Your abs are made in the gym and revealed in the kitchen. A good training program develops the muscles in your midsection and the right diet helps banish bloating so you can see your abs. Here are the 10 flat belly foods you should add to your diet for a better looking (and better feeling) mid-section):Greek yogurt for belly fat

Greek Yogurt with Live and Active Cultures

Look for Greek yogurt with “live cultures (aka good bacteria)” or the “Live & Active Cultures” seal. The cultures are good bacteria that take up valuable real estate in your gut, helping your body digest food and decreasing gas and bloating. The amount of healthy, versus harmful, bacteria influences body weight and how much weight you can lose while following a lower calorie diet. Plus, a study published in the International Journal of Obesity found people who get their calcium from yogurt, as opposed to other foods, may lose more weight in their belly. Even more evidence to support yogurt consumption comes from a study showing dieters who ate five servings of dairy, such as Greek yogurt, daily lost more weight and abdominal fat than those who ate just three servings every day. A more recent review of the research found higher dairy intake was associated with lower risk of obesity in the midsection and yogurt seems to help keep weight in check.

2 Nuts

Though nuts are relatively high in calories for a small amount of food,  people don’t gain weight when they add nuts to their previously nut-free diet. A study in over 13,000 adults revealed nut eaters, those who ate at least ¼ ounce of nuts or peanuts (technically a legume) per day had smaller waists than adults who didn’t eat nuts. Additionally, tree nuts and peanuts contain a considerable amount of monounsaturated fat. Dieters who eat more foods containing monounsaturated fats may lose more belly fat than those who eat the same number of calories per day with less monounsaturated fat.

3 Asparagus

When examining dietary patterns, weight and waist circumference in close to eighty thousand people over a 10-year period, researchers found those who ate more vegetables every day had both a lower BMI and smaller waistline compared to adults who ate few vegetables. Asparagus contains prebiotic fiber, a type of fiber that is food for the good bacteria in your gut. Plus, asparagus is a natural mild diuretic making it the perfect food before hitting the beach or wearing a more formfitting outfit.

4 Avocados

Avocados contain a good amount of monounsaturated fat, not to mention nineteen vitamins and minerals. But, their monounsaturated fat is the ticket to a smaller waistline. In one study scientists gave obese adults with type 2 diabetes diets rich in saturated fat, monounsaturated fat or  carbohydrates. Those on the high carbohydrate diet ended up with fat redistributed to their stomachs while the monounsaturated fat rich diet prevented fat redistribution to the belly area. Plus, a look at dietary intake data from close to 18,000 adults found body weight, BMI and waist size were all significantly lower in avocado consumers versus those who didn’t include avocados in their diet.

5 Popcorn

Popcorn is a whole grain and when you pop it yourself on the stovetop (or in a brown paper bag in the microwave, just add good old fashioned popcorn kernels in a brown paper bag and fold the top) and top it with a little spray butter or spices for flavor, you’ll end up with a snack that takes a long time to eat and fills you up on relatively few calories. In addition, several studies show people who eat about three servings of whole grains per day weight less and have a smaller waistline compared to those who don’t.

6 Cold Pea Salad

Peas are naturally rich in resistant starch, a type of fiber that isn’t completely broken down or absorbed during digestion. Cooking and cooling peas to make a pea salad will significantly increase the amount of resistant starch they content. Rodent studies show resistant starch helps reduce stomach fat and increase hormones that tell the brain it’s time to stop eating.

7 Eggs

Choose eggs over cereal in the morning and you’ll tame hunger pangs for hours after breakfast, decreasing the likelihood of overeating later in the day. Make a meal containing at least 25 – 30 total grams of protein (the protein is in the white of the egg so this equates to 4 – 5 egg whites though you can choose any combination of whole eggs and egg whites as long as you consume at least 4 -5 of the whites) so you can cash in on the satiety-enhancing benefits of eggs. Added bonus: following a high protein diet for a short period of time can lead to significant reductions in belly fat.

8 Green Tea

The combination of caffeine and antioxidants in green tea may lead to small to moderate reductions in body fat and waist size. However, you need to consume quite a bit of it so get creative and cook with green tea by brewing it and using it to cook rice (it’s particularly good with jasmine rice), make stews, soups or stocks. You can also poach fruit green tea or use dried green tea leaves as part of a rub for meats, tofu or fish.

9 Barley

Barley is a cereal grain with a nutty taste and consistency that is a cross between pasta and rice. In a double-blinded trial (both the men and the researchers didn’t know which food they were getting), Japanese men were given rice or a mixture of rice with pearl barley. The group receiving the pearl barley and rice mixture lost a significant amount of visceral fat, the kind that covers your organs like a thick winter blanket and increases risk of heart disease, stroke and type-2 diabetes. Compared to the rice only group, the group who ate pearl barley decreased their waist size.

10 Blueberries

Blueberries are an excellent source of dietary fiber, which will not only help keep you full but also help keep your waistline in check. Plus they are a natural source of prebiotic fiber – the kind that the good bacteria in your gut munch on.

A flat belly is one of the most recognized signs of a fit body. Blast away abdominal fat with high-intensity cardio and build the underlying muscle by regularly switching up your training program. Also, incorporate a 30-minute abs classes to your routine. At least one study found you can spot reduce if you exercise the same muscle group for at least 30 minutes at a time. Keep in mind abs are made in the gym but revealed in the kitchen. Add the top 10 flat belly foods to your diet while cutting down on sugar alcohols (sorbitol, maltitol, and mannitol are the worst for causing gas and bloating), fizzy drinks and chewing gum (all of these can increase bloating at least temporarily) and you may fall in love with skinny jeans.

Is Saturated Fat Good for You?

Though largely driven by misinterpretation of the science and cherry-picked population studies, the “Butter is Back” movement comes with very persuasive sound bites followed by arrogant punctuation marks. No wonder so many people hopped on board the bandwagon while looking back, pointing fingers and shouting “health professionals have been misleading us for decades!” Yet the flawed reasoning behind the pro-saturated fat movement comes with a hefty price tag – you could be making food choices that, over time, will increase your risk for cardiovascular disease and type 2 diabetes.

Here’s what I’ll cover in this article:

  • Why is there so much confusion about saturated fat?;
  • The science behind saturated fats, cardiovascular disease (diseases of the heart & blood vessels) and type 2 diabetes;
  • Best food choices for heart health.

Why is there so Much Confusion about Saturated Fat?

There are a few reasons for the confusion about saturated fat (fat that is solid at room temperature such as butter, shortening, coconut oil and the fat on meat) and misinterpretation of the science. First off, some people group all saturated fatty acids (saturated fatty acids make up saturated fat) together as a team. However, there are several types of saturated fatty acids. Some raise LDL cholesterol (the kind that contributes to clogged arteries and is a risk factor for cardiovascular disease) as well as HDL cholesterol (“good” cholesterol, the kind that removes bad cholesterol; SN: drugs that increase HDL do not lower risk of heart disease so there is some considerable debate regarding the role of HDL), others don’t raise LDL cholesterol and some we aren’t quite sure about. Secondly, using population-based studies alone to draw conclusions about saturated fat intake and heart disease is misguided.  These studies are not designed to determine cause and effect (that’s the job of well-designed clinical trials) plus, there are inherent issues with the methods used in many of these studies.  Nutrition research is not easy, especially in humans living their life (those not in a metabolic ward where all factors are controlled and measured including diet and physical activity).

Lastly, some research studies (and the media) take the results way out of context. So, here’s the lowdown based on sound science:

The Science Behind Saturated Fat, Cardiovascular Disease and Type 2 Diabetes

  • There is no dietary requirement for saturated fat. Your body can make all of the saturated fatty acids it needs.
  • Foods high in saturated fat typically increase total, HDL and LDL cholesterol. However, the impact dietary saturated fat has on increasing LDL-cholesterol (the kind that contributes to clogged arteries and an inflammatory cascade in arteries) may depend on the amount of polyunsaturated fat (PUFAs) in your diet (as well as the type of saturated fatty acids consumed).
  • In general, replacing saturated fat with polyunsaturated fat (and monounsaturated fat though there is less evidence for monounsaturated fat) reduces LDL and total cholesterol, both risk factors for cardiovascular disease.
  • saturated fat and cholesterolOverweight, obesity and insulin resistance may reduce the beneficial effects (lowered LDL cholesterol) generally noticed from a reduction in saturated fat intake. *If obese or overweight, losing excess body fat (regardless of the type of diet used to lose the weight) has powerful effects on lowering risk for cardiovascular disease, some cancers, and type II diabetes.
  • Food contains a complex mixture of compounds that may affect cholesterol and cardiovascular disease risk (it is not just the fat). The food “matrix” matters.
  • Many factors impact how a food affects cholesterol and blood lipids (fats) including fats eaten at the same time, overall diet, and carbohydrate intake (and type of carbohydrates consumed – high fiber vs. foods high in added sugar with few other nutrients).
  • There are individual, genetic differences in response to saturated fat intake – your cholesterol might shoot up after eating a diet containing a diet high in the type of saturated fatty acids that raise LDL cholesterol and I might be able to get away with this diet without a problem (blame your genetics or consider it an opportunity to open your taste buds to foods containing less saturated fat; particularly the kind that is artery clogging).
  • Certain saturated fatty acids, or a diet high in saturated fat, may increase risk for type 2 diabetes.

Best Choices for Heart Health

If you are overweight, focus on losing excess body fat. Even small amounts of fat loss will improve health and risk factors for cardiovascular disease. If you have high total and LDL cholesterol, swap foods high in saturated fat for foods high in polyunsaturated fat (liquid oils, nuts, seeds, olives, avocados). Minimize your intake of foods high in added sugars and refined, white flour, carbohydrates. Instead, choose higher fiber carbohydrates as often as possible.

Don’t get sucked into the media headlines written by journalists who could sell ice to an eskimo. Butter isn’t back (for good health anyway). The bulk of your fat intake should still come from foods that are higher in polyunsaturated and monounsaturated fats. However, food is a complex matrix of compounds and therefore, some foods higher in saturated fat may have little to no impact on cholesterol and therefore fit into your diet while contributing to your vitamin and mineral needs and providing plant-based compounds important for good health.

Is Coffee Good for You?

CoffeeDrinking coffee will leave you dehydrated and geeked out on caffeine. For several decades we’ve been warned about America’s favorite beverage. Yet these dire warnings were largely based on assumptions rather than actual science. A growing body of evidence suggests your morning Cup O’ Joe may be good for you! Here’s a look at the latest research.

What’s in a Coffee Bean?

Coffee beans are actually seeds from coffee cherries. They are picked, dried, and roasted turning them from green to those familiar aromatic brown beans we know and love. It’s ironic that a beverage made from seeds has gotten such a bad rap. Green coffee beans are naturally rich in antioxidants including chlorogenic acids, compounds that are readily absorbed in the human body, have antibacterial and anti-inflammatory actions and are associated with many health benefits including a reduction in cardiovascular disease, type II diabetes and Alzheimer’s disease. Antioxidants protect plants from disease and pests. Some antioxidants also protect human cells from harm. Roasted coffee beans are loaded with antioxidants (contrary to popular belief, they are not destroyed during roasting) and scientists are slowly uncovering the metabolic fate of each type antioxidant as well as the potential health benefits associated with regular coffee intake.

Potential Health Benefits

A National Institutes of Health study published in 2012 found older adults who drank caffeinated or decaffeinated coffee were less likely to die from heart disease, respiratory disease, stroke, injuries and accidents, diabetes, and infections. Those who drank over 3 cups per day had a 10% lower risk of death compared to those who did not drink coffee. Though this study only showed an association between coffee consumption and a decreased risk of death, it provided some reassurance to people who couldn’t seem to give up their favorite beverage. Studies published over the past three years lend strength to the relationship between regular coffee intake and a decreased risk of certain diseases.

Heart Health
A study published in the British Medical Journal’s publication Heart, examined diet and artery health in over 25,000 Korean men and women. Those who drank 3 to 5 cups of coffee per day were 19% less likely to have the first signs of atherosclerosis,  plaque buildup on artery walls, compared to those who were not coffee drinkers. Lower intakes were not associated with a reduction in plaque buildup. Drawbacks to this study: diet was examined at one point in time and study subjects were asked to recall their coffee intake over the previous year (people generally don’t recall their food / drink intake with great accuracy). Also, keep in mind this study showed an association between coffee intake and artery health, it doesn’t prove that coffee reduces plaque buildup on artery walls or that it can prevent cardiovascular disease. More research is needed to understand how coffee intake could potentially support heart health.

Cancer
A recently published study found individuals previously treated for stage III colon cancer who were regular coffee drinkers, consuming at least 4 cups of caffeinated coffee per day, had a 42% lower risk of recurrence of colon cancer and 33% lower risk of dying from the disease. This study found an association between coffee intake and decreased risk of colon cancer recurrence.

Research on coffee intake and risk of various cancers is mixed with some showing it is protective and others suggesting it may increase risk. Keep in mind there are many potential factors that impact cancer risk and risk of cancer recurrence with a sedentary lifestyle, high body fat and alcohol intake strongly associated with increased risk of certain types of cancer. Fruit and vegetable intake is associated with a decreased risk of some types of cancers. As for your Cup O’ Joe, time and more research, will tell us how America’s favorite beverage fits in the picture.

Should You Increase Your Coffee Intake?

All of these studies on regular coffee consumption include higher intakes. No benefits are noted for lower intakes – one to two cups per day. Keep in mind that some people should avoid or be cautious with caffeine intake including kids, teens, people with anxiety disorders, glaucoma, heartburn or cardiovascular disease. Also, pregnant women should avoid higher intakes of caffeine – more than 3 cups of coffee per day (regular sizes cups). Now about the caffeine – regular intake of moderate amounts of caffeine will not dehydrate you.

If you drink coffee in moderation, enjoy it! Don’t increase your intake based on these studies or start drinking if you aren’t a regular coffee consumer. Future research will tell us more about the many naturally occurring compounds in coffee, their actions in the body and the potential link between coffee and disease risk.
