Almonds versus complex carbohydrates for weight loss

Many people avoid eating nuts because of their high fat content. They are afraid they will gain weight if they eat nuts, and may instead eat low fat, high carb foods. This may sound like nonsense to some of you, but is this fear justified at all? I found a very interesting study which compared eating almonds with eating complex carbohydrates for weight reduction. According to City of Hope National Medical Center, Duarte, CA, in Almonds vs complex carbohydrates in a weight reduction program:

CONCLUSION:

Our findings suggest that an almond-enriched LCD improves a preponderance of the abnormalities associated with the metabolic syndrome. Both dietary interventions were effective in decreasing body weight beyond the weight loss observed during long-term pharmacological interventions; however, the almond-LCD group experienced a sustained and greater weight reduction for the duration of the 24-week intervention. Almond supplementation of a formula-based LCD is a novel alternative to self-selected complex carbohydrates and has a potential role in reducing the public health implications of obesity.

The conclusion was the opposite of what many people believe. This may be due to the fact that on average we only absorb about 70% – 80% of the calories from nuts. This is largely due to their high fiber content. In general, people who eat the most nuts tend to be slimmer and healthier on average. And don’t forget that the fat in most nuts, in particular almonds, is the healthy kind.

Why eating nuts can help you lose weight

Radioactive Brazil nuts and the naturalistic fallacy

Believe it or not, just about all the food we consume has tiny amounts of radioactivity. Some foods contain more than others. While a small amount of it is due to nuclear fallout and industrial pollution, most of it is naturally occurring, since radioactivity is a natural phenomenon.

Brazil nuts by far are the most radioactive of all food. According to Wikipedia:

Brazil nuts contain small amounts of radium. Although the amount of radium, a radioactive element, is very small, about 1–7 pCi/g (40–260 Bq/kg), and most of it is not retained by the body, this is 1,000 times higher than in other foods. According to Oak Ridge Associated Universities, this is not because of elevated levels of radium in the soil, but due to “the very extensive root system of the tree”.

Even though Brazil nuts are a lot more radioactive compared to most foods(due to its deep, extensive roots), this doesn’t mean we should avoid them. The amount is way too small to have any permanent effects. This radioactivity in Brazil nuts is naturally occurring, not due to nuclear fallout.

Brazil nuts are an excellent source of selenium, an important mineral that some preliminary studies suggest may help prevent cancer, among other things. Fortunately, selenium deficiency is rare in most developed countries.

I think this also goes to show that eating “natural” doesn’t mean you are somehow avoiding very toxic substances. Radiation is perfectly natural, and so are lead and mercury, which are also present in trace amounts in the food and water supply. Luckily, these toxins tend to get quickly removed by the body.

While eating healthy usually means eating more “natural”(less processed foods, more whole/unprocessed foods), many health-nuts take this to extremes and buy into some form of the “naturalistic fallacy” to justify their dietary habits. This is especially true of people who follow a rawfood vegan diet, and also the followers of “paleo” diets.

At its most basic, the naturalistic fallacy means equating “natural” with being inherently good, safe, or desirable, while something “unnatural” is seen as inherently bad, or undesirable. Ask a rawfoodist to explain why they believe their diet is so much better compared to the way most people eat, and their answer ultimately boils down to: “It is more natural”. Cooked food is “unnatural”(what other animals cook their food?), so cooked food is bad; food in its raw, “natural” state is good.

This doesn’t mean there is no truth to the arguments in favor of eating raw. For instance, it is true that many nutrients are destroyed while cooking at high temperatures. On the other hand, many other nutrients are less bio-available in raw foods. It must also be noted that cooking helps destroy many anti-nutrients like oxalates or phytates that can interfere with the absorption of important minerals like iron(this is why raw spinach with its high oxalate content is a poor source of calcium and iron). This explains why you can’t eat beans raw(of course you can try to do it, but I wouldn’t advise it). While some foods like salad greens, nuts, and fruit are best eaten raw, many other foods, like legumes and grains have to be cooked.

While we should minimize our consumption of processed foods, and of both natural and synthetic toxins, we shouldn’t go overboard and panic if we discover something contains trace amounts of a toxic substance. Similarly, we shouldn’t demonize something just because it may contain something that is “unnatural”. Dogmatic black and white thinking is not helpful when it comes to healthy eating.

You get most of your protein from nuts?!

Rumors have been swirling around about this for quite some time. I thought it was time to tell the truth. I do, in fact, on many days get most of my protein from nuts. Or a delicious combination of nuts and legumes. The Wild Juggler is in fact a vegetarian.

So how is this possible? Is he, yet again, violating the laws of physics? Truth be told, nuts are a great source of protein.
1/4 cup of almonds contains about 6 grams of protein.

While it also has a lot of fat, it is mostly the healthy, unsaturated kind of fat. Almonds and many other nuts are also good sources of fiber, minerals, and protective phyto-chemicals, similar to the ones in tea and some vegetables. I love my nuts raw and unprocessed. I don’t eat nuts that have added oils, salt, sugar or anything. Read labels. I often snack on nuts after a long joggle.

If you’re afraid that eating nuts will cause weight gain, do not worry. I eat tons of nuts almost every day; if you’ve been pecan at my photos, you know I’m not exactly obese. Still not convinced?

According to Fitwatch.com, eating nuts regularly can help you lose weight by speeding up your metabolism – Why Eating Nuts Can Help You Lose Weight

Fiber, always your friend, helps prevent the fat from getting absorbed. I think nuts are a great way to replace meat and dairy in your diet. People who eat a lot of nuts are generally slimmer, on average than those who eat the least. Nut butters make a great snack and are good for making sandwiches. Peanut butter is one of my favorites, though technically, peanuts are a legume.

I totally love nuts. When people call me a “nut”, I take it as a compliment. So go nuts with nuts, and try to violate the laws of physics with your fitness routine!
