WEIGHT & ERECTILE DYSFUNCTION AUTHOR: D R. M A R YA M YAVA R I , M D, P H. D. , N D NMT150 2023 LEARNING OBJECTIVES Considerations for providing nutritional guidance as it relates to this week’s case presentation: Diet Reduce Alcohol and smoking L arginine Life Style TREATMENT GOALS Address presenting symptoms and improve patient comfort Support full and speedy recovery to return to regular activities Patient education Monitor and Prevent sequelae  VASCULAR HEALTH T2DM incidence in the US has increased. This increase is associated with sedentary lifestyle, obesity, and an aging population. Obesity is a major risk factor for ED in diabetics, with a prevalence of 32.2% in the US. Testosterone deficiency and Metabolic syndrome are strongly associated. https://www.sciencedirect.com/science/article/abs/pii/S1743609515310031  VASCULAR HEALTH Erectile dysfunction (ED) is common in patients with cardiovascular disease (CVD). ED affects quality of life and is an independent risk factor for future cardiovascular events. A 3-year time period between onset of ED symptoms and CVD event allows for risk mitigation. Sexual function should be included in CVD risk assessment for all men. https://academic.oup.com/eurheartj/article/34/27/2034/440049  DIET Eating a balanced diet help maintain sexual function and decrease the risk of ED. A study found that men who more strictly followed a Mediterranean diet had a reduced risk of developing ED. In particular, they consumed less red or processed meat and primarily ate: Fruits, vegetables, legumes, nuts, Fish Another study similarly found that eating more fruits, vegetables, and flavonoids lowered the risk of ED in men ages 18 to 40. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8451697/ https://www.sciencedirect.com/science/article/abs/pii/S1743609515310031  DIET & FREE RADICALS Oxidative stress is involved in arteriogenic ED, which may result from lack of perfusion, antioxidant deficiency, and waste product accumulation. Oxidative radicals contribute to impaired endothelium- dependent smooth muscle relaxation, mitochondrial injury, endothelial structural damage, and erectile tissue fibrosis in arteriogenic ED. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8451697/ https://www.sciencedirect.com/science/article/abs/pii/S1743609515310031  DIET & FREE RADICALS Antioxidant therapy can efficiently improve molecular and ultrastructural alterations in erectile tissue, but it may not have a significant effect on fibrosis and functional deficit. Long-term consumption of dietary antioxidants may improve erectile function by removing oxidative products and preserving NO bioavailability and endothelial and mitochondrial structural integrity. https://onlinelibrary.wiley.com/doi/full/10.1111/j.1365-2605.2010.01083.x https://www.foodingredientsfirst.com/news/rapid-testing-for-food-antioxidants-developed-by-researchers-in-japan.html  DIET & PAD A diet without the right balance of nutrients can contribute to the development and progression of Peripheral Artery Disease Following a heart-healthy diet is key, which involves reducing intake of saturated fats, simple sugars, fats, and trans fats, limiting sodium, and increasing fiber intake Certain diets like the Mediterranean diet and DASH diet can improve vascular health in people with PAD by increasing healthy fats, fruits and vegetables, nuts, and decreasing unhealthy fats, sodium, and sugar intake Following a healthy diet for PAD can lessen symptoms such as leg pain, numbness, or weakness and improve quality of life. https://jamanetwork.com/journals/jama/fullarticle/1817779 https://www.sciencedirect.com/science/article/abs/pii/S0021915018302922  ALCOHOL Studies have shown mixed results for the effects of alcohol on ED. Short-term consumption of alcohol can cause a temporary inability to get an erection by depressing the central nervous system, decreasing penis sensitivity, and limiting blood flow to the penis. Alcohol is a diuretic, leading to dehydration and increased levels of angiotensin, which can narrow blood vessels and limit blood flow to the penis. https://www.nature.com/articles/3901556  ALCOHOL Chronic consumption of large amounts of alcohol can damage nerves, increase the risk of cardiovascular disease, and damage blood vessels, all of which can impact erectile function. Chronic heavy alcohol users may experience dysfunction of the autonomic nervous system, with ED being a common symptom. ED is closely related to cardiovascular disease, and heavy alcohol consumption increases the risk of developing high blood pressure, which is a risk factor for sexual dysfunction. https://www.nature.com/articles/3901556  SMOKING Impotence is twice as likely to occur in smokers than non- smokers, with exposure to second-hand smoke being a significant factor. Smoking can affect the nervous system, hormones, and vascular system required for sexual functioning, leading to impotence. https://www.canada.ca/en/health-canada/services/health-concerns/tobacco/smoking-your-body/smoking-diseases/impotence-smoking.html  SMOKING Long-term smoking causes physiological damage and increases the risk of moderate or severe impotence. Quitting smoking can partially or fully recover erectile function, depending on the degree of damage inflicted and which system is affected. Heavy smokers (40+ cigarettes/day) had "softest" night-time erections, and smoking was related to an abnormal decline of blood pressure in the penis. Men who have reported losing their erections before orgasm have completely reversed this situation by quitting smoking. https://www.canada.ca/en/health-canada/services/health-concerns/tobacco/smoking-your-body/smoking-diseases/impotence-smoking.html  WEIGHT MANAGEMENT Obesity and overweight are independent risk factors of erectile dysfunction (ED). ED is significantly more common in men with obesity, who are overweight, or with a larger waist circumference. https://pubmed.ncbi.nlm.nih.gov/34644814/  WEIGHT MANAGEMENT Meta-analysis was performed to clarify the therapeutic effect of weight loss on erectile function: 5 studies with 619 participants were enrolled in the meta-analysis. It showed that weight loss can improve erectile function in overweight or obese men. Losing weight could serve as an adjuvant therapy for ED. https://pubmed.ncbi.nlm.nih.gov/34644814/  WEIGHT MANAGEMENT Being overweight is linked to erectile dysfunction (ED). Obesity lowers testosterone in men, which can affect sex drive. Extra weight can cause circulatory problems and heart disease, which can also lead to ED. Medications that treat conditions caused by extra weight can also cause ED. Stress, depression, and anxiety related to weight can also cause ED. Regular exercise can lower the risk of ED and boost mood and body image. https://www.sciencedirect.com/science/article/abs/pii/S0140673612605200 https://www.sciencedirect.com/science/article/abs/pii/S1743609515310031  L-ARGININE L-arginine is an amino acid obtained through dietary sources or produced from L-citrulline L-arginine may be more effective in patients with ED with low nitric oxide L-arginine can allow for long-duration treatment for ED. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8451697/ INDICATIONS Taking 2.5-5 grams of L-arginine daily by mouth may improve sexual function in people with ED. L-arginine, when taken with medications such as sildenafil and tadalafil, may work better than taking either L-arginine or the medication alone for ED. L-arginine by mouth may improve symptoms and exercise tolerance in people with angina but does not seem to widen narrowed blood vessels. L-arginine by mouth can reduce blood pressure in healthy people, people with high blood pressure, and people with slightly high blood pressure with or without diabetes. OTHER LIFESTYLE FACTORS Sleep Exercise Psychotherapy Stress reduction  CASE John is a 55-year-old man who presents to your naturopathic clinic with complaints of erectile dysfunction (ED) for the past year. He has no significant medical history, is not taking any medications, and denies tobacco or recreational drug use. He reports a healthy diet and moderate exercise routine.

These mechanisms include the low-energy content of DFs, their bulking effect, their ability to increase viscosity, their capacity to bind, and their potential to ferment, all of which can help alleviate hyperlipidemia symptoms. From the molecular level, DFs could possibly affect the activities of HMG-CoA reductase, LDL receptors, CYP7A1, and MAPK signaling pathway as well as other lipid metabolism-related target genes.

MARYAM YAVARI, MD, PH.D., ND NMT150 2023 LEARNING OBJECTIVES Considerations for providing nutritional guidance as it relates to this week’s case presentation: Addressing underlying causes Improving gut health Promoting healthy digestion TREATMENT GOALS Addressing underlying causes (e.g., food sensitivities, stress) Improving gut health Promoting healthy digestion DIETARY STRATEGIES FOR MANAGING GERD Avoiding trigger foods (e.g., acidic, spicy, fatty) Eating smaller, more frequent meals Consuming low-allergen, nutrient-dense foods General Recommendations Avoid eating before bed Eat slowly and chew thoroughly Sit up straight while eating Wait to exercise after eating General Recommendations Avoid trigger foods: Certain foods can trigger GERD symptoms. Some common trigger foods include spicy or fatty foods, acidic foods (such as citrus fruits and tomatoes), caffeine, and chocolate. It's best to avoid these foods or limit the intake. Limit alcohol and carbonated beverages General Recommendations Avoid eating before bedtime: eating a large meal before bedtime can increase the likelihood of acid reflux symptoms. It's best to avoid eating at least three hours before bedtime. Raise the head of the bed Chew gum Drink water  RECOMMENDED FOODS A systematic review of dietary interventions for GERD: The study included 72 articles from 10 Western countries and 9 Eastern countries. Dietary factors were categorized into 20 items and lifestyle factors into 11 items. GERD is related to irregular dietary and lifestyle habits, such as midnight snacking, skipping breakfast, eating quickly, eating very hot foods, and eating beyond fullness. https://pubmed.ncbi.nlm.nih.gov/33883899/  RECOMMENDED FOODS Vegetarian diets and no intake of meat were negatively related to GERD, while daily meat, fish, and egg intake, as well as high-fat diet consumption, were positively related to GERD. An interval of less than three hours between dinner and bedtime was positively related to GERD, while proper physical exercise was negatively correlated with GERD. Smoking, alcohol consumption, and poor mental state were positively correlated with GERD. Antioxidant intake was generally negatively correlated with GERD. https://pubmed.ncbi.nlm.nih.gov/33883899/  RECOMMENDED FOODS Intermittent fasting may be recommended, especially in overweight-obese patients with GERD symptoms who are poor responders to gastric acid inhibitors. https://www.medscape.com/viewarticle/984377#:~:text=%22Intermittent%20fasting%20may%20be%20recommended,work%20in %20patients%20with%20GERD.%22 SPECIFIC NUTRIENTS FOR GERD MANAGEMENT Magnesium Zinc Carnosine Vitamin 12  MAGNESIUM A population-based case–control study: individuals consuming the highest amounts of Mg from foods had significant reductions in the odds of reflux oesophagitis and Barrett’s oesophagus compared with individuals consuming the lowest amounts of Mg.

The Anti inflammatory diet is related to reduced inflammation levels. Higher levels of DII (from a proinflammatory diet) may play a role in the prevalence of LBP. 42% higher chances of having low back pain when comparing the group with the most proinflammatory diet to the group with the least pro-inflammatory diet. https://www.sciencedirect.com/science/article/abs/pii/S0165032722013106 https://www.rehabmedicine.pitt.edu/sites/default/files/enrico.pdf  What is an anti-inflammatory diet? Rich in vegetables, fruit, whole grains, nuts, legumes, unsaturated fats, spices and herbs A moderate intake of animal products A low intake of simple carbohydrates, processed foods, saturated fats and alcohol The Mediterranean diet, DASH diet and vegetarian dietary patterns have been described as examples of anti- inflammatory diets.

This results in an increase in arachidonic acid production. On the other hand, glucagon has a inhibitory effect on the desaturase enzymes, which leads to a reduction in the production of arachidonic acid. GiuglianoDCerielloAEspositoK.

Research has demonstrated that maintaining a low ratio of omega-6 to omega-3 fatty acids, specifically below 5:1.12 can have beneficial effects on various health conditions such as cardiovascular disease, rheumatoid arthritis, and asthma.

Consuming a diet that is high in omega-6 fatty acids can lead to an increased risk of inflammation. Omega-3 fatty acids have anti-inflammatory effects. Unlike insulin, omega-3 fatty acids inhibit the delta-6 desaturase enzyme, which reduces the production of arachidonic acid. Omega-3 fatty acids can contribute to the production of anti- inflammatory eicosanoids called resolvins, which are involved in regulating the activation and movement of white blood cells.

Hydrogenation converts naturally occurring cis double bonds of unsaturated fats into trans double bonds, producing a solid fat with a high melting temperature and longer shelf life. TFA consumption adversely affects serum lipids due to its impact on liver function and lipoprotein metabolism. SimopoulosAP.

The type of fat in the protein source determines whether it is anti-inflammatory or pro-inflammatory. Animal protein has higher levels of pro-inflammatory ω-6 FAs, while anti- inflammatory protein sources have higher levels of ω-3 FAs. Fresh-water fatty fish, such as salmon, mackerel, halibut, sardines, and herring, are good sources of anti-inflammatory protein due to their high levels of ω-3 FAs. KozarskiMKlausAJakovljevicD et al.

Fitoterapia. 2010; 81(7): 715– 723.  Protein Sources Wild-caught fish and naturally grazing cattle are better sources of anti-inflammatory protein due to their lower ω-6:ω-3 ratios. Organically produced dairy and meats also contain higher levels of anti-inflammatory ω-3 FAs compared to non-organic sources. Cooking method is important, as high- temperature cooking or charring can produce pro-inflammatory compounds and increase cancer risk. KozarskiMKlausAJakovljevicD et al.

Fitoterapia. 2010; 81(7): 715– 723.  Protein Sources Soy legumes, non-soy-based legumes, and mushrooms are excellent sources of plant-based protein with anti-inflammatory properties. Soy has been shown to decrease inflammatory markers, while non-soy-based legumes have an inverse relation to high-sensitivity CRP. Phytoestrogens in soy, daidzein, and genistein contribute to its anti-inflammatory properties. Mushrooms contain polyphenols and other anti- inflammatory phytonutrients and should be cooked to reduce natural carcinogens and release more nutrients. KozarskiMKlausAJakovljevicD et al.

Fitoterapia. 2010; 81(7): 715– 723.  Carbohydrates An anti-inflammatory diet includes various types of carbohydrates, including whole grains. Whole grain carbohydrates with a low glycemic index are essential in an anti-inflammatory diet. It is important to choose whole grains that have all their original parts present, such as bran, germ, and endosperm. AjaniUAFordESMokdadAH.

Am J Clin Nutr. 2003; 78(3): 610S– 616S.  Carbohydrates Refined grains, which strip out much of the nutrients, should be avoided. Grains that have been processed via cracking or crushing should be limited due to their high glycemic index. Examples of whole grains include buckwheat, barley, rye, and wild rice. Whole grains are high in fiber, which has been shown to reduce inflammatory markers. AjaniUAFordESMokdadAH.

Am J Clin Nutr. 2003; 78(3): 610S– 616S.  Healthy Fats The anti-inflammatory diet emphasizes on anti- inflammatory fats, which can be present in fruits, vegetables, and protein or added through supplementation of ω-3 FAs. Cold-water fish like salmon, sardines, and anchovies are some of the protein sources with high levels of ω-3 FAs. Fish oil, which is a potent inhibitor of inflammation, can be added as a supplement to an anti- inflammatory diet with a recommended dosage of 1000 mg three times a day. RongYChenLZhuT et al.

Trans fats, which are proinflammatory, should be avoided, and olive oil is the best choice when used at low temperatures for cooking, while oils like soybean, cottonseed, peanut, and corn oil should be avoided as they are proinflammatory.
