The ketogenic, Supraketo for Ketosis or keto, diet has a lot of people talking, so we wanted to know what the hype was about - and what you should know about the hot diet. We turned to Maria Petzel, senior clinical dietitian for the Pancreas Surgery Program at MD Anderson Cancer Center and an emeritus member of PanCAN’s Scientific and Medical Advisory Board, for answers. PanCAN: Supraketo.org What Is the Keto Diet? Petzel: What many people are calling a keto diet lately is actually just a low-carb diet - more like Atkins or South Beach. A true ketogenic diet, which is designed to achieve ketosis, must be extremely low in carbohydrates (about 5 - 10% of calories would come from carbs), controlled in protein and extremely high in fat. In a low carb diet like the South Beach Diet or Atkins Diet, about 20 - 30% of calories come from carbs, and protein isn’t restricted. In comparison, in a typical healthy diet, 45 - 65% of calories come from carbohydrates.

PanCAN: Does It Help You Lose Weight? Petzel: The key to burning body fat is to eat fewer total calories (from any source) than you take in. For those losing weight on a ketogenic diet, it is because they have a deficit of calorie intake compared to calories burned. Often, being in ketosis will suppress the appetite, leading to lower total calorie intake in general. PanCAN: Is It Safe? Petzel: We do not know much about the long-term effects of the diet. There are concerns that it could be harmful to the heart and liver. The lack of fiber in the diet can lead to issues with constipation, which could exacerbate other conditions like diverticulitis. Following a diet that basically cuts out an entire nutrient category - and therefore almost all grains, beans and lentils, most fruits, and some vegetables - can lead to vitamin and mineral deficiencies. PanCAN: What Should Pancreatic Cancer Patients Know About Keto? Petzel: If patients are on pancreatic enzyme replacement therapy, they will likely need to adjust their enzyme consumption to account for the increased dietary fat. Higher fat diets, like keto, can be harder to tolerate for some patients with pancreatic cancer, even with enzyme adjustment. Also, the level of fat required for a true ketogenic diet has the potential to displace adequate protein intake. Overall, the ketogenic diet poses a high risk of weight loss in patients, especially for those experiencing fat malabsorption. "We recommend that adults eat a plant-based diet that includes a wide variety of plant proteins from nuts, seeds, beans and legumes, whole grains, non-starchy vegetables and fruit," Petzel says. "We recommend adults get at least five servings of fruits and vegetables a day, along with plant proteins and whole grains adding up to at least 30 grams of fiber per day.

Salmon roe is here. There are many names for caviar from fish eggs to roe. Some of you guys might have gone to a sushi restaurant and seen ikura, masago or 2b go on the menu, but caviar is technically supposed to be from wild beluga sturgeon in the Caspian Sea. Now caviar is used as a general term for any salted fish eggs. What they do is they take the egg sac out of the fish. They separate the eggs from the membrane they lightly salt them, and then they either put it in jars or cans. Freeze, it refrigerate it whatever caviar might just be the healthiest food on the planet. Just like liver, it contains all of the vitamins, minerals, elements and fatty acids. Our bodies need, in their most bioavailable form the animal form. The nutrients in certain plant foods require conversion in the body, whereas the nutrients from animal foods are directly absorbed.

The main discrepancy between liver and fish eggs is that liver has a substantially higher vitamin A retinol content and fish eggs have much higher omega-3 fatty acids. Epa and DHA. The DHA in fish eggs is actually in the phospholipid form, which is said to pass through the brain, much easier and be absorbed better, but that’s never actually been proven. In a study I found out about fish eggs in Weston prices, book nutrition and physical degeneration. It’s a book about a dentist who explore native people that were still living off of the land, their natural diets. These people actually used fish eggs as fertility and nutrition for pregnant women, nursing women, children during developmental stages for its incredibly high nutrient content. If indigenous groups did not have access to fish eggs, they would always have another high nutrient food, maybe some type of shellfish, fatty insect or organ meat in Alaska. When food is plentiful, full and bears have fattened up, they actually killed the salmon and only eat the brain and the eggs of the salmon.
