<h2><strong>Top 5 health benefits </strong>of grapefruit</h2>
<h3><strong>1. Rich in antioxidants</strong></h3>
<p>Grapefruit provides a number of beneficial, protective nutrients and plant compounds that have <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3614697/" target="_blank" rel="noopener"><u>antioxidant properties</u></a>. This means they help protect cells from the potential damage caused by unstable molecules, called free radicals.</p>
<p>In particular, they’re a good source of beta-carotene, which is converted in the body to <a href="https://www.nhs.uk/Conditions/vitamins-minerals/Pages/Vitamin-A.aspx" target="_blank" rel="noopener">vitamin A</a>, and is thought to reduce the risk of chronic conditions, including <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3942711/" target="_blank" rel="noopener"><u>macular degeneration</u></a>. Grapefruit is also a useful source of <a href="https://pubmed.ncbi.nlm.nih.gov/20394143/" target="_blank" rel="noopener"><u>lycopene</u></a>, which is associated with a reduced risk of cancer.</p>
<h3>2. May support heart health</h3>
<p>In 2012, the American Heart Association published a report that suggested that a diet high in certain <a href="https://pubmed.ncbi.nlm.nih.gov/22574825/" target="_blank" rel="noopener"><u>flavonoids</u></a> – compounds found in citrus fruits, including grapefruit – may <a href="https://www.sciencedaily.com/releases/2012/02/120223182638.htm" target="_blank" rel="noopener">lower a woman’s risk of stroke</a>. However, more research is needed to understand exactly why this is.</p>
<p>Grapefruit is rich in potassium and fibre, as well as protective antioxidants that may help manage blood pressure and cholesterol levels. Human studies have demonstrated the beneficial role grapefruit, and specifically red grapefruit, may play a part in helping <a href="https://www.ncbi.nlm.nih.gov/pubmed/16506849" target="_blank" rel="noopener">improve cholesterol levels</a>, particularly in those suffering with <a href="https://www.bhf.org.uk/informationsupport/conditions/atherosclerosis" target="_blank" rel="noopener">atherosclerosis</a>.</p>
<h3><strong>3. May help with weight loss </strong></h3>
<p>While low in calories and high in fibre, eating grapefruit is unlikely to deliver the dramatic weight loss touted in some fad diets; however, there is some evidence to suggest that consuming grapefruit may be of some assistance. A 12-week Japanese study looked at the effects of grapefruit versus a placebo, and there was a significant <a href="https://www.ncbi.nlm.nih.gov/pubmed/16579728" target="_blank" rel="noopener">reduction in weight</a>, as well as blood glucose levels, in those participants who consumed half a grapefruit before meals.</p>
<h3><strong>4. May aid blood sugar management</strong></h3>
<p>Animal studies have examined the beneficial role grapefruit juice may play in reducing blood glucose levels and <a href="https://www.ncbi.nlm.nih.gov/pubmed/25296035" target="_blank" rel="noopener">improving insulin resistance</a>. This is further supported by a higher fruit and green vegetable intake being associated with a significantly <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4225228/" target="_blank" rel="noopener"><u>reduced risk of type-2 diabetes</u></a>.</p>
<h3>5. May promote better brain function</h3>
<p>There is some promising research into the role of <a href="https://www.frontiersin.org/articles/10.3389/fnins.2021.640648/full" target="_blank" rel="noopener"><u>flavonoids</u></a> in the diet and <a href="https://www.ncbi.nlm.nih.gov/pubmed/20955649" target="_blank" rel="noopener">improvements in memory and cognition</a>, as well as the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2775888/" target="_blank" rel="noopener">prevention of neurodegenerative conditions</a>. However, it is too early to say whether grapefruit in particular has a significant impact on brain health.</p>
<h2>Can grapefruit affect prescription medications?</h2>
<p>The <a href="https://www.nhs.uk/chq/pages/2474.aspx" target="_blank" rel="noopener noreferrer">NHS advises</a> that fresh grapefruit or grapefruit juice should not be consumed with certain medications, as it has been shown to reduce their breakdown and elimination, which can result in increased blood levels of the drug. These include, but are not limited to: statins, calcium channel blockers, immunosuppressants, certain cancer medications and Entocort, which is used to treat Crohn’s disease. Always check with your GP if you’re taking a prescription medication before consuming grapefruit or grapefruit juice.</p>
<p>Read more from the NHS about <a href="https://www.nhs.uk/chq/pages/2474.aspx" target="_blank" rel="noopener noreferrer">how grapefruit can affect medicine</a>.</p>
<h2>Overall, is grapefruit good for you?</h2>
<p>A fruit well worth incorporating into your diet, grapefruit contains immune-boosting vitamin C, antioxidants to protect against cell damage, vitamin A-stimulating beta-carotene, and lycopene, which is associated with a reduced risk of cancer. There is also some evidence to suggest that consuming half a grapefruit before meals could help with weight loss, plus it could help to reduce blood glucose levels and improve insulin resistance.</p>
