Health Benefits of Resveratrol

Resveratrol is a potent antioxidant,  having anti-inflammatory, immunomodulatory, glucose and lipid regulatory, neuroprotective, and cardiovascular protective effects, therefore, can protect against diverse chronic diseases, such as cardiovascular diseases (CVDs), cancer, liver diseases, obesity, diabetes, Alzheimer’s disease, and Parkinson’s disease. 

Antioxidative Activities

Resveratrol has shown strong antioxidant properties in many studies. Resveratrol protects against oxidative stress, one of the primary contributors to many diseases.

Anti-Inflammatory Activities

Resveratrol has been illustrated to have potent anti-inflammatory activities in many studies. Resveratrol protected from inflammation not only by inhibiting the production of pro-inflammatory cytokines such as tumor necrosis factor α (TNF-α) and interleukin-1β (IL-1β), but also by inducing anti-inflammatory heme oxygenase-1 (HO-1) in RAW264.7 macrophages.

Immunomodulating Effects

Resveratrol has exerted immunomodulating effects in various studies. Resveratrol modulates immune response against pathogens like viruses, bacteria, and some toxic materials. In short, resveratrol could modulate both cellular and humoral immunity to reduce replication and the viability of pathogens, and bidirectionally regulate the related cytokine/chemokine production through the canonical immune response pathways.

Cardiovascular Diseases

Resveratrol has been reported to protect against CVDs in certain research. Resveratrol prevented the pathological progression of hypertension, a major risk factor of CVDs, through Nrf2 activation, owing to its antioxidant and anti-inflammatory capacity.

Cancers

Resveratrol has shown its anticancer bioactivities by impairing glycolysis, inhibiting cancer cell growth and proliferation, inducing apoptosis, promoting antitumor immune responses, and preventing adhesion, migration and invasion of cancer cells by modulating related molecules and gene expression through various signaling pathways. 

Liver Diseases

Resveratrol has shown its protective impacts on several liver diseases in some studies. Specifically, resveratrol alleviated non-alcoholic fatty liver disease (NAFLD). Besides NAFLD,  resveratrol could improve chemical-induced liver injuries, fibrosis, and cirrhosis by modulating redox status, regulating lipid metabolism, ameliorating inflammation, and inducing autophagy with various cytokines, chemokines, and transcription factors involved.

Diabetes

Many studies have shown that resveratrol could effectively regulate glucose metabolism, improve insulin resistance, improve diabetic complications, and restore the function of multiple systems via modulating SIRT1/NF-κB/AMPK signaling pathways and some associated molecules like NALP3 inflammasome, as well as the expressions of relevant genes.

Obesity

Resveratrol also showed positive impacts on obesity-related complications, such as reproductive dysfunction like infertility and endocrine disorders. Moreover, resveratrol has shown to decrease body weight, regulate lipid deposition, modulate adipocyte gene expression, and promote white adipose browning.

Alzheimer’s Disease and Parkinson’s Disease

Alzheimer’s disease and Parkinson’s disease are neurodegenerative disorders, seriously decreasing life quality, many studies have shown that  resveratrol may have the potential to improve these diseases. 

Food Sources of Resveratrol

Resveratrol occurs naturally in some plant foods. You can add resveratrol to your diet by eating foods like peanuts, grapes, blueberries, raspberries, and mulberries. Red wine is also a good source of resveratrol. You can also take resveratrol in supplement form.

Six Key Food Groups that Are Healthy for Your Heart

Researchers investigated the impact of different food groups on cardiovascular health. They found that diets rich in fruits, vegetables, legumes, nuts, whole-fat dairy, and fish were linked to lower cardiovascular risk. Further studies are needed to understand how much each component contributes to overall risk reduction. Unhealthy diets are a major risk factor for cardiovascular disease (CVD). In particular, higher amounts of processed meats, refined grains, and sugar-sweetened beverages are known to increase cardiovascular risk.  Concurrently, diets such as the Dietary Approaches to Stop Hypertension (DASH) diet, Mediterranean and Healthy Eating Index (HEI) are linked to lower CVD risk. These diets all include increased consumption of: Fruit Vegetables Legumes Nuts Fish However, recent studies, have shown that some foods—such as whole-fat dairy—previously thought to increase CVD risk may have neutral or beneficial effects. However, many of these new findings have yet to be incor...

Nutrients that Prevent Telomere Shortening

Image
Telomerase is an enzyme that helps maintain telomeres , the protective tips of chromosomes. As we age, our telomeres naturally shorten, contributing to the aging process. Telomerase supplements are designed to promote the lengthening of telomeres, which may help prevent some age-related diseases and improve overall health. What are telomeres?  Telomeres are stretches of DNA at the end of chromosomes that protect the end from deterioration. They shorten each time a cell divides, and when they get too short, cells can no longer divide and die off or become cancerous. Telomere length is a good biological marker of aging, and shorter telomeres usually indicate greater age and a higher likelihood of age-related pathologies. As telomeres provide protection for the genetic material inside DNA, shorter telomeres provide less protection. The shorter the telomere, the more likely a subject is to suffer from disease or age-related illnesses.  What is telomerase?  Telomerase ...
