal combination. One group used the herbs topically twice a day for 4 weeks, one group used the herbs orally twice a day for

Diabetic nephropathy is the leading cause of end-stage kidney failure in the world. High blood sugar leads to oxidative stress, which plays a key role in nephropathy. One natural antioxidant can really help. In this new study, 100 people with type 1 diabetes added either nothing or 300mg a day of alpha-lipoic acid to their conventional medication for 3 months. The study found that people with type 1 diabetes have significantly higher levels of oxidative stress and significant

Around 38 million people around the world are living with HIV. Around 650,000 die every year. Despite antiretroviral therapy, many people still have suppressed immunity, low platelets, malnutrition and low body mass index. Progress has been made, but more help is needed. Meet moringa. Moringa oleifera is common in the Middle East, Africa and Asia. It is loaded in nutrients and has been found to improve immunity and nutritional status. This systematic review and meta-analysis

A research abstract (Abstract 4382525) presented at the 2025 American Heart Association Scientific Sessions has revealed for the first time how much getting just enough vitamin D can help prevent a heart attack. The study included 630 people with acute coronary syndrome who had had a previous heart attack. Each person in the activ

This massive study of 12,666 women who were 65 or older and 8,776 men who were 60 or older found that taking a multivitamin slowed cognitive aging by about 60%, which translated to about 1.8 years over the 3 year study. It found that, compared to a placebo, taking a multivitamin improved memory by the equivalent of 3.1 years. The study also found that taking a multivitamin for 2 years can slow biological aging by a significant 10-20%. Cocoa Supplement Multivitamins Outcomes S

Fibromyalgia is a common, but still too little discussed, condition characterized by chronic, widespread musculoskeletal pain, sleep problems, fatigue, mental distress and cognitive impairment. This new study suggests a safe, natural solution that might help. Fibromyalgia affects between 2% and 8% of all people and probably about 2%- 3% of people in the United States and Canada. For some reason, fibromyalgia favours women: in adults, women are twice as likely to have fibromya

High levels of uric acid can lead to all kinds of problems. The evidence is mounting that cherries can help. Having too much uric acid can lead to painful gout. Less known is that, even in the absence of gout, it can cause systemic inflammation, high blood pressure, hypothyroidism and chronic kidney disease. Tart cherries have been shown in a number of studies to reduce uric acid and improve suffering from gout (Arthritis Rheum 2013;65:1135-6; Arthritis Rheum 2012;64:4004-11)

People with type 2 diabetes have insulin resistance, pancreatic β-cell dysfunction, and elevated blood glucose. Taking probiotics may help improve all three, according to a new study. Recently, surprising research has suggested that, by modulating gut bacteria, probiotics can help regulate blood sugar and modulate type 2 diabetes. This new double-blind study gave 42 type 2 diabetics who were on the drug metformin either a placebo or a Bifidobacterium probiotic for 6 weeks. Th

A recent study found that people who use melatonin are more likely to diagnosed with heart problems. The media was all over the bad news, but they neglected to tell their readers about the limitations and design flaws of the study. The study, which was presented at the 2025 American Heart Association Scientific Sessions, concluded that people who had used melatonin for more than a year were 90% more likely to be diagnosed with heart failure (4.6% versus 2.7%) over a 5 year pe

Peanuts get a lot of bad press. Here’s some really good press. Eating peanuts improves your memory, and now we might know why. A new single-blind, controlled study has shown that eating 60g a day of unsalted, roasted peanuts with the skin for 8 weeks significantly improved verbal memory in healthy adults whose average age was 67 years. And the improvement was significant: delayed recall improved by 5.8%. This is not the first time peanuts have been shown to improve memory. A
